1942
: USS GURNARD (SS 254)

On the prowl in enemy-controlled waters, USS GURNARD left a trail of destruction in her wake. During nine war patrols in World War II, the underseas marauder sent twelve enemy ships to the bottom and severely damaged twelve others.

Built by the Electric Boat Company, Groton, Connecticut, GURNARD's keel was laid on 2 September 1941. Nine months later, on 1 June 1942 she slid down the ways. The submarine was sponsored by Miss Suzanne Slingluff, daughter of Commander and Mrs. Frank Slingluff, USN (Retired), of Washington, D. C. The sub was named for a species of marine, spiny-finned fishes with armored heads and bearing three pairs of finger-like feelers. GURNARD was commissioned on 18 September 1942, with Commander C. H. Andrews, USN, as her first commanding officer.

After a six-week shakedown and training period at New London, Connecticut, GURNARD took departure on 2 November 1942 for Base Two, Rosneath, Scotland, to commence offensive operations against the enemy. The sub arrived at Rosneath on the 15th, and following her refit, she churned out of Rosneath on 28 November, enroute to the Bay of Biscay off the Spanish Coast for her First War Patrol.

On this uneventful patrol the sub contacted only frer i1y ships and after spending 24 days on station she returned to Rosneath on 27 December, thus completing her first war patrol.

Major engine repairs completed, GURNARD stood out of Rosneath on 25 January 1943, enroute to New London. Following her arrival at New London on 9 February, the submarine underwent a refit during which all the latest alterations were installed. GURNARD proceeded to Pearl Harbor via the Panama Canal for duty with Submarine Force, Pacific Fleet, arriving at Pearl Harbor on 26 May.

Voyage repairs and training completed, the submarine stood out of Pearl Harbor on 12 June, enroute to her Second War Patrol off the Palau Islands via Midway.

GURNARD moored at Midway on 16 June, departing there the same day after topping-off fuel and provisions. Arriving in her assigned area on 27 June, the sub commenced patrolling and on 29 June at 1020 while off Toagel Mungui Passage, contact was made with an eight-ship enemy convoy, consisting of six merchantmen, escorted by two destroyers. Closing the convoy, which was preparing to enter the passage, GURNARD expertly maneuvered herself into position with her bow tubes on a freighter and her stern tubes on another. At 1230 she fired a spread of three torpedoes at each ship, scoring three hits on the first target and one on the second. Splashes of projectiles were seen close aboard the sub and one of the destroyers was seen heading directly for her. While diving, a last glance was caught of the first target which was dead in the water and smoking heavily.

While rigging for depth charge attack, many breaking-up noises were heard from the torpedoed ships, indicating that one was shtiking and the other was severely damaged. GURNARD was subjected to a twenty-four missile depth charge attack before she could clear the vicinity.

The following day (1 July), while still in the same area, GURNARD made contact with four enemy merchant ships with six escorts and she commenced closing. Upon coming to periscope depth, a large escort was sighted only 500 yards distant and beyond, at 2,200 yards were the four merchantmen in ragged column. The underseas raider hove into position and fired a spread of three torpedoes at the destroyer, swung about, and fired another three-missile spread at the largest merchant vessel.

Shortly after firing the second salvo, a torpedo hit was seen on the destroyer which blew up with dense black smoke covering the area where she had been. The second salvo was equally lucky, with one hit being scored on the intended target and a third hit ripped into another merchant ship which had maneuvered into the path of a torpedo. Both ships were left badly damaged. Further observation was hampered by the black smoke from the sunken escort and the sub was forced to seek the depths when four small aerial bombs exploded close by.

GURNARD headed toward the center of the convoy where the enemy escorts would have a difficult job tracking her and while running deep, she was subjected to a 33-charge depth charge attack, which was close enough to rock her conning tower. Following a short period of silence, the sub commenced her reload, only to be halted by another depth charge barrage.

Going still deeper, the anti-sub vessels were evaded by brilliant evasive tactics. GURNARD was forced down once again by more depth bombs. However, after she had eluded the escorts she came to periscope depth at 1122, and incredible as it seems, she sighted a Japanese aircraft carrier with air escort.

An unlucky maneuver for the Jap, brought the carrier into a set-up shot for the sub, range 1,800 yards. Upon gaining position, GURNARD fired a spread of three torpedoes at the huge target, scoring two hits. The sub was forced down by the escorting Jap planes which were dropping bombs all about the underseas marauder. However, before going deep a last look at the carrier revealed that she was dead in the water, with a 25° list and smoking heavily. The sub swung about and fired a torpedo from her stern tubes at the stopped target, before going deep.

Shortly after submerging, a timed hit was heard on the carrier, followed by tremendous internal explosions, indicating that the target was sinking. After reloading her tubes, GURNARD again headed for the area of the halted target. However, upon reaching periscope depth, no trace of the vessel could be found.

After a short search, contact was made with two enemy escorts, and the sub cleared the area to the northwest to check for damage. GURNARD commenced patrolling the northwest sector of her area, working her way down to Toagel Mulungui Passage.

On 6 July, while off this passage, two depth bombs landed very close aboard the sub causing momentary loss of power on her diving planes. The underseas'raider immediately took a steep up angle and after a terrific struggle, her upward motion stopped, but then she dropped like a rock. While dropping, several depth charges were felt before depth control could be regained and the sub finally cleared the area after incurring extensive minor damage.

GURNARD sighted four enemy cargo ships with an escort at 0254 on 11 July and commenced closing the convoy. Taking advantage of the break of dawn, which left the convoy silhouetted against the horizon, the underseas marauder swung into position at 0445 and fired a spread of torpedoes at the fourth ship in column, scoring no hits.

The now alerted enemy started maneuvering violently, and the submarine swung around to bring her stern tubes to bear. In position, she fired a spread of four torpedoes at the second and third ships in column, which were overlapping, scoring one hit on each target. The third vessel in column immediately started to break up and sag in the middle, and shortly thereafter there was no trace of her on the surface. The second ship was severely damaged, but was able to make headway. By this time gun flashes from the other two ships were evident and the escort was heading directly for GURNARD, forcing the sub to seek the secluding depths.

While using evasive tactics beneath the surface, nine in-accurate depth charges were felt during the next ninety minutes. At 0610 the sub was finally able to take a look around, sighting the remnants of the enemy convoy in the distance. With all torpedoes expended, GURNARD headed for Midway.

Following a one day refueling stop at Midway on 22 June, the sub proceeded to Pearl Harbor, arriving there on the 26th, thus completing a successful war patrol.

Refit completed, GURNARD stood out of Pearl Harbor on 6 September 1943 enroute to the South China Sea for her Third War Patrol via Midway.

A one-day refueling stop was made at Midway on 10 September, and then the sub coursed toward her assigned patrol grounds. While enroute, on 18 September, the underseas raider made contact with an enemy merchant ship, escorted by a destroyer. However, while she was making her approach, she was forced down by an intense depth charge attack which caused little damage but enabled the enemy to escape.

GURNARD entered her area on 22 September and on the 30th, while patrolling the shipping lanes north of Pescadores Channel, she sighted an unescorted Japanese cargo ship. The sub commenced closing

— page 6 —

the target and, in position, she fired a spread of four torpedoes scoring two dud hits on the vessel. After another unfruitful attack on the enemy ship, GURNARD was forced to seek the depths upon the arrival of an enemy escort from a convoy in the vicinity. While running deep, she was subjected to an intense depth charging from the attacked vessel as well as the escort, but excellent evasive tactics brought her clear of the enemy.

At 1112 on 7 October, GURNARD sighted smoke on the horizon which developed into a two-ship contact, and she commenced tracking the enemy vessels. Shortly thereafter, two more Jap cargo ships joined the convoy, and then one escort. Finally at 0139 on the 8th, the sub swung into position and fired a spread of four torpedoes at the leading merchant ship in column. She then swung around and shot a four-torpedo spread from her stern tubes at the second ship in column.

Two hits blasted the first target and when last sighted only the stern was in sight. The second target took three torpedo hits, blew up and split in two, then plunged to the bottom amid loud explosions. The sub was quickly taken under fire by the remaining ships, and with the enemy fire just above her, she ran for cover at full speed toward a dark horizon.

GURNARD managed to avoid the searching escort for some time, seeking a position to strike again at the convoy. However, every time she started closing, the escort would block her path, and finally the sub lost contact with the two surviving merchantmen. Clearing the area at full speed, GURNARD went deep when an enemy land-based bomber was sighted.

While on patrol, at 2225 on 9 October, the underseas raider made radar contact with a Japanese merchant ship, and commenced her approach. The sub dove and closed the target, gaining position at 0120 on the 10th, when she fired a spread of torpedoes at the vessel. Two hits were observed on the target, but both appeared to be weak explosions as the noise was less, the flash was less, and the amount of water blown up was less.

GURNARD surfaced, and commenced chasing the still fast-moving target, and upon gaining position; the sub conducted two more attacks on the target, scoring weak hits, similar to the first attack. Having now expended all her torpedoes, the sub was forced to abandon the chase, leaving the apparently slightly damaged ship escape.

Arriving at Midway on 24 October, GURNARD departed the same day, heading toward Pearl Harbor. She moored at Pearl Harbor on the 28th, thus completing a successful patrol.

Following her refit, GURNARD stood out of Pearl Harbor on 28 November 1943, enroute to the waters off the southeast coast of Honshu, Japan for her Fourth War Patrol. Arriving at Midway on 2 December, the sub underwent repairs to a faulty engine, and on the 7th she departed Midway, heading for her assigned area. Heavy seas

were encountered while enroute, causing the sub to be three days late in entering her "hunting grounds."

On 22 December at 2040 the surfaced submarine made radar contact with a Japanese merchant ship with three escorts and commenced her approach. Upon gaining position, at 2118, the sub fired a spread of four torpedoes, scoring one hit amidships on the target leaving it dead in the water.

GURNARD drew out of range of the circling escorts which were firing around the horizon to prevent the sub from reclosing the damaged vessel. While observing this display of fireworks, the sub made contact with a five-ship enemy convoy, and, as it was impossible to close the damaged ship now, she commenced tracking the convoy. During the night of 22-23 December, the surfaced sub made three unfruitful attacks on this convoy.

While closing for a fourth attack aft of the target, the sub was shaken badly by a depth charge which the enemy had dropped, hoping that the sub would pass over it. As GURNARD was now without shore objects to pilot on, her position very much in doubt and as she was 40 miles into a friendly submarines patrol area, she broke off her attack.

The following morning (24 December) at 0400, GURNARD made radar contact with three large enemy merchant ships with three escorts and commenced closing them. In position, at 0710 the sub fired a brace of torpedoes at the leading merchantman, scoring two hits on the target, which broke in two and sank in two minutes. The other merchantman started maneuvering radically, forcing the sub to clear out of their way. However, an unlucky enemy maneuver lined up the sub's stern tubes on the second merchant ship, and the sub fired a brace of torpedoes. Two hits were scored on the target which plunged to the bottom in a minute's time. Both of the sunken ships were heavily laden; the first was a collier of about 5,000 tons and the second a 6,000 ton ship.

Still trying to close the remaining ships, GURNARD was forced down by the onrushing escorts. While taking evasive measures, five anti-sub vessels were heard by the sub's sound gear, all hunting the underseas raider. During this depth charging, the enemy used 88 charges in their futile attempt to exterminate GURNARD.

Clearing the vicinity, the submarine continued on patrol, and on 27 December at 2020, she made contact with a very large enemy merchant vessel, escorted by ten destroyers, which encircled the large ship. After many attempts at piercing the escort screen, the sub finally succeeded, and in position at 2350, she fired a spread of four torpedoes, scoring two hits on the target. GURNARD's last four torpedoes from her bow tubes left the enemy dead in the water, but fifteen minutes later, the damaged ship was able to get up steam and clear the vicinity.

All torpedoes expended, GURNARD headed toward Midway, and after a one-day stop there on 3 January 1944, she proceeded to Pearl Harbor, mooring at the Submarine Base on 7 January, thus ending her Fourth War Patrol.

Four days later, GURNARD stood out of Pearl Harbor bound for the West Coast for a major overhaul, arriving at the U. S. Navy Yard, Mare Island, California on the 18th. Following her yard availability, the sub returned to Pearl Harbor, where she conducted training operations.

On 16 April 1944, GURNARD stood out of Pearl Harbor enroute to her Fifth War Patrol in the eastern portion of the Celebes Sea. After a one-day refueling stop at Johnston Island on 18 April, the sub proceeded on course, entering her assigned station on 4 May.

Smoke was sighted at 0835 on 6 May, which subsequently developed into a large enemy convoy, consisting of eight enemy merchant ships, with six escorts. GURNARD commenced closing the convoy, coming in on the convoy's starboard beam. In position at 1300, the sub fired a spread of three torpedoes at each of the two vessels in the starboard column.

Two hits were scored on each of the two targets, and the other two torpedoes found their mark in two other merchant ships, both of which were overlapping astern of the original targets. The sub went to deep submergence when one of the enemy destroyers headed directly for her, rigging for depth charge attack on the way down. A very intense depth charging began, with the sub maneuvering to avoid the searching escorts. While running deep, many breaking-up noises were heard on her sound gear, indicating that the four targets were damaged and sinking. During a lull in the depth charge attack, GURNARD came to periscope depth to see the damaged targets all in a sinking condition with the escorts picking up survivors.

The escorts resumed their attack, causing the sub to go deep, and during this attack a total of 98 depth charges were dropped in a frantic effort to sink the sub. Still in the attacking area, the sub closed the last remaining damaged ship that was still afloat (the other three were believed to have sunk). At 0025 she fired 21 rounds of four-inch ammunition at the blazing ship with negative results. Finally, at 0043 on 7 May, the sub sent another torpedo into this burning target, which sank shortly thereafter.

GURNARD cleared the vicinity and made an unsuccessful search for the remnants of the convoy before returning to her own patrol area. At 0748 on 18 May, the submarine made contact with an enemy battleship, escorted by two destroyers, and commenced her approach.

The radically maneuvering targets were closed, and at 0809 the sub fired a spread of six torpedoes at the Jap battleship. Two hits were heard on the large ship, and the hunter then became the

hunted, as the destroyers commenced an intense and accurate depth charge attack on the sub. While GURNARD was held down by the escorts, all three ships were able to escape and upon coming to periscope depth, the sub sighted the fast withdrawing targets going over the horizon, removing any chance of catching them.

Clearing the area, the sub continued on patrol and on 24 May at 0925, she made contact with a four-ship Jap convoy, consisting of two cargo ships, with two escorts. After making an unsuccessful attack on the merchant ships, the sub was in turn subjected to an extremely accurate depth charge attack from the escorts.

At 1340 the same day, GURNARD sighted a seven-ship enemy convoy, consisting of two oilers and two cargo ships, with three escorts. After slipping past the "hot so alert" escorts, the sub hove into position at 1414. She fired a spread of four torpedoes at the closest ship to her, a very large tanker, scoring many hits which left the target blazing with flames shooting over 100 feet into the air.

GURNARD sought the depths to evade the escorts, and while submerged many breaking-up noises were heard from the attacked oiler; indicating that she was sinking. One hour and 27 depth charges later, she came to periscope depth to find the area clear, with the exception of one destroyer in the distance.

Clearing the vicinity, the sub sighted three enemy battleships with at least five other ships at 0857 on 31 May, but was unable to close the targets as they never came into range and were steadily pulling away from the sub.

The sub cleared her assigned patrol area and on 5 June she made a one-day refueling stop at Darwin, Australia, before proceeding to Fremantle, Australia. Following a six-day voyage, GURNARD moored at Fremantle on 11 June, ending her war patrol.

Refit completed, on 8 July 1944, GURNARD set course from Fremantle, enroute to her Sixth War Patrol in the Banda, Molukka, Celebes, Sulu and Mindanao Seas. The sub moved around the western and northern coast of Australia and on the 15th she moored at Darwin, Australia, where she refueled, before departing the same day. She proceeded to her area, and on 27 July at 1255, while patrolling off the Peleng Straits, the sub made contact with a seven-ship Jap convoy consisting of three cargo ships with four escorts.

The convoy was maneuvering radically, making GURNARD's approach doubly difficult, and at one time, while attempting to gain position, an enemy change of course brought two of the cargo ships and one escort directly over her. Finally in position, at 1437 she fired a spread of three torpedoes at the first cargo vessel in the starboard column.

Swinging to the starboard, the sub fired her three remaining bow torpedoes at the second ship in the starboard column. No hits were scored on the first target and while firing on the second, it

— page 10 —

was seen that the propeller of #1 target was awash, thus explaining that the ship was riding light, causing the torpedoes to pass beneath her.

Two hits were scored on the second target, but they seemed to cause little damage as it didn't change course, slow up, break up, or even settle by the bow. Two enlisting escorts forced GURNARD deep and commenced a depth charge attack which caused much minor damage to the sub.

At 1635 she came back to periscope depth to find only one anti-sub vessel in sight, and the sub then cleared the area, leaving the "sub-hunter" astern.

While patrolling off Strooman Kaap on 15 August, the sub conducted an unsuccessful attack on an enemy destroyer, and was quickly counter-attacked by the target. Excellent evasive tactics brought GURNARD clear of the "sub-hunter" and she continued on patrol. The sub conducted an unfruitful attack on a Japanese merchantman on 20 August, but was driven away by enemy air and surface escorts.

During the remainder of her patrol GURNARD sighted many small craft unworthy of attack and on two occasions she boarded two of these small boats to determine if they were being used as spotters. The sub proceeded through Lombok Strait and arrived at Fremantle, Australia on 5 September, thus completing her Sixth War Patrol.

Refit completed, on 9 October 1944 GURNARD stood out of Fremantle enroute to her Seventh War Patrol in the South China Sea.

After reaching her assigned area, on 21 October at 1222, while patrolling off Tanjong Datoe, Borneo, the submarine sighted columns of smoke from an enemy convoy which had been broken up by an attack by ano-her U. S. submarine the previous day. It was determined that the convoy was heading for Singapore at a slow rate of speed. The sub started pursuing it, with intentions of attacking before dawn. After a day and night chase, GURNARD recontacted the large convoy at 0634 the following day.

The underseas marauder made persistent and daring approaches on the Jap convoy, but only once was she able to secure a position for attack. On this occasion the torpedoes missed, due to a lucky maneuver by the enemy vessels. GURNARD was subjected to fire by the enemy's guns and to depth charge attack during this unfruitful 37-hour attack.

Clearing the attacking area, with the convoy well scattered and close to port, the sub headed for her patrol station off Tajong Datoe, with enemy depth charges echoing astern of her.

While patrolling west of Miri, Borneo, at 0612 on 2 November, GURNARD made contact with a five-ship enemy convoy and commenced her approach. After tracking the convoy for 18 hours, the sub hove into

— page 11 —
9 - (GURNARD)

position on two large tankers at 0048 on the 3rd, firing a three-torpedo spread at each. Two hits were scored on the second target and one on the first, and the sub sought the depths to avoid an onrushing escort. While deep, many breaking-up noises were heard from the targets, and upon coming to periscope depth it was determined that the second target had sunk and the first was badly damaged, but still underway.

GURNARD gave up the chase on the convoy as she had orders to proceed to a lifeguard station east of the Anambas Islands. After completing her lifesquad mission, the sub proceeded to her station and on the night of 8 November she made an unsuccessful attack on an enemy tanker.

Shortly thereafter, GURNARD steamed to the Java Sea and through the Lombok Strait, enroute to her home base. She moored at Fremantle, completing her war patrol on 17 November.

Following her refit, GURNARD steamed out of Fremantle on 11 December 1944, enroute to her Eightieth War Patrol in the areas east of Camranh Bay and north of Singapore in the South China Sea. During this patrol three submerged contacts with worthy targets were made but none could be closed for attack. Reconnaissance duty in connection with the Philippine invasion was performed by the submarine off Camranh Bay from 24 December to 9 January 1945, and area coverage during the patrol was excellent in spite of the prevailing poor visibility. GURNARD completed this patrol when she returned to Fremantle, Australia, on 1 February 1945.

Refit completed, GURNARD stood out of Fremantle on 10 March 1945, enroute to the South China Sea for her Ninth War Patrol, where she became part of a coordinated attack group along with the submarines USS HAMMERHEAD and USS BOARFISH.

This patrol was characterized by the scarcity of contacts, the lack of enemy air activity and the many native sailboats, which interfered with her mission. The only attack made was on 26 March, when two Japanese destroyer escorts were contacted in the bright moonlight. A night surface approach and attack was made, during which four torpedoes were fired, scoring no hits, due to heavy seas. GURNARD sank two floating mines and hit an uncharted pinnacle, which caused minor damage, while on this patrol. She proceeded to Pearl Harbor via Saipan (29-30 April), mooring at Pearl Harbor on 9 May 1945, thus ending her unfruitful war patrol.

Three days later, GURNARD set course for the West Coast, arriving at Mare Island, California on the 18th. At Mare Island she was subjected to a major overhaul. With repairs and alterations completed, on 11 August the sub set course for Pearl Harbor. While enroute the war's end was proclaimed, and on the 21st she churned in to Pearl Harbor.

Following voyage repairs, GURNARD proceeded to Midway, arriving there on the 26th, and departing on 1 September, enroute to the West Coast. The submarine, sailing in company with USS AGRIR and the submarines PIRANHA, LIONFISH, MORAY, DEVILFISH, HACKLEBACK, and ASPRO, arrived at the U. S. Naval Drydocks, Hunter's Point, San Francisco, California, on 11 September 1945. Here, the sub commenced pre-inactivation overhaul.

On 28 November 1945, her inactivation completed, GURNARD reported to the Mare Island Group of the Pacific Reserve Fleet.

USS GURNARD (SS 254) was awarded the Navy Unit Commendation for smashing 178,000 tons of Japanese shipping during her Second, Third, Fourth, and Fifth War Patrols. The citation reads:

"For outstanding heroism in action during her Second War Patrol in the Palau Islands, the Third in the South China Sea, the Fourth off the Southeast Coast of Honshu, and the Fifth in the Eastern Celebes Sea. Holding relentlessly to her missions in defiance of watchful aircraft patrols and surface escort vessels, the USS GURNARD daringly pierced the enemy's screen to strike at heavily protected convoys and combatant units in these restricted waters. She boldly closed range and sent her gunfire and torpedoes into one target after another despite continual hostile bombing and depth-charge attacks and sank 11 Japanese ships, including a destroyer, for a total of 71,500 tons; she damaged 10 additional vessels, one a 32,700 ton battleship and one a 17,000 ton aircraft carrier to score a total of 107,200 tons. Executing these hazardous patrols with the indomitable aggressive-ness, courage and skill characteristic of her gallant officers and men, the GURNARD achieved a record of heroism in combat in deepening with the highest traditions of the United States Naval Service."

U.S.S. GURNARD -- Report of First War Patrol.

Period from November 2, to November 15, 1942.

Area: Enroute New London to Base Two, Rosneath, Scotland.

Operation Order: Combat Force 25 Operation Order No. 375A-42.

1. This, the first war patrol of GURNARD, commenced at the end of the six weeks snakedown and training period following her commissioning.

Nov. 2. Tock departure seven miles east of Montauk Point proceeding in accordance with operation order.

Nov. 7, 1400(+3): Lat. 39-12N. Long. 48-45W. Sighted mast of ship bearing 012° T. distance about 6000 yards. Submerged and made approach. Target patrolling on course 003°T., speed about 3 knots. Appeared to be a converted yacht, with 3" gun forward, .50 caliber guns and ship's and depth charge racks aft. Closed range to 1400 yards; from silhouette, general appearance and frequency of echo ranging equipment in use by target concluded her to be a unit of Allied Forces. Discontinued attack and cleared area submerged. (Target similar to AG32 in CNI 54-R except had no after mast.)

Nov. 12, 1343(+2): Lat. 53-01W. Long. 23-35.6°. Sighted steamer bearing 350°. Submerged and made approach. Ship was not flying colors but had colors similar to British merchant colors painted across the front of her bridge. Painting was dirty and not easily distinguishable. At 900 yards ship appeared similar to British merchant ship HENZADA. Not being sure of the nationality of this ship and in the absence of positive evidence that she is an enemy ship discontinued attack and cleared the area submerged.

Nov. 14, 2330(-1): Lat. 56-36N. Long. 8-50W. Sighted a group of about five small vessels some lighted and some darkened. Searched area and determined these to be drift-net fishery men. Cleared area.

Nov. 15, 0700(-1): Made rendezvous with escort, ten miles, bearing 200° from Barra head Light and proceeded to Base Two.

2. Weather.

November 3 and 4. Overcast, Force 4 seas. Depth control at periscope depth difficult at less than four knots. Weather in general was fair, prevailing wind and seas were moderate and with few exceptions were northerly from NW to through NE.

   - None sighted.

10. Major defects experienced:
    (a) 0800 Nov. 5: Auxiliary Engine. While charging with auxiliary generator (270 KW-1200 RPM) a loud noise was heard in the auxiliary engine. Engine was stopped immedi- ately.

    Investigation revealed that an exhaust valve (Dwg. N9779, Ic 10) of number 4 cylinder had broken off its stem in the vicinity where valve taker joins stem. This loose valve damaged the three remaining exhaust valves, the fuel injector tip (Dwg. N9870, Ic 40) of this cylinder and cylinder head (Dwg. N9778, Ic 1). The cylinder liner and piston were scored.

1545 Nov. 9: On starting #3 engine the color of the exhaust was seen to be black. Investigation disclosed that the upper safety sneer pin (Dwg. 15101, fe 63) on the supersneer valve had broken. This pin was replaced with a spare and an ine placed in commission. The cause of the pin failure was not discovered.

: 1950 Nov. 10: Casualty to Main Drive Electrical Equipment.

Underway at 1 knots on generators 1, 2, 3 and 4, condition of seas 3 to 4 from astern.

Seas from astern washed through "ventional blind" structure around cutbox main induction valve and filled enclosure around induction pipes to level of opening of hull and engine induction valves. Water entered into engine room through engine and hull induction piping and the maneuvering room through hull induction piping. Personnel on water in the maneuvering room sensing trouble when they felt the vacuum created by engines as result of lack of air through the engine induction immediately stopped all engines and de-energized the main control cubicle. The alertness of the maneuvering room watch and their prompt action averted an electrical fire and possibly, very serious damage. Some water entered the maneuvering room through the hull induction before all circuits were completely de-energized and the following damage resulted from short circuits and electrical flashes caused by salt water.

(1) Salt water fell on the main terminal block on the forward end of starboard inboard main motor. This created a short circuit and arc which burned the backlite insulation between positive and negative terminals and melted some of the lead sheathing of conductors leading to the terminal block. Burned bakelite and fused lead were removed, insulators of asbestos were improvised and this motor was placed in commission.

— page 18 —
1. Water which dripped over the port side of the main control cubicle from leaky joints in ventilation piping caused grounds on leads to three meters. These grounds were removed by washing out wiring with fresh water and drying.

(2) Number two main generator field switch was sncrt circuited and burned beyond use. A new switch was manufactured from materials on board.

(4) Number four generator had a zero ground which was caused by grounded voltmeter leads in the after engine room. Also rield supply lead of number four generator from contactor #76 to lead #105A or the main cubicle burned cut. This lead was renewed and number four generator placed in comission.

Had this vessel been operating with the outboard hull induction supply valve closed, salt water would not have entered the maneuvering room. In the future the hull induction outboard valve will be kept closed while operating in more than moderate seas.

12. Sound conditions - Density layers.

No density layers were noted in any areas in which submerged operations were conducted.

13. Health and habitability.

Health and habitability were very good. The man received undetermined injuries to abdomen and back on November 15, when squeezed between two torpedo racks while handling torpedoes. He has been transferred to Base Two Dispensary for treatment.

14. Miles steamed surface and submerged.

Surface --- 3393
Submerged --- 124
Total --- 3517

15. Fuel oil expenditures.

49353 gallons.

17. What factors of endurance if any caused ending this patrol.

Operational Order.

18. Remarks.

(a) The water which entered the maneuvering room on November 10 came out of the two ventilation supply outlets in the forward end of the maneuvering room and through leaky flanges in the ventilation piping. The above outlets are so located that the water easily finds its way to the main motor terminal blocks which in its class of submarines are not contained in drip proof enclosures.

When operations permit it is planned to remake all flange joints of ventilation piping in the maneuvering room so that these joints will be water tight. It is also planned to eliminate and seal all supply outlets which are over electrical apparatus in the maneuvering room. New outlets will be taken from the supply piping in the extreme after end of the maneuvering room and arranged so that there is a minimum possibility of salt water reaching electrical apparatus.

(b) Since commissioning this vessel has experienced much trouble from salt accumulating in engine rooms as a result of salt water spray which enters through main engine induction openings. The inboard induction openings are near the engine control stations and engines governors and the accumulation of salt in this vicinity is especially bad. Also the H.O.R. engines have many exposed moveable controls which become encrusted with salt. The accumulation of salt was so great during this past patrol that more time was spent by engine room personnel cleaning salt from engines and instruments than was used in actual upkeep of machinery. It is felt that this entry of salt will eventually be the cause of engine derangements. This trouble is believed to be caused mainly by the "venetian blind" arrangements of plating around the main induction piping. Salt spray or water in striking the "venetian blinds" is broken into small particles. These particles of water are picked up by the air being drawn into the main induction piping and are carried into the engine rooms.

U.S.S. GURNARD -- Report of Second War Patrol.

Period from November 28, 1942 to December 27, 1942.

Area K505 - Bay of Biscay, Operation Order -- Comsubron FIFTY No. 3-42.

Operations since last patrol are as follows:

(a) Listening tests of machinery at Lock Goil Head.
(b) Degaussing calibration at slip, Base Two and over range at Helensburgh.
(c) Calibration of Radio Direction Finder Loop.

1. 1100 A November 28, 1942: Underway from Base Two, Rosneath, Scotland in company with escort HMS LAUDERDALE, proceeding via Clyde and Irish Sea to Bishop's Rock. 0830 November 29: HMS LAUDERDALE relieved by HMS WOLVERINE.

1330 Nov. 29: Fired 3", 20mm and .30 caliber guns for training.

1800 Nov. 29: Duty of escort completed, took departure Bishop's Rock bearing 0000T, distant 10 miles.

1835 Nov. 29: Lat 49-40, Long 6-42. Detected two aircraft on SD radar, range 9 miles, range decreased to 4.5 miles. Planes not in sight (evening twilight) submerged.

1940 Nov. 29: Surfaced, no indications of planes.

1000 Nov. 30: Examined timing and auxiliary drive gears all main engines. Found teeth broken off drive gear lower scavenger blower No. one engine, engine hours in use 440.

2000 Dec. 1: Received information of probable departure in near future of German tanker from El Ferrol and orders to patrol off that port. Proceeding on surface at best speed, heading for El Ferrol.

0846 Dec. 2: Lat 44-11N, Long 09-46W. Sighted unidentified aircraft, distant about 7 miles, bearing 350 relative (own course 1160T). Submerged to avoid detection (Plane contact #2).

0914 Dec 2: Plane not in sight, surfaced.

1203 Dec. 2: Lat 44-00N, Long 9-17W. Sighted seven unidentified planes in "V" formation, submerged. Planes were within two miles at time of diving but did not attack. Weather overcast, slight drizzle. (Plane contact #3).

1257 Dec. 2: Surfaced.

— page 26 —
1350 Dec. 2: Lat 43-53, Long 9-02. Detected air craft by radar, range 11 miles. When range decreased to 9 miles, submerged. (Plane contact #4).

: 1423 Dec. 2: Surfaced.

: 1605 Dec. 2: Made landfall on Mount Saint Lucia, bearing 1680T, distant about 25 miles.

: 1640 Dec. 2: Sighted about ten fishing trawlers. (See Paragraph 19).

: 1652 Dec. 2: Lat 43-39N, Long 8-24W. Submerged to avoid detection by fishing trawlers. Trawlers are coal burners, 40'-80' in length and usually work in pairs. About five larger trawlers, 150' in length working separately were also sighted in the same locality. Trawlers work in vicinity of 75 to 100 fathom bank within a fifteen mile radius of La Carunna. It is possible that some of these trawlers are engaged in work other than fishing. Their presence makes an undetected surface patrol in sight of El Ferrol impossible.

: 1900 Dec. 2: Surfaced. Stood in towards entrance to El Ferrol. Investigating navigational facilities and fishing activities near entrance. Nothing unusual noted.

: 2245 Dec. 2: Established surface patrol, across entrance to bay on line running between Islas Sisargas and Cabo Prior Lights. Weather overcast and misty.

: 0810 Dec. 3: Submerged, patrolling near entrance to El Ferrol on line between Cabo Priorino and Pt. Herminio.

: 1045 Dec. 3: Coastal cargo ship stood out from El Ferrol and proceeded to La Caruna. (Ship contact #1).

: 1100 Dec. 3: Small Spanish coastal oil barge, CAPRICHO, stood out of El Ferrol and proceeded on course 2500T (Ship contact #2).

: 1505 Dec. 3: Sighted large plane, similar to Sunderland, flying about three miles off coast. (Plane contact #5). From 30 to 50 fishing trawlers operate from La Caruna. They usually pass in or out of port during darkness early in morning or late in evening. Small dories line fish on Bajos de las Laxinas.

— page 27 —
1852 Dec. 3:  Surfaced near entrance to El Ferrol, visibility good. A night surface patrol near enough to entrance of El Ferrol to observe movements of all ships passing in or out of this part necessitates placing own ship in neutral waters close to entrance of El Ferrol. This position is so close to coast that lights from ashore make own silhouette easily visible to the fishing vessels passing in or out and also a good target for "U Boats". Therefore night surface patrols will be conducted 2 to 5 miles off Cabo Prior. From this position any ships passing near coast and North East of Ferrol should be seen.

Information as to whether or not German tanker had sailed from El Ferrol prior to our arrival off this port would be helpful in deciding where to hunt.

1920 Dec. 3:  Noted two green rockets being fired from signal tower on Mount Ventoso.

(Spanish markings used herein mean Spanish colors flying and painted on ships sides.)

2030 Dec. 3:  Established patrol 2 to 5 miles off Cabo Prior.

0215 Dec. 4:  Lat 43-37N, Long 08-32W. Sighted lighted merchant ship, Spanish markings. (Ship contact #3).

0331 Dec. 4:  Lat 43-38N, Long 08-32W. Sighted lighted merchant ship, Spanish markings. (Ship contact #4).

0350 Dec. 4:  Lat 43-34, Long 08-27. Sighted lighted merchant ship, Spanish markings. (Ship contact #5).

Shipping standing to South West Along coast passes Cabo Prior about four miles abeam.

0759 Dec. 4:  Submerged patrolling 3 to 5 miles off Cabo Priorino.

1450, Dec. 4:  Merchant ship, Spanish markings, stood out of La Coruna and headed along coast to South West. (Ship contact #6).

1810 Dec. 4:  Sighted two merchant ships off El Ferrol, Spanish markings. (Ship contacts #7 and #8).

1902 Dec. 4:  Surfaced, patrolling 2 to 5 miles off Cabo Prior.

2105 Dec. 4:  Lat 43-35, Long 08-24. Sighted lighted merchant ship, Spanish markings. (Ship contact #9).

— page 28 —
0220 Dec. 5: Lat 43-35N, Long 08-23W. Sighted lighted merchant ship, Spanish markings. (Ship contact #10).

: 0750 Dec. 5: Submerged.

: 0900 Dec. 5: Found four teeth broken on drive gear of upper scavenger blower of #3 main engine, engine hours in use 402. Engine hours at this time on other engines are #2 - 429, #4 - 297. Number 2 engine may be expected to fail any time from now on.

: The expected engine hours remaining on #4 engine and the use of the auxiliary engine are sufficient to return to Base 2 from patrol area, travelling about 185 miles per day, and diving during daylight. My decision is to reserve #4 engine for this run, remain on station until #2 engine fails and meanwhile replace the upper blower on #3 engine with the useable blower of #1 engine. Number 3 engine will then be held in reserve for an emergency.

: This gear trouble enforces a conservation of engine hours and leaves little reserve for surface operations. However in view of my orders to patrol submerged near Ferrol and because this area is comparatively small surface mobility is not primary.

: 1010 Dec. 5: Lat 43-33, Long 08-26. Sighted merchant ship, Spanish markings. (Ship contact #11).

: 1020 Dec. 5: Sighted merchant ship, Spanish markings. (Ship contact #12).

: 1330 Dec. 5: Merchant ship Monte Bizcargue, (1598 Ts) Spanish markings entered La Caruna from North East. (Ship contact #13).

: 1400 Dec. 5: Oil barge Capricho (about 200 Ts) stood out of La Caruna and entered El Ferrol. (Ship contact #14).

: 1410 Dec. 5: Lat 43-27N, Long 08-21W. Merchant ship, Villarreal de Alava (2538 Ts), Spanish markings, stood down coast from North East and entered La Caruna. (Ship contact #15).

: 1900 Dec. 5: Surfaced, visibility near El Ferrol hazy. Patrolling 3 to 5 miles off Cabo Prior during night.

: 0755 Dec. 6: Submerged.

: 0830 Dec. 6: Sighted merchant ship, about 1500 tons, similar in appearance to German ship Diana but with Spanish markings entering La Coruna from North East. Visibility too poor to read name (Ship contact #16).

: 1445 Dec. 7: Lat 43-37N, Long 08-22W. Sighted merchant ship Briquetas Zorrozas (4597 Ts), Spanish markings. (Ship contact #24). (This ship is over 2500 Ts, no notice of her movement has been received).

: 1901 Dec. 7: Surfaced, fog and haze during night.

: 0350 Dec. 8: Lat 43-36N, Long 08-21W. Sighted lighted merchant ship, Spanish markings. (Ship contact #25).

: 0755 Dec. 8: Submerged.

: 1500 Dec. 8: Lat 43-36N, Long 08-24W. Sighted merchant ship Antequera, (2810 Ts, movement report not received). (Ship contact #26).

— page 30 —

: 0755 Dec. 10: Submerged, weather overcast and rainy, visibility poor, Sea's condition 3.

: 1847 Dec. 10: Surfaced, overcast, squally weather, much lightning. Radio antennae glow during some periods of atmospheric electrical disturbances.

: 1915 Dec. 10: Lat 43-34N, Long 08-27W. Sighted unidentified lighted merchant ship. (Ship contact #30).

: 0300 Dec. 11: Lat 43-40N, Long 08-22W. Sighted merchant ship, Spanish markings. (Ship contact #31).

Have decided to shift night patrol farther off coast in vicinity of Cabo Ortegal for following reasons:

1. Presence of Cabo Prior may be known and have been reported by fishing vessels that aren't neutral.

2. Of about thirty ships sighted in this vicinity thus far, all show Spanish markings. Patrolling farther off coast, I might sight a "U" boat or a blockade runner that doesn't show Spanish markings.

: 0756 Dec. 11: Submerged, hazy, visibility poor.

: 0945 Dec. 11: Lat 43-45N, Long 08-15W. Sighted tanker, about 5000 tons, Spanish markings, unable to read name. (Ship contact #32). (At 2150 the 11th received FOS 1129 of the 11th reporting movement of Spanish tanker Campomanes, which was probably the above tanker.)

— page 31 —
1100 Dec. 11: Lat 43-45N, Long 08-07W. Sighted Spanish merchant ship Capital Se Garra, 2252 tons. (Ship contact #33).

: 1850 Dec. 11: Surfaced, seas condition 3 to 4. Patroling area 10 to 20 miles northeast of Point Estaca.

: 2300 Dec. 11: Lat 43-55N, Long 07-38W. Sighted lighted merchant ship, Spanish markings. (Ship contact #34).

: 0247 Dec. 12: Lat 44-02N, Long 07-30W. At 0247, 0325 and 0345 while patrolling on a southerly course an unidentified plane descended in glide to altitude about 300 feet and about 200 yards off quarter and turned searchlight on this vessel. Plane was challenged each time with aircraft recognition letter but did not reply. Notification of own planes operating in this area during tonight had been received.

It is not logical to assume a "U" boat would be on a southerly course in this vicinity. I believe this plane was friendly. If friendly, its action in illuminating GURNARD was stupid and uncalled for as while compromising the presence of this vessel it did not provide proof to the plane of a friendly or enemy status of the submarine. (Plane contact #8).

0750 Dec. 12: Submerged, weather overcast and squally, seas condition 3 to 4.

1837 Dec. 12: Surfaced, weather and seas still foul. Patroling area twenty miles north of Point Estaca.

Dec. 21:  Rainy, seas condition 3, range of periscope visibility very limited, remained on surface until conditions improved.

: 1105 Dec. 21:  Submerged.

: 1617 Dec. 21:  Weather and seas foul, surfaced.

1832 Dec. 23: Surfaced.

1142 Dec. 24: Arrived at rendezvous, maneuvering on various courses awaiting arrival of escort vessel.

1558 Dec. 25: Fell in astern of escort HMS ST ELSTAN and Netherlands submarine P-47 in order named. Proceeding to Falmouth at 10 knots to enable P-47 to land two sick men.

2302 Dec. 24: Anchored inside of boom at Falmouth.

0900 Dec. 25: Underway from Falmouth in company with escort, proceeding to Base Two. Have received warning to keep a careful lookout for floating mines in the Irish Sea.

0815 Dec. 26: Inspected gears of #4 main engine, found eight teeth broken on drive gear of upper scavenger blower. Engine hours in use 379.9.

0832 Dec. 26: Lat 52-43N, Long 04-58W. Passed two floating mines 300 to 500 yards abeam to port. Informed P.O.S. of their location, Morning twilight, visibility poor, did not attempt to shoot at mines.

1005 Dec. 26: Lat 53-01-30N, Long 04-56W. Sighted one floating mine.

1035 Dec. 26: Lat 53-07-30N, Long 04-55-30W. Sighted two floating mines, maneuvered to avoid. Fired 20mm and .30 caliber at mines in passing, no evidence of mines sinking.

1100 Dec. 26: Lat 53-12N, Long 04-55W. Sighted three floating mines ahead, maneuvered to avoid them. Fired at mines in passing. No evidence of mines sinking.

— page 34 —
1228 Dec. 26: Lat 53-30N, Long 04-58-30W. Sighted three floating mines ahead, maneuvered to avoid them. Fired at mines in passing, no evidence of mines sinking.

: 1414 Dec. 26: Lat 53-46N, Long 05-03W. Sighted floating mine 500 yards abeam to port.

: 1440 Dec. 26: Lat 53-54N, Long 04-51W. Sighted floating mine, maneuvered to pass well clear.

As twilight falls on the floating mines, I might add that this day of dodging them to say nothing of unsighted near misses during darkness has added a touch of color to a dull patrol.

0141 Dec. 27: Anchored in Rothesay Bay.

0846 Dec. 27: Underway.

1024 Dec. 27: Arrived Base Two.

10 miles north of Cabo Ferro, experienced a set of 3.1 knots, 0600T, over a period of twenty-four hours; wind force 5-6 from southwest, seas condition 6 from southwest.

4. NAVIGATIONAL AIDS
   - NAVIGATIONAL aids near El Ferrol are good, Characteristics of lights are as noted in light list except Cabo Prior and Point Herminio lights have dim flashes interspersed between bright flashes. These dim flashes occur during periods when lights are reported dark and could easily confuse strangers.

30 Nov. Inspected timing gears and auxiliary drive gears of all main engines. Found four teeth broken off at base for about 70% of gear width on the lower scavenger blower drive gear of number one engine. This engine has been in use for 440 hours since commissioning. Gears of other main engines appear normal.

5 Dec. Found four teeth broken off drive gear of upper scavenger blower number three main engine. Engine hours this engine since commissioning 402. Commenced removing upper blower and drive gear of number 1 engine to install this unit in place of upper blower of number three engine.

7 Dec. 1300 Completed installation of useable blower from Number one engine on number three engine.

26 Dec. Found eight teeth broken on drive gear of upper scavenger blower number four main engine. Engine hours in use 379.9; about 20 hours earlier than anticipated time of failure. This engine has not been run at less than 630 R.P.M. since passing 296.5 hours. (Hours on #4 engine when orders to operate at not less than 630 R.P.M. were received.)

11. Radio Reception.

(a) Radio reception under normal conditions was good. On the nights of December 10-11 and 15-16 while passing through electrical storms and rain, radio antennae glowed as if covered with luminous paint. At these times radio reception was very poor.

(b) Unable to receive HS broadcast on DQ Loop except at 40 feet, (periscope shears exposed). Connected SD radar antenna to low frequency receiver and was able to receive HS Broadcast at 53 feet providing seas were less than condition 4 and not breaking over antenna.

(c) Unable to receive a receipt for following GURNARD transmissions:
0010Z Dec 1 (4740 KCS) Message to FOS and CSS 50 concerning gear failure #1 engine.

1349Z Dec 2 (6480 KCS) Message to LGA requesting information on sailing of German tanker.

0241Z Dec 12 (3980 KCS) Message to plane, call sign LBA requesting that this vessel not be illuminated.

In each of the above cases own transmitter was tuned using a model TR-1 frequency meter. Transmitter tuning will be further checked with tender upon arrival in Clyde Area.

12. Sound Conditions and Density Layers.

(a) Lat 49-35N Noted unusual chirping noises. (Unable to Long 11-08W develop contact from these noises.) Sound is similar to school of fish noises heard in vicinity of Wake and Midway Islands.

(b) Dec. 8,1635 Noted odd whistling and water noises. Made Lat 43-36.4N visual observation along sound bearing of Long 8-23.8W this noise and noted a school of porpoise.

13. Health and Habitability.

Habitability was good. About 20% of the crew were bothered with slight head colds. Otherwise health in general was very good.

18. Remarks.

(a) Radar Operation:

(1) S.J. Radar - Considerable difficulty was experienced in maintaining this radar in a satisfactory operating condition.

(2) S.D. Radar - Performance of this radar was considered excellent. It is to be noted however that this type apparently will not indicate the presence of airplanes flying at altitudes of less than 600 feet irrespective of range.

(b) The necessity of conserving engine hours did not permit moving around the area and following ships sighted as much as I desired.

(c) Aside from providing excellent training and seasoning for officers and crew this patrol was uneventful. That no enemy ships were met is a disappointment to all on board.

U.S.S. GURNARD -- Report of Passage Base II, United Kingdom to New London, Conn. Period from January 25 to February 9, 1943. Operation Order - Commander Task Group 99.1 Operation Order 2-43.

PROLOGUE:

Arrived Base II, United Kingdom December 27, 1942 from War Patrol. Tender and ship's forces made a thorough inspection of gear trains of all main engines. December 29, a complete renewal of all main engine scavenger blower drive gears was found to be necessary. Repairs to three engines delayed until receipt of new gears from United States. January 16, 1943 received new blower drive gears and commenced installation. Repairs completed, underway for engine trials, training and calibration of degaussing coils on January 21 and 22.

1. 1100A January 25, 1943: Underway from Base II, United Kingdom in company with escort HMS CUTTY SARK, proceeding via Clyde and Irish Sea to Scilly Isles.

0515A January 26: Lat 52-31 N, Long 05-15 W. Passed floating mine, distant fifty yards abeam to port.

2100A January 26: Duty of escort completed, took departure with Round Island, Scilly Isles bearing 180°T, distant 7 miles.

1240Z January 27: Lat 49-54N, Long 09-56 W. While submerged, sighted British bomber, (plane contact #1).

2015Z January 27: Lat 49-53 N, Long 10-49 W. Sighted four steam fishing trawlers. Trawlers were about 120' long, were lighted and one had Spanish colors illuminated. Seas, condition 4, were too rough to permit going alongside for further investigation. These trawlers were similar to and were within fifty miles of a position in which trawlers with Spanish marking were seen by GURNARD on a previous patrol.

Night, January 28-29: Short but very rough seas from ahead have made it necessary to reduce speed to 7 knots on one engine. At this speed green seas frequently wash over bridge. Weather squally with hail.

0000M to 1345M January 30: Underway on one engine running into condition six to seven seas. Weather overcast, squally with hail.

10. Major defects experienced.

Scavenger blower #1 main engine.

The cause of this blower's failure cannot be determined until the blower has been completely disassembled. Facilities for doing this at sea are not available.

A visual examination through inspection plates indicates that the ends of the rotor rubbed against the end casing and subsequently one of the rotors moved along its axis about two inches thereby breaking the lobes and the forward end casing of the blower. There is some damage to the blower drive gear and its adjacent gear. Whether this derangement started with a failure of gears and subsequent blower damage or with a blower failure and then gear damage cannot be determined until the blower is disassembled. This failure will be fully covered in a derangement report.

11. Was radio reception complete and what were last consecutive serials sent and received.

(a) Except as covered below, NAA radio reception was normal and interference negligible. (All times are GMT). First NAA number received #248, missed #251, last NAA number received #459.

(b) Unable to hear NAA until 1420Z January 31, Lat. 47°-00' N., Long. 27°-43' W. (80 miles west of CHOP); guarded GBR until able to receive NAA. Noted interference as follows:

17. What factor of endurance if any caused ending this patrol; armament, fuel, fresh water, provisions, fatigue or personnel, or material failure.

Operation order.

As has been indicated by scavenger blower and gear troubles previous to the current operations and as again demonstrated by the current operations, the factor of endurance of this submarine is limited by the inherent weaknesses and consequent failures of the scavenger blowers and gears of the HOR main engines. Until such time as drastic changes to correct these weaknesses are made this vessel cannot be considered reliable beyond 300 engine hours of operation, subsequent in each case to a major overhaul of blowers and gears.

18. Remarks.

(a) Under conditions of seas and weather prevailing at this time of the year in the North Atlantic Ocean it is not practical to operate at speeds which will enable advancing an average of three hundred miles daily. To obtain the necessary power for 12.5 knots, under prevailing conditions, the use of three engines and the consumption of an abnormal amount of fuel is necessary. Also when running into condition four or greater seas at twelve knots the ship is subjected to considerable pounding and bridge personnel must be alert to avoid being washed overboard by green seas which break over the bridge.

(b) Trouble was again experienced with salt water and spray which entered engine rooms via the engine induction piping. Changes in the access to the outboard main induction valve to correct this trouble will be attempted.

— page 55 —
1. A brief synopsis of the scavenger blower and gear troubles of number one engine is submitted. This trouble is typical to the HOR model 99DA main engine.

(2) At 154 engine hours blower end clearance to casing was found to be less than when originally installed and was increased by factory representative.

(3) At 439.4 engine hours teeth broke off blower drive gear. Drive gears for both upper and lower scavenger blowers were renewed and blower clearance to end casing adjusted to design limits. This work was performed under the supervision of a factory representative.

(4) At 627.4 engine hours the failure of the upper scavenger blower as previously explained in this report occurred. This is 188 engine hours since renewal of gears and checking of clearances. During this period of 188 engine hours #1 engine was operated at not less than 630 RPM.

(5) It is the commanding officer's opinion that operating these engines at not less than 630 RPM is not the cure all for the blower and gear troubles experienced to date. It has been noted that when these engines are idled at 630 RPM, during maneuvering and warm up periods, that the engines vibrate excessively. Trouble has been experienced with leaks and failures to lubricating and fuel oil piping which have occurred as a result of this excessive vibration.

(6) There is no doubt that there is a critical torsional vibration in the gear trains of the HOR Model 99DA engine. It is believed that in addition to this torsional vibration some of the trouble encountered to date may be traced to the method and type of support of the blowers themselves on the engine framing. It is recommended that this be investigated as a source of the current troubles.

Subject: Patrol report - U.S.S. GURNARD, period January 25 to February 9, 1943.

1. Forwarded: This war patrol report covered a period in transit from the United Kingdom to New London, Connecticut. There were no contacts with the enemy.

2. The major defects of the main engines are listed in paragraph 10 and have been previously covered by separate correspondence.

3. It is noted that NAA was not satisfactorily received until Longitude 27°-43'W. was reached. This is in agreement with previous information, indicating that NAA reception by submarines is unreliable east of 30°W, although instances of satisfactory reception may be had as far east as 20°W. The sustained interference experienced January 31st and February 4th, while copying NAA (15.6 Kcs) caused by GBR (Radio Rugby 16 Kcs) and RXU the German Radio Station at St. Assise which operates alternatively on 15.22 and 15.66 Kcs is contributed to the small differential in frequency and the low signal strength of NAA at the limit of its coverage. In the future the use of the more powerful NSS on 18 Kcs while submarines are in transit from 20°-30°W. should be considered. The despatch missed (NAA #251) was not of interest to the GURNARD.

1. USS S. GURNARD (SS254) - Report of Second War Patrol - comments on.

7. The two ship convoy sighted on 2 July could never be closed but the bold bluff that almost brought success is noted and admired.

8. The prompt and efficient action taken after the surprise bombing on 6 July was also characteristic of an efficient organisation.

9. The fourth attack while resulting in the sinking of one AK and damage to another would have been even more successful had the commanding Officer not been handicapped by attempting a night attack without the SJ Radar. This instrument was a total failure throughout the entire patrol and the cause will be thoroughly investigated. The SD also seems to be far from up to standard.

10. The material condition of the GURNARD can be considered good and better than average in this Division as far as engineering difficulties are concerned. Rafts will be carried out by the GRIFFIN and all defectors noted can be corrected during the time necessary to thoroughly check the H.O.R. engines which, though still running, are the cause of grave suspicion. The health and morale of officers and men is excellent.

11. It is felt that the Commanding Officer, officers and men of the GURNARD are to be congratulated for one of the finest, most aggressive first patrols on record and that they be credited with the following damage to the enemy.

    #3 with small angle on bow and ship #4 was
    overtaking #3 about 1,100 yards to #3's port
    side in order to enter Toagel Lungui Passage
    first. Maneuvered to make bow tubes bear on #4
    and stern tubes on #3.

1230 I
    Lat 7-34.5N
    Long 134-26E
    Fired tubes 1, 2 and 3, range 800 yards at
    ship #4 (similar to TAKATIEO IARU), immediately put new set up in T.D.C. and fired
    tubes 7, 8 and 9, range 500 yards at ship #3
    (similar to AKAGI IARU) (attack #1). While
    firing stern tubes noted splashes around
    periscope from gun fire and DD near stern
    target headed our way. Ordered deep submergence and as we were going under noted smoke
    around stern of bow target whose screws had
    stopped and whose stern was settling. Four
    hits were heard in the boat, some people
    counted five. Sound counted three on the bow
    target and then one on the stern target, before torpedo noise was masked by many loud
    explosions, continuous crackling and high
    noise level which could be heard for several
    minutes over wide bearings.

1235 I
    Received first of 24 depth charges. Evaded
    by silent running, going deep under -15°
    temperature gradient, fish tailing. Rumbling
    noises and crackling still cover a wide band
    in direction of targets. There is no question
    in the commanding officer's mind that ship
    #4, bow target, sank within a very few minutes.

1305 I
    DD pinging became fainter, commenced planing
    up to periscope depth.

June 29 (cont't)
1310 I Received pattern of 4 depth charges while at 250 feet, went deep again.

1330 I Commenced reload. Air noises of blowing down tubes brought more depth charges, secured reload and took course to retire to northwest.

1435 I At periscope depth, one escort DD searching to eastward (Ship Contact #4), range 4,500 yards, retired to northwest and completed reload.

1745 I Same DD still searching, range 7,000 yards, bearing 075°T.

1941 I Surfaoed. Patrolled during night on 15 mile circle from Teagel Mungui Passage.

June 30
0320 I Sighted amber colored light which remained on for about 30 seconds. (To contact on SJ Radar). Visibility poor with rain and no moon. Headed into a rain squall.

0402 I Sighted light green colored light and again evaded. I believe these lights were momentarily exhibited by an A/S vessel as recognition signal (Ship Contacts #5 and #6). (Weather is too foul for ships to safely close and enter Teagel Mungui Passage.) Headed towards Teagel Mungui Passage. If the above lights were from an A/S vessel he may have expected us to head to sea and we wanted to be near Teagel Mungui Passage when visibility improves.

0445 I Submerged.

0755 I Commenced evading 3 A/S vessels near Teagel Mungui approaches. "SHOKKY", OTORI DD and ship contact #7, nick-named "CAGZY" who echo ranges on 17 KG and is much more proficient than "SHOKKY".

1020 I Sighted "Adam" seaplane patrolling to northward.

1355 I "CAGZY" close aboard acting as if he had a contact. Commenced evasion tactics and endeavored to reach position between him and coral reef in order that reef would give false background for echo.

Surfaced and proceeded to position for patrol during night on Toagel Ilungui Passage 15 mile circle. Patrolling close in to Toagel Ilungui Passage is desirable as from this position it is not probable that ships entering or leaving will be able to pass outside of torpedo range.

All three A/S vessels ("STOKEY", "CAGLY" and OTORI DD) searching the vicinity of Toagel Ilungui Passage

0630 I
Sighted DD larger and never looking than OTORI Class (Ship Contact #8). This DD and one of the A/S vessels were forcing us to retire to the northward (away from Toagel Ilungui Passage) in order to avoid detection.

0707 I
Commenced attack on DD. On second consideration abandoned idea of attack as everything pointed to a convoy movement. The actions of this DD in forcing us to use evasive tactics and retire to near the 5 mile circle might have spoiled an opportunity for an attack.

0755 I
Sighted second DD (Ship Contact #9) very close to Toagel Ilungui Passage.

0820 I
Sighted masts of four merchant ships near Toagel Ilungui Passage (Ship Contact #10); 2 large DD's, 2 OTORI DD's, 2 A/S vessels, milling around entrance and Adam (Plane Contact #8) circling overhead. Went to 250 feet and commenced approach at full speed running for about three miles towards position which convoy would probably pass. Sea again flat and oily calm.

0845 I
Coming up to periscope depth sound reported
propellers at 3 1/2° relative. At periscope
depth observed DD to be passing ahead, about
500 yards, four merchant ships in ragged
column, range about 2,200 yards, remaining
4/3 vessels sighted earlier on both bows and
quarters of convoy column.

0856 I
Fired tubes 1, 2 and 3 at DD, range about
800 using six second firing interval and 2 1/2°
spread between torpedoes. Shifted to largest
merchant ship, #3 in column, put new set up
in T, D, C. and fired tubes 4, 5 and 6, range
about 2,800 yards. (Attack #2) (Because the
commending officer did not make himself
fully clear to the control party a spread of
4° between torpedoes instead of a total spread
of 4° overall was used.) Sound tracked first
torpedo to hit destroyer at 34 seconds after
firing, and of second salvo timed hits at
1'50" and 2'16" after firing. After firing
tubes 4, 5 and 6 swung periscope to DD and
observed her to blow up forward of stack with
huge column of dense black smoke, swung back
to AK's and observed second hit from second
salvo to be about 75 feet from stern of and
on merchant ship, #4 in column, #4 had started
to overlap #3, about 400 yards on #3's far
side, scund called first hit of second salvo
while I was gloating over the destruction of
DD. (Believe NOT shot was hit on #3 ship,
the next torpedo spread 4° right passed
ahead and last torpedo spread 4° left was
seen to hit #4 ship.) By now three or four
small aerial bombs had exploded and a black
smoke float which plane had dropped was
burning profusely about fifty yards from our
periscope. Started deep, before going under
looked for destroyer, could see nothing but
a huge cloud of dense black smoke about 200'
high and 600' in breadth. Commenced evasion
tactics running towards center of convoy with
intentions of underrunning it and coming up
on far side, heard distant explosions and
rumbling noises similar to those of the 29th.
Recaived first depth charges five minutes and
thirty-five seconds after firing first
torpedo. Counted thirty-three depth charges
(scope close enough to rock conning tower.)
and four aerial bombs in next thirty minutes.

July 1 (cont'd)
Everything having been quiet for 12 minutes commenced reload forward. Had reloaded three torpedoes when at 51 minutes after firing torpedoes received 10 more depth charges. Secured reload and its attendant noises and abandoned idea of going up for look. A/S measures were much more severe and persistent than those of the 29th. Headed to westward running under a 20° temperature gradient, hearing echo ranging all around dial.

1103 I
Started up from deep submergence, pinging astern had become faint. While passing 120 feet heard four explosions, not close, sounded like bombs, remained at 120 feet but heard nothing until at 1112 I faint propeller noises on starboard bow, did not sound like a destroyer.

1122 I
Periscope depth. SURFRISE, incredible as it seems, sighted aircraft carrier with air escort (Ship Contact #11) range 3,600 yards, angle on bow 120° port, made fast sweep, no surface escorts sighted. Tubes 1, 2 and 4 (only forward tubes loaded) were made ready for a low power shot and went ahead at full speed swinging ship for zero gyro angle.

1125 I
Ready to fire low power shot; carrier has zigged radically to left, range is now about 1,800 yards, shifted torpedoes to high power.

1126 I
Fired tubes 2, 4 and 1 mean range about 1,800 yards track 112° port (Attack #3). First torpedo was premature at 24 seconds, sound tracked other two to hit at 127° and 140°. This being my first experience with a pre-mature my immediate reaction was that we were being depth charged by a surface escort which I had not sighted, so ordered deep submergence. Soon realized that this had been a premature caught depth near 80 feet and swung ship right to make stern tubes bear. Received three bombs while doing so.

1131 I
Quick set up and fired #8 tube; periscope depth, range about 3,000 yards, three more bombs while doing this. Noted carrier to be listed about 25°, was stopped or moving very slowly, had changed course away and was making much yellowish white smoke.

0848 I
Sighted plane (Flame Contact #11) coming out from direction of Falau to furnish the above ships air escort to Toagel Ilungu Passage, plane circled over ships. Ships now at approximately 70 miles o'cirele and about 12 miles from us. Submerged to avoid detection and want ahead at six knots for about thirty minutes to determine remote possibility of attack. Target smoke and plane drawing away.

— page 70 —
1020 I
Since can't catch AK's submerged, since our presence in vicinity is known and since plane is in sight where he can't surprise us, surfaced and commenced end around run. Distance and time from Falau will not enable us to draw out to flank far enough to avoid being sighted by plane and still intercept ships before they reach Falau. There is a remote possibility that plane might not see us or that being on the surface he will be bluffed into thinking we are friendly.

Currents off Toagel Passage are strong and predominantly to northeast. Sets from 340° to 090° with drifts of 1/4 to 1 knot were experienced in the area 5 to 50 miles northwest of the passage. The currents in the immediate vicinity of Toagel Passage are predominantly northeasterly but vary with the state of the tide. The contour of the reef apparently affects the direction of the current. At times when close to the passage and when deep considerable difficulty was experienced by the helmsman in maintaining course. At one time it was necessary to carry 15° rudder to maintain course at 200', speed 3 knots.

An analysis of previous patrols and our own experience indicates that convoy movements through Toagel Passage are normally made within one hour of slack water.

(2) NAVIGATIONAL AIDS

Toagel Passage is not lighted.

There is a white triangular marker on the western edge of the reef at the south side of Toagel Passage. This marker is very predominant and is helpful when piloting close to the passage approaches. Approximate position of marker is Lat. 7-32.3 N., Long. 134-25.0 E.

There is a black buoy located on the northwestern edge of the reef, approximate position - Lat. 7-32.0 N., Long. 134-24.5 E.

Hill 790 does not cut in well. It is considered to be approximately one mile farther south than charted. This hill is not prominent but can be distinguished by a small greenish colored square sited or house on its summit.

(I) MINES

No mines laid or sighted. No minesweeping operations observed.

(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS.

Anti-submarine measures were conducted during all daylight hours within the fifteen mile circle of Toagel Hungui Passage. At least one and usually two converted tankers, about 600 tons, would come out of the passage each morning at daybreak and commence a listening patrol running at various speeds from stop to eight knots. They would steer various courses in order to cover the inner five mile sector very thoroughly and then would fan out along probable convoy routes. On days when these vessels were not on hand small vessels similar to converted yachts carried on the same operations.

On June 30, day following first attack, a small destroyer was on hand using echo ranging very effectively. On July 1, (day on which convoy sailed) in addition to the two converted tankers four destroyers were on hand. They used echo ranging (about 17 kt) and covered the five mile sector of Toagel Hungui Passage very thoroughly. We were forced to use evasive tactics at this time as well as during afternoon of June 30. Destroyer class searched for us on July 2 and 6 when our presence had been determined by a plane.

The water off Toagel Hungui Passage is extremely clear and unusually calm. Our experience is that a plane quickly sights a submarine at periscope depth. Pilots work with A/S vessels. A/S vessels seem to coach plane to general vicinity of submarine and then when submarine comes from deep to periscope depth for a look plane drops bombs. This happened to us twice on July 6. Also, if a plane sights submarine and no A/S vessels are around, A/S vessels soon arrive. During the attack on convoy, July 1, in addition to dropping bombs planes dropped a smoke float in our position. The quick spotting of the periscope and torpedo wakes by plane diving attacks prevented us from watching the results of our hits. Airplanes do good A/S work near Palau and are a definite hazard which must be treated with caution.

All ships soon within 50 miles of Palau had an air escort; as convoys approach Palau additional surface escorts go out to join them so that they are well covered as they approach Toagel Hungui Passage. It is not known that two destroyers based, they were seen on one occasion to head for Kossol Passage at Sunset.

A ship of about 1,900 tons similar to photo on page 255, ONI 206 J but with forward must replaced by gun, believed to be a "Q" ship with escorts was seen on July 6, near Palau.

— page 91 —
U.S.S. GURNAID (SS254) - Report of Second War Patrol.

Depth charges were dropped singly and in patterns. The first ones dropped after an attack are usually patterns in the vicinity of the submarines last known position.

The search by A/S vessels after an attack is not particularly persistent. With the temperature gradient existing near Palau echo ranging is apparently not very effective. A/S vessels alternately listen and echo range. At the end of about an hour after an attack they seem to have lost the scent completely and soon thereafter evasion at periscope depth becomes possible.

Evasive tactics consisted of going deep under temperature gradient running at full speed for about five minutes after each attack, making a turn during the run and then running at 1/3 or 2/3 speed swinging about 200 alternately to right and left while heading in the general direction of the convoy track or foreign noises in the vicinity.

(K) MAJOR DEFECTS AND DAMAGE.

ENGINEERING:

On June 13 while charging battery with auxiliary engine, operating at 1100 RPM, 250 KP, a loud noise was heard in #5 unit of this engine.

Investigation revealed that exhaust valves of #5 cylinder had either stuck open or been badly worn. The piston on its upper stroke. Three of the four exhaust valves were bent. The fourth valve had broken off and 'arced between the top of the piston and cylinder head. The piston, piston and unit injector were damaged beyond use.

Repairs were made by installing the following new parts:

(1) Cylinder head assembly  Tag N 6770 on 1,2,3,4
    H 6732 on 74,75,77
    N 6733 on 131,137
    H 57's on 25
(2) Piston, complete  Tag N 977' on 1-5 inol
    H 57's on 2
(3) Exhaust valves (4)  Tag N 577' on 10
(4) Exhaust valve stem (4)  Tag N 779' on 17
(5) Injector assembly, complete  Tag N 6070 on A

On June 23 a similar casualty as above occurred on #2 unit of auxiliary engine. The damage to materials was not as extensive as that

— page 92 —
1. U.S.S. GURNARD (SS254) - Report of Second War Patrol.

- of June 13, reports required only four net exhaust valves.

This is the third of a similar type casualty which has occurred since commissioning of this vessel, the first having occurred in November 1942.

After the casualty in November inspection revealed that "Valve Cap Shim" (G.M.C. Dwg N9779 po 15) was missing on all units. At this time brass shims (steel shims were not available) were installed to equalize the heights of all valve stem caps and to give a valve stem cap clearance of 0.018". After installing these shims there was no exhaust valve trouble for the next 500 engine hours.

In March 1943 the exhaust valve casualty was discussed with the machinery contractor representative for this engine. He advised that the above shims were not necessary and recommended their removal. Owing to other more urgent work those shims were not removed until about June 7, 1943. The casualties of June 13, and 23 occurred 10 and 36 engine hours respectively after shims were removed.

Brass shims have again been installed on all units.

Main Engine #2.

It was necessary to secure #2 engine when a loud knocking noise was heard in it while tracking target during darkness July 11. Examination of #1 unit of #2 engine revealed that two piston rings had broken (hours in use 1477). Some pieces of the broken rings had fouled the supercharger valve and had found their way between the piston and upper head. Because the piston was fouled by these pieces on its upward stroke the piston rod was bent. A resulting decrease in lower head clearance caused damage to both lower injectors.

The following major parts were removed:

1. piston and rod assembly
   - Dwg N 5031, pc. 1-7,9,11-18
   - Dwg N 5027, pc. 8,10,13
2. fuel nozzle and housing assembly, lower right hand
   - Dwg N 5433, pc 1-16
   - Dwg N 5123, pc 1-9, 112

   - Dwg N 5433, pc 2-17
   - Dwg N 5123, pc 1-9, 12
   - Dwg N 5285, pc 47

   - Dwg N 5032, po 18
5. piston rings, left hand
   - Dwg N 5032, po 17

U.S.S. GURNARD (SS254) - Report of Second War Patrol.

On July 23 #2 engine was secured to investigate a loud knocking noise in it. Investigation revealed that 2 piston rings of #5 unit had broken. A piece of a broken ring had wedged under supercharger valve Dvg, N 5099, pc 4 and 39 resulting in the shearing of safety shear pin Dvg. N 5101, pc 63 and the supercharger valve was dented to an extent tint it struck and jammed in its housing. Repairs to supercharger valve were made by smoothing out dent with a portable grinder.

Main Engines #4.

Cylinder lubricator of #1 unit failed when bushing Dvg. N 5364, pc 13 broke, apparently from metal fatigue. Repairs were made by installing a new cylinder lubricator, Dvg. N 5362.

Main Engines - General.

Failures of lubricating oil lines have necessitated taking main engines off propulsion about ten times in order to make repairs.

There were nine different times when an engine exhaust valve failed to close on diving, each time engine was flooded. The sprays installed prior to departure on patrol in Po 12, BuDvg. SS212-S4I-901 Alt 4 apparently have not solved the cause of failure to close of exhaust valves.

One third stage and two fourth stage coolers of C&R air compressors developed leaks. These were repaired by silver soldering. These coolers require renewal during refit.

BEDFORD, MAINE

On July 6, a bombing attack caused temporary loss of power on bow planes when contacts 100 and 100A of rigging interlock switch BuShips Drung 389203, E.B. PI 2062-89, were jarred open.

ORDNANCE MATERIAL

On June 16 during fire control drill the left drive relay, Ord No. 212605, piece No. 2, Ord. Sketch No. 91502 of the Mark 1, Mod 2 control unit of the after torpedo room gyro setting indicator regulator burned out. Gyro spindles were engaged. The load was normal and there was no apparent reason for failure other than possible faulty clearance adjustment of the relay contacts. Contacts had fused at one small point. Replaced relay with spare.

NAVIGATION MATERIAL

The Pitometer Log is not rugged enough to endure frequent dives.

to deep submersion. Sleeve for shaft seal, (Dwg 6-1B AHI Part 46 Instruction Book #36FF) often leaks permitting water from outside bellows to pass via bearings into the control unit. Repairs and adjustments during the patrol have required the renewal of several small parts and over 45 man hours of work by an electrician.

(L) RADIO

On July 1 while attempting to transmit GURNARD's 011543 a small electrical fire broke out in the K-4 power relay of the TEL-6 transmitter. Investigation revealed that contacts at this relay had become loosened, probably aggravated by depth charging. The arcing across loose contacts had burned the relay to such an extent that a complete rebuilding of it was necessary. Transmitter was out of commission for about eight hours.

Radio reception was satisfactory.

Last serial received was 87 (261021 July 143).

Last message sent was 200920 July 143.

In the locality of this patrol, Palau Islands, incoming traffic on the NPM 1100 or 1300 GGT schedules was received with no difficulty. At 1500 GGT interference becomes noticeable and signal strength starts to decrease, at 1800 GGT NPM FIX is not readable. At 2100 GGT NPM is again readable.

In transmitting outgoing messages it was found that shore stations were reluctant to answer the general call (NQO) but readily answer their own call. NZ, Noumea, New Caledonia was worked without difficulty on 4235 KES at about 1200 GGT. The enemy attempted to jam this frequency but was unsuccessful.

(M) RADAR

The following repairs and adjustments to the SJ Radar have been necessary since departure from Pearl Harbor.

1. On June 16, at Midway, the RF tuners and converter unit were tuned to give maximum echoes, with good results. Shortly after leaving Midway, the echo amplitude decreased considerably. Since the receiver "grass", the magnetron current, and the RF output at the kidney joint looked normal, a further check was made on the RF tuners, with-out results.

2. During the adjustments at Midway, the output voltage of regular-

— page 96 —
7. On July 3 the range unit began to out out intermittently. Wave form tests showed the trouble to be in the crystal tank; and resistance tots showed the lead of the sending crystal to be intermittently shorting to ground. Some work with the crystal lead apparently corroborated the trouble, and the range unit functioned one more night, then failed again. The crystal was removed from its mounting in the range unit; and the short was found to be inside the watertight crystal assembly. Since crystals are not carried as equipment spares, the range unit had to be scoured. A paper ranee scale for use with the expanded sweep, on the basis of 30,000 yards for the full width of the scope, was attached to the screen of the cathode ray tube.

8. On the night of July 9, one of the fuses, F3 or F4, in the blower motor circuit, would burn out after the radar had been in operation about 30 minutes. This happened three times, operation appearing normal each time after the fuse was replaced and the set turned on. The suction fan motor was found to have both the armature and field shorted; and the fuse would blow out when the transmitter became warm enough to close the thermocstat switch to this motor. The motor was replaced.

9. The 00-AMS (Radar motor-generator) set has not operated satisfactorily since installation. Operation is normal for about three or four hours, then the voltage and frequency drop, indicating improper operation of the speed control. Overheating is probably the cause of this. The SJ Radar was operated not of the time on the IC motor-generator system.

REMARKS:
SJ Radar was installed on this vessel during September 1942. Its operation for a few months thereafter was considered good though not reliable.

During the six weeks of commissioning training constant attention to the SJ Radar by Radar specialists was required in order to obtain ranges as high as 5,000 yards. The commanding Officer assumed this to be an optimum range. Upon arrival in European waters the SJ was in-operative after 17 days at sea. Repairs were made by a radar specialist prior to departure on a European patrol. While on patrol SJ failed again and on return to a European Base the services of specialists were necessary to place it in operation. Upon return to the East Coast U.S. SJ was again not operating.

While awaiting engine repairs, March and April 1943, the SJ was removed from the vessel and given an overhaul to the Radar Repair Shop, Submarine Base, New London.

— page 97 —
U.S.S. GURNARD (SS254) - Report of Second War Patrol.

During this vessel's passage from New London to Cocos Sola, April 28 to May 6, 1943, the SJ performed better than it had at any time since its original installation, pipes being obtained on ships at ranges up to 12,000 yards. The performance of the SJ became poor after this and the SJ was in-operative on arrival at Pearl Harbor about May 26. Total reliable operation had been less than three weeks.

While at Pearl Harbor factory representative, tender, Submarine Base, Pearl Harbor personnel and a Radar Officer who reported aboard while we were at Pearl sent several days checking the SJ. On departure for patrol June 12 the SJ Radar was operating to an extent that ranges on destroyer could be obtained by an expert operator from 6,000 to 9,000 yards. Upon arrival at Midway, SJ was operating very poorly.

While at Pearl the commanding officer discussed SJ Radar Performance with commanding officers of other submarines. Judging from the performance of other SJ Radars ranges of 5,000 yards are not good performance, the normal pip on a destroyer being 10,000 yards and pips on merchant ships being from 15,000 to 20,000 yards.

The commanding officer, while not belittling SJ Radar, as its use was sorely missed on the night attack of July 11, and not liking to complain about his tools, feels that the SJ Radar set installed aboard this vessel is a "liberty" and except for a few days during the passage from New London to Cocos Solo has never been up to average in performance. Without a good SJ Radar it will be difficult for this vessel to reach the high standard of night combat efficiency prevailing in other submarines of this force.

Operation of the SD-2 Radar appears to be satisfactory though it did not always indicate airplanes at the times planes were sighted when it was in operation.

(N) SOUND GEAR AND SOUND CONDITIONS.

Sound conditions most of Palau were fair to poor, targets were usually not heard until within 3,000 yards.

The changes in water temperature, as much as -20°F from surface to 300 feet, plus noise level and false echoes obtained by A/S vessels when we were close to coral reefs made it possible to approach Toagel Mungui Passage fairly close in spite of the practically continuous presence of A/S vessels.

Both Sound head training motors were flooded from an excessive amount of water which was flooded into torpedo room bilges during

— page 98 —
1. U.S.S. GURARD (SS254) - Report of Second War Patrol.

firing and reloads of July 1. Motors were disassembled, parts washed with fresh water, carbon tetrachloride and boiled to restore the insulation readings. Insulation of field coils remained low and failed after a few hours of operation. Continued use of sound gear by hand training of sound heads using one receiver in torpedo room and telephone communications for receivers in conning tower.

(O) DENSITY LAYERS

Thoroe is a deadlocked tomoroture gradient within 15 miles of Toggel Mungui Passago. The tomoroture curve breaks sharply to the left (negative) at depths from 150 feet to 250 feet. The tomoroture gradient near those depths was never less than -5° and at one time was as much as -20° below the surface tomoroture.

Those density layers usually made it necessary to FLOOD in about 6,000 pounds when going from periscope depth to 300 feet.

(P) HEALTH, FOOD AND HABITABILITY

1. Health was in general excellent. One gase of propellant burst-tis (water on the knee) and one case of boils were the only admissions to the sick list from the crew. The Engineer Officer was confined to his bunk for two days and will require a thorough examination by the tender or base doctor on arrival as a result of the contusions (abdomen and chest) and lacerations received from being struck by storm planes hand power operating handle while attempting to operate the storm planes by hand. Power was out in at the panel aft, by-passing storm plane pilot circuit, thoroby spinning the hand wheel which struck and injured him.

2. Food was varied and good. A larger and more varied supply of frozen vegetables than were available prior to departure would be a decided improvement to diet.

3. Habitability was in general good. Carbon dioxide content on the long all day dives was kept below 2% by using one can of CO2 absorbant for each all day dives. While patrolling in the close vicinity of A/S vessels the boat was rigged for silent running including the stopping of air conditioning plant, supply and exhaust blowers, fans, etc. in order to avoid detection. The ship at these times became hot and humid. Otherwise the ship was comfortable at all times despite the tropical summer weather.

3. Nails were served at normal times. Salt tablets and vitamin tablets were taken by all hands.

4. The record playing machine was very much in use and much appreciated by all hands.

U.S.S. GURNAUD (SS254) - Report of Second War Patrol.

(Q) PERSONNEL:

The commanding Officer is happy and proud to report that the performance of duty of all hands on this patrol, the first one in which GURNAUD has been able to take offensive action, left nothing to be disired and was in keeping with the highest traditions of the Naval Service. The response to duty of the crew during the whole patrol and especially during the hours of action on July 1 and the attack by anti-submarine vessel and plane on July 6 was excellent and reflects great credit upon the officers and leading petty officers whose efforts are responsible for the present state of training.

The Executive Officer of this vessel, Lieutenant R. E. M. Ward, by his tireless efforts in training the fire control party anrotute to station and by his fine coordination of the control party during action is greatly responsible for the results of this patrol. His coolness and counsel when under pressure were a tremendous support to the commanding officer.

The splendid manner in which the diving officer, Lieutenant R. C. Giffin, Jr., maintained depth control of the ship during the action, relays, and evasive operations covering a period of more than six hours on July 1 is especially commendable.

The intelligent and highly proficient operation of the Torpedo Data Computer by Lieutenant G. S. Simmons, III, made it possible to successfully fire on two separate targets within one minute on both June 29 and July 1.

ENCLOSURE (A)

1. The commanding officer is aware of the fact that two overlapping ships forming an elongated target are not the same as one long target. The two occurrences of such targets and hits on both ships with the same salvo on this patrol were morally coincidences.

2. Black paint is not considered the best color for prevention of detection by aircraft when operating submerged in clear blue waters similar to those around Palau.

3. Observations of torpedo explosions on this patrol were not sufficient to form a comparison of the relative destructive effects of TNT and Torpex warheads.

Subject: U.S.S. GURNARD (SS254) - Report of Second War Patrol - comments on.

1. The Second War Patrol of the GURNARD which was her first in the Pacific area and covered a period of 44 days of which only 15 were spent in the area assigned in contact with the enemy. The expeditious expenditure of all torpedoes was the limiting factor.

2. The customary expression that the area was well covered does not fit this case as the GURNARD stuck her head in the bottle rock and stopped traffic at its source. This patrol offers an excellent example of what can be accomplished by taking the fight into the enemy's back yard.

3. Due to the intense and numerous antisubmarine activities always present on the GURNARD's attacks, very little arthedox tracking and plotting could be carried out. In one attack only two poriscope observa-tions could be obtained. On another only three bofore it was necessary to fire. Yet despite the necessity of practically shooting on the fly a 58.3 percentage of hits was obtained.

4. On the first attack the GURNARD placed herself in beautiful position where the bore tubes bore on one target (sunk) and stern tubes on another (damaged). She then used a 150' temporaturo gradient to advantage in evading.

5. The second attack was also characterized by bold aggressive action where little opportunity was available to do anything but look and shoot, yet one fine nor DD was sunk and the AKE at least damaged. Prompt and severe antisubmarines were immediately forthcoming and again use use was made of a good temperature gradient.

6. The Commanding Officer seems to think that it was incredible luck that he should see an aircraft carrier for his third attack. The Division Commander disagrees since if a submarine practically sits in the entrance of an active enemy harbor, numerous worthwhile contacts are not the result of luck but the just reward for guts. It is noted that despite bombing the GURNARD swung and delivered another salvo at this carrier and it is only regrottted that nor torpedoes wore not immediately available. From the evidance it is felt that this target definitely sank but due to its high value (evidently nor CV of 17,000 to 20,000 tons) it is with regret that until further chock can be made only damage can be claimed.

1. It is felt that the remarks in the endorsement made by the Commander Submarine Division 121 fully cover the subject report and that damage to the enemy should be credited as requested therein. The Squadron Commander wishes to stress the point that he, too, feels that the CV sank and that all available sources of information should be ferreted out so that sinking can be credited. It is regretted that positive proof is not now at hand.

2. It is with the greatest of pleasure that the Commander Submarine Squadron TWELVE congratulates the Commanding Officer, Officers, and Crew of the GURNAD for an epoch making patrol in submarine warfare. The patrol was conducted with a fighting and determined spirit and an aggressiveness that left nothing to be desired.

7. The two ship convoy sighted on 2 July could never be closed but the bold bluff that almost brought success is noted and admired.

8. The prompt and efficient action taken after the surprise bombing on 6 July was also characteristic of an efficient organization.

9. The fourth attack while resulting in the sinking of one AK and damage to another would have been even more successful had the commanding Officer not been handicapped by attempting a night attack without the SF Radar. This instrument was a total failure throughout the entire patrol and the cause will be thoroughly investigated. The SD also seems to be far from up to standard.

10. The material condition of the GUNNARD can be considered good and better than average in this Division as far as engineering difficulties are concerned. Rofit will be carried out by the GRIFFIN and all defects noted can be corrected during the time necessary to thoroughly check the H.O.R. engines which, though still running, are the cause of grave suspicion. The health and morale of officers and men is excellent.

11. It is felt that the Commanding Officer, officers and men of the GUNNARD are to be congratulated for one of the finest, most aggressive first patrols on record and that they be credited with the following damage to the enemy.

1. The second war patrol of the GURNARD was its first made in the Pacific Ocean area. This patrol was outstanding in aggression, strategic planning, successful torpedo attacks and results.

2. The GURNARD carried out the patrol in an area unusually strong in enemy anti-submarine activities. Coupled with this hazard is the fact that this area is difficult because of the many fleet, calm days which make the enemy air activity particularly efficient. In spite of severe depth charging and bombing the GURNARD continuously and tenaciously hung on to its targets and pushed home its attacks successfully. It is of note that on one occasion when a close bombing forced the GURNARD partially to the surface, an excellent recovery and subsequent deep submergence avoided possible serious damage.

3. By skillful use of the bathymetrograph, combined with audacious planning, the GURNARD found that the waters close to Toegal Mungui Pass could be used to petrol in in spite of heavy anti-submarine activity. By getting in close the GURNARD used reef noises to outwit the enemy and after attacks used density layers to evade. This is an excellent example of proper use of modern equipment.

4. The attack on the aircraft carrier within two hours of an attack on a large convoy, followed by severe depth charging, is considered outstanding. All attacks were well carried out in spite of numerous surface and air escorts.

5. This patrol is considered successful for Combat Insignia award.

6. The Commander Submarine Force, Pacific Fleet, congratulates the Commanding Officer, officers, and crew for this particularly aggressive and successful patrol. The GURNARD is credited with having inflicted the following damage to the enemy:

U.S.S. GURNARD (SS254) - Report of Third War Patrol.

at this early stage of the patrol there is too little to gain and too much to lose in a gun engagement with such a target. It is noted that this sampan patrol is about 180 miles from Marcus Island. (Ship Contact #1)

Sighted smoke puff on horizon bearing 230° T. Commenced maneuvering to reach p osition 12 miles on approximate course 295° T (Ship contact #2). Sighted one mast of second ship's astern of smoke.

Sighted plane heading towards us from direction of target. (Plane contact #2).

Submerged to 140 feet.

At periscope depth, plane in sight flying ahead of target.

Watched plane fly out of sight to southwest. Surfaced and headed away from target track for about 4 miles to avoid detection by plane and then resumed eno around. Smoke not in sight.

Flame not in sight. In p osition ahead of smoke. Sighted unidentified submarine on surface. (Ship contact #3). Smoke bears 130° T, submarine 179° T. Submerged.

At range 8000 yards to smoking ship, noted a destroyer to be about 1000 yards astern of her. (Ship contact #4). Target is a small merchant ship. The situation appears suspicious. The smoking target may be a "Q" ship or en ordinary merchant ship; if the latter, why is the destroyer astern? They both may be escorts enroute to join a convoy coming up from the Marianas. At range 6000 yards heard pinging from two sources in direction of target.

Range 3400 yards, target, similar to SYOHO LARU, is a two nested merchant ship with a high thin stack, high bridge, gun mounts fore and aft, appears to be a "Q" ship of about 2000 tons. She zigged and presented small angle on bow. Went to 110 feet in order to increase speed and open distance to track. Decided target of this size not worth torpedoes so early in patrol, will continue approach on DD and fire on her if she is larger than a Chidore Class.

1651 K
Heard first of 42 depth charges which were dropped singly and in patterns of four until 1720. Being at 110 feet went deep below a (-) 15° temperature gradient and took evasive measures. No charges took close though they caused the main induction to become flooded thus making depth control difficult. (See paragraph (X)). Do not think we were sighted; perhaps target had a sound contact.

1755 K
Evading at periscope depth. "Q" ship and DD pinging and carrying on a systematic search on various courses about 5000 yards astern. Depth charges at 1805 and 1827.

1950 K
Lat 26-10 N Long 144-38
Total darkness, surfaced and cleared vicinity. While doing so noticed A/3 ships blinking white lights astern.

The plane and destroyer helped to make this target appear worth while during the early stages of the approach. After expanding over 1500 gallons of fuel and more than ten hours only to be "sucked" into conducting a sound run for a "Q" ship I am anything but pleased with the day's work.

Sighted smoke bearing 180° T and commenced approach. At 1232 made out masts of three ships (Ship contact #9) and vessel similar to ship contact #7. Angle on bow is about 60°.

: 1314 H
Sighted single unescorted AK about 6400 tons (Ship contact #10). As we are near the track of this ship and as the possibility of closing the convoy track near enough for an attack is remote, shifted to single AK target.

: 1336 H
Fired torpedo tubes 3, 4, 5 and 6 at 8 second intervals, range 1650 yards, mean track of #3 and #4 - 50° stbd., of #5 and #6 - 73° stbd., spread angles 1° right, 1° left, 4° right, 4° left, gyro angles between 355° and 003°. (TRIPEDOS MADE HEAVY BLUE SHORE HIGH AT ONE TIME COMPLETELY OBLITERATED PART OF THE TARGET). I purposely fired the 50° track having been informed that failure of warheads to explode could be expected on near 90° tracks. I had expected target to zig towards torpedoes to avoid. However target turned left (away) after #4 had been fired and presented a larger track. Sound heard two thuds about the time torpedoes should have reached target. Simultaneous with one thud I observed a column of water about 40 feet long to blow up above the deck height of the target at a point half way between her stack and stern. Shortly thereafter several people on the target ran over to where the water column had risen and looked over the side of the ship. I don't believe the warheads detonated (no underwater explosions were heard), the water column may have been from the rupture of one air flask. (The movements of the target resulted in anything but a sharp hitting-angle for torpedoes).

: 1339 H
Fired tubes #1 and #2 at 15 second intervals, range 1500 yards, track angles 152° stbd., gyro angles 018° and 017° using a spread of 1° left and 1° right. There is no evidence that either of these hit.

Target zig zagging on base course about 230° T. Decided to conduct submerged approach as visibility in moonlight is fair and it is about 3 to 4 hours before visibility dark enough for a surface attack can be expected.

Oct. 10, 1943

Through periscope observed two hits on target. Neither of the explosions were as terrific as those of the early morning of 8 Oct. The noise was less, flash was less, and the amount of water blown up was less. Target swung around a circle, dropped 3 or 4 depth charges, fired her stern gun, stopped for awhile and then headed to the east.

0400 H
Firetubes 1, 2 and 3, torpedoes in low power, range about 3000 yards, average track 106 F, gyro 359° (Attack #5). The third torpedo fired was a premature about 400 yards ahead of us. This torpedo had been activated on board ship. A weak explosion was heard; the flash and disturbance of water at target was hardly noticeable. Very soon after the premature, fired tubes 6, 5 and 4, range 2600 yards, torpedoes in low power, average track 112 F, gyro 357° (Attack #5a). The premature advertised our firing thus target had over two minutes to maneuver before the three torpedoes of the second salvo reached her track. Target swung away from us, she dropped a few depth charges and fired her stern gun aimlessly. We trailed, her speed had not been reduced, she still headed in the general direction of land apparently none the worse as a result of our second attack. All torpedoes being expended and seas being too rough to use a deck gun, we observed target until certain she wasn't sinking and then set course for Midway.

Target was never definitely identified. Checking radar ranges against binocular field subtended she was seen to be at least 500 feet long; had a low squat stack and not much superstructure. She may have been a tanker or a cargo ship, size 8000 to 10000 tons.

In preparation for firing on this attack (#5), all six bow tubes were made ready as ordered, though I intended to use only three torpedoes. Target had been tracked for nearly an hour on a steady course and speed. I assumed that a salvo of three torpedoes, one to hit, and about a 75 yard spread on each of the others would finish her and leave us with 3 torpedoes for another target.

— page 121 —
U.S.S. GURNARD (SS254) Report of Third War Patrol.

I now feel that I erred in taking the optimistic attitude that three torpedoes would suffice. Having already experienced failures of warheads on 50% of my attacks on this patrol, I should have fired at least four torpedoes in the first salvo with two aimed to hit without a spread.

Submerged during daylight.

TARGET DATA - DAMAGE, INFLICTED

DESCRIPTION: Day periscope contact, visibility good.
Single snip, air escort, no surface escort.
AK of about 6400 tons, similar to Kogyo
Laru.

At time about 7am torpedoes should have
hit, two thuds were heard on sound gear.
At the same time the Commanding Officer
observed a column of water to blow up above
the deck height of target halfway between
her stack and stern. Shortly thereafter
several people on target ran over to where
the water column had risen and looked over
the ships sides. I don't believe warheads
exploded. This water column may have been
from an air flask explosion.

DAMAGE DETERMINED BY: No damage claimed.

(K) LATOR DEFECTS AND DILAGE (Cont'd)

(2) The free surface action of water in the main induction when it is partially filled causes the boat to take excessive angles rapidly. Depth control under such conditions is very difficult and poor.

(3) It is not always possible or prudent to drain the induction piping into the bilges when returning to periscope depth. On surfacing the main induction cannot be used until it is completely drained. This is a very slow process with the present drains. (Opening inboard induction valves to empty water into engine room bilges may flood vital electrical machinery).

There are times when four main engines may be needed immediately on surfacing either for pursuit or escape. On the night of Sept. 15 more than one hour was required to drain the main induction of this vessel. Fortunately the battery had sufficient charge remaining to permit using it with two main engines, taking air via conning tower hatch, for escape. No more than two main engines can be operated using air via the conning tower hatch.

Engineering

On October 2 on starting up #2 main engine a sharp pounding was heard at #9 unit. Engine was stopped immediately and on inspection excessive oil was found in the stuffing box for the division cover of #9 unit. Further investigation revealed that the crosshead nut was 2/3 stripped of locking teeth and had backed off 2/3 turn, causing the crosshead nut to strike the division cover. This in turn resulted in excessive clearance in the oil retainer rings of the division cover. Piston and upper head were removed, inspected, and found to be undamaged.

While this engine was out of commission the bearing jackbolts were scunded and those on #1 and #4 units were found to be loose. Bearing shells were rolled out for inspection and #4 had pounded sufficiently to require replacement. Repairs were made by installing the following new parts:

3. The operation of the SJ radar at all times during this patrol has been most satisfactory. The successful attacks and sinking of two ships during darkness of Oct. 8 and the contact and subsequent damaging attacks on a ship during darkness of Oct. 9-10 are directly attributed to the fine performance of the SJ radar.

The radar officer, Lt.(jg) H. D. FELSHNITAL, Jr. is deserving of great credit for the present efficient state of operation of the SJ radar and for his fine manipulation of it during the above night encounters.

- 38 - ENCLOSURE (A)

U.S.S. GURNARD (SS254) - Report of Third War Patrol.

(7) On October 5 one bearing in the radar motor generator burned out. The bearing was replaced and the motor generator was tested and back in operation 00 tober 9. The SJ radar was operated on the I.C. motor generator during this period. Aside from this trouble, operation of the motor generator has been quite satisfactory.

(N) SOUND GEAR AND SOUND CONDITIONS.

On Sept: 18, 1943 during late afternoon in Lat 26-10 N, Long 144-38 S pinging at 17 KCs by two AS vessels could be heard clearly at 6000 yards. Propeller noises of AS vessels were not heard at any time when submarine was either above or below a -15° temperature gradient. (Gradient started at about depth 150 feet). Can listening gear appeared to be normal. As first depth charges were not close, it is possible that conditions for echo ranging may have been poor.

Sound conditions off Takao, Formosa, Lat. 22-40 N, Long 120-00 S, during afternoon of Sept. 29 and 30 were not good. Propellers could not be heard beyond 3200 yards.

The ball bearings used on the drift stops which hold sound heads out when the hydraulic plant is secured again cracked at deep submergence. It is recommended that a frictionless roller bearing or a larger size ball bearing be used.

1. HEALTH, FOOD AND HABITABILITY.
2. (1) Health in general was excellent.
3. (2) Food was varied and good. Leaks were served at normal times. Salt-tablets and vitamin capsules were available for all hands.
4. (3) Habitability was in general good. It is felt that the ventilation supply of air to the forward part of the ship, especially the forward torpedo room, is not sufficient and that it could be improved by the installation of a booster blower in the control room. Air supply forward of the control room is very meager when four main engines are in use.

(Q) PERSONNEL.
The commanding officer is pleased to report that the performance of duty of all hands was very commendable and in keeping with the highest traditions of the naval service.

The 3 hits obtained on attack #3 were the result of the excellent performances of the Fire Control party following the movements of the target which had commenced avoiding action immediately after attack #2.

The intelligent and highly proficient operation of the Torpedo Data Computer by Lieutenant G.S. SHIONS III was again outstanding on this patrol.

(U) REMARKS.

Blue smoke was noted along torpedo tracks during attacks of our last patrol. Conversation with other submarine commanding officers indicates that such smoke is not uncommon.

While routing torpedoes during this patrol special efforts were taken to see that all oil in after-bodies was thoroughly drained and that a minimum of grease was used in packing tails. In spite of these efforts, torpedoes smoked excessively on attacks of this patrol.

Smoke from torpedoes is a serious imperfection and a decided disadvantage when firing war shots. All endeavors to preserve the element of surprise by making an undetected attack and by eliminating the impulse bubble are immediately thwarted by the appearance of dense smoke tracks which warn targets of the approach and whereabouts of torpedoes.

Subject: U.S.S. GURNARD (SS254) - Report of Third War Patrol - Comments on.

1. The third war patrol of the GURNARD was her second in the Pacific Area and lasted for a period of fifty-two days, twenty days of which were spent in the area assigned.

2. On this patrol the GURNARD maintained the usual aggressive successful standard previously set and only the poor performance of torpedoes prevented her from bagging twice as much tonnage. The limiting factor on this patrol was the expenditure of all torpedoes.

3. A total of seventeen ship contacts were made. The majority of these seventeen were either too small or too distant to close and as a result only five attacks on four worth while targets could be executed. Of those all were hit but only two were sunk due entirely to the fact that fifty percent of said hits were either low order explosions or complete duds. Detailed comment on each of the five attacks is not necessary as two or more hits were made on four of them thus demonstrating that they were well and aggressively conducted.

4. However it is considered desirable to point out certain things in connection with torpedoes:

(a) It is noted that they smoked excessively and that in one instance the target was momentarily entirely obscured as a result. This defect has not been in evidence during training exercises probably because the torpedoes are in the ready condition for such a relative short period of time. It is recommended that exercise torpedoes be made ready and kept ready for a period of from thirty to sixty days and then fired to see if the same condition is noted. If it is and the cause can be determined and corrected it will do much to prevent successful combing of tracks by the Japs.

Subject: U.S.S. GURNARD (SS254) - Report of Third "Air Patrol - Comments on.

(b) The decision of the Commanding Officer to fire low power shots to lessen the force of impact is considered sound but this practice should not be necessary in the future due to not design improvements by forces afloat increasing the efficiency of exploded performance.

(c) The decision to activate one torpedo in each salvo fired is not concurred in and should not again be attempted. However, the Division Commander can well understand and sympathizes with the Commanding Officer's urgent desire to try anything and everything after witnessing numerous and heartbrealing torpedo failures.

5. The material condition of the GURNARD with the exception of a leaky main induction, which will be investigated for correctivo measures, is considered good. The GURNARD will be refitted by the CRIFITN and should be completed during normal refit period, this dependent upon conditions found after a thorough inspection of the H.O.P. engines is made.

6. The health and morale of officers and men is excellent. It is felt that they are to be congratulated on a very fine patrol conducted under disappointing conditions and that they be credited with having inflicted the following damage to the enemy.

Via: The Commander-in-Chief, U. S. Pacific Fleet.
Subject: U.S.S. GURNARD (SS254) - Report of Third War Patrol. (6 September to 28 October 1943).

1. The third war patrol of the GURNARD was the second in Pacific waters. The patrol was typical of the GURNARD's second, in that aggressiveness, attacks and results were all excellent.

2. The attack on the night of October 7-8 against a four ship, escorted convoy was well conducted and the sinking of two ships is a credit to the fire control organization.

3. The GURNARD did not have the new type firing pin in its exploders and, thus, duds probably saved the Japanese at least one ship more.

4. This patrol is considered successful for Combat Insignia Award.

5. The Commander Submarine Force, Pacific Fleet, congratulates the Commanding Officer, officers, and crew for this very aggressive war patrol. The GURNARD is credited with inflicting the following damage to the enemy:

Range on #2 ship, about 500 yards, was too short for a bow shot, angle on bow was 40 stbd. #2 ship maneuvered radically making it necessary for us to go to 80° to avoid a possible collision, swung hard left to avoid passing under this ship and by chance catching a token depth charge from her.

Two hits. I saw this ship sink within one minute. Both targets had been heavily laden, #1 was a collier or ore ship of about 5000 tons with engines aft, #2 was an engine amidship, flush deck type of about 6000 tons. Remained at periscope depth trying to evade escorts one of which had started to unlock depth charges at 0717 I. At 0722 when one escort came close went deep and took evasive measures.

Having determined targets speed and amount of zigs decided to move off track and try to penetrate screen from flank for a favorable attack position. At 2147 commenced closing track for attack. It was necessary to stop twice to permit DD's to pass about 2000 yards ahead. We were trying to reach a firing range of 2500 yards. Then about 3400 yards from target for a 100 stbd track, target zigged about 60 left, making track too large, and a DD appeared to be headed for us. Unevened clear on surface and when sure we weren't being followed resumed chasing target. (As the 4' remaining torpedoes, all forward, had been flooded for the above attempted attack, drained tubes and commenced routing torpedoes, succeeded in finishing two before the next attack) Because of the number and disposition of escorts an undetected attack at a favorable range from the flank appeared hardly possible and not prudent. Decided to overtake target on the starboard quarter of her base course and fire launched after a big zig to the right, this track left something to be desired but it had more chance of success without a counter attack. About 2348' target on approximate base course, about 070°, we were 3200 yards on targets starboard quarter waiting for the right zig which would give us a shot. We had DD's in sight near us about as follows: 040 relative, 2100 yards, 280 relative, 2400 yards, 190 relative, 2500 yards, also noticed a blinking

35.3. CURRARD (33254) - Report of Fourth War Patrol.

(C) : L. H. H. R.

This weather in this vicinity of Lat 34°-00' in
from Long 160 to 140', enroute to area, as described in the narrative, was foul about 60% of the time. And an heavy seas were consistently from this west or southwest and often made it necessary to reduce speed to 3 to 7 knots.

In the area the weather was seasonal, wind, temperature and seas being not comfortable but as to be expected at this time of the year in latitude 33°-34° F. Temperature varied from 42° to 56° F., seas averaged about condition 3, winds about force 2 to 3. Both day and night a low haze partially obscured the shoreline. This made navigation near the cliffs to find shipping both difficult and hazardous. Without the 3rd radar, on several instances we could not have been able to close to coast near enough to sight shipping.

(D) TIDAL INSTRUCTIONS:

Currents in general were unpredictable.

Off KING'S SAIL the currents were consistently to the east, cf about 1.5 to 3 knots.

Sixty miles east of KING'S SAIL the currents ran from 1 to 3 knots and were unpredictable in set, sometimes completely reversing direction in 24 hours. Of 1 SAIL the currents varied from east to southeast and were consistently about 1 knot.

(E) NAVIGATIONAL AID:

Lights:

KING'S SAIL Light was lights most of the time. Characteristics checked with light list.

KING'S SAIL Light was not lights or if lighted was very dim.

KARTER SAIL light was identified by bearings. Characteristics as follows differ from those of light list, fleshing white every 5 seconds, 28 on, 35 off.

U.S.S. GUNNARD (SS254) - Report of Fourth War Patrol.

DAIO SAKI light was lighted but instead of Alt. Fl. white and red appeared to be only flashing white with time characteristics as in light list.

OKAI SAKI light was either off or very dimly lighted.

A white tower at the mouth of TERRYUK KIL, Lat. 34-38.5 N, Long 137-49 J was easily identified, and proved useful with FUJI SAKI for fixing position.

Two lines of lighted buoys or anchors picked boats were sighted east of TERRYUK SAKI. The lines of lights were about 4000 yards apart, lights in each line were about 3000 yards apart. The inner line of lights extended from about Lat. 33-45 N, Long 136-16 E, to Lat 33-30 N, Long 136-01 E. (The above positions are approximate)

swinging ship to avoid the stern escort, it was anticipated that the last two torpedoes would be fired before the ship picked up her swing. The firing intervals being longer than expected the submarine was swinging before the last torpedoes for the gyro angle of 325 on the tube, the fourth torpedo was about 6 to the fourth torpedo whose course was observed the right of the other three tube the firing bearing or hit. This indicates that the firing bearings might target data for the first three torpedoes might have been in error or that the gyro angle set on the last torpedo was incorrectly recorded because of the fast rate of swing of submarine and consequent rapid change of gyro angle.

Firing interval was large because of failure of gyros to match rapidly by power and because last tube was not ready for firing immediately after the third shot.

35.5, GUNARD (35254) - Report of Fourth 'Far Patrol.

(I) MAJOR DIFFICTS AND DELAYS.

Jourd Gear.

As has happened on all previous patrols, the ball bearing drift stops which hold sound heads out when the hydraulic plant is secured again cracked at deep submergence. This has been a common failure on several submarines. It is recommended that an alteration be made to overcome this inherent weakness. The use of more than two drift stops or the use of larger size ball bearings than installed at present or a design using a frictionless roller bearing are suggested.

Hardie Tynes High Pressure Air Compressors.

Reference: BuShips 1lan Number 390013.

Fleece numbers 404 and 487 - Coil straps.
Fleece numbers 402 - Coil, third stage intercooler.

Coil straps (Fc. 404, 467) are brazed to each coil. Operations to date have shown that during use this third stage coil nest expands longitudinally and coil straps, which are brazed to coils, break loose from coils. Since in most cases the brazing joint is strongest, the strap in pulling loose tears small bits of metal from the coil proper. The damage caused is sufficient to cause leaks at some of these weakened sp ots after about 400 hours of compressor operation. It is recommended that an alteration be made to eliminate this source of failure.

Gyro Regulator Indi cator.

On attack #7 the lark 1 iod 2 gyro angle indicator regulator in the forward torpedo room failed to function electrically and it was necessary to match pointers and set gyro angles by hand.

Upon inspection (after the attack) it was found that contact, on the right drive relay (Ord No. 212605) of the lark 2 iod 1 controller unit, had fuzed reenergizing the entire relay inoperative.

— page 200 —
35.5. GUARD (53254) - Report of Fourth Year Patrol.

(K) HATCHES AND DIESEL.

This listing has been a source of repeated failure and many relays have been used since the commissioning of this vessel.

It is recommended that the entire relay as well as the contacts be redesigned for heavy duty and more nearly continuous operation.

Full Supply Ventilation Blower.

On December 9 this hull supply blower seed rheostat (Cutler Harmer Flan 3305) snorted out and was replaced with a spare.

This failure of this rheostat was noticed when the impeller of the hull supply blower carried away. This indicates that the failure of this impeller may have been caused by excessive overspeed.

Investigation after opening blower casing revealed the impeller to be forced into ventilation piping and a complete wreck. A spars impeller for this blower is not supplied with on board spares. It must be replaced with a new blower, ventilation in this ship is very poor, the air condition plants are of little use, and the temperature in the maneuvering room becomes excessively high.

Using materials on board, silver solder and remnants of the old impeller, a replacement impeller was fabricated on board. The Commander Officer takes this opportunity to commend Officer A. A. SIGARILLO for their ingenuity and dexterity in performing this task.

Engineering.

On November 29 the rubber flexibles couplings (LB Co Flan 2172-61 Fco. 8) between the attached lub oil pump and the propeller of #3 main engine carried away. To spares were carried on board so the engine was decommissioned until arrival of May, where four new rubber and two spare metal couplings were re-ceived. Also installed new couplings on main engines.

In December 27 the following parts were removed in the fuel oil purifier: (1) 2 idler bearings, D.W.G. 1H43-3, 3y#303; (2) drag bushing, D.W.G. 1H37-10, 3y#96; (3) 2 brake lining rivets, D.W.G. 1H20-4, 3y#63; (4) brake band lining, D.W.G. 1H20-4, 3y#63. While bracing heavy seas it was necessary to secure the forward engine room to prevent salt spray coming through the induction flow. The following are the units. It is again urgently recommended that they be located in a more accessible, convenient, and safer place during the next navy yard overhaul.

On January 1, 1944 the lower fuel heater on 1st in engine sprang a leak in the return line at 3d lower fuel pump. Attempts to silver solder this crack were unsuccessful. A spore heater was installed and the engine put back in commission.

On January 1, 1944 while running at 630 RPM, an 850 Kt, a loud crunching noise was heard in the vicinity of the gear train of 1st in engine. The generator was tripped and the engine was stopped immediately. After removing the gear train inspection covers, an attempt was made to jack the engine by hand without success. On reversing the direction of rotation one half of a well cleared gear tooth tumbled into the bottom of the gear case. A visual inspection then revealed approximately every fifth tooth dented on the upper blower drive gear and a similarly dented one on the upper blower idler. No broken teeth were visible nor could the broken one be located by fieeling. The engine jacked with difficulty. Removal of the blowers for a more thorough inspection will be necessary in order to determine the full extent of this derangement. Engine hours since gear renewal on December 7, 1943 - 169.7.

Electrical.

During the last refit while the auxiliary generator was open and being cleaned by the relief crew, salt water from the main engine air induction, which was being given a hydrostatic pressure test, splashed into the generator casing resulting in a low armature insulation reading. The armature was cleaned and the cold insulation reading subsequently reached 750,000 ohms. The readings gradually dropped until reaching 225,000 ohms on December 20, The armature was cleaned and heated without results and on December 22 was flushed with battery water. After drying out, readings were taken and the shunt field had dropped from 3 megohms to 50,000 ohms. Each field coil was isolated and the lower nickel one found to be at fault. The end bell was disassembled and the coil removed, cleaned, heated, and nursed with negative results. The generator was reassembled and put out of commission on December 27, 1943.

General

The HOR engines of the GURARD have operated for an average of 24.1 engine hours each, have taken this vessel through four war patrols and over 45,000 miles. The Commanding Officer does not mention this as praise for HOR engines, which he still believes to be unreliable, as the above was not accomplished without an excessive number of major derangements.

The fact that the GURARD has been able to operate so extensively with these engines is not credited to luck or to the fact that the HOR engines of the GURARD were better than those of any other submarine of Squadron Twelve.

The engineering personnel of this vessel have paid great attention to rigid and frequent inspections to forestall trouble and have placed great emphasis on proper operation and upkeep. The engineer officer has assured that inspections, operation and upkeep are always carried out with meticulous attention to details and good engineering.

practice. The latter are considered the reasons why the GUNARD has been able to carry on with the HOR engines.

It is with the greatest of pleasure that the Commanding Officer commands the engine room personnel and especially the engineer officer, Lieut. R. H. Harwood for their fine attention to duty and the excellent results obtained with these inherently poor engines.

(L) RADIO.

Reception.

The 4525 Kc band was the most dependable frequency on station (Lat 34° N, Long 137° S). All frequencies were stronger and more readable after 1700 Z, fading started about 1930 Z. 16.63 Kc began fading about Long 142°. The one time that 56 Kc was received while on station, it was heard better than any of the regular frequencies. It is considered that the optimum reception at this station (Lat 34° N, Long 137° S) would be on 56 Kc at 1600 Z or 4525 Kc from 1700 to 1800 Z.

Interference.

On station interference was heard from two local transmitters which opened up coincidentally with both the 1100 Z and 1300 Z schedules, these often faded out before the end of the schedule. One of these transmitters was heard every night on station. There was no interference on the 1500 Z schedule.

Press was received on 6270 from KF3, Palo Alto.

Our transmissions were made on 8470 Kcs, 12705 Kcs and 450 Kcs. They were received by KPR (Dutch Harbor), KCN (Fiji), KNI and VF1 (Unidentified). VF1 instructed us to send VF1, this was ignored.

No acknowledgement sent for CHIARAD Serial one was received.

(RADAR.

OPERATION.

STA Radar.

The operation of the high power STA radar was completely satisfactory at all times during this patrol. Ranges obtainable with this radar are about four times greater than those of the old ST. It is worthy of note that every contact made on the surface was by radar and that radar was used to obtain data for every attack. The warship which was attacked on the night of Dec. 27 was first picked up by radar at 33,000 yards. This ship with its 10 escorts would have passed unsighted had we not had radar. Land targets were picked up consistently at 90,000 and 100,000 yards. Very small patrol boats were picked up from 6,000 to 8,000 yards. Low flying aircraft were tracked on the ST at 7,000 yards.

The STI scope was very valuable. This scope should be located immediately adjacent to the TDC and range unit.

The installation of the ST with STI scope provides only for high speed training. It is recommended that voltage control be installed with this training gear to provide for slow speed power training. (Prior to departure on patrol the U.S.S. GRIFFIN provided a jury rig for slow speed power training. The resistors for voltage control in this rig burned out when the training torque on the radar mast increased because of the rolling of the ship in heavy seas).

- 47 - [HISTORY (A)]

— page 207 —
35 Radar.

The performance of the 5D radar was satisfactory. No low flying aircraft were encountered while using the 5D. Hence it is impossible to state whether the type CRV 66 AF5 antenna installed during the last raft improved the 5D's ability to detect low flying aircraft. It was observed, however, that no signals were obtained for aircraft flying directly overhead.

Interference.

During morning and evening darkness, Dec. 19 noted interference on 5D radar from vicinity of JIKURA SHL and CHAI SAKI. During n ight of Dec. 19 noted interference on 5D radar from two different seawarc directions as from ships.

CUC Radar Detector.

This equipment was tested at 1:1dway with in-different success. Tests were made with various antennae, the 3D antenna gave the best results. The Dg receiver was used with this equipment. Coaxial cables was used for all inter-unit connections.

During surface attacks the CUC equipment operated continuously but with no results. It is felt that the frequency range of the CUC equipment is too low to detect the radars which might be encountered. It is also felt that the tuning is too sharp on this equipment. The possibility of the CUC being tuned to the proper frequency at the instant a searching radar is trained towards the detector is too small to make detection positive.

Radar Derangements.

Only one casualty developed in the 3D. This was of a very minor nature and consisted of a broken wire which resulted in the loss of a 30 minutes operating time.

(1) RADAR.

(2) In addition to the present location of the FFI being inconvenient, difficulty was encountered with salt water getting inside the case. Located as the FFI now is, water coming down the conning tower hatch splashes through the ventilation slits in the FFI case. It is recommended that the FFI be relocated near the TOC.

(3) Four IT tubes were replaced because of reduced output. These tubes tested satisfactorily but were not sufficiently sensitive to give good results. The requirements placed on the IT tubes seems severe for not all new tubes operate satisfactorily and the useful life of tubes is short.

(4) The limiter tube in the ARC circuit was replaced because of unstable tuning. After about 100 hours operation it was again found necessary to resume the ARC circuit.

(5) Three regulated rectifier, rectifier tubes were replaced because they had become gassy. In replacing these tubes it was found necessary to reject several new tubes because they were gassy.

(6) A broken coaxial cable between the range unit and the range indicator caused the range stop and periscope sweep to disappear. Because of the location of the cable jacks on the range unit, there is danger of these cables becoming broken from contact with the operating personal. A small protecting bracket would prevent this.

(7) It was necessary to clean the slip rings on the antenna pedestal to overcoax erratic lobe switching.

35.3. GURARD (38254) - Report of Fourth War Patrol.

(1) RADAR.

(6) It was found necessary to re-align the antenna bearing indicator because of an error introduced during installation. Apparently no provision had been made for doing this conveniently. It was necessary to disconnect the sheeting and rotate the antenna and bearing indicator independently. By this method bearing changes could only be made in five degree steps.

Radar Iotor Generator.

In spite of several overhauls and constant attention the radar generator has, because of its low capacity, never delivered power at a voltage constant enough to insure optimal SJ radar performance. With the addition of the FPI and the resulting increase in load from FPI it is not possible to operate the SJ and FPI on the radar motor generator. It is necessary to use IC motor generator power when SJ and FPI are both in use.

Changes of load on the IC system causes fluctuation of radar voltages and therefore poor radar operation.

It is not possible to parallel the operation of the two IC motor generators now on board. Also the present installed switching arrangements does not permit operating these IC motor generators simultaneously on separate circuits.

It is recommended that: (1) another IC motor generator be installed for use with radar only or (2) that provisions be made to operate the two IC motor generators now on board simultaneously on separate circuits.

This will be made the subject of a separate letter.

(N) SOUND GEAR AND SOUND CREDITS.

Sound conditions in the area (southwest of HONSHU) were good; propeller noises of targets could be heard from 5,000 to 7,000 yards. An unusual amount of airship fins noises were heard; these about 70% of the time.

Temperature gradients in the area were practically negligible, there being on the average less than 3° F drop between the surface and 300 feet.

It is regretted that we produced so little destruction to the enemy for the expenditure of our first sixteen torpedoes. The Commanding Officer is certain that the causes for this poor performance can and shall be corrected.

Judging from the ease with which we were able to close targets on the surface at night while remaining undetected the new gray and black camouflage is very effective and desirable.

Subject: U.S.S. GURNARD - Report of Fourth War Patrol.

1. GURNARD's Fourth War Patrol occupied a period of 35 days (FEARL to FEARL) exclusive of a five day period of emergency engine repairs in MIDWAY; of which eight days were spent in waters off the southeast coast of HOUSTON. The patrol was terminated by expenditure of all torpedoes.

2. This campaign of GURNARD was conducted with the ultra-aggressiveness which has characterized all GURNARD patrols. The Captain did not hesitate to go in close to shore when it was necessary to do so in order to get the targets.

3. There were contacts with 17 enemy ships or groups thereof; of which seven embraced targets worthy of torpedo fire. There were seven aircraft contacts.

4. A total of seven attacks were made for seven hits out of 24 torpedoes fired. The Commanding Officer's analyses of these attacks are most thorough and this command can add nothing further to the reasons advanced by the Commanding Officer for the misses. It is noted that on attacks numbers 2 and 3, two torpedoes of eight fired exploded on the beach; on attack number 4, one torpedo of four fired exploded on the beach. The other torpedoes of these attacks did not explode on anything. This suggests the possibility of more warhead or exploded troubles.

5. GURNARD succeeded in making four successful attacks on strongly escorted ships. The Commanding Officer, officers and crew are congratulated for achieving the destruction of two medium freighters, as well as damage to a medium freighter and a large, unidentified man-of-war.

1. The remarks and summation of damage made by the Commander Submarine Division ONE TWENTY TWO are concurred in, and, although the percentage of hits was below average, this patrol was the usual aggressive one expected from the GURNAUD.

2. It is regretted that the GURNAUD must go to the Navy Yard for reengining prior to going on another patrol, especially after having completed three successful patrols in succession.

3. The Commander Submarine Squadron TWELVE congratulates the Commanding Officer, Officers, and Crew of the U.S.S. GURNAUD for having conducted another fine patrol and inflicted damage to the enemy.

— page 216 —
1. The Commander Submarine Force, Pacific Fleet, was conducting patrol in the area.
2. In spite of the extremely heavy anti-submarine activity in this area, the GURNARD carried on a determined war patrol which finally resulted in inflicting severe damage to the enemy. Numerous personnel errors in the fire control organization caused misses in several attacks. These, however, were corrected later in the patrol. All attacks were extremely aggressive. The night attack on 24 December against an important armed merchantman with 10 escorts was extremely aggressive and well executed. Undoubtedly the new camouflage was of help in allowing the GURNARD to pass through the screen to press home his attacks on several occasions.
3. Of note... an apparent Japanese trick of using a tug to tow a derelict hulk where a submarine's prosonco is suspected in hops that it will be fired upon and thus reveal the location of the submarine. The GURNARD recognized this as a decoy, refrcined from firing, and was able to make a successful attack shortly after on a convoy. Now use of depth charge to attack a pursuing submarine should be noted.
4. This patrol is considered successful for Combat Insignia Award.
5. The Commander Submarine Force, Pacific Fleet, congratulates the Commanding Officer, officers, and crew upon another aggressive, determined, and successful war patrol. The GURNARD is credited with having inflicted the following damage upon the enemy:

(A) PROLOGUE.

Arrived Pearl Harbor from fourth war patrol on January 7, 1944. Departed Pearl Harbor for Navy Yard, Mare Island January 11. Arrived yard January 18. Limiting work item replacement of four H.O.R. main engines with Winton 278A engines. Accomplished all necessary repairs and outstanding alterations except installation of conning tower-control room electric cable trunk. Departed Mare Island March 25, 1944 arrived Pearl Harbor April 1.

Spent four days on voyage repairs and one week on training. Fired five exercise torpedoes and devoted two days to a convoy exercise with friendly ships. (Operations on the attack teacher and training approaches at 8. on single targets with one or two escorts are fine for indoctrination of fire control and ship control parties. Such operations do not simulate the problems encountered when engaging an enemy convoy of several ships and escorts. Exercises with friendly convoys provide much needed training which is not otherwise available and are of very great value in preparing commanding officers for actual combat with enemy convoys.)

Degaussed and conducted sound listening test of equipment which had been reported noisy on test at end of Navy Yard overhaul. Noise of both bow and stern planes in hand power is greater than allowed limits, reasons undetermined.

Weather squally. Sighted masts of a ship in clear spot on horizon to northwest. Commenced approach. Subsequent observations revealed target to be either a large cruiser or battleship with two destroyers as escorts. All were zigzagging radically, speed estimated by propeller count and appearance of bow and stern waves of destroyers was about 23 knots. All ranges were poor under the prevailing visibility, target and escorts were partially obscured by rain at every observation. On raising periscope for final set up target was hidden by a destroyer which passed about 300 yards ahead of us. This necessitated a delay in firing. The opportunity of firing on a favorable track was lost. While waiting; swung ship in an endeavor to reduce gyro angles.

At 0809 H fired 6 bow tubes mean range 2300 yds. track 151, gyros 323.

Stern wash of destroyer partially obscured torpedo tracks. One poppet valve failed to open normally. To avoid broaching flooded negative which carried periscope under before torpedoes could have reached target. Heard two hits on sonic sound gear at proper timed-interval. About a minute later destroyers commenced unloading first of 32 depth charges. Nearly all were in patterns, some were too nicely placed for comfort.

At 0905 H while on way to periscope depth the sound of approaching destroyer screens made going deep again more discreet. Prior to firing a turn count of about 285 r.p.m. on target was obtained. About 0920 H turn

Date: 18 May 1944
Location: Long. 125-45E
Signals: 2nd torpedo attack
Target: 3rd torpedo attack
Description: Target was at first thought to be a large cruiser
   hence torpedoes were set at 10'. Target had two
   twin turrets forward, a solid tower fore mast, about
   130' high, main mast was equally high, upper part
   was stick type. She had one straight stack. Study
   of ship identification data subsequent to firing
   shows that target was a battleship.

DAMAGE DETERMINED BY: Two hits heard on sonic sound gear. Target
   though steaming at speed of at least 19
   knots when hit was within four miles of
   firing point one hour and 27 minutes later
   and was tracked at that time as making 15
   knots.

FIRE CONTROL AND TORPEDO DATA.

TYPE ATTACK: One of two ships steaming in line of bearing on zig zag course. First sighted smoke, then lost it in a rain squall, subsequently sighted ships in clear atmosphere, range about 7000 yards.

Visibility good, seas calm, nimbus clouds. Targets could be heard on sound gear at 6000 yards. No air screen noticed.

Submerged day periscope attack using plot and TDC, marked on continuously while firing.

Fired two (2) torpedoes. No hits. Sighted after firing by sub chaser escort which was about 400 yards from GURNARD.

Torpedoes were set at 6' depth with a spread of 30'L and 30'R. Torpedo run was about 1050 yards. Hence torpedoes were spread about 325' apart. Torpedoes either passed under, ahead, astern or if all firing data was exact they may have passed one ahead and one astern of target with the spread used.

TARGET DATA - DAMAGE INFLICTED

DESCRIPTION: Very large, engines aft type tanker. No silhouette in O.N.I 208-J similar to it. This ship was seen head on during one phase of the approach and noted to be very broad. The three torpedoes which hit were spaced about 490' apart at the target as determined by spread used, range of target and distance run of torpedoes computed from time of torpedo run. Also at time of firing target filled more than 70 of periscope field in high power which indicates it was more than 520' long. The commanding officer estimates that this tanker was off at least 17000 gross tons.

SHIPS SINK: One (1)

DAMAGE DETERMINED: Three 4 hits plus two explosions aboard tanker. Explosions were about two seconds after first and third torpedo hits. One later after last hit target was seen with 2 superstructure aft after, almost shooting at least 100' in the air; also it was setting aft. Fifteen minutes later near district ship breaking up noiseless. After stack to scope depth one hour and above minutes after firing there was no sign of tanker. While patrolling the same vicinity two days later an oil slick covering a very large area was very perceptible.

FIRE CONTROL AND TORPEDO DATA

TYPE ATTACK: Day submerged periscope attack using TDC, plot and marking on continuously while firing. Target first contacted by periscope sighting. Weather clear, visibility good, seas calm. Sound conditions good, listening range about 6000 to 7000 yards. No air screen observed. Screens as indicated by sketch in narrative were patrolling their stations and S/M was not detected until after firing. Evasive tactics used - deep submergence and silent running after moving away from firing point at high speed.

Although this target was estimated to be of great, draft, torpedoes were set at 10' for following reasons:

(1) Study of patrol reports indicates tankers are hard to sink even when hit deep.
(2) Hits low may open bottoms of ballast or fuel tanks but tops may remain tight thus preserving some buoyancy and keeping tanker afloat.
(3) Hits from torpedoes set at 1/3 draft may:
   (a) Rupture sides and maybe tops of tanker. (Hits high on sides of tanks both vent and flood tanks.)
   (b) Blow oil or gasoline into air and ignite it from blast of torpedo explosion. Any fire thus started makes damage control aboard tanker more difficult and may make it necessary to abandon tanker.

1. U.S.S. GURARD (SS254) - Report of Fifth War Patrol.
   (I) MISS.
   No mines or any evidence of mines, mine laying or sweeping were encountered.

(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS.
   Destroyer escorts of convoy attacked on May 6 were all using echo ranging in hand keying each one on a slightly different frequency, from about 17 to 22 kilocycles.
   Other destroyers contacted and at speeds over fifteen knots were not heard echo ranging. They resorted to echo ranging for searching after our presence had been discovered and usually steamed at speeds not greater than 12 knots while echo ranging.
   The escort of ship contact #17 used echo ranging, automatic keying, frequency about 19 K.c., while cruising at 12 knots.
   The depth charges heard and felt this patrol seemed louder and of more power than those encountered on previous patrols.
   (This may be our imagination).
   From the number of charges heard on several attacks it is estimated that 1300 ton destroyers carry between 30 to 40 depth charges.
   Evasion tactics consisted of running away from firing point at full speed for about five minutes, then silent running at deep submergence endeavoring to keep A/S vessels astern. With sea conditions existing after each attack, evasion at periscope depth was not considered wise.

(K) MAJOR DEFECTS AND DAMAGES.

Torpedoes
In attack #3 at 1107 H on May 24, four (4) forward and four after tubes were made ready for firing at a depth of 60 feet. In maneuvering, a depth of 90 feet was attained with the muzzle doors open. Tubes #7 and 8 were fired and about two minutes later upon starting to a depth of 300 feet the other six tubes were secured. Evasive tactics were carried on for 1 hour and 20 minutes. Tubos #3,4,5,9 and 10 which were loaded remained flooded for about one hour and 30 minutes with water at normal pressure (atmosphere), (did not want to blow down tubes during silent running).
After securing from evasive tactics, pressure in the boat was pumped down and inspection of torpedoes in tubes was started.
The following conditions were found about 1300 H:
(1) Torpedo #41402 in #4 tube was found to have approximately

— page 266 —
4.2 gals. of water in the afterbody upon draining it. The gyro pot was flooded. The pot and gyro were washed with fresh water and alcohol and then blown dry with air. After oiling the gyro, was replaced and locked in position.

(2) Torpedo #41251 in tube #3 was found to have approximately 2 gals. of water in it and very little water in the gyro pot. Due to the lack of time before going to battle stations again this gyro was not pulled.

(3) Torpedo #41282 in tube #9 and torpedo #26553 in tube #10 were both drained and found to have approximately 4 gals. of water in each after body and both gyro pots completely full of water. Each gyro pot and gyro was washed with fresh water and alcohol then blown dry. The gyros were locked back into position after lubricating. Both torpedoes were routed and reloaded into the tubes.

(4) Torpedoes #41406 and #41403 in tubes #1 and #6 respooled very near not pulled due to the lack of time before the next attack. (1414 H May 24)

Torpedoes #41402, 41451, 41406 and 41403 were fired on attack #4 at 1414 H May 24 and ran normally.

Electrical

The pitomoter log required about fifty (50) man-hours of overhaul work and adjustment in order to be kept in operation. Enroute to area the cause of false readings and fluctuations were investigated and found to be caused by corroded contact lever shaft bearings (Part 42 I.C. Inst. Book 36 FF). After extensive depth charging on May 6, errors were again noted and overhaul of two control unit revealed the bullows assembly distorted. Renovation of this unit (Part 28 I.C. 36 FF) and subsequent mechanical and electrical adjustments made the system operative until subjected to further depth charging after which new settings were required for the contacts.

(K) MAJOR DEFECTS AND DAMAGE.

Hardic Tyros Air Compressor Third Stago Cylinder Shll (continued)

On May 18, 1944 the third stage cylinder shell of the port Hardic Tyros Air Compressor developed several small leaks. At this time the air compressor had been in operation 58 hours and 20 minutes since the recent Navy Yard Overhaul.

Bracing aboard was not practicable due to lack of facilities for procoating. Attempts made to seal the holes with solder were unsuccessful.

At Johnston Island the shell was brazed in the shop. After gutting underway the shell was milled by hand and reinstalled. During subsequent tests a small crack developed down to the first stage suction valve caging. As further repairs were not possible on board, it was decided to run the compressor by starting it without cooling water, and by draining the shell before securing the compressor.

This procedure of building up air pressure before admitting cooling water kept the cooling water from entering the air cylinder and proved satisfactory for limited operation. The compressor was used in this manner throughout the remainder of the patrol.

(L) RADIO

While on station, 9250 Kcs was the only reliable frequency. 4370 Kcs. was heard occasionally, other VIXO frequencies were not heard. All serials were received.

Interference due to atmospheric conditions was experienced for most of the 1200 Z sked, but was less noticeable on later scheduled U.S. ships. When within 10 miles of the mountainous coast of Mindanao, schedules were almost unreadable. On May 16 and May 18 it was necessary to run away from the coast to obtain a readable signal. A local transmitter tuned near 9250 Kcs interfered with schedule reception at irregular times, when we were in the vicinity of 5-30 N, 126-00 E. This did not seem to be deliberate jamming.

All transmissions were made on 8470 Kcs, and were received by VIXO or VHX. On 18 May a contact report was sent blind from 45 feet using SD radar antenna.

(M) SD-2 RADAR

Operation of the SD Radar was generally good for 540 hours. With few exceptions Radar Contacts on planes came prior to sighting by the lookouts, the farthest contact being made on a plane at 32 miles. The minimum range of contact was about 6 miles. Land contacts were made up to about 45 miles at various times during the patrol. The frequency of the SD-2 was not changed to 118mc as suggested by dispatch as the frequency was 117mc which is the top of the frequency band of the available antenna wings. An excess of random noise was noticed on the SD-2 screen throughout the patrol. The source of this interference is from within the ship, but could not be determined during the patrol.

Two breakdowns occurred during the patrol.
(1) On 2 May the 8014-A main oscillator tubes failed and were replaced by a pair of new ones.
(2) On 2 June the SD-2 screen went blank. The transmitter appeared to be operating normally. The trouble was traced to the hi-voltage rectifier in the Receiver Indicator Unit. Filter condenser C256 had shorted to ground. This overloaded transformer T202 and burned this transformer out. With no spare available, a temporary setup was made using the test oscilloscope in place of the radar scope. This worked satisfactorily.

SJ RADAR

The operation of the SJ was generally good. Numerous difficulties were encountered in the Transmitter Receiver Unit which accounted for a total loss of about four days operating time. Operation was excellent for 780 hours. Ranges up to 115,000 yards on islands of an elevation 5000 feet were noted. Only two ship contacts were obtained while in the area. These were small boats, not sufficient to warrant a torpedo.

The following difficulties were observed:
(1) On 16 April the Range step started jumping; readjusting R587 and C539 didn't remove the difficulty. All circuit elements checked all right so finally an additional 100 micro micro

— page 269 —
1. U.S.S. GURARD (SS254) - Report of Fifth War Patrol.
2. (N) SJ RADAR
3. farad condenser was added in parallel with C539. This allowed adjustment to be made so that jumping occurred only beyond 40,00 yards.
4. (2) On 24 April the step and precision sweep on Range Indicator disappeared. Cause was a broken co-axial cable.
5. (3) On 7 May a short 'developed in transfer switch box.
6. (4) On 15 May the SJ motor generator unit speed control failed. Ship's force was unable to locate or remedy this failure. The SJ was operated from the IC motor generator for the rest of the patrol.
7. (5) On 16 May the SJ radar started burning out fuses F9 end F10 in the hi-volt-ge circuit. This trouble was finally traced to C22B in the bias generator circuit which was partially shorted to ground lowering the bias voltage about 200 volts.
8. (6) On 20 May on trying to replace the TR tube as recommended it was found that the spare was faulty. The original tube is still operating at reduced efficiency.
9. (7) On 26 May indications similar to those on 16 May occurred. The trouble this time was traced to an open in transformer L1 in bias generator circuit. Temporary repairs were made to the coil so operation could be resumed. On turning set on a second time R6 in the charging diode cathode circuit burned out. This was caused by a grounded magnetron which had probably been grounded by the excessive current caused by the failure of the bias generator circuit.
10. (8) On 3 June V16 'n Range Indicator failed, giving no stop.

The trouble in the Transmitter Receiver Unit rccoucred several times and appears to be of an intermittent nature. It is felt that the cause is an intermittent open in L-l which can not be totally repaired. An intermittent failure here would change the bias sufficiently to cause excessive plate current to flow and burn out F9 or F10.

(N) SOUND GEAR - HD SOUND CONDITIONS

Sound conditions were in general very good on every attack. Approximate sound ranges on each attack are stated in attack data paragraph (E).

The performance of the J.P. sound gear was very satisfactory. This is considered to be very worth while equipment. It usually out ranges supersonic listening gear.

(d) Number of unqualified men making their first patrol 12.
(e) Number of men advanced in rating during patrol 9.

Two officers completed work for qualification in submarine during this patrol.

The performance of duty of all hands left nothing to be desired and was in keeping with the highest tradition of the Naval Service.

Owing to the vicinity of operations more days were spent submerged on this patrol than on any previous patrol of this vessel in the Pacific. There was a noticeable drop in efficiency of all hands after 17 consecutive days of submerged operations. After two days of surface operations mental and physical reactions appeared about normal again.

(U) REMARKS

The lubricating oil consumption of the 278A Winton engines has been a source of much concern. Lubricating oil tanks and engines were filled to capacity at Johnston Island. In order to insure that lubricating oil endurance would at least equal fuel oil endurance it was found necessary during this patrol to reduce the lubricating oil pressures on all main engines. The

(P) HEALTH, FOOD AND HEALTHABILITY

(1) Health in general was very good. There were a few minor ailments, bruises and lacerations which did not cause any lost man hours. Time was lost for the following causes:

Lymphadenitis, It Auxiliary #1403 - 5 sick days
D.V. (Cat. fever, Acute) #2122 - 3 sick days
Calculus, Right Kidney - 6 sick days

There is one suspected case of chancroid which developed about three weeks after departure on patrol. Subject man has been isolated to the extent necessary to prevent contamination of other personnel.

(2) Food was varied, well prepared and excellent. The new jigs cream maker is a great help for desserts.

(3) As the ventilation to the forward battery and torpedo rooms of this vessel had not been satisfactory when operating in tropical waters a booster blower with a one half ton cooling coil was installed in the hull ventilation supply line in the control room during the Navy Yard Overhaul. This trial installation made a marked improvement in the ventilation and temperature of the above two rooms. As a result habitability throughout the ship was very good.

This installation is being recommended as a standard class alteration in separate correspondence.

1. On starting.
2. After engines have been idling.
3. When ever load is increased regardless of the amount of increase or of the previous load.

The smoke density varies and persists from five to twenty minutes depending upon how long engines have been idling and how much the load is increased from that of the immediate previous loading.

Such huge clouds of smoke are a peril in day time. During night attacks when it is usually necessary to vary speed and consequently engine loads in reaching a firing position, the resulting smoke clouds are a bother of no small account both as regards revealing the submarine's presence: before the attack and her position after an attack. Last but probably the most serious, under some conditions of wind smoke obscures the target when at or near the firing point.

The commanding officer realizes that all of the above is known. The general prevailing opinion in the submarine service is "Winton Engines Have Always Smoked".

I feel that great pressure should be exerted to insure that positive action is prosecuted to eliminate the excessive smoking which is a most serious military defect in an otherwise very reliable and fine operating engine.

FIRST PERSPECTIVE to
U.S.S. GURMARD - Report
of Fifth War Patrol.

From: The Commander Submarine Squadron TWELVE.
To: The Commander-in-Chief, United States Fleet.
Via: (1) The Commander Submarines, SEVENTH FLEET.
(2) The Commander SEVENTH FLEET.

Subject: U.S.S. GURMARD (SS254) - Report of Fifth War Patrol.

1. The fifth war patrol of the U.S.S. GURMARD conducted
enroute Pearl Harbor to Frenantle and in the assigned patrol area in
the vicinity of the Celebes Sea was of 57 days duration. The entire
patrol was conducted with the current weather conditions and determination
characteristic of GURMARD's previous patrols. Nineteen torpedoes
were fired in four attacks on escorted enemy vessels and resulted
in twelve hits. Valuable information regarding enemy movements was
also obtained from reconnaissance in Davao Gulf.

2. (a) Attack #1. Six torpedoes were fired in a de-
termined periscope attack on a large escorted convoy, resulting in
six hits on four ships. GURMARD was heavily depth charged and held
down until dark. Returning to the scene of the attack after dark
GURMARD attempted to sink a burning, abandoned ship in a sunfire but
after firing 21 rounds of 4" with no apparent effects except being
fired one torpedo to insure its sinking.

(b) Attack #2. A submerged attack on a probable PP
screened by 2 DD's was well handled. GURMARD was unable to fire at
the most favorable moment due to a DD passing close aboard and hiding
the target from view. Six torpedoes were fired and two hits were
heard on the sonar near 'before the inevitable depth charging began.
It is reported that fault' operation of one torpedo tube popped valve
made it necessary to re-deep before torpedoes reached the target.

(c) Attack #3. Two torpedoes were fired on two
small AK's escorted by two craft of the sub chaser type for a mean
range of 1050 yards after a submerged approach. Both torpedoes raised,
possibly due to under running, a lightly-locked, shallow-draft ship.
The escorting vessels dropped four close depth charges.

(d) Attack #4. Four torpedoes were fired from the
only bow tubes available at the time at a large tanker in a convoy
consisting of 2 AO'1, 2 AK's, and 3 DD's. Excellent firing position
was attained in an unprotected submerged approach. Five explosions
were heard, three of which echoed as timed hits and the tanker burst
into flames. GURMARD was promptly subject to a depth charge attack
by the escorting destroyers.

1. Chidori did not head for a submarine.
2. Men in boat rowed frantically away from submarine position.
3. Periscope was not sighted during subsequent approach on Chidori during which 31 observations were made between 0759 and 0924.

At 0759 Chidori reversed course and headed towards submarine, CDR-4 continued to westward and eventually passed out of sight. Commenced approach on Chidori, 'Subsequent actions revealed she was returning to search for submarine. Chidori maneuvered on radical courses within 3000 yards of submarines. Submarine maneuvered to read position for stern shot with electric torpedoes. Stem tubes were made ready and then secured at 0821 and 0905 when target maneuvered away just before reaching a spot firing position.

Finally at 0924 fired four electric torpedoes from stern tubes, range 900 yards, track 1003, mean gyro 19 R, depth 4 feet, no hits. See paragraph (H). Target did not change from her course at time of firing until 0927. At 0926 heard an explosion. At 0926 Chidori heading towards submarine with small angle on bow, went deep and took evasive action. At 0932 heard 3 explosions. (Following chart shows tracks of submarine, CDR-4 and Chidori).

Radar contact at 2700 yards. Sighted unidentified craft (Ship contact 16). Tracked and determined this vessel to be on approximate course 2330 T, speed 5. Closed to 2100 yards, observed target to be too small for torpedo but unable to determine whether it was a small junk, patrol craft or a submarine flooded down (weather rainy). No indications that it was using radar. This didn't prove that it wasn't a U.S. submarine.

Another U.S. submarine was expected in this vicinity tonight or tomorrow. As there was little to gain by firing on a small junk or patrol but much to loose in shooting at a friendly submarine decided to avoid further contact and cleared vicinity.

Remarks: Attack #1A - no hits observed. Target was observed to be zigzag while firing. Applied course change to T.D.C. between each shot, hence different track angles. Target was small and was in light draft with propeller about 50% awash. Illness could have been caused by firing on knuckle of zig or more probably from undermining small shallow draft 'target'.

The following analysis substantiates the assumption that torpedoes ran under target:
(1) A range error of (/) or (-) 900 yards applied to actual range used changes gyro angles less than 10°.
(2) Target could have been on any course between 252° and 337° and with the spread employed, assuming speed used was correct, at least one torpedo of salvo would have hit.
(3) Speed was probably correct, or nearly so, as two hits were obtained while using the same speed on target #2 AK of the same convoy.
(4) Assuming speed was in error it could have been (-) 2 knots or (/) 1.8 knots from that used and still not cause all torpedoes to miss.

Remarks: The reason for no hits is not known. Sound heard noise of electric torpedo but could not tell whether all four ran normally.

Post firing analysis shows that:
(1) Range could be (-) 600 or (+) 2000 yards different from that used without changing gyro angle on firing.
(2) At the spread used at least one torpedo should have hit under each of the following individual errors in data:
   (a) Speed / 4.5 knots.
   (b) Speed - 4.5 knots.
   (c) Target course 35° towards.
   (d) Target course 70° away.
(3) If target course was in error 30° away, speed could still have been off (+) or (-) 4.5 knots and one torpedo should have hit.
(4) If target course was in error 30° towards speed could still have been (-) 2 knots or (+) 4.5 knots and one torpedo should have hit.
(5) Torpedoes did not span target as greatest lateral space between torpedoes at 1000 yard range was 192 feet (target length 268 feet).

INCLUSURE (A)

U.S.S. GUYARD (SS254) - Report of Sixth War Patrol.

(I) MINE.

A floating object sighted during darkness at 0153 H, August 7, 1944 in position Lat. 6-17 N, Long. 122-37 E resembled a spherical mine with horns. It could have been a contact mine adrift.

On August 15 noted a CM-4 type minelayer maneuvering in vicinity Lat. 01-20 N, Long. 120-49 E. No actual mine laying activities were observed.

(J) ANTI-SUBLANTINE MINE DETONATIONS AND EVASION TACTICS.

The ships in the convoy attacked on July 27 were zig zagging radically but not simultaneously or in the same direction. One would zig right while another would be steady or zigging left.

The activities of sailboats off Stroomen Kaap, Lat. 01-20 N, Long 120-49 E, on August 15 indicate very strongly that these sailboats were placed on the route of Jap shipping to determine if a submarine was present prior to the arrival of shipping in that vicinity.

From the noise heard and maneuvers of a plane sighted after our attack on August 20, there is a possibility that the plane fired an aerial torpedo at the submarine while vevwere at periscope depth.

(K) MAJOR DEFECTS AND DAMAGE.

Torpedoes.

Sixteen Mk 23 and eight Mk 18 torpedoes were loaded for this patrol.

Torpedo troubles other than normal were as follows:

Mark 23

(1) Torpedo #4974 was found to have a leaky starting piston. The air from this leak lifted exhaust valves. It was necessary to manufacture a new starting piston. After six attempts with brass stock and no success a satisfactory starting piston

1/2 MAIN ENGINE.

July 11 - The fresh water pump pressure and the water level in the sight glass of the fresh water expansion tank of 2 Main Engine were noticed to be fluctuating excessively. The engine was stopped and a hydrostatic test applied. An inspection was made through the exhaust port handhole plates. Water was running down the inside of 2 Main Engine. The engine was put out of commission and the liner pulled. A crack was found in the liner at a 3 o'clock position on the liner wall as

inlet seal rings was chewed up badly and water was leaking by. Renewed two seal rings (Dwg. No. N26935 pc 9 part 3236936), all necessary gaskets and reassembled unit. Engine hours 1053.3. July 15 - #12 liner was found to have a crack in the same place as the cracked liner on #2 engine. Renewed liner (Dwg. No. N25035 pc A part 3249346), liner to water inlet seal rings (Dwg. No. N26935 pc 9 part 3236936), and all necessary gaskets. Engine hours 1066.2. Aug. 23 - Pulled #14 liner #4 M.S. to remedy fresh water leak. Renewed liner to water inlet seal rings. Engine hours 1225.4.

This engine was given a complete overhaul by Relief Crew, Subdiv 121 prior to this patrol. All heads, liners and pistons were pulled and inspected. All rings, all connecting bearings, and #8 lower main bearing were renewed and refit.

CCMENTS.

It is recommended that one or the cracked liners be cut in two across the crack to accommodate if there is some restriction in the circulating water space that causes rust to form and clog up the channel completely. Improper cooling and consequently excessive heat at this point seems to be the only logical conclusion that can be drawn as to the cause of cracking in the same relative position of all liners unless the liners themselves are faulty at that point.

It is further recommended that during refit the fresh water cooling system of these engines be completely flushed out, preferably with some rust and grease cutting solvent. At the boats moving around from base to base and using different water it is possible that excessive rusting does occur during periods of idleness and particularly when the systems are drained during refit and allowed to stand idle without flushing.

The number of leaks resulting from twisted and pinched seal rings makes it obvious that greater care should be taken during the installation of liners by refit personnel.

4. Reception: Reception of VIAO was generally good. In the area 9250 gave the best reception. This frequency was blocked by a strong station on the 1600Z sked when in Naro Gulf. Deliberate jamming was noted in this area 1700-1900 Z.
5. Two contact reports were received on the area frequency. Voice signals were received from operating submarines on two occasions.
6. Transmission: No difficulty was experienced in transmitting. On 24 August VIAO relayed our transmission to VIAO.
7. Material: Slight interference from the SJ on VIA-7 receivers.

(M) SD-2 RADAR.

Operation of the SD-2 radar was good for 302 hours of operation. Maximum range obtained was 24 miles. Mile operating the set, all plane contacts were made by radar with the exception of two, at which time the set was being moved 5 seconds per minute.

SJ RADAR.

The SJ operation was good for 620 hours. No ship contacts were made with the SJ radar. These small facts were collected up to 3,000 years. Land piles were received by 160,000 years. On the occasion of this mission the ship was on the second sweep of verification by the ship moving when the piles were not tracked. The land in this case was 12,000 feet high. Numerous piles from atmospherics were observed. At about 1000 miles to the SJ for plane search covering cartridge, 12 aircraft were made although several planes were sighted.

Via: (1) The Commander Submarines, S.WEST FLIGHT.

Subject: U.S.S. GUAMUD (SS-254) - Report of Sixth War Patrol.

1. The sixth war patrol of the U.S.S. GUAMUD was of 60 days duration, 46 of which were spent north of the barrier. While the patrol was well conducted in characteristic aggressive GUAMUD fashion, despite interference from numerous patrol craft and enemy planes, contact with northward torpedo targets was not significantly favorable.

2. GUAMUD fired 14 torpedoes in 12 submerged attacks. Attack #1 was made on a convoy consisting of 3 ships with 4 escorts. Three torpedoes were fired at each of the 3 ships from ranges of 1,500 and 2,120 yards respectively with favorable track and range angles. No hits were made on the first target due either to its shallow draft or chance of course shortly after firing, while the other two ships were torpedoed on the second target. These appeared to be possible low order explosions and no effects were noted on the target before GUAMUD was forced to dive to the second ship. A series of explosions were heard over the target. In attack #2, four torpedoes with possibly originated from the target. In attack #3, four torpedoes were fired at a GUAMUD target. GUAMUD fired four torpedoes in attack #3 on a small 45 second firing on explosion, probably from an aircraft bomb, was felt close aboard and GUAMUD went to deep submergence. Escorts dropped a 15 depth charges.

3. About two hours after the third attack, while GUAMUD was proceeding to 65 feet after a periscope observation, a fast revolver noise was heard to pass over the forward torpedo crew. Upon returning to periscope depth, a plane was sighted circling not far away, landing to the conclusion that an airplane torpedo had been fired at GUAMUD.

Subject: U.S.S. GUAM-D (SS254) - Report of Sixth War Patrol.

4. The GUAM-D is a patrol boat of the U.S.S. GUAM and Submarine Division 12-2 Naval Force within the normal period. During the patrol, GUAM-D operated considerable main and anti-submarine depth charges. Stock of small rings was exhausted and the torpedo manufacturer then from stock of compounded nooprone, type of 45 caliber, it was noted that installing gaskets that they rolled on lip and had no pinched necessitated roll co-rent during rapid or capsize because the process of co-pressing fresh water. The GUAM-D has since practiced the process of co-pressing nooprone of harder, loss-alastic, type 45 diameter and the trouble with impact of gaskets has been evident. It is believed that GUAM-D's crackled liners were due to the gaskets used. The first water cooling system of all four engines will be finished out during patrol.

5. The characteristics of this ship are health of the crew is excellent. Notable is their discipline that disappointed results obtained.

6. The Squadron Commander is pleased to observe the co-operation of Officers, Officers, and Crew back from a long, arduous mission and hopes that better fortune will attend GUAM-D on the next patrol.

Report of 6th War Patrol.

From: The Commander Submarines, SEVENTH FLEET.
To: The Commander in Chief, UNITED STATES FLEET.
Via: The Commander SEVENTH FLEET.

Subject: U.S.S. GURNARD (35254) - Report of Sixth War Patrol - Comment on.

1. GURNARD is Sixth War Patrol was conducted in BANDA, MOLUKKA, CELEBES, SULU, and MINANAO SEAS.

2. Few worthwhile contacts were made although the assigned areas were thoroughly covered. The decrease in the volume of traffic through these formerly productive areas is attributable to the Allied advances westward. Adequate coverage of these areas by submarine patrol continues to be a strategic necessity.

3. One Mark 18 torpedo was badly damaged by a hydrogen explosion while it was loaded in the tube. It was most likely caused by low current in the hydrogen burner circuit. The explosion was not heard, but the pilot light was observed to be out. This casualty re-emphasizes the necessity for accurate adjustment of the current in the hydrogen burner circuit, and prompt withdrawal and inspection of the torpedo when the pilot light is observed not burning.

4. This patrol is designated "successful" for the award of the Submarine Combat Tisqinia.

5. The Force Commander congratulates GURNARD's Commanding Officer, Officers, and Crew on inflicting the following damage on the enemy:

All hands enjoyed the swimming and many new rates and promotions were properly christened. As leaving the Gulf in darkness would prevent firing at the wreck on N.7. Cape, a battlesurface drill was held in the afternoon, firing 13 rounds of 4 inch at 1.5 miles target. Prior to departure, the R.A.A.F. informed us that our I.T.T. equipment had indicated "Emergency" when we entered the Gulf. The emergency switch was checked in the "Off" position, and the equipment seemed to be operating properly. However, the spare transponder was installed as a possible correction. The R.A.A.F. was asked to check us on our way out and make a report if we still indicated "Emergency".

22 October 1944

Searching for Convoy west of ST. STIRUS LIGHT.

0420 SJ radar back in commission but an intermittent short still persists.

0437 Radar contact bearing 110°T. at 14,000 yards. (Ship Contact #3).

0438 Turned to close range as pip is very small and commenced tracking.

0523 Commenced attack from starboard bow with target tracking at 10 knots on a straight course of 2650T.

0543 At 2,700 yards target was identified as a trawler type escort too small for torpedoes, so decided to discontinue attack and continue search for convoy which he might be part of.

0606 Sighted masts and smoke of several ships 12 to 14 miles to northward. (Ship Contact #4).

0608 Submerged as it is getting light fast and we are only five miles from the trawler, who is probably an advance scout.

0634 Basts of at least 15 ships including escorts are visible and there are probably more on the far flank out of sight.

0700 As the range is still pretty great and as we now have only two torpedoes loaded aft, decided that our best chance for success would be to track submerged until we get all tubes loaded, and then make an end around.

2054 Three more shots, not close. 're can't say auch for his shooting but he certainly did his job of keeping us away and scattering the convoy. . . H've lost the element of surprise but we will attempt to open out to the eastward and come in again.

2110 Heading for convoy again with escort still chasing to southward, five miles away.

2143 Radar contact on convoy at 17,000 yards. This is a different group than the previous outfit, indicating convoy has split into two parts. This one seems to be on base course 3200T. at 10 knots. Decided to work around and attack from starboard flank where the visibility is more in our favor.

2202 One escort at 4,900 yards started our way but apparently changed his mind, and we are continuing to pull ahead.

2259 Sighted much signalling between escorts with green blinker lights. Hope we are not the subject of conversation.

2307 The convoy has no apparent organization and is all spread out in separate groups. We are now 11,000 yards on the starboard bow of two medium AK's, the tail end group, who are tracking at 10 knots on course 3400T.

2320 Selected these AK's as targets, and headed in for attack planning to fire three at each.

2338 Both targets are overlapping now at a mean range of 2,600 yards with one escort on this side and a little ahead.

2339 With close to 90 starboard tracks and zero gyros, commenced firing six torpedoes forward using a divergent spread to cover the overlapping targets. During firing the targets were observed to open up fast, so an increased spread was added to the last two torpedoes.

— page 354 —
2343 Targets have turned, either avoiding torpedoes intentionally or by a normal zig, either of which is a big disappointment.

2350 Reversed course to chase again.

2351 After room reported two explosions, probably depth charges by escort.

2353 A heavy pall of black smoke has developed near the firing point, so headed over to investigate. It is probably the escort running around in circles.

2359 Reload completed forward.

Working on Convoy off SINGAPORE.

0016 Closed target and slowed down to watch nim steaming in slow circles, bailing smoke and repeatedly sending AN with his yardarm blinker. He also sends an occasional FU 13, probably his call, and many other unreadable characters.

0030 Escort has headed back towards convoy at 13 knots with us following at 7,500 yards, hoping he'll lead us into a good position.

0100 It are now 6,000 yards behind and he is really pouring on the coal, all we can see is smoke. There are several targets on radar, but all spread out even worse than before. This escort seems to be heading for a nice tar jet, so we will follow and try our luck on the one.

0119 Range to escort is 3,640 yards, and there is a nice Al just beyond him that we will attack.

: escort, henceforth known as Joe, turned left about thirty degrees heaving a parently reached his assigned station, putting us 2,200 yards on his port quarter needing under his stern. Target is at 3,400 yards with another escort on his far bow.

0126
: easing astern of Joe at 1,800 yards making 14 knots and thinking that he must be really blind.

0128
: With range to target of 2,300 yards, commenced firing four tubes forward with a good set up on 1100 port track and zero gyro.

0129
: Completed firing, put Joe astern at 1,400 yards and commenced a hasty retreat.

0130
: Joe is awake now and blinking "a" to which we have no answer. Two explosions at 1:45 and 2:00 after firing were reported from below, but nothing was heard or seen from the bridge, so it looks as though we missed again. There is too little evidence of any damage so none is claimed.

0131
: Joe is apparently satisfied we are not friendly and has turned towards at 2,650 yards firing his gun. Fortunately, his aim is as bad as his vision.

0136
: Heard several depth charges.

0137
: Reload completed forward.

0142
: Lost Joe at 7,200 yards, and secured from battle stations, deciding to call this a bad deal. Convoy is definitely alerted and scattered now, and it just doesn't seem to be our night.

0152
: Hard last of seven explosions, all probably depth charges.

0213
: Set course to return to patrol station off TG. D.T.O., thoroughly disapointed, but we hope wiser for the experience.

0011 Convoy has changed course to the right and now have a thirty or forty portangle on the bow. This u.s.set our plans and was a big disappointment after gaining such good position. It was entirely unexpected as convoy had been tracking steadily on course 3500T. for three hours. Commenced closing the track at standard speed to get in an attack on the last two tankers. The are sure of their speed, and e should get a fair estimate of their course. As ranges will probably not be very accurate, will attempt to fire straight shots on 90 tracks.

0041 ...an attempted ping range failed, so will use generated range. We will have to fire from a position ahead of the flank escort as he is about ahead of the second tanker.

0048 7ith a generator range of 3,500 yards, near 900 port tracks and small gyros, commenced firing six torpedoes forward, three at each of the last two tankers in the column, with the leading one closer.

0050  As we turned to bring stern tubes to bear, sound reported fast screws were bearing 0850 relative. Attempted to get a look, but we ducked on the turn. So, we went down and rigged for depth charges with no hits yet observed. At 31-15' from the first shot one explosion was heard and two more were heard at 41-10' and 41-20'.

0106  As no counter attack developed, and as no screws were audible, started up from 300 feet through a 100 layer.

0121  Broke through the layer at 230 feet after slow progress at 100 turns, and heard one very loud explosion which shook the boat considerably. Started down but stopped at 275 feet and raced up again. As no escort screws were audible and since the two sets of echo ranging from the bearing of the firing point were directed nowhere near us, considered that this explosion was probably the tanker's boilers blowing up.

0125  JT reported considerable disturbance, thought to be breaking up noises.

0152  At periscope depth all that can be seen at firing point is a heavy cloud of dense black smoke covering considerable area.

0200  Smoke is still very heavy and one escort can be seen nearby.

0212  Smoke is beginning to disappear now.

0227  Surfaced with nothing in sight.

0230  Commenced search for convoy.

0257  As convoy is now at least twenty miles away, and as we have only 24 hours to make the 330 miles to our lifesaver station, decided to give up the chase.

TITLECLOSE (A)

— page 372 —
2147 Closed target to 11,300 yards and located one escort between us and target patrolling on target's port side. 'We are right on target's track so decided to open out and come in from the starboard bow where we should have a clear field.

2151 Went to battle stations.

2210 Target has made an unexpected zig which indicates a possible change of base course. We are in good position, but will continue tracking a little longer to check this zig.

2225 Target is now checking on base course 220°T. At same speed and with same zig plan.

2236 We are now in good position on target's starboard bow. As we have no torpedoes forward, and it is too dark for a submarine approach, we will have to head in, swing and fire, and take a chance on being sighted on the turn. It would be handy if we could back in.

2238 Radar has located another escort on the target's starboard side which means we no longer have the clear field we expected.

2242 Both escorts seem to be patrolling back and forth from bow to quarter on each side of target.

2246 Hit good position on the starboard bow, and good information, headed in for attack planning to pass astern of the escort, turn and fire on about an 80 track with 180 gyros when the target is on his far right leg.

2247 Loaded number nine tube to give us a four torpedo salvo. This tube could not be kept loaded due to slow flooding past the outer door, probably from an unsentenced gasket.

2251 The escort is being very accommodating by pulling ahead so we can pass under his stern. At 9,000 yards the target can be clearly identified as a very large tanker.

— page 373 —
2300 The escort looks like a large 20, perhaps one of the now seen defense vessels.

2302 At 3,700 yards the target is zigging right according to schedule.

2303 The escort has reversed course at 2,500 yards acting as though he were suspicious of our presence, but do not believe we have been sighted.

2305 Turned to bring stern tubes to bear before next zig and before we are detected.

2306 Commanded firing aft at 3,000 yards on 115 starboard track with about 25 right gyros.

2307 The escort, now at 2100 yards, turned on his searching light and trained it in our direction for a short period, shortly thereafter the target was seen to turn away.

2310 Nothing has been heard from the torpedoes and the target is still on his way, so it looks as though we missed again. The escort is still playing with his searchlight, but doing nothing else.

2313 Secured from battle stations very disappointed, and changed course to clear the area and head for home with one torpedo left aft.

bearings, radar ranges, plot and TDC. Firing was
commenced when targets were over lapping with torpedoes
spread to cover both. Before firing was completed the
ships opened up and an increased spread was added to the
last torpedo. ... zig away at this
time caused all torpedoes to miss.
This attack was the second attempt at this convoy,
two first having failed when detected by an
escort. The convoy had been tracked all day and
original course and speed were accurately known.
This attack was made after re-contact on the

Type Attack: Right surface attack with bow tubes using TET bearings, radar ranges, plot and TDC. This was the second attack on the convoy of attack No. 1, and was made after following an escort, who stayed behind on the first attack, took to the convoy. The TDC had been tracking this escort, and on shifting to the target the operator failed to reduce the speed. This probably caused torpedoes to miss, although the spread used, other data being correct, would have covered the speed error.

U.S.S. CHAMPION (SS254) - Report of events of 14 November 1944

On 11 November the temperature of 14 unit was found to be 150° low. Investigation found the injector strainer to be carried away. A new injector was installed.

(4) AUXILIARY ENGINE.

On 17 October, on investigating a loud knock in 15 unit, one exhaust valve was found with the head smeared off, the other three valves deformed, and the piston had a hole through the top. A new unit with the exception of the liner was installed.

On 31 October, a submerged log hit the rod motor putting the pit log out of commission. A new rod motor was installed as the old one could not be raised.

(5) TORPEDO.

(a) MRR 23.
On October 20th, torpedo 50216 developed an air leak in the lead from the air flask to the reducing valve which was caused by failure of the soft solder around the threaded joint. Considerable difficulty was encountered in effecting repairs due to lack of testing equipment, but after removing the after body six times and resoldering, the leak was eliminated.

(b) 12-1.
To difficulty whenever was experienced with these torpedoes.

(c) TUBES.

During the first firing of tube 9 on 6 November, the outer door gasket was displaced, causing slow flooding of the tube which was sufficient to prevent keeping this tube loaded. On 6 November, during a surface attack, the tube was loaded ten minutes before firing with no difficulty.

(1) RADIO
(1) RECEPTION.
Rec.ption of schedule was very good with 9250 kcs
being the best frequency north of the barrier. No de-
liberate jamming was observed. The 1800z schedule from
IKN was guarded daily, as was the area frequency of 2830
kcs. While guarding lifesign frequencies, 500, 4475 and
5640 kcs, enemy transmissions were heard, but no jamming
was indicated. Carrier waves only were heard on 4475 kcs.

(2) TRANSMISSION.
On 25 October, when attempting to transmit our serial
T70 on 8470 kcs, a strong station broke in asking for a
repeat of several groups and completely blanked out VHF.
The message was finally cleared on 8290 kcs after a total
of three transmissions.

On 3 November, when attempting to send a message, no
answer to our call up on 12,705, 5470 and 6290 kcs. was re-
ceived from VHF. The message was then transmitted blind
on 8290 kcs with no receipt. Later, received no answer
to a call up on 12,705, two message was again transmitted
blind. This was receipted for by a strong station whose
authenticator did not check. No further attempts were
made to transmit the message.

All other transmissions were cleared with no difficulty.

(3) TACTICAL.
On 9 November, while tuning a broken lead on the
second intermediate amplifier coupling condenser of the
TEL-6 was discovered. This delayed transmission for
four hours.

(4) MISSILE SUILRY.

1. The U.S.S. GURNARD's seventh war patrol conducted in the South China Sea was of forty days duration twenty-eight of which were spent north of the Malay Barrier.

2. Area coverage was good and a special mission was carried out in addition to life guard duties.

3. Contacts were made which resulted in attacks as follows:

Attack No. 1.
This attack made as a second attempt after having been located by escorts on the first try. Six torpedoes in a night surface attack were fired at 2 AKS in a convoy of 15 ships from a range of 2,500 yards. All missed because of a zig away at an inopportune moment.

Attack No. 2.
A medium AK accompanied by two escorts was attacked that same night from a range of 2,300 yards with four torpedoes which missed from control errors.

Attack No. 3.
On 3 November two large AOS were successfully attacked while submerged at night with three torpedoes each at a range of 3,500 yards. Two hits were obtained in one A0 and one hit in the other A0.

Attack No. 4.
A night surface attack with stern tubes on an A0 with four torpedoes at a range of 3,000 yards resulted in misses, probably from course error and excessive range.

Subject: U.S.S. GURNARD (SS254) - Report of Seventh War Patrol.

4. Records of the overhaul of main engines numbers 1 and 4 of U.S.S. GURNARD indicate that these engines were in slightly better than average condition for boats equipped with GM 278A engines. Electrical and auxiliary machinery on this boat were in good condition. Numbers 1 and 2 vapor compressor stills leak and are being repaired. Both vapor compressors require a complete overhaul. The solenoids on numbers 5 and 6 tubes were somewhat sluggish and sticky. TDC is now being tested to determine possible faulty operation and to effect necessary repairs.

5. The Squadron Commander congratulates the Commanding Officer, officers and crew for the aggressive conduct of this patrol and hopes that succeeding patrols will be more productive.

Subject: U.S.S. GURNARD (3S254) - Report of Seventh War Patrol - Comment on.

1. GURNARD's Seventh War Patrol was conducted in the SOUTH CHINA SEA off the west coast of BORNEO. It was the first war patrol for Commander N. D. GAGE, U.S.N., in command of a fleet type submarine. The fine offensive spirit of the new Commanding Officer is apparent throughout the patrol.

2. Four torpedo attacks were made. The first two were on a large SINGAPORE bound convoy with which GURNARD maintained contact for forty four hours. After gaining position ahead during daylight a night surface attack was attempted. On the first try the submarine was sighted by an alert escort at range 7,000 yards and driven off by gunfire. Undaunted, the Commanding Officer headed in again, reaching a good firing position, but all six torpedoes missed two overlapping targets. The final effort was made an hour later. The convoy was completely scattered and alerted, but the radar equipped escorts were successfully avoided and another good attack position gained. Four torpedoes missed again and GURNARD withdrew, since the convoy was within 60 miles of the approaches to SINGAPORE.

3. GURNARD broke her streak of bad luck on her third attack when she sank an unidentified tanker, and damaged another in a night submerged attack following a persistent and determined daylight end-around on a well escorted, plane guarded convoy.

4. On the fourth attack only stern tubes were available. GURNARD was probably sighted as she swung for stern slits, and the target avoided all four torpedoes.

5. GURNARD displayed excellent judgment in the execution of a difficult and hazardous Special Mission.

1156 This escort proved to be part of a convoy, the rest of which were beyond him very close to the coast, and barely discernible against the land background. It was pretty apparent that we were out of luck, but went to 150 feet and ran at high speed to try and close.

1232 The convoy has pulled away steadily at about 14 knots, and only the tops are now visible. From what could be seen the convoy consisted of at least seven marus, with five small escorts, led by one single stack Man O' War believed to be a KATORI Class CL. Two JAKES provided air cover.

1250 Sighted another four engine bomber, with the U.S. insignia plainly visible as he passed at low altitude about two miles away, heading north towards CAMRANH BAY. (A/C #28) This was undoubtedly a U.S.N. PBY reconnaisance plane although the Japs indicated no apparent concern about his presence.

1300 The convoy has now passed out of sight towards CAP PADARAN. Decided against attempting a chase, as the chances were very slim that they would follow any route but the inshore one south to CAP ST. JACQUES. From what we have seen to date, it is apparent that all shipping in this area runs within the close protective custody of the coast, and utilizes air cover from shore based planes. All ship movements appear to be preceded by a concerted A/S search by planes, and the habit of random depth charging by escorts also provides a good indication.

1521 Heard 15 more distant explosions during the next half hour.

1934 Surfaced.

2204 Sent contact report of convoy to BESUGO hoping his pack will be able to get at them if they continue on to SINGAPORE.

10° BLOW SYSTEM.
On 30 December, fuel oil was discovered leaking into 2 turbo blow drain tank, indicating failure of both the chock and hull flapper valves in one or more of the fuel ballast tank 10° blow lines. On inspection of the flapper valves for tanks 3, 4 and 5, the gaskets were found to be rubber instead of neoprene, and were badly deteriorated. Replacement gaskets were made and installed, but as no means was available to properly secure the gaskets in place, the valves were locked shut by using the jacking screw on the operating shaft.

PORT H.P. AIR CONGRESSOR.
On 24 January, a 2" crack was discovered in the 4th stage cooling coil adjacent to the cooler flange, and a new coil was installed.

ENGINEERING.
1. MAIN ENGINES.
The only 2" prior difficulty experienced was the failure of twelve unit injectors on 2 engine and one on 1 engine, all caused by deterioration (rumbling) of the bronze sponge injector filters. In each case, the return side filter was more than half gone, and the small brass particles had worked to prevent the piston into the injector tip. Stack type injector filters were used as replacements to prevent recurrence.

2. AUXILIARY ENGINE.
On 21 December when investigating the cause for excessive use of lub oil, one exhaust valve in #1 unit was found broken and forced through the top of the piston. The other three exhaust valves were badly twisted. Complete new unit was installed.

U.S.S. GURNARD (SS-254) = Report of Eighth War Patrol.
(K) MAJOR DEFECTS AND DAMAGE. (Continued).
ELECTRICAL
(1) I.C. POWER.
On 6 January, while renewing the "V" belts on the speed regulator of J.I.C. motor generator, the contact bar which slides over the commutator was accidentally lifted, causing an opening in the motor field circuit. This caused a sudden overload surge which burned up both I.C. panel line snap switches, resulting in the loss of all I.C. power. Repairs were effected by removing these switches and connecting the panel leads "di rect to the line terminals.

(2) PITOMETER LOG.
During the night of 24 January, the pit log was put out of commission as a result of some submerged object striking the sword arm and bending it sufficiently to prevent raising.

TORPEDOES
(1) MK 42
On 20 December all bow tubes were flooded for about an hour, but the outer doors had not been opened. During the routing that followed, torpedoes #49673 was found with about 7 gallons of water in the afterbody and a flooded gyro port. The afterbody was flushed, and the gyro and port were thoroughly washed, dried and oiled.

During the same routing, reload torpedoes #66023 was found to have a bad air leak in the joint connecting the high pressure air lead to the sea-tray piston. The joint had been cross threaded, but was made tight after straightening the threads with a tap and a die.

On 1 January, a bad leak was discovered in the mid-jet section of the torpedo #5011. The source would not be located, so the afterbody was pulled out and all leads were tightened. The torpedo was installed and charged, and no oil leak occurred.

(2) The torpedo was removed and the afterbody was replaced. The torpedo was then tested and found to be in good condition.

Subject:
U.S.S. GURNAUD (SS254) War Patrol No. Eight, Report of.

1. The eighth war patrol of the GURNAUD was of 53 days duration only 13 of which were submerged and 40 were spent in the assigned areas adjacent to the Malayan and French Indo-China Consuls, Department from Fremantle, Western Australia was made on 1 December 1944 and arrival at the same port occurred on 1 February 1945 upon completion of the patrol.

2. Area coverage was excellent in spite of the reduced visibility pertaining a goodly portion of the time and of the large number of aircraft contacts.

3. Surface ship contacts were at a premium, only three worthwhile ones were encountered and they either could not be closed or else hugged the shore line so closely as to preclude the possibility of torpedo attack. Stronous efforts were made to close to the attack position in each case.

4. GURNAUD is in very good material condition and will be given a normal refit. The general cleanliness of the ship was noted with satisfaction.

5. The Squadron Commander welcomes the Commanding Officer, officers and crew back to this vicinity for a well deserved rest and hopes that the Jcps will present more targets as their desperate situation becomes more acute.

0337 Sent contact report to HAMMERHEAD (to the east of us) on area frequency after having failed to get message off by SJ. The change of bearing of the HAMMERHEAD's SJ interference indicated he had contact, but wanted to be certain.

0400 Determined targets to be on base course 150°T. zigging 25° every six minutes, speed 12. This course will bring them very close to CAPE BANTAN. Visibility which has been poor all day and most of the night has improved. The moon which is almost full is continually going in and out of the scattered clouds and does not set until 0515. Seas are force six, and there is considerable question as to whether torpedoes will run at set depth. In the bright moonlight a submerged periscope attack will be necessary. However, since depth control would be very difficult in the high seas, the direction of which would necessitate heading into them, decided to hold off for a while in hopes of a change to conditions favorable for a surface attack.

It looks as if the men may shortly go behind the clouds and that we can gain position for an attack with a background of rain clouds forming up in the east.

0427 Went to battle stations. Moon has gone behind the clouds and our rain squall is coming into position nicely.

0445 Sent message to HAMMERHEAD we were attacking.

0449 Recived message from HAMMERHEAD that they were attacking, so came around to parallel target's base course at a range of 5500 yards.

0459 HAMMERHEAD now bears 2910T. at 5750 yards, leading target bears 2410T. at 5250 yards. The second target is about 2000 yards behind the first. We were in a much better position than the HAMMERHEAD for an attack on the leading target so decided to head in again hoping that the HAMMERHEAD was making an attack on the after one.

0501 Received message from HUNTER that they were clear.

— page 458 —
0505 Attack No. 1. Fired four torpedoes from the bow tubes at a mean torpedo run of 2200 yards, 105 track and zero gyros with two torpedoes set on six feet and two on four. Target did not appear to know he had been fired at, although wakes of torpedoes running hot, straight and normal could be plainly seen from the bridge.

0507 Set up on second target with stern tubes but in the absence of hits with the excellent set-up of the first salvo decided torpedoes must be running under target in the heavy head-on seas, so did not fire.

0510 Sent results of attack to H.MERHILD. Decided any further attacks on these targets with the sea condition as they are would be a waste of torpedoes, so pulled clear to go around CULI0 REI and conduct a submerged patrol off C.F.E. D.T.N.G.N.

Decided to patrol on the surface about 30 miles northeast of CUL.O RE' along the sea route from the INDO CHINA. to the CHINA. CO.ST for the following reasons:
(a) All latest sightings of Jap shipping by our planes have been along this route.
(b) Will be able to take earlier action on plane sightings during the day.
(c) The great number of sailboats along the coast make it almost impossible to take high periscope observations in the glassy seas without being detected.
(d) Flare report of our last convoy indicated our presence along the coast was probably known.
(e) With the number of submarines to the north and south of us and daily air searches any contacts running along the coast should be reported in time for us to close the coast for interception.

0100 Recieved a garbled plane report on area frequency of a contact bearing 2650T., 50 miles from KIKUIK BAY. Since this is approximately our position assumed plane sighted us. Plane was not seen nor could it be picked up on the SD.

2335 SJ contact bearing 025° relative at 4000 yards. Almost simultaneously with this contact the starboard lookout reported two torpedo wakes along the starboard side coming from aft forward. ...s ship started to swing left with full rudder the port lookout and his relief both saw two more wakes passing along down the port side. (Position: Lat. 15-55 N. Long. 109-32.5 E.) It is impossible to correlate the pip at 025° relative with the torpedo wakes passing from aft forward unless the lookouts could have been mistaken in the direction of movement of the torpedoes.

In maneuvering to avoid the torpedoes the SJ contact was lost. It was again picked up at 6000 yards and tracked out to 6800 yards when it disappeared and could not be regained in spite of closing on the true bearing.

...Although thoroe is some question as to what the lookouts actually saw and the identification of our contact, the possibility of an enemy submarine seems very probable, so decided that shifting our patrol station about 40 miles to the south would be the better part of valor.

Cleared the bridge and was just about to dive when the JCP plane turned away and headed for the horizon. Noticed the LIBRATOR was turning around for another run over us which was probably what scared the visitor. Told the LIBRATOR of our contact and watched him take off in the general direction of the true bearing. However, by this time the JCP had too much of a head start, and he wasn't wasting any time. After about ten minutes of futile chasing the LIBRATOR departed saying he was sorry to have missed our friend.

(J) MINISTERIAL INSTRUCTIONS.
No definite antisubmarine measures were encountered other than the possible torpedo attack on the night of 2 April in Lat. 15-55 N. Long. 109-32.5 E. Occasional flashes of radar interference on the SJ radar similar but not the same as our own indicated the possibility of enemy use of this type radar.

(K) JOB OBJECTS AND DANGER.
FULL
(1) H. CO. AIRCARS.
The fourth stage coolers of both air compressors developed leaks which required replacement of both coil assemblies. Fortunately, these leaks occurred enroute to U.S. and spares were obtained prior to departure from there.

(2) AIR CONDITIONING.
Numerous leaks in the circulating water line to the air conditioning system indicated considerable corrosion in this line which will be replaced during the next overhaul.

(3) SOUND RECORDER.
Hitting the bottom on April 15, 1945 knocked the starboard sound head sheeting out of line causing a leak around the shaft and numerous hydraulic oil line leaks. The valves to the oil lines were secured and taking up on the packing with the shaft rigged halfway in and the sound head kingston closed cut down the leak around the shaft to a trickle at 250 feet depth.

(4) 2 LC ROSTER LCR.
On April 21st wiped after minor boring 2 Low pressure blower. This boiler was replaced with a screw.

FIRST INDORSEMENT to
CO GUINARD's Report of
Ninth War Patrol.

From: The Administrative Commander.
To: The Commander in Chief, United States Fleet.
Via: (1) The Commander Submarine Squadron FOUR.
       (2) The Commander Submarine Force, U.S. PACIFIC FLEET.
       (3) The Commander in Chief, U.S. PACIFIC FLEET.

Subject: U.S.S. GUINARD - Report of Ninth War Patrol; Comments on.

1. The Ninth War Patrol of the U.S.S. GUINARD was conducted in the South China Sea off the coast of French Indo-China during the period 10 March - 9 May 1945. Thirty-eight days were spent in the area, twenty-two submerged.

2. This war patrol was characterized by:

   (a) Secrecy of contacts:
      One contact with two DEs, or other small type, which developed into an unsuccessful torpedo attack; one contact with a hospital ship.

   (b) Many sailboats.
   (c) Few enemy plane contacts and no night planes.
   (d) Sank two floating mines.
   (e) Avoided what was possibly a torpedo attack by an enemy submarine.
   (f) Hit an uncharted pinnacle while running at 100 feet. This ruined the starboard sound head.
   (g) Very little enemy radar activity.

3. The only attack made was on 26 March 1945. Two destroyer escorts or other craft of about that size were picked up by radar and sight at 6800 yards in bright moonlight. A night surface approach and attack was made, speed determined at 12 knots. The attack was with a mean torpedo run of 2200 yards on 105 track, small gyros, depths set 6 feet and 4 feet. Four Mark 14 torpedoes were fired in high power with a total spread of 3 degrees. No hits were made though the torpedoes were observed to run normally. The sea was force six and the Commanding Officer believes that the torpedoes ran under the target. For that reason he broke off the action.

4. The U.S.S. GUINARD returned in reasonably good material condition, clean and ship-shape. She now goes to East Coast Navy Yard overhaul.

5. The Division Commander congratulates the Commanding Officer, Officers and Crew upon the completion of this arduous patrol. It is regretted that the one opportunity to attack the enemy did not succeed.

THIRD REPORT to
GUNARD Report of
Fifth War Patrol.

CONSULATION REPORT TO: 759
U.S.S. GUNARD - FIFTH WAR PATROL.

From: The Commander Submarine Force, Pacific Fleet.
To: The Commander in Chief, United States Fleet.
Via: The Commander in Chief, U.S. Pacific Fleet.

Subject: U.S.S. GUNARD (SS254) - Report of Ninth War Patrol
(10 March to 9 May 1945).

1. The ninth war patrol of the GUNARD, under the command of Lieutenant
Commander G. S. Simmons, III, U. S. Navy, was conducted in the South China Sea
areas. The GUNARD was part of a coordinated attack group along with the U.S.S.
CONFIDENCE and the U.S.S. MANHATTAN, the commanding officer of the CONFIDENCE being
group commander.

2. This patrol was characterized by few contacts, one being developed
into an attack. This attack on two destroyer escorts was unsuccessful due to
erratic torpedo performance in force six sons. The patrol was well conducted and
good area coverage was maintained. The Force Commander hopes the GUNARD will be
favored with better luck next time.

3. Award of Submarine Combat Insignia for this patrol is not authorized.
