HISTORY OF USS HOE (SS 258)

Named for one of the dogfish sharks, the submarine USS HOE participated in eight War Patrols in the Pacific Theatre during World War II, and sank many tons of enemy shipping.

USS HOE was constructed by the Electric Boat Company, Groton, Connecticut. The keel of the submarine was laid on 2 January 1943. She was launched on 17 September 1942, with Miss Helen Hess, an Administrative Assistant in the Office of the Chief of Naval Personnel, Navy Department, serving as sponsor.

The submarine was placed in commission on 16 December 1942, and Commander V. B. McCrea, USN, assumed command as her first commanding officer. HOE operated around New London, Connecticut until May when she got underway for Pearl Harbor.

USS HOE arrived in Pearl Harbor on 15 May 1943, and from the 16th through the 21st, underwent refitting. She commenced her first war patrol on 27 May which continued through 11 July.

Her first stop was at Johnston Island on the 29th, where she remained only a day, and from there proceeded to her assigned operating area. On 15 June, HOE picked up three ships on her assigned operating area. On 15 June, HOE picked up

The third contact consisted of a gunboat, a 5,000 ton cargo ship and two escorts. Due to an unfortunate set of circumstances which included a foggy periscope and a glassy sea, HOB was detected in her approach and forced under by counter measures before an attack could be delivered.

At 0600 on 1 September, HOB picked up two targets at a distance of approximately 22,000 yards. As the targets approached they were identified as a gunboat, a 5,000 ton cargo ship, and two escorts.

HOB raised her periscope for a final bearing at 1800 before firing at the gunboat. She discovered he was swinging to head directly for her, at a distance of 200 yards away. One officer was standing on the wing of the bridge of the ship, and pointed at her periscope. HOB dived deep and on passing 220 feet, the first depth charge went off close aboard knocking paint and cork off bulkheads. The second depth charge was close.

In the meantime, the two small escort vessels took up the attack, and dropped four more depth charges while searching.

At 1405 on 22 September, HOB sighted masts of a large ship on the horizon, and commenced tracking. It was a large tanker, and unescorted. HOB fired a port track straight bow shot at range of 2,200 yards. The boat broached about 20 seconds after ripping its torpedoes. HOB heard two torpedo explosions, and upon regaining periscope depth, she observed the target turning away with a port list. The submarine attempted to overtake the damaged ship, but due to failure of one engine, she was unable to pursue her.

HOB patrolled submerged during daylight, and at 2216 on 30 September, she made radar contact on six ships. She maneuvered on the surface for an attack position while tracking the target to obtain her course and speed. The night was very dark with heavy rain, so the submarine decided to make a surface attack. The group consisted of three large vessels and three escorts. Due to a heavy rain, HOB lost contact. She returned to Pearl Harbor on 18 October via Midway.

The third war patrol of USS HOB extended over a period of 39 days of which twelve were spent in the assigned patrol area between Mindanao and Haimahera. On 16 February 1944, the submarine sighted smoke and commenced tracking. At 1310 HOB sighted the superstructures of a convoy at a distance of 9,000 yards, and headed in for the attack. They were easily visible at this range. HOB fired six bow tubes at the two leading ships, and several minutes later, fired four stern tubes.

She made a total of four hits with her torpedoes. Black smoke commenced pouring from the first two targets, and one large pip disappeared from the radar screen at 6,000 yards. Due to heavy smoke, visibility in the direction of the convoy was poor. At 2354, another pip disappeared from the radar screen. At midnight there were four explosions, and one ship in the convoy blew up, the flames reaching about 2,000 feet.

The force of the explosion shook HOB considerably. HOB passed someone in the water about 200 yards away to the starboard following this, who finished

a light three times. It was assumed to be survivors who were on a raft or in a small boat. The submarine did not stop to investigate as she hurried to close the remainder of the convoy.

Due to the presence of an enemy patrol boat, the submarine fell back 20 miles behind the convoy. HOE picked up a radar contact at a distance of 24,000 yards on 25 February 1944, and maneuvered for an attack position.

When HOE closed the range to about 2,350 yards, one of the three tankers in the group apparently sighted the wake or smoke from HOE's engines and commenced flashing a white light. The leading tanker changed course and opened fire on HOE. Depth charging began at a rapid rate. At 0115, the leading tanker had settled on a course, and HOE fired four stern tubes at her from a range of 2600 yards. There were two hits on the tanker, which stopped her firing.

HOE set her course at 0119 and noticed the damaged tanker was still underway and headed for Banoe Point about 15 miles away. One of the enemy destroyers on HOE's starboard quarter turned and headed for the two tankers at high speed. The DD attempted to pass what he thought was the tanker's stern, and ran into her bows on, causing some damage.

HOE fired her last four torpedoes at the damaged tanker, hitting her with two of them. The tanker sank about 10 seconds after the second torpedo hit, and the remaining destroyer and culler headed up in Davco Gulf at high speed.

The submarine left the area south, heaving expended all her torpedoes, and returned to Fremantle, Australia.

Her fourth war patrol was conducted from 4 April 1944 to 2 June 1944. During this patrol, HOE steamed a total of 12,529 miles, and expended 21 torpedoes in three attacks upon enemy convoys.

Her first submerged attack was made on a large convoy consisting of at least 12 ships accompanied by one carrier and several destroyer escorts. HOE registered two hits on a large cargo ship and a medium oiler. The escorts immediately dropped depth charges over a period of two hours with no results.

HOE changed her course on 4 May and steamed arcuate to the area off the coast of Luzon. She made radar contact on 3 May 1944 with at least five enemy ships at a range of 17,000 yards. It turned out to be a convoy of about 12 ships with many escorts. The convoy changed course at 0455 on this date, and headed directly for HOE. The submarine immediately changed course to head directly for the leading ship in the center column, which was a large transport.

The convoy again changed course which left HOE about 4,000 yards off the track of the port column.

HOE fired four torpedoes at 0509 at a large cargo ship of about 4,000 tons. She then fired two torpedoes at a medium tanker, but was unable to observe hits through her periscope due to depth control difficulties. The escorts commenced depth charging HOE, but fortunately their charges were set shallow and none caused any damage.

5- USS H0E (SS 258)

The first two attacks were night surface attacks on a large convoy of approximately 12 to 14 ships. H0E fired four torpedoes at a large cargo ship from a range of 4,615 yards, and registered two hits. Large and small explosions were heard following this. A few minutes later, she fired three additional torpedoes at another cargo ship from a range of 4,000 yards. One hit was made, and the ship began to smoke.

A long chase was made on the same convoy, followed by a night surface attack with six torpedoes on the last two ships in the convoy. One hit was observed and the target commenced smoking heavily throughout the entire length.

After trailing on the surface, the convoy was again contacted during the night and two more night attacks were made. H0E fired six torpedoes at the two leading cargo ships with one hit. Another approach was made shortly thereafter, firing four additional torpedoes at a large cargo ship. One hit was made and the cargo ship blew up. Another hit was made shortly thereafter when she fired a single torpedo at an escort.

The South China Sea was the area in which the submarine conducted her seventh war patrol as a member of a coordinated search and attack group consisting of BAYI and CAVALLIA. The period of this war patrol was from 23 November 1944 to 3 January 1945.

The submarine made her first attack on 2 December in the Java Sea while enroute to her assigned area. She fired four torpedoes from a range of 2300 yards during a night surface attack on a small tanker, hitting her with two torpedoes. The tanker was damaged as a result of the torpedoes but managed to escape.

H0E's eight war patrol was from 5 February to 8 April 1945 and was conducted in the South China Seas under the command of Lieutenant Commander M. P. Refo, III, USN. Targets were scarce and enemy anti-submarine aircraft measures heavy during this patrol. H0E, in an aggressive night attack on a large tanker escorted by a single destroyer, launched one good hit in the DD which blew her up. USS H0E received the Submarine Combat Ensisignia for this patrol.

She was placed out of commission and in reserve in January 1947. H0E is presently berthed in New London, Connecticut.

USS H0E earned seven Battle Stars on the Asiatic-Pacific Area Service Medal for participation in submarine war patrols:

1. Star/Submarine war patrol 285 -- 27 May - 6 July 1943
2. Star/Submarine war patrol 286 -- 21 August - 18 October 1943

6. In addition to her primary mission of attacking enemy shipping the HOS successfully completed a secondary mission of
reconnoitering which had been assigned her. The results of those are
being forwarded under separate cover.

7. The engine casualty which occurred on #4 main engine before
the HOS over entered her area handcoded that vessel throughout her entire
patrol and in all justice it must be admitted that for once H.O.R. material
could not be blamed. The other troubles with the engines are being taken
up in separate correspondence.

8. Except for the engines the material condition of the HOS
was very good and the health and morale excellent.

9. It is felt that the Commanding Officer, Officers, and Men
of the HOS are to be congratulated for a fine first patrol, and for the
following damage to the enemy.

Subject: U.S.S. HOS (SS258) - Report of First War Patrol - comments on,

1. The first war patrol of the HOS lasted for 45 days. After 15 days in the area and across trade routes adjacent thereto, it was terminated due to the low amount of fuel remaining. This was occasioned by long chases at high speeds attempting to intercept five different reported convoys.

2. This patrol was disappointing in that the area covered proved so very unproductive, only two north while contacts were made and both of these were aggressively pursued and successfully attacked.

3. On the first attack on the night of 15 June it was unfortunate that a large six away by the target forced the Commanding Officer to fire at the unfavorable range of 3,200 yards. The spread used, however, was adequate and had not one torpedo been orrate, two hits should have been obtained instead of one. It is felt that there is a very good possibility that this target sank but since the HOS was forced deep first by a circular running torpedo and second by escort vessels she was unable to obtain definite evidence of sinking and only damage can be assumed.

4. On the second attack on the night of 21 June the poor performance of radar and sound is noted and will be investigated. The shooting on this attack showed accurate control party operation since three of the four torpedoes fired wore hits and in this case there was no possible doubt of the result.

5. Except for the one circular run the torpedo performance was good and an excellent average of 57% hits was made.

U.S.S. HOC (SS258) - Report of First War Patrol.

1. The remarks and summation of damage to the enemy made by the Commander Submarine Division 121 are concurred in.

2. It is noted that intelligent use was made of the Bathymetrograph so that fine trimming of the submarine was possible, thus precluding the necessity of pumping or blowing or changing of speeds to maintain depth control while using evasive tactics.

3. It is regretted that the HOC had to leave her patrol area before the scheduled time due to the high consumption of fuel which precluded additional hunting in the assigned area.

4. A thorough investigation of the engine conditions of this vessel will be made during the refit period and the HOC will be made ready for sea, dependent on receipt of material, as soon as possible. Submarine Squadron Four has been assigned to refit the HOC.

5. The Squadron Commander congratulates the Commanding Officer, Officers, and Crew of the HOC on the results of the damage inflicted on the enemy on her first war patrol.

Subject: U.S.S. HCE (SS258) - Report of First War Patrol.

11 June: 0230(K) Entered area. Set course to make submerged patrol south-east of Anguar Island commencing at dawn.

1326(KI) Sighted small fishing boat.

1926(KI) Surfaced. Petrolied Pelau-New Guinea traffic lanes during night.

12 June: Patrolled, submerged during daylight off Anguar Island and south of Malekel Harbor. Sighted one sampan, one patrol boat and one patrol plane during day. At 1944(KI) surfaced and proceeded to eastern edge of area to intercept convoy reported by GREENLINE. Took station at convoys estimated 1000 position tomorrow.

13 June: Petrolied, submerged during daylight. On obtaining evening fix discovered we had been sent 29 miles to north.

14 June: Petrolied submerged during daylight. At 1014(KI) decided to shift station to a point Courteman miles south. Surfaced. 1103(KI) Submerged. We had just completed our first periscope search at not close. We had just completed our first periscope search at 65 feet and were coming up to 60 feet. Took a quick look around and could see no ship. We had not been sighted on 80 feet. At 1230(KI) started up to 65 feet and on reaching 80 feet heard three other periscope explosions much closer this time. Those explosions were definitely not depth charges so decided they were light aircraft bombs and that we had been spotted from the air while shifting station from 1014 to 1103. Returned to 150 feet, no sound of propellers.

1350(KI) Returned to periscope depth.

1358(KI) Lat. 6°-28 N, L.136-33 E. Sighted ship on port beam angle on the bow 150 stbd. Estimated range 22,000 yds. As a result of previous bombing decided to remain submerged until dark then overtake and make an attack by moonlight. Seas were glassy calm and a daylight periscope attack without detection appeared doubtful.

1908(KI) Surfaced and commenced search at full speed on-time engines, charging on third, fourth out of commission.

2120(KI) Increased speed to full on three engines (17 kts).

2400(KI) Reached point five miles north of ships estimated position and commenced retiring search to south. Frequent rain squalls with a three quarter moon appearing occasionally.

15 June, 013(KI) Lat, 6°32N, 125°45E, Made radar contact. Radar dips indicated one ship with two escorts at 13700 yds. Headed for target at seventeen knots. 0112(KI) Submerged to 35 foot tracking target with radar bearings and ranges. Manuvored for a bow shot. When range had decreased to 5,000 yds subncrged to 63 foot and shortly afterward picked target up through periscope which was an AK of about 6000 tons, 0130(KI) Target made a large sig to his right which left HOE in a position for a storm tube shot at long range, 0138(KI) In position for shot with favorable track and small gyro angles at 31C0 yds, range. Made decision to fire in spite of unfavorable range so fired thrcb torpedoes with 13" divergent spread. One hit. This was believed to be an influence hit as target was unloaded. Time of torpedo run two minutes ten seconds. To more forced down by the of our own torpedoes which ran circular and therefore could not observe final results. Both escorts continued searching and dropping depth charges shortly after torpedo hit. To were not located by the escorts at any time although they searched for about three hours. Target propellers were heard to step when the torpedo hit and were never heard afterward although both escorts could be heard plainly. Cracking noises could be heard in the directi-n of the target for about forty minutes. It scrambled the Chille Muras shown on page 179 of QNI 2038-7. The Commanding Officer feels that bottom results would have been obtained by about one half hours tracking before commencing the approach. To should have come to purpose depth to take a look at target after the attack, however to were in water with a 17 degree negative temperature gradient at the time and its very difficult to break away from heavy density layers without noticing considerable noise which it was desired to avoid during the search. In additi n it was believed the AK sank since both escorts searched for about three hours. Had she been afloat she would have been unguarded during this time when the escorts had no idea of our whereabouts. 0443(KI) Surfaced, notching in sight, light rain, moon had set. Clearred area and charged battery. 0531(KI) Submerged patrold southeast of Anguer Island. 1917(KI) Surfaced. Position doubtful. No fix in over forty eight hours. Stood to eastward at boat speed to overhaul reported convoy. 16 June, 0500(KI) Submerged. 0555(KI) Sighted sampan.

2033(KI) gained position ahead and sighted smoke of convoy. Experienced first erratic operation of radar at this time for the entire cruise. In addition scund gave two bearings that led no to believe I had landed in the middle of the convoy instead of 15,000 yards ahead. 2045(KI) hauled out to clear up the situation and discovered previous sound bearings were the result of some difficulty with own equipment. Radar still failed to respond. 2109(KI) Headed back in to regain sight contact. 2222(KI) In position ahead of convoy. Moon just coming up. 2225(KI) Could not delay submerging any longer although radar had still not obtained contact. Submerged to 35 feet. 2237(KI) Obtained first radar range and bearing at 7000 yards. Gradually submerged the ship down to 63 feet, taking radar ranges and bearings down to 45 feet. 2242(KI) Raised periscope and took first look at the convoy, moon up about three quarters full. The first look disclosed one large loaded AP escorted by two destroyers and one SS vessel astern, of about 1500 tons which appeared to be a small freighter, It looked as though the two had been in a collision. 2257(KI) Lat. 8° - 58 N. lat. 11°-13° E. First four torpedoes from stern tubes at the large AP which resorbed the airfiea near on page 98 of OII 208-J, however it is believed that the target was large,reasons will be given later. Three contact hits were made, first hit one minute forty seconds after firing. The destruction when the second torpedo hit with a torpedo head, was amazing. Flames covering the entire forward middle section shot up as high as the masts lifting large booms at least a hundred feet long and two foot thick with it. The vessel broke into and commenced sinking immediately. Than last observed the bow was floating straight up and down with about 50 yards of open water between it and the stern which was aflame and out of the water at an angle of about 30 degrees. Increased speed to standard for four minutes and changed course 20 degrees while going deep. The Japs dropped two complimentary depth charges, and that was all, although they searched for about five hours. Thirteen heavy explosions occurred on the target in fifteen minutes following the attack accompanied by numerous cracking noises. 'Three was no doubt that she sank. It is felt that she was larger than the airfiea Maru because she filled 5/8 of the periscope field high power at 2300 yards, and in addition, the spread on the three hits at that range amounted to 513 feet.

23 June Patrolled, submerged during daylight, across Empire-Palau
    traffic jakes, On surfacing at night set course to clear
    northwestern part of area as we had a long distance to travel
    to be out by sunset of twenty-fourth in accordance with
    instructions.

24 June Patrolled, submerged during daylight, north of Palau. As a
    result of extensive operations due to increased speed to get
    in area early and attempts to intercept convoys reported from
    contact reports (two successfully, fuel was getting low. In
    addition from dispatches received, believed HDE was still ex-
    pected to complete reconnoitering missions. Departed area.

25 June Approaching Ulithi, remained submerged during daylight. Dis-
    covered on inspection of main engine drive gears one broken
    tooth on main drive gear of #1 engine and large metal flake
    broken off of tooth on #2 engine. The remainder of the gears
    in the train of all engines, except #4, appeared badly worn
    and further serious failures were expected soon. Made decision
    to operate engines on 80-90 combination at all times as this
    was speed at which least vibration developed.

26 June Reconnoitered Ulithi submerged. No activity of any sign ob-
    served. Due to expected failure of main engines at any time
    cancelled further operations and set course for Midway at
    80-90 combination on one engine. Only sufficient fuel remaining
    over our reserve for this speed.

26-28 June Uneventful.

29 June 0825(KI) Radar contact as two planes. Submerged. Remained sub-
    merged until 1800 as we were fifty miles west of Agrilian

II. TRAILER:
With the exception of the first two days, which were fair, the weather off Palau was mostly rainy as many as four rain squalls being in sight at one time. There was no wind and the weather was always calm and glassy smooth making daytime periscope approaches extremely difficult. Sky was generally completely overcast.

III. TIDAL INFORMATION:
Average current east of Palau set 015° True at one knot out as far as 150 miles. However, this was not always true and for a period of sixty hours no current was experienced at all.

IV. NAVIGATIONAL AIDS:
No lights or other navigational aids observed. Much difficulty was experienced in accurately locating the position of the ship while close to the island.

VII. ENEMY ANTI-SUMMARINE MEASURES.

Both ships attacked were heavily escorted, echo ranging used in all cases. There was never any indication that they had picked us up before or after firing. Depth charges dropped were not close. After the first attack escorts searched for about three hours, echo ranging and listening. Following the second attack the search lasted for about eleven hours, however, escorts were far enough away so that echo ranging or propellers could not be heard after four hours. We were 'bombed once about one hundred twenty miles east of Palau while submerged. These bombs were never closer than 300 yds and appeared to be about 50 to 100 lb, bombs.

IX. DESCRIPTION OF ENEMY MINE SURVEYING OPERATIONS.

None observed.

X. MAJOR DEFECTS EXHIBITED.

(a) On 9 June upon attempting to start #4 main engine after surfacing bent the piston rods of #2 and #7 cylinders, the connecting rod, crosshead, crosshead guide and gibe were not carried on board accomplished emergency repairs by isolating #7 cylinder. This casualty attributed to failure of personnel to blow out the engine properly before firing.

(b) On 24 June an inspection of main engine timing gears revealed broken section of tooth of main drive gear #1 main engine. Other teeth in same gear showed abnormal wear after end of tooth near crown. Found metal flack of tooth in crancase #2 main engine. Numerous teeth in the main idler gear of #1 and #3 main engines had linear groove across face of tooth. Condition of gears in #1 and #3 main engines similar in appearance to that prior to replacement of gears at Portsmouth Navy Yard during April 1943.

(c) A squeal developed in the stbd start bearing the second day out of Johnson which remained with us for the entire cruise.

RADIO RECEPTION.

Reception was complete. Interference was encountered on A50-1ks from JNW, Radio Palau, while guarding that frequency on station; and on 12-345 ko and 16-540 from 2GH, an unidentified British station. Signal strength 3 to 5 on station at night. No underwater reception obtained outside 2000 mile circle from Pearl. In general, communications were excellent.

XII SOUND CONDITIONS AND DENSITY LAYERS

Sound reception while on station was good. Density layers were found both on the east and west sides of Palau varying in depth from 150 feet to 300 feet. The checked the bathytomograph on each deep sub-morgance for information of the Diving Officer which enabled him to adjust his trim so that during search following each attack while no were dooy he never had to pump, blow, or increase speed to maintain depth.

XIII HEALTH AND HABITABILITY

Habitability excellent. Health generally good with numerous mild colds which resulted in no sick days. Vitamin tablets were used to cure four cases of rash successfully.

XVII FACTOR OF ENDURANCE CAUSING END OF PATROL

Leak of fuel to continue caused termination of patrol. This was caused by neutral 13 knot speed to area, which was increased to 16 knots en- d by out to get in area as soon as possible, also attempts to intereese two enemy convoy ships two successfully. On day HOE departed area discovered main engine drive gears of three main engines badly worn and under failure was expoted at any time enroute to Midway. The reconnoitering of Pais was cancelled for this reason.

Subject: U.S.S. HOP (SS255) - Report of First War Patrol - comments on.

1. The first war patrol of the HOP lasted for 45 days. After 15 days in the area and except trade routes adjacent thereto, it was terminated due to the low amount of fuel remaining. This was occasioned by long chase at high speeds attempting to intercept five different reported convoys.

2. This patrol was disappointing in that the area covered proved so very unproductive. Only two north latitude convoy routes were made and both of these were aggressively pursued and successfully attacked.

3. On the first attack on the north of 15 June it was unfortunate that a large zig zag convoy by the target forced the Commanding Officer to fire at the unfavorable range of 3,500 yards. This spread was, however, not adequate and had not one torpedo been carried, the hits should have been obtained instead of one. It is felt that three of the four torpedoes fired at the target sank but since the HOP was forced to fire a circular turning torpedo and second by escort vessels she was unable to obtain definite evidence of sinking and only damage can be assumed.

4. On the second attack on the north of 21 June the poor performance of radar and sound is noted and will be investigated. The shooting on this attack showed accurate control party operation since three of the four torpedoes fired were hits and in this case there was no possible doubt of the result.

5. Except for the one circular run the torpedo performance was good and an excellent average of 57% hits was made.

In position to start approach submerged.
Fired four torpedoes from bow tubes at 1500 ton escort vessel.
One hit but failed to explode. A low order detonation was
heard in the forward torpedo room and conning tower. In
addition I observed an area about 15 feet in diameter abaft
the stack and alongside the target, resembling a great amount
of air was bubbling up. Assumed air flask had ruptured with
impact. The target gave no indication that he was aware of
our presence until about forty five seconds after being hit
when he turned away and called crew to battle stations. Four
depth charges were mounted on racks similar to our J-gun.
Astern he was towing something to which was attached, what
appeared to be a rubber covered cable about 3/4" in diameter.
Target turned toward us and we went deep to avoid the expected
depth charging.
Target dropped four depth charges on first run and that was
all. I believe he left about 1050(LM) however we did not come
to periscope depth at this time since escort vessels have been
known to remain silent for some time and then suddenly to re-
sume attack.
Surfaced target not in sight. Estimated escort vessel had
cleared area at high speed and since we did not know course
did not attempt search. My confidence in the torpedoes was
considerably shaken as a result of this encounter. I had made
this approach with great care in maneuvering the ship for a
ninety port track at one thousand yards TDC checked very well
and hits were expected. I intended to fire only three torpedoes,
but changed to four a few minutes before firing to make sure
of a hit.

Target sighted and challenged us at 17,500 yards. Submerged hoping he would think he had a false contact and changed course to 210°true. On first periscope observation discovered a destroyer had headed out our way and preparations were made for attack, however he never came closer than 8,000 yards and then rejoined the formation. With seven feet of periscope out observed one AK and one auxiliary aircraft carrier, also masts of other ships which I believed were destroyers. Continued on course 210°true while tracking targets. Range never closed inside 17,000 yards and at 0630(L) carrier turned southeast, into the wind, and launched planes. Returning to base course about fifteen minutes later target was tracked on base course 190° true speed 15 knots.

0834(L)
Surfaced. Sent contact report and set course for the area. Distance to TDJK was 295 miles which he would reach in twenty hours my speed advantage was three knots and after second would force me to run out about fifty miles to get around convoy. The situation was hopeless and a chase would only result in a useless expenditure of time and fuel. Sent contact report.

L430(K)
Entered Area, submerged for trim dive and training. Sighted smoke bearing 3250 true distant about 25,000 yards. Commenced tracking. Target base course about 1600 true speed 8,5 knots. Sea was glassy calm therefore decided to hold off the attack until about twenty minutes after sunset to avoid chances of periscope sighting. As target approached identified leading ship to be large gunboat of about 400 tons followed by one 500 ton AK with two escort vessels, similar to our SC boats, about 150 yards on beam of the gunboat. The target approached too fast and we were unable to delay approach until after sunset so at 1800(K) commenced attack phase. The periscope kept fogging up which made longer than usual periscope observation necessary to obtain range and angle on bow. At 1810(K) on raising periscope for final bearing before firing at gunboat discovered he was swinging to head directly for us, angle on bow about 20° port, about 200 yards away with one officer standing on the wing of the bridge pointing at the periscope.

2215(K) Range commenced closing and bearing started to draw ahead.
: 2220(K) Changed course to the right to 270°true and at 220(K) lost radar contact at 11,000 yards escort had followed us out about fifty miles.
: 2250(K) Slowed to seven knots while determining action to take. Decided target was only forty five miles from MCLAUGHLIN BANK where he would arrive before I could get ahead of him, likewise on SAITO BANK and GREY FATHER BANK. I did not desire to operate on these banks due to shallown depths, as low as six fathoms, and also due to possibility of mines through which the enemy might have a passage. The ease with which the enemy had detected my presence was very puzzling and after much thought I finally decided that the escorting with their superior speed were stopping to listen frequently while keeping station and that the gunboat with this information had accidently stumbled on a course which made me believe he was equipped with radar, the only reason for him following me out on course 270° true is that he might have sighted my wake although this was hardly possible with visibility conditions and range which did not get under 8,000 yards.

In going ahead full to regain depth control and flooding all variable tanks went to below periscope depth. Heard two torpedo explosions and on regaining periscope depth observed the target turned away with a port list of about ten degrees and down by the stern about six feet. Evident-ly the target had sighted us when we broached and turned away and the last two torpedoes set with a 2½ right divergent spread shift. Target had slowed to about eight knots. Range 3000 yards. Attempted reload forward while closing target and lost depth control again going to 300 feet. About this time heard one heavy interval explosion on target.

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

Radar had difficulty staying on leading target and giving correct information of disposition of ships, first estimate of formation was large ships in line of bearing and second that they were in column. I failed to realize at the time they were zig-zagging as well as plot and TDC operator. A pip would have saved the day. Course was determined as 1400 true, speed 13 knots by plot and TDC. Paralleled convoy course and took station 1300 yards off track on starboard side. Slowed to six knots and circled to right with full rudder while coming to 0800 for 120 starboard track. Then ship had reached course of about 0200 true TDC operator informed me target had gotten by straight shot bearing. He had been watching gyro angles and did not check course. In darkness I could not see target and did not realize error so I gave right full rudder and ordered new course 1400 true while increasing speed to 18 knots. Discovered error shortly afterwards so I stopped and came right to 2000 true for a short tube shot with a sixty track as I did not wish to swing left presenting ships full silhouette to targets. Range failed to close very much and I thought I had gotten too far off track. Actually target had zigged to about course, 1100 true as I found out while tracking later. I decided to fire anyway so I put the torpedoes in low power and at 2300(K) fired at 5700 yards range. One torpedo was a premature and if any of the others hit they were probably duds as the track was then about 90 starboard. Targets passed at 500 yards range with out either of us seeing the other. A light rain had started at time of firing and five minutes later we had a tropical downpour which lasted for about thirty minutes and then slackened to a light rain for the rest of the night. Increased speed to 80-90 combination and commenced tracking to get ahead for a daylight attack.

1 October, 1943.

Ie had lost contact during heavy rain but regained it at 0025(K) and shortly thereafter discovered target group to be zig-zagging and that they had increased target speed to 16 or 17 knots. Attempted to keep range at about 13,000 yards while getting ahead of target group at 80-90 speed combination on four engines. Ie were gaining bearing very slowly but not fast enough to get ahead by dawn. At 0130(K) increased speed to full and at 0148(K) and 0202(K) engine circulating water gaskets failed on #2 and #1 main engines these were both repaired in 29 minutes and 39 minutes respectively and put back on the line, however since they were always falling at full speed did not feel they were reliable above 80-90 combination.

BIGLOSSIE (A)

1. In the meantime we had lost ten degrees in bearing. Continued efforts to get ahead and at 0330(K) with target group still two points forward of the beam and HOD gaining only a degree every ten minutes realized we could not get ahead before daylight at 0530(K), therefore secured from attack and changed course to 2705trme and slowed to 8 knots. None of the targets were ever sighted at any time and their type remained unknown. I probably would have had some success on the first attack if I had gone to the conning tower where I could have observed the radar and TDC and submerged to radar depth when I made the turn to fire. I stayed on the surface to keep the initiative in case I was successful in the first attack the escort would have been unable to keep me down and therefore prevent other attacks.

2. Conducted patrol submerged until 1549(K). Surfaced and commenced search north of EARD, DALHOUSIE BANK.

3. Conducting search on surface as before. Discontinued search nothing sighted. Set course 0875trme.

4. Proceeding to new station east of TRUK. Changed course to 0900trme. Submerged for morning dive. Surfaced, assumed course and speed. Detected radar interference on Sail Dog radar, assumed this to be caused by TINOSA. Interference very strong during morning and decreased to only noticeable amount during remainder of day. Changed course to 1168trme.

5. Experienced same strong radar interference as previous morning. Suspected presence of enemy plane but none sighted. Passed through numerous rain squalls for about one hour and at 0750(K) about five minutes after passing through last rain squall port lookout sighted large reconnaissance plane in the sun heading towards us. Range about four miles. Submerged.

L. RADIO

No defects.

M. RADAR
I. S.D. RADAR

With the exception of one major casualty which was repaired, the SJ radar performed satisfactorily during the entire patrol. One tube, a 63" multi-vibrator tube in the range unit failed during the first two weeks out. This was the only tube failure encountered.

On September 1, the range tank was found to be leaking. This limited accuracy to 10,500 yards. During the following two weeks the tank was filled with water every third day and every effort made to repair the leak. The diluting of the ethylene glycol solution in the range tank did not seriously change the ranging accuracy of the radar. The manufacturers claim a feed change per thousand yards when the liquid is changed to water.

On September 20, the range unit failed completely. Here it was fortunate that a scale was retained that could be mounted on the scope. This arrangement proved to give accuracies to 200 yards on ranges below 10,000 yards. One week of continuous work and trial finally netted gratifying results. The unit was back in operation on September 28. The repairs made consisted of: (a) repairing a crystal connection in the range tank. (b) performing a solution of water and glycerine to replace the glycol solution recommended for this unit. (c) repairing the gasket seals and shaft gland to prevent further leaks.

II. S.D. RADAR

The SD radar did not operate to complete satisfaction during this war patrol. A great part of the blame can be placed on the antenna of the SD radar. Prior to the patrol the results attained were barely fair with the antenna resistance reading about 400000 ohms instead of the 10 or so megohms it should be measured at. With continual submergence and exposure to moist atmosphere the resistance dropped to 20,000 ohms when departing the area.

Subject: U.S.S. HOD (SS258), Report of Second War Patrol - Coronado one.

1. The second war patrol of the U.S.S. HOD covered a period of fifty-eight days thirty-five days over a span in the assigned area. The HOD maintained a submerged patrol for about 60% of the daylight hours while in the area. This is considered excessive and the patrol, therefore, was not conducted as aggressively as it might have been.

2. (a) Only five of the thirty-nine contacts were made; this was more than likely due to the fact that the HOD had no time to search in submerged patrol. The HOD developed three of the five contacts into attacks and one of the attacks made resulted in damage to the convoy. A total of 14 torpedoes were fired and of these, three were hits - two non-misses, and one dual. The percentage of hits was about 21%.

(b) First Contact - This attack on a 1500 ton escort vessel was well conducted, excellent firing position was attained as well as good track and gyro angles (at this time information about 90° tracks had not been made available). It is reported that the one observed hit was a dual as better success was not observed on this approach.

(c) Second Contact - This was not with an AY, an auxiliary aircraft carrier and several destroyer escorts. The HOD was unable to close during daylight hours. The Commanding Officer decided not to attempt an end run during the night due to his small speed advantage and the fact that the targets would reach their supposed destination at Trunk in twenty hours. This decision is believed to have been in error for a reduction of speed by the enemy during the night, prior to entry, would have given the HOD a chance that was worth a try.

(d) Third Contact - This contact consisted of one gunboat, a 5,000 ton AY and two escorts. Due to an unfortunate set of circumstances which included a foggy periscope and a glassy sea, the HOD was detected in her approach and forced under her counter. The HOD was not able to be delivered. In this case an end run was attempted but the target was able to evade under cover of narrow sea squalls.

(21 August to 18 October 1943).

1. The HOB second war patrol was conducted in an area west of Truk and south of Guam.

2. Most of the time spent in the area was utilized in surface running and, thus, good area coverage was obtained.

3. Three aggressive attacks were made, resulting in damage to one tenker. A dud hit, witnessed by the Commanding Officer, allowed another ship to get away.

4. Faulty engine performance was a detriment to the efficiency of this war patrol. The HOB is returning to the navy yard for re-engining.

5. Of note is the fact that one target attacked was towing a cable, which may have been a device for exploding magnetic torpedoes.

6. It is gratifying to note that space time was used profitably in extensive training and subsequent qualification of new personnel.

7. This patrol is not considered successful for Combat Insignia award.

8. The HOB is credited with inflicting the following damage to the enemy:

1210 I Lat. 6°-39' N.
Long. 127°-46.5 E.

Sighted smoke, commenced tracking.

1310 I Changed course to 270° and increased speed to four knots. Sighted tops of convoy.

END OF REPORT (A) -3-

1439 I Identified convoy as consisting of six large Able Kings one large Able Peter, one GI escort, and one small escort. There may have been more small escorts on the far side of the convoy. In addition there was one float plane escort. All perfectly flat sea considered our chances of a successful periscope attack - poor so decision was made to parallel convoy and attack at night.

1917 I Surfaced, commenced running around convoy at three engine speed charging on fourth engine.

2136 I Made radar contact with convoy at 18000 yards, discovered convoy had increased speed from nine to twelve knots.

2200 I Increased to four engine speed in order to get in first attack before moonrise; Convoy was zigzagging thirty degrees to right and left of base course 245.

2303 I With convoy at nine thousand yards, two points abaft port beam headed in for attack; they were easily visible at this range and we expected them to zig towards us. Slowed to 1/3 speed to avoid wake being sighted.

2320 I Set course for 120° starboard track.

2335 I Pired six bow tubes at two leading Able Kings in right hand column, Navrosed course to left.

2336 I Pired four stern tubes at two Able Kings in right hand column, astern of first two targets.

2337 I Four torpedo hits.

2338 I Three explosions recorded as depth charges but may have been torpedo hits as the usual click just before a depth charge explosion was not noticed on these. Hits may have occurred on other than target ships since targets were in line and beyond actual ships fired on.

2339 I Stopped and lay to in order to observe damage, range to convoy 4000 yards, Saw heavy black smoke pouring out entire length of first two targets. Commenced reload both tube nests.

2341 I One escort started closing. One large pip disappeared completely from radar screen at 5,000 yards. Visibility in direction of convoy was poor due to heavy smoke.

ENCLOSURE (A)

— page 67 —
2354 I
Opened range to 8,500 yards on convoy to avoid escort. Another medium pip disappeared completely from the radar screen. Decided to make next attack from port side moon up visibility good. Went to four engine speed course 180°. Checked convoy constantly and always obtained only five pips by radar.

17 February
0000 I Four explosions.
0015 I One ship in convoy was observed to blow up, flame reaching to above cloud level about 2,000 feet and force of explosion shook HOD considerably.
0020 I Passed someone in water about 200 yards to starboard who flashed a white light three times at us. Assumed this to be survivors who were on a raft or in a small boat as we were headed in direction which passed directly over spot first two radar pips disappeared. Did not stop to investigate as we were in a hurry to close convoy.
0025 I Sighted small patrol beat directly ahead at about 8,000 yards. Radar had not picked him up so we stopped and listened. Heard fast propeller beat in direction of patrol boat.
0028 I Changed course to 000° and increased speed to four engines, 80-90 combination.
0035 I Stepped to listen again, patrol boat clearly visible, propeller beat picked up easily by sound, no contact yet by radar.
0038 I Increased speed to four engines 80-90 combination. Changed course to 230 to head for convoy. Patrol boat hauled up to a position on our port bow bearing 300 relative. Range about 8,000 yards.
0050 I Patrol boat was holding position so changed course to 000° to throw him off.
0100 I Changed course back to 270 and observed patrol boat parallel us and haul up on port bow again.
0124 I Patrol boat was apparently faster than HOD and it seemed that he was just holding contact until daylight when we would be forced down. Obviously an attack could not be made with this fellow tagging along. Convoy was now distant twenty miles and we could not get ahead before dawn for an attack. At which time planes from nlp base at DAWO would be out. The problem now was to get away from the patrol boat. Changed course to 000°.

Radar contact 2000 yards. Increased speed to flank while changing course to 102, Could not see anything on bearing of reported contact visibility poor. Radar interference reported immediately with same frequency as our set. Held up firing. Believed this to be one of our submarines making a radar depth approach on us.
: 0336 I Radar p/p had disappeared but interference still apparent. Decided I would let who ever was there have that area so cleared out to east at four engine speed. Evidently this fellow had gotten the drop on us and guns to periscope depth.
: 0614 I Submerged on course 000° to patrol STADE passage. Radar interference still apparent on diving evidently our friend had same idea.

1954 I Changed course to 270°, made ready on four main engines. Decided to approach our friend and identify HOB and plan a search for the night.

: 2018 I Headed directly for contact.

: 2026 I At 5,000 yards range fired recognition flares and stopped. Range commenced opening to westward and at 8,500 yards disappeared. Interference still there, so I assumed he had gone to radar depth. Apparently he felt we were enemy and I was certain he was friendly so I cleared the area at 14 knots. Decided we were getting no place playing tag and that if this continued neither of us would contact the enemy. Discontinued search in this locality and headed back for my own area.

0012 I Three large radar pipe, two smaller ones range 17,050 yards.
: 0045 I Targets visible at 5,000 yards.
: 0053 I Passed directly ahead of leading destroyer at 1700 yards. He was turning slowly right so HOD turned rapidly right also. He ended up in good position for a stern shot on him but held fire since we only had fourteen torpedoes and I wanted to use them all on the three big tankers. Settled on course 0000 with angle on bow leading tanker stern, range 2500 yards. He was crossing ahead of him to get on the other side for the attack.
: 0104 I At range of 2350 yards tanker apparently sighted our wake or smoke from engines as he commenced flashing a white light.
: 0110 I Leading tanker started changing course to his left.
: 0113 I Leading tanker opened fire on us.
: 0114 I Depth charging began at a rapid rate.
: 0115 I Leading tanker had settled on a course so fired four stern tubes at him on a 115 starboard track range 2600 yards. Twenty-three depth charges up to this point.
: 0116 I Cleared bridge of lookouts to avoid injuring too many men in case of hit. OOD remaining on bridge with Captain.
: 0117 I Two hits on tanker, which stopped his firing. So I ordered lookouts back up to the bridge. The depth charging really started. now going off so fast it sounded like popcorn in a hot pan. Forty-nine were counted if that was possible. Kept both escorts astern at about 2000 yards.
: 0119 I Set course 010 and observed that damaged tanker was still underway and headed nearest land BANOS POINT about fifteen miles away. The other two tankers were together and after first changing course to left had changed again back to about 0600. The destroyer on our port quarter was passing up our port side while the one on our starboard quarter had turned around and headed for the two tankers together at high speed. On the PTF we observed this destroyer's pip merge with the leading tankers pip at high speed, at a range of 5000 yards. He was never sighted or picked up again on the radar I-esope or PTF and we assumed that he knowing the two tankers had originally gone left did not know it had again turned back right and in attempting to pass, what he thought was astern, ran into her bows on.

Remaining destroyer joined remaining tanker range 11,000 yards.

: 0236 I
Tanker still afloat, believed there might be a possibility of salvaging him so fired last four torpedoes two hits. He sank about ten seconds after second torpedo hit by sight and radar. The remaining destroyer and tanker headed up in DAVAO GULF at high speed. HOS cleared area to south torpedoes all expended.

: 0315 I
One heavy explosion which shook HOS, estimated to come from damaged tanker now about twenty-two miles distant. Submerged at morning twilight and listened to distant depth charging all forenoon.

J. ANTI-SUBMARINE MEASURES AND EVASION TACTICS.
No anti-submarine measures were encountered on this cruise. New type Japanese destroyers do not have radar, or if they do they don't know how to operate it. Evasion tactics consisted of placing escorts astern and going away at flank speed, stopping and going at slow speed when we thought enemy was listening.

K. MAJOR DEFECTS AND DAMAGE.
None.

L. RADIO.
Messages sent and received with little difficulty at all times.

Following is a description of use of the audio channel of a spare receiver for a modulator:

Realizing the desirability of having available a system of modulating the TEL-6 transmitter used on board this vessel under certain circumstances, a system has been devised using any unused receiver of the RAD-RE series together with other pieces of spare equipment and wire available on board as a modulator.

In the original form, a microphone spare from the LRC equipment was hooked with a piece of shielded single conductor wire to the detector tube by using the shielding as a grounded conductor, this being done by soldering a lug to the shielding and placing this lug under one of the screws holding the main tuning connector shield plate. The inner conductor was soldered to a panel clip, no ordinary grid clip being available, and this clip was simply slipped over the detector tube grid cap. The regeneration control then affords some measure of gain control.

Then from the phone jack on the front panel, a two conductor lead, with jack plug on one end and lugs on the other, was connected to terminals 27 and 28 on the transmitter connection strip. Then, to eliminate any trace of acoustic feedback, a two conductor lead was connected from terminals 7 and 6 of the receiver in use to terminals 35 and 36 on the transmitter connection strip. Since these two terminals are connected internally to the keying relay, whenever the transmitter carrier was placed on the air, the receiver output was immediately shorted out, effectively eliminating the otherwise troublesome feedback. The transmitter test key was used as a push to talk switch.

ENCLOSURE (A) (2L)

1. RADIO (continued)

A number of revisions have since been made to improve the efficiency of the system and the quality of the modulation. First mismatch of circuit impedances resulting from using the low impedance LAD microphone directly connected to the high impedance grid input circuit could be corrected by using either a high impedance microphone or a matching transformer with the LAD microphone. Also, terminals 35 and 36 on the transmitter connection strip are now being utilized in an antenna grounding circuit for receiver protection. This necessitates using an additional relay paralleled to the antenna protection relays to short the receiver output. Also, using a four wire cable rather than a two conductor cable from the microphone (the LAD unit is made with a push to talk switch) and connecting the microphone push-to-talk switch to terminals 25 and 26 on the transmitter connection strip, giving complete control of the transmitter at the microphone. It has been further suggested that the leads from the transmitter be brought out to a permanently mounted jack box mounted on the side of the transmitter.

Use of the above system has been tested on numerous occasions. The revisions were made after an exercise with a patrol plane while working on convoy during training at Pearl Harbor. System was used effectively with escort planes at Midway and while enroute to area. The listening in on a plane spotting for ships firing on Kodiakian at a distance of 750 miles.

2. RADAR

Performance of both sets satisfactory. 3D was secured in enemy areas to prevent DF bearings being taken. The installation of a PTI at Pearl Harbor just before departure was of great benefit.

3. SOUND GEAR AND SOUND MODIFICATIONS

No difficulty was experienced with the sound gear. The JP has slightly greater range than either the JK or 3B and has proved very valuable in locating noise on own ship when running silent.

Sound conditions were generally good in the area.

4. DENSITY LAYERS

Found density layers through area at depths varying from 60 to 200 feet. It was not necessary to use them for escape tactics since all attacks were on the surface at night.

1. HEALTH, FOOD, AND HEALTHCARE
P. HEALTH, FOOD, AND HEALTHCARE
During the patrol run the entire crew was in excellent health both physically and mentally. No sick days for any disease or injury were recorded. All hands responded normally to their duties and to added duties, which required intense strain both physically and mentally over long period of time. The ship is and has been free of all quarter-inteable and communicable diseases.

The food in all respects was exceptionally well prepared, and the diet properly balanced. Fresh fruits and vegetables were available for the first two weeks of the patrol run, and various varieties of canned fruit juices were served each day. Under prevailing conditions of a war patrol the food served aboard this vessel was up to requirements.

Living, bathing and messing facilities aboard this vessel are sufficient and properly taken care of.

Q. PERSONNEL
An additional officer was taken along on this patrol for training to avoid having too many inexperienced officers on next patrol. We were not crowded and he gained much valuable experience as well as an opportunity to thoroughly learn the boat.

Due to the fact that the patrol was very short training could not be developed to as high a state as on previous patrols. The Commanding Officer believes that for this reason transfers should be limited to a low figure in order not to cripple this vessel on next war patrol.

It is felt that an additional allowance of 1 mess attendant to ship complement be added.

Officers and men carried out their duties with efficiency and excellent morale and their performance of duty was very gratifying.

U. REMARKS
The performance of the torpedoes, received from the S/M Base, Pearl Harbor, was exceptionally gratifying. Illnesses were due to control errors and spreads.
While the performance of duty of all officers and men was outstanding, the work of the Executive Officer, Lieutenant J.H. PALMER by his training and coordination of the personnel was greatly responsible for the success of this patrol.
The camouflage paint appeared to be very effective and an asset to any submarine using it.
The efficient operation of the TD by Lieutenant W.P. WILLIS Jr., was very commendable, as well as the assistance of Lieutenant E.F. LANTHROP as COD during surface battle approaches.

EMBOLSURE (A) (27)

13 March 1944.
From: The Commander Task Group SEVENTY ONE POINT THREE.
To: The Commander-in-Chief, UNITED STATES PILOT.
Via: The Commander Submarines, SEVENTH PILOT.
Subject: U.S.S. HOC(85258) - Report of Third War Patrol - contact on.

1. This third war patrol of the U.S.S. HOC, enroute from Pearl Harbor to Frenchk, extended over a period of 39 days, of which 12 were spent in the assigned patrol area between LIND.N.N.O and H.L.H.H.T.U. This aggressive and determined patrol was terminated early due to expenditure of all torpedoes.

2. Successful attacks were delivered upon both convoys contacted. All attacks were night surface actions and enemy countermeasures were rendered ineffective and evaded by skilfully conducted surface actions. In this respect, the commanding officer should note that the enemy's position was not changed.

ATT.CKS 1 and 2
This was a well planned and admirably executed night surface action against a convoy of U.S and L.F, escorted by 1 Cl. and ct. lost one smaller escort. .11 ten tubes were fired, and at least five hits were made. HOC retired on the surface to reload torpedoes and then aggressively came in for another attack upon the enemy. The convoy, but was unable to evade the escort and close the convoy.

ATT.CK 3
This attack upon a convoy of three large tankers escorted by the two destroyers, was nearly frustrated when the HOC was sighted by the leading tanker at a range of about 2300 yards. Despite the fact that he was under gunfire and chase by the escorts, the commanding officer, and with great presence of mind, took advantage of a change of course by the loading tanker which offered a favorable opportunity for hitting, and fired the four star tubes, scouring two hits. After pulling clear on the surface and completing reloads, HOC aggressively returned to the attack.

ATT.CK 4
This attack with 6 torpedoes on one of the two remaining tankers was delivered undetected by the escorts and resulted in three hits. HOC withdrew from the scene, but was not followed by the escort.

1. Forwarded concurring in the remarks contained in the first endorsement.

2. The sinking of the NISHA IAZU and the damaging of the NISHA IAZU, both large tankers, on 25 February, 1944, came at a particularly opportune time following the extensive and successful air strike against IAZU, SIAI, and PAIAT. The aggressive attack on the night of 15 February which resulted in the sinking of two large AKS was well conducted.

3. The radar interference experienced on 22 February was caused by another submarine of this Force patrolling in an adjacent area. Identification on the basis of radar interference alone is not considered a sound practice. Use of pyrotechnic identification signals should be limited to unforseen, or chance, encounters requiring immediate establishment of an friendly nature. The use of any means of identification, flares, rockets, or searchlight should be employed with great caution when in enemy controlled waters.

4. This patrol is considered "successful" for purpose of award of Submarine Combat Insignia.

5. The Commander Submarines, SEVENTH FLEET, congratulates the Commanding Officer, officers and crew on the completion of this aggressive and highly successful patrol. The HUE is credited with inflicting the following damage on the enemy:

Sighted escort carrier astern of convoy at about 10,000 yards on 100 port track.

0509-02 H
Fired torpedoes in tubes no.1,2,3 and 4 at large AK of about 6000 tons at eight second interval with no spread a 107°port track, range 3,600 yards, speed 12.

0509-51 H
Fired torpedoes in tubes no.5 and 6 at medium tanker or engines aft AK of about 4,000 tons at eight second interval with no spread on 37° port track, range 3,100 yards - speed 12. Unable to observe hits through periscope due to depth control difficulties caused by improper operation of poppet valves. This was due to leaking torpedo can injuring his back and causing a last minute shuffling of assignments. One torpedo was heard to explode at 05-11-11 and another at 05-11-11 from times of explosions and plotting it appears that one torpedo hit each target. Due to necessity of flooding negative to keep ship submerged on effort was not made to regain depth control at periscope depth and orders were given to go to 300 feet. He had two destroyers on stbd quarter two on port bow and one on starboard beam at ranges under 1500 yards at firing, Depth charging started three minutes and seven seconds after firing at a high rate. We seemed to have been located almost immediately and our evasion course determined. Fortunately the charges were set shallow and none caused any damage.

END OF DOCUMENT (A)

0703 H
I felt fairly secure under a twelve degree negative gradient. However, the enemy apparently had no difficulty locating HOB and one hour and fifteen minutes after firing he delivered the most accurate attack of all. The total number of depth charges was 56 with from four to six destroyers tracking HOB at various times. The presence of so many escorts (I estimate twelve) pinging and dropping charges drowned out any noises of ships breaking up or explosions from the targets. After the last series of depth charges I went ahead steam-ard to allow a slight sneaking a run on the stub head drop aft. This maneuver was successful and for some uncertainty reason all the destroyers left abruptly.

0703 H Scoured from silent running and depth charge attack.

0736 H At periscope depth and with seven feet of periscope cut sighted one destroyer at the scene of attack apparently stopped. Estimated that he may be picking up survivors, nothing else sighted but one presence of escort carrier believed planes were in vicinity. Sent to 200 feet depth. Listed to pinging for remainder of morning.

1640 H Surfaced and set course for attack position.

1645 H Sighted destroyer hull down out on our last base course apparently searching. Changed course to put him astern and clear area.

1655 H Sighted aircraft on port carrier distant about five miles. Submerged.

1846 H Surfaced.

1958 H Sent HOB serial #3. Hoped 00D might get in an attack. Estimated we had no chance of overhauling convoy before it reached KIAILA. The enemy anti-submarine tactics were the best ever encountered. Demanded searching for reported enemy task force.

9 May Lat. 199-40 N - 109-26 E, Long.

0200 H Commenced running through what appeared to be a whole ocean full of wreckage, overburdened boats, boxes, small kegs, lumber, etc. At the time we were 36 miles northwest from scene of attack however we had experienced a 1 knot north-westerly set during our seven days in this locality and in addition we had not sighted any wreckage before or since until departure 15 May. It is more than likely this was the result of our attack.

Convoy not contacted, changed course to 2000 to cover all possible tracks to south.

: 2300 H
Estimated convoy may have headed direct for LaMira since he could possibly reach entrance LaMira but prior 0600 H so changed course to cover all possible tracks in that direction. He had apparently changed his tactics after torpedo attacks on both proceeding nights. I should have been more careful about this instead of being lulled into a feeling of definitely having him because he had re-peated his daytime tactics.

The first two torpedoes were observed to hit the freighter just behind the escort while the other two torpedoes were not observed to hit. Early due to visibility conditions they obviously from plot must have hit the separate targets at 3000 yards and 3350 yards respectively. Near the bridge, flashes from the last two hits were observed from the bridge. One ship had blown up and another was observed with heavy columns of black smoke pouring out on either length, due to darkness damage to other two ships not observed. Two escorts commenced a hot fire in our general direction. No shell splashes were sighted but some were heard passing overhead and bridge was cleared of lookouts.

Numerous depth charging commenced. The escorts chased us out the furthest we have ever been followed keeping up a continuous fire and we did not get clear of them until they had chased us out about twelve miles.

1. MINES.
No mine laying operations were detected and no mine fields were noticed.

J. ANTI-SUBMARINE DESTROYERS AND EXPLOSIVE TACTICS
The depth charging attack delivered on this vessel on the 6th of May was very accurate. The enemy, however, made the mistake of setting his charges too shallow. HDS was under a twelve degree negative temperature gradient but the enemy experienced no difficulty in locating us and one hour after firing torpedoes delivered his most accurate estimate. He employed both echo-ranging and listening to locate us. In addition they continued searching the area for the remainder of the day using planes and ships.

Evidence of radar interference was detected the morning of 6 May and night of the 25th May.

The enemy is using more planes for searching in South China Seas, Jalu Sea, Celebes Sea, Banda Sea, and Jaluika passage. It is believed these planes employed radar since they seemed to head right in for us. One plane was encountered at night 40 miles north of Cape Bojador, he appeared to be in transit from Formosa to Manila.

K. MAJOR DEFECTS AND DAMAGE
1. Main engine exhaust piping outboard developed several holes this will have to be replaced.

2. The brushes on 2 main engine generator continue to break, in two days constant running since departure Darwin for Frontalie fourteen were broken. The temporary repairs made prior to beginning of this patrol were adequate and generator did not fail us once on numerous chases of the enemy. However I favored it as much as possible and restricted its use until absolutely essential until arrival at Darwin. At this time it was put in use to determine its dependability prior next patrol when the engine will be used all the time. This generator should be replaced during coming refit.

L. RADIO
No defects. All serials were copied and no difficulty was encountered in sending. The enemy employs constant jamming in the South China Sea area and successfully delayed reception of one important message to us for twelve hours. I believe however we would have received this message had it been sent.

- . . . priority:

— page 126 —
3, 10,000 5

Fatal: terminated after retaining five days over time set in operation order. However, it would have been necessary to leave area at that time due to hub oil expenditure, only 50 gal. remaining on arrival. Darwin.

Pool was entirely expended except for two cans of castrup. This was due largely to inexperience of Ceramics Officer and to the many unpalatable items carried.

U. REASONS:

The performance of the torpedoes was excellent except for the one pre-mature which I believe still had the mantis feature in the exploder mechanism, since it exploded after only 250 yards run. The enemy is employing an increasing number of escorts loctain. Some of them cut from the convoy at ranges 6000 to 10,000 yards which makes night attacks more difficult. Evidence of radar was also noted.

Radar contact at 27,000 yards. Damaged course to head for contact at twelve knots. Tracked high speed, but slow given sea after green sea over sand was forced to slow to twelve.

: 0340 H
Tracking of targets gave a base course of 175° true speed ten. We were two points ahead of main target group and with one hour to go before start of morning twilight it was impossible to get ahead of them for attack with heavy sea conditions. Selected target due out ten thousand yards astern of main body which from size of radar pip appeared to be large seaman and was a straggler. Hade approach as fast as possible and at.

: 0432 H
Fiord four torpedoes at a range of 2500 yards, on a 115° port track, straight bow shots, depth setting twelve feet. Could not see target, due to radar range and bearings. We had slowed to 1/3 speed just before shooting and torpedoes were fired from tubes #3, #4, #5, and #6 to give best performance in pursuit heavy sea, a depth setting of twelve feet was used for this sea.

The first torpedo was observed to run in a circle from the track which could be seen out to about 500 yards. The other three ran out straight, I had off making any maneuvers to avoid the circular running torpedo until all torpedoes were fired. Then rang up full speed out the propellers were kicking out of the water and the engines kept tripping out until the overload trip was had! Com manually. We light muffled explosions were heard from the bridge at about this time we started to gain headway, times were not recorded as they were not believed torpedo explosion. A torpedo explosion was heard seven minutes after firing which was without a doubt an one of the run explosion. At the end of firing a strong pungent odor was noticed which had never been experienced on any surface firings before. The problem checked perfectly before and during firings. The only reason for misses that I can see is that the torpedoes ran under the target. Morning twilight had already started and running around those ships only thirty miles off LUXON in daytime after they had already been put on the alert was out of the question, with our two knots speed advantage in the heavy sea. Cleared area to north.

    Target not sighted and search was not heard believed I could have sighted anything at 1000 yards by now in periscope. Radar operator states that on his last observation target ship had appeared fuzzy and he could just get range and bearing. Extincted target was submerged and that he had submerged about 3000 yards. Came to last known base course of target at four knots speed and made periscope observation every five minutes with ten foot of periscope. Out. I did not believe target had sighted us as it was still very dark when we submerged with a light rain, therefore I felt that he was making a routine morning dive or had picked us up by radar.

Lat. 15° 36' N, Long. 115° 39' E.

: 0710 H
    Sighted enemy I - 9 o'clock submarine surfacing about eight thousand yards away on course 090° true. Situation looked hopeless as we had only mark 23 (high speed) torpedoes, however, came to normal approach course and hoped target would zig back which he started to do.

: 0732 H
    Fired six torpedoes at range of 3500 yards, straight bow shot on 120 port track. T.N.O. checked perfectly for one minute before firing and with check bearings during firing before each torpedo was fired. Enemy course 030° true, speed eighteen, after firing was forced to flood negative to maintain depth and periscope was ducked under so that target was not observed. Sound track torpedoes out and spread covered each side of target propellers but no hits were made. 1/2" divergent spread was used which appeared to cover target perfectly. Estimated target sighted torpedo wakes and combed tracks. Five minutes after firing target appeared to be firing torpedoes at us. Went down to 100 foot.

At periscope depth with ten feet of periscope out, target not in sight. Contact was not regained by sight or sound, latter conditions being very poor.

: 1255 H
Sound picked up unusual noise moving at high speed which was attributed to a plane flying low over water. Sound operator had similar actual experience with plane on two previous occasions, noise continued for approximately ten minutes bearing shifting from port to starboard and then gradually disappeared to northwest.

: 1955 H Changed course to 160° true. I believed at this escort had picked us up by sound wake a quick reversal of course would throw him off which apparently it did, as he continued off to north while we closed out at 1/3 speed to south. At this time I decided that we had been detected by radar at CAP CLEAVITE and reported to the convoy as trailing them.
: 1957 H We appeared to be clearing the escort so therefore, commenced altering course in ten degree increments to 220° to make another approach on port side of convoy which was 17,000 yards distant, decided to remain at about this range while running around to prevent escorts taking bearings on our propeller noises.

    ahead but 15 degrees ahead of the line of bearing of the
    other ships so I intended sending in from the beam and pass
    astern of nearest flanking escort. At the same time speed on

0637 H ...another light explosion sounded like a bomb. It were going down on passing seventy-five feet when echo ranging started up from one patrol vessel.

0640 H to 0655 H Received 34 depth charges, they started out at a range of about 3,000 yards and last group of about 20 were dropped at an average range of 500 yards. assumed away had discovered us by some means and was conducting; got search. HOS ordered at 300 feet.

0722 H Sound reported two ships echo ranging assured first patrol vessel had received help from seamen. Closed vents to 3/3 and 3/5 main ballast tanks thinking we may be leaving an oil slick from recently converted tanks. Scored heavy rain squalls occurred during this period so I felt we could successfully pull clear.

0315 H Echo ranging faded out.

0955 H Secured from depth charge attack and silent running, came up to 150 feet. Heavy rain all around on sound gear for remainder of day.

J. ANTI-SUBMARINE SOUNDS AND EXPLOSIVES

Secrets of enemy contact and night of 10 August were definitely redrawn equipment. Their tactics appeared to be to keep themselves between HOD and enemy at the same time, using the enemy away, and firing a few rounds in our general direction. They usually came out rapidly until about five or six thousand yards from enemy and then slowly while keeping their bow always pointed at HOD, as soon as we turned away to commence our approach they rejoined: enemy at high speed. On one occasion HOD struck 1600 yards ahead of loading escort for merciless approach and at night afterwards enemy changed base course away about sixty-five degrees.

During the approach and attack made by HOD on early morning of 20 July, escort apparently wore unaware of our presence until one torpedo exploded at end of run when they dropped a few rounds depth charges.

The depth charge, on 12 August, appeared to be more of an area type. I do not believe escorts had any actual contact after HOD reached 300 feet, although about 20 depth charges were received at a range of about 500 yards.

K. HOD DISPOSAL AND DESTROY

1. C. & R. On July 10, it was found that it was impossible to operate the stern planes by hand. Investigation disengaged that the power clutch would not disengage when the Schneider was deenergized. Since the power clutch and the hand clutch are interlocked, the hand clutch could not be engaged. Disassembly of the mechanism revealed that the spline shifting had been twisted; this really threw approximately four degrees. The clutch coller could not therefore be moved sufficiently along to spline shift to disengage. Shifts force in either direction (32 mm h.r.s.) affected repairs to last the patrol. The spline shift and power clutch coller should be replaced during refit.

The cause of this casualty was bound tentatively traced to malfunction of a switch in the tiller circuit. After the tiller is up to speed this switch is normally closed, thereby shortening the length of the switch. The switch is opened by the switch when the switch is closed, causing the switch to be closed. The switch is opened by the switch when the switch is closed, causing the switch to be opened. The switch is opened by the switch when the switch is closed, causing the switch to be

The convoy had an unescorted escort, radar intercepts, and a submerged approach was attempted. This was also unsuccessful due to the convoy's radar and radar contact. While working around for an hour, the convoy was eliminated by the US radar. The US radar was not able to locate the vessel

    Commanded approach from point bearing twenty degrees forward of beam, leading ship in convoy at 12,000 yards.  He wore excellent tactical in bright moonlight (three quarter moon, no clouds) as convoy commenced to zigzag and near escort hauled out in our direction.  Continued on and finally fired six torpedoes at last two ships in convoy.  Range was excessive and track angle large, however, with escort only two thousand yards away in bright moonlight didn't feel we could do much better.  Obtained one definite timed hit, which was sighted from bridge and possibly two others.  Target on which hit was sighted commenced smoking heavily throughout until length.  HOD retired to south and then west to get in position for trailing, and possible daylight attack.

1944, tide rips were observed inside the 200 meter curve on the east arm side of the pass. (current in the narrows was 6 knots, set 150° T.

2. In the center of the triangle formed by HOSSA BSS, BALL, and LOCK, the current dropped off to 4 knots, set 200° T.

3. In the period between fixes at 163°, 24 September, and 023° E, the current at 2 knots, set 240° T., was observed in the strait northwest of LASS BALL. Let. 5 - 45 S. Long. 110 - 00 E.

(E) NAVIGATION AIMS
No navigational aids were observed. It is suspected that the light-house on HAUCK at 15, in the (A) group (Lat. 9 - 50 N., Long. 121 - 17 E.) has been removed, since radar echoes from the island are weak, fuzzy and can no longer be very short range. This light-house had given very strong radar echoes at 14 miles on four previous times.

... No mines were discovered and no minelaying operations were observed.

(2) HIT-SUIT, U.S.S. "SUNNY," 1944

Similar to previous Anti-Submarine measures, with the addition of night radar planes which were ineffective.

(3) H.MOR DEERTS, U.S.S. "SUNNY," 1944

On 8 October, a preliminary estimate of the casualty occurred. It was stated that the ship was not in a position to attack the submarine.

On 10 October, the casualty again occurred. The running gear on the unit was removed and the engine run only when necessary on 15 cylinders.

On 10 October, a flexible coupling down locking plate on the outer drive disc, a 1/2-inch engine flange, was used. Two outer drive wheels and one top bolt, "generator flange to drive disc" worked loose. A new down locking plate was manufactured and installed, this study replaced the assembly.

This casualty is attributed to excessive vibration of the generator unit at all speeds. (The commutator on the generator has been out of range since 31 March 1944. A cut was taken on the commutator in June, 1944, with no improvement in performance.)

On 8 October, the gyro spindle was bent on #2 Torpedo Tube, due to faulty operation of the gyro spindle retraction mechanism.

This failure is attributed to excessive wear of the locking tow on the clutch and the throw out pin. This condition exists on tubes #1 and #4 also.

25 H.C.
On 7 October, the cable between the Conning Tower and Control Room units of the 25 H.C. flooded, making this equipment completely inoperative. To repair the damage it was necessary to loosen the packing rings and pull cable through until a good section of cable was exposed to sea. While doing this, it was found that in the original installation, too much slack had been left outside the pressure hull. This had partially cracked the cable to wash around in the superstructure, causing the cable sheath to fail.

(1) RADIO
Radio reception was very good on this patrol. VFO box schedules were received well on all frequencies, particularly 9250 Kcs. In past patrols, in this area, it was often necessary to get fox schedules from VFO. Because of failure of VFO, on this patrol this was never necessary. Japanese blocking was relatively ineffective.

The voice circuit (2500 Hz) proved efficient when operated at 1000 kilowatts, pilot volts, etc. The radio circuits on the 25 H.C. were better than the 25 H.C. circuits on the 25 H.C.

(1) Radar Control.

The other two cases these boats involved the on-time multivitrator tube in the medium range. It has been our experience that stable operation can be obtained only when an R.O. 657T tube is used, although there is no reason for this. With any other manufacturer 657T, however, the equipments use unstable, usually giving excessive temperature plate current. One other casualty occurred which, however, was serious enough to require action. It was found that the tube was in the PPI was microprocessor, the trouble occurred only on extreme vibration; so the tube was not replaced.

For typical range for this patrol are listed in the table below:

| Type of Tube | Range (Nautical Miles) |
|||
| Jop Herold Six  | 52,000 yds.            |
| Convoy          | 27,000 yds.            |
| Unidentified large vessel | 45,000 yds. |
| ARO ISLAND Light | 32,000 yds. |
| Patrol boats, etc | 3,800 to 9,000 yds |

On several occasions unusual ranges were obtained which are believed to be due to "torpedo". In the PPI range, an object not land - was picked up to seaward at an estimated range of 71 miles. Land courses were obtained at about 22 miles. At 1500 yds. the torpedo was apparently accurate frequently - about 20,000 yds. The submarine was picked up at 23,000 yds.

Comments on.

1. The sixth war patrol of the U.S.S. HON was conducted off the west coast of Luzon during the period 15 September to 22 October 1944. It was a thirty-seven days' duration with twenty-four days spent in the area. Twenty-three days were spent at anchor. The Commander Commander U.S.S. HON was in command of a corvette attack group consisting of the HON, C.BRITISH and ASFRO.

2. Five nights' surface attacks were made and twenty-four torpedoes were fired at an average range at a range of 4,505 yards. The depth of the attack was 4,615 yards and the time of the attack was 1 hour, twenty-four minutes later. The attack was successful.

Attack No. 1: Following a long chase and round the sea, the submarine was in the vicinity of a convoy of ships. The submarine was in the area at a range of 4,505 yards. The submarine was in the area at a range of 4,515 yards. The submarine was in the area at a range of 4,575 yards. The submarine was in the area at a range of 4,

1. HOB's Sixth War Patrol was conducted in a
Coordinated Search and Attack Group with ASPRO and QABRILLA off
the Northwest Coast of JUZON. HOB's Commander: Cricior, Commander
V. B. NOOREA, USS the Group Commander.

2. Five night surface attacks were made on a large
northbound convoy on two successively nights. Two long range
attacks were made the first night, resulting in sinking one large
AK and damaging two medium AK's. HOB submerged during the day, but
regained contact that night due to the excellent information
supplied by ASPRO who had maintained contact throughout the day
although all torpedoes had been expended. In two other long range
night attacks HOB sank another large AK, and damaged one unidentified
fled AK and one escort vessel. Soon after the last attack HOB
contacted a submarine from TASK FORCE 17 by 5J radar and turned
the remnants of the convoy over to them.

3. When the commutator of No. 4 main generator ar-
mature was disassembled the commutator bars were found to be crack
ed, due to excessive tension on the commutator retaining studs
which hold the retaining ring in the Vee-slots on the end of the
commutator bars. This is a design weakness that was also dis-
covered in a spare Allis-Chalmers armature at Navy Yard Mare Islar
Replacement armatures are being procured by Bureau of Ships for
installation during the next Navy Yard Overhaul period of ships
having this type of generator.

The award of the Submarine Combat Insignia is
authorized for this patrol.

Took to full speed on 4 cylinders constant helm zig. Still light. Spent rest of night fish tailing through swell native craft. To contact over 400 bts from a two man canoe to a full size 40 bts. Lost. Passed them 500 to 2000 yards ahead. The fisherman showed a lot of curiosity in the HOR. Radar generally picked up those boats he traced 2500 and 6,000 yards, descending on tachter they had sail set or not.

Radar contact, 016° T, 9,300 yards. Went to battle stations. HP gets strength five on 65 megacycles. Started to key SD but decided just to slow to 1/3. Air reports very loud, all around the dial. Something peculiar about this. Heir ator

save probably St. Louis P. Piro. Looked at A. and S. antenna and both were floating brightly. Determined this target to be another s.s. ship, then two other radar contact, then another, finally we have another fishing fleet. S. is really picking up.

0556 All stop. Changed course to 2050 T. Put down sound head, listened. No contact. Took single ping, searching 20 fathoms. Put on course back on course went ahead full on three engines.

0423 Radar contact 15,500 yards, bearing 3210 T. Let, 0634 S. Long, 111 50 m. Ship contact 15,500 T. To be sure inshore of him. Source charge. Put 4 engines on propulsion, ahead 1/3. T. 2000 says he is on course 150 T, speed 9 kts. Course right to 3250 T and list the target by 5 degrees.

0426 Contact 220 rate, range 5050 yds. Maybe an escort, but I think not, too far from target. He circled him and he is riding six kts. and a. out. Same course as last. (though check).

0425 Target in sight a. out 9,000 yds. Looks small but very indistinct in distance.

0441 TDD now says so. Check on 10,5 kts. course 1300 T. Don't think he is sighted. Decide to fire 4 torpedoes. Set depth 6 feet. All aboard. Searing on first way, and fire both to hit, one close ahead on last two torpedoes. Still cannot make out target for sure. Judge hit to be about 240 ft. long, about 1500 tons. Looks like a small unloaded tanker. Ship has boat-like, dump construction look, straight lines and right angles.

0445 Steady on 0150 T.

0445-3rd First at tube.

0445-4th First 2 tube.

0445-12 First 4 tube.

Conducted firing with gyro 12 right, torpedo run 2300 yds. Target course 1300 T, first speed 10,5 kts. track 700 starboard.

0445-30 Left full rudder all ahead flank. Let's check our so called sail boat. H. opened range to 3500 yds. on target. Sail boat stall also alike a sail boat according to IDC.

...I torpedo hit just forward of the bridge and #2 beneath this bridge. Hot much splash hits picked up. SU says range of splash #1 50 yds less than range on target. Target scored to take a list to starboard and slow to 6 knots (according to TDC), but he certainly did not look like he was sinking or he quickly risked. Had expected to see him break in three pieces.

DOCUMENT 2 (Cont'd)
Commanded firing with gyros 20 left, torpedo run 3700 yds. track 100, all tubes fired by held searing method from bridge. Torpedoes running hot, strutight, and normal. Target sighted torpedoes and avoided. He has seen us all the time I can sure. Radio says he has not squeaked for help yet, that they know of. On sea three seiblots so decided to pull clear as I do not care to dive in 12 fathoms of water 50 miles from SCOTLAND. Decided to fire these last three torpedoes at 1000 track only because he would be our last chance at this target. Soren torpedoes at a 1500 ton merchant man and no apparent danger. Ordered out on ore 3200 T at flank speed on 4 canoes.

1520 left target on radar 2000 ft, 10,800 yds. Can just rake out a 5 a.s.l. boat, 700 aces in course north, speed 6 kts. pretty fast seiblots, but I am sure he is a seiblot.

1553 Lost both new seiblot and our torpedo target on radar, wore seiblots, he ran going to have to dive.

1540 Now in 20 fathoms of water. Diving officer cannot get the boat down. Executive officer took the dive and we finally got under. Nautives are again curious and load over to have a look, I suspect.

0555 Yes, here is a seiling cargo about 700 yds. away headed for us. Pulled the scape down and ran over it to get off his track, went to standard speed. Sl hears noises, then he hears piping. Coming over sound ran not excited. He reports all clear.

0623 Stopped to 1/3 and decided to run on 2700 T until 0600 since he was us leave on 3200 T. Scoured from battle stations.

0600 Changed course to 3200 T. Seiblots in sight all day.

0725 Asked again. for P.DDLL's position since P.DLL does not answer.

0745 Abort. sent position of P.DDLL's contact.

0746 Received P.DDLL 1-0-2 (Chu, 1g, one escort). C/O ttl 1400 T.

0747 Received P.DDLL's do. 14, leaving his position. Northeast of us.

0803 Received recognition signals with P.DDLL via S.O.

0810 Received P.DDLL's 1-0-3, now we have seen definite do.

0820 Received P.DDLL's 1-0-4. P.DDLL is attacking.

1007 C/O to 270° T.

— page 231 —
1015
Took a look. Everything fine. Target has ten starboard angle on bow. One escort on his starboard quarter about 1500 yds and one on his port bow. Cannot see escorts except for their masts. Target identified as SHINONI H-3 (page 275 OIL 208-1). He is light, back gives draft light as all fit. Set all torpedoes on six ft. (Litter develops should this be fit, would have been better). Seas very heavy from 020° T. Depth control will be the bigest problem in this approach.

1019
Took ready all tubes. Look shows near escort three degree port angle on the bow. Target four starboard angle on bow. 20th escorts pinning. Near escort bounced one off our port beam.

1033
Left full rudder. Will come to 220° T and shoot in next look. This will make it hard on the driving officer, but cannot help it.

1034
Steady on. Cannot see either escorts and only mast bridge and sterns of escort. Had intended for shoot four bow tubes, but an attack of our escort now. Sound says he is bouncing his pins off us. It will have to shoot before we lose depth control intercept.

Fulled clear on course 270° T. About 40 percent of the 40 mm hit the targets and about 60 percent of the three inch shells were hits. Set fire to buildings on north end of island, but [STOP: text here] to knock down radio mast or set fire to tanks. Then soon put out the fire on north radio station. Planted to put pretty ashore total hit and burn the place down. No gun fire of any sort replied to our shelling so I think there are only a few radicrons and we cover exports left on the island.

Then I reached the bridge secure the engine and the charge and maneuvered on the battery to pick up the men. Could hear Burdens yelling above the wind and told him to pile down and take it easy. Hlinked a red flashlight at him to reassure him. Durins caught the life ring thrown to him and with the help of Jaunzahn, who dove overboard from the main deck aft, was able to raise the ship.

Aurbina as he was too weak to walk alone when he was taken

of Rauzenhin for drink, orders, injuries, etc. His
was a courageous but foolish act, I did not even know two

(P) HEAVY, FOOD, AND HEALTH

The general health of the crew has been excellent. Mild upper respiratory infections were prevalent as before during the first three weeks of the patrol. One case of O-1-trichl fever was reported on the sick list for two days during the third week and the same patient was re-chrined with tonsillitis some during the last three days of patrol. He will be transferred to the tender for further treatment. No other illness or injuries occurred throughout the patrol.

The food was good and prepared, as it is daily and sufficient in quantity.

Living conditions have been very satisfactory. A married nurse of recent birth is now stationed during the last two weeks of patrol. Participation in necessary during this period.

1. The Seventh War Patrol of the HOB was conducted in the SOUTH CHINA SEA as a member of a coordinated search and attack group consisting of TAC, B-24, and CAVALIA.

2. The first attack was made on 2 December in the JAYA - SIA while enroute to assigned area. Four torpedoes were fired from a range of 2300 yards during a night surface attack on a small unloaded tanker, and two hits damaged the target. The target continued on at ten knots and HOB followed into twelve fathoms of water where three more torpedoes were fired, but none hit. The second attack was made submerged on a large 6.0 with two escorts from a range of 1500 yards. Seas were heavy and depth control difficult. Three torpedoes were fired but no hits were observed.

3. During a considerable part of this patrol the HOB was assigned reconnaissance duty in connection with PHILIPPI ISLANDS operations.

4. The award of the Submarine Combat Insignia is not authorized for this patrol.

5. The Force Commander complies with the Commanding Officer, Officers and Crew of the 1C2C to the reconnaissance duty performed on this patrol and upon inflicting the following damage upon the enemy:

    Freight a plane's belly tank alongside. Tank was about 1/5
    full of gas. Could not get it into air. It is definitely
    not a U. S. plane's tank however. Sank it. Lots of
    debris in the water looks like it came from task force that
    radioed Signal last January.

2100
    Sort HX. 15 to GUADALCANAL also all planes contacts of any
    possible use. GUADALCANAL is a ship to patrol off GUADALCANAL

U.S.S. HOB - EIGHTH 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. HOB (SS628) - Report of Eighth War Patrol
(8 February to 8 April 1945).

1. The eighth war patrol of the HOB, under the command of Lieutenant Commander H. P. Refo, III, U.S. Navy, was conducted in the South China Seas.

2. Targets were scarce and enemy anti-submarine aircraft measures heavy during this patrol. The HOB, in an aggressive night attack on a large tanker escorted by what was estimated to be a TERRITORY Type destroyer, got one good hit in the destroyer and saw her blow up. This thorough, aggressive patrol adds another splendid performance to the long, fine combat record of the HOB.

3. Award of Submarine Combat Insignia for this patrol is authorized.

4. The Commander Submarine Force, Pacific Fleet, congratulates the coordinating officer, officers, and crew for another successful patrol and for inflicting the following damage upon the enemy:

SUNK

1 - DD (TERRITORY TYPE) (EU) - 2,300 tons* (Attack No. 1)

*NOTE: Since the above damage was done in areas under the operational control of Commander Task Force SEVENTY-ONE, he is requested to assume credit accordingly.
