1. The attack on the convoy was well planned. The decision of the Commanding Officer to attack prior to dawn is concurred in. The loss of depth control at the crucial moment is blamed on the previous five hours' training and prevented attack as planned.

2. An accurate reconstruction of events leading up to the collision is impossible, but from all information it is clear that a combination of poor sound conditions, redacting enemy measures, and lack of periscope information all were contributing factors.

3. During darkness it is not possible to swing the periscope around rapidly to locate all ships in the vicinity. If the observations by periscope are further handicapped by poor depth control, the safety of the submarine against remaining at a distance of 100 yards from the target sound reports, while it is expected that sound operators will be always alert to picking up and reporting new targets, it is felt that he should be informed when other sources of information such as radar or periscope are not available to the Commanding Officer.

4. An immediate warning of new propellor noises under these conditions might have been of value to the Commanding Officer in avoiding collision.

1542 (L) Submerged to conduct approach. Went to battle stations.
1545 (L) Picked up target bearing 359°T range 10000 yards. Secured from battle stations. Vessel was a U.S. submarine prob-bly the LOCKWILDER. Took three pictures at 7000 yards. Submarine had evidently made a routine dive between 1542 and 1645. Course about 100°T and surface speed 12 kts.
1707 (L) Abandoned approach and continued toward area.
1616 (L) Surface.
October 18
Generator engine lub oil pressure is getting dangerously low.
1026 (K) Lub oil supply line to starboard reduction gear carried away. Ransval of perts accomplished at 1400.
1920 (K) Rader contact, 1617°T distance 15500 yards. Connected trc.king. Convoy appeared to consist of three fairly large ships and four small ones some of which were probably escorts. Base course was 345°T, speed 11 kts.
2231 (K) Submerged.
2339 (K) Fired four bow torpedoes, three at right flank ship (about 6,500 ton .K) and one at overlapping ships in fr column. Sent 6cop and rigged for silent running since right flank escort was bearing 270 relative, distance -out 400 yards, with 0° angle on the bow. .it 7140" and 7147" heard two explosions which sounded like torpedo hits. It is believed that two hits were obtained in the left flank ship (about 7500 ton transport). The torpedo run to this target would have been about 5800 yards.
Sloven depth charges were dropped between 2356 and 0000. All appeared to be distant. Sound heard a high noise low-l in the general direction of the probable hits.

2. Left the scene to continue patrol.

3. Sighted tops of two battleships, contact #2, bearing 265°T distance 25000 yards with angle on the bow 70° port. Came to course 065°T and shifted to four engines spaced to open r-nge. Under the conditions then existing, to dive would have put us about 25000 yards of the track. Hoped to make an end round and tried to open the range to avoid being sighted.

4. Leading battleship bearing 256°T r-nge over 31500 yards (radar had a short time before, obtained a range of 31500). During this period angles on the bow appeared to vary from 70° port to 45° port giving a base course around 135-145°T, speed 17 knots.

5. Came to 000°T, targets were getting more distant but during this period two observ- tions gave 20° sternboard angles indicating base course about 115°T.

0856 (K) Bearing of a ship was 263°T. At the time it was thought it was the leading bettleship which indicated a zig in base course to their left but at
0905 (K) there was no doubt that it was a destroyer about 12000 yards distant with a 0° on the bow. There is no doubt that our smoke (a light brown) had been the excuse of our being sighted.
0906 (K) Submerged and came to 257°T. It this time there was considerable doubt as to which way the target had gone.
0925 (K) Sighted RUSARU elss destroyer bearing 234°T distance 11000 yards angle on the bow 120 port (it is interesting to note that the newly installed scni listening gear - JP equipment was the only one which herr chn). From this set-up it was believed that the formation had radically zigged to their right and sent the destroyer over to keep us down. Prepared a contact report and surfaced at
1113 (K) sent the message and at
1147 (K) rider contact on plan at 14 miles, plane contact #1. Submerged. Had sent the report out blind before submerging and were about to make a second transmission. Rotating torpedoes and at

    Changed course to 300°T and slowed to 7 knots. With visibility practically unlimited except for foggy spells, believe smoke was unusual for formation or close to high speed vessel which had disappeared before we could close for sight contact.

0650 (K) Sighted smoke bearing 270°T distance about 13 miles contact. Came to course 140°T at four engine speed to get around and ahead of target.

: 0720 (K) Target appeared to be heading towards us so submerged and headed towards. Unfortunately this was a snap zig and we were then left about 17000 yards off the track of his later - determined base course of 140°T. Decided to look convoy over without attempting long range shots and catching them later in the day. Came to normal approach course 4 kts speed.

: 0910 (K) Took pictures of enemy which consisted of a small cable with funnel at about 500 tons.

: 1820 (K) Ahead of target. Decided to make a nite surface attack after moon set. Although target was small it was felt that it was worth a try of expenditures of three torpedoes. At

: 2204 (K) fired three torpedoes, 110° starboard track, range 3400 yards, bow tubes, depth 8 ft. All missed. Turned away at high speed. Target did not zig. At 6 and 9 minutes after firing, two exploding sounds were heard which were very likely the torpedoes exploding at the end of run. Ratired from area. Did not consider target worthy of more torpedoes. 'ith swell running did not believe torpedoes could successfully be set for lesser depth.

0454 (K) Came to 150°T, 15 Kts.
0544 (K) Came to 060° to open range since dawn was breaking target bearing about 230°T 10 miles. Target had shown a dim white light at intervals.
0558 (K) Changed course to 140°T.
0306 (K) Sighted ship (contact #5) bearing 136°T distance 7 miles, angle on bow about 10 port. Submerged and came to 090°T.
0616 (K) Target appeared to be PC boat type and appeared to have an aircraft search radar on the foremast. Target kept pinging on 20-22 Kcs, was on course 320°T at 15.5 Kts (260 RFI).
0549 (K) Took pictures at about 4000 yards range.
0555 (K) Changed course to 150° to close track of ship previously sighted. Believed this PC boat to be a rolling escort.

Two very small boats had silhouettes similar to some of our lightships. There were no targets worthy of torpedo fire - and the escort looked too good to attempt gun engagement. Convoy was on base course 150°T, making about 4.5 knots good. Abandoned prop. knots good.

1. SAURY was patrol number eight extended over a period of fifty-three days, twenty-nine of which were spent in the patrol area. Patrol was terminated by operation order.

2. Only four sight contacts were made on this patrol among islands to westward and northwestward of THUK. One radar contact indicating passage of large men-of-war at high speed was made on 1 November but SAURY was unable to close. A sight contact on two (2) zig-zagging battleships at 0749 on 19 October at 12 miles caused SAURY to take an intercepting course at high speed on surface. This attempt at an end around was frustrated by the approach of an enemy destroyer. The destroyer was probably a roving outer screen but its presence caused SAURY to dive. Keen disappointment was felt when enemy formation was estimated, although not seen, to pass near submarine position when originally sighted.

3. SAURY was able to close to firing range for two attacks.

(a) At 2329, 16 October, in bright moonlight, a seven ship convoy consisting of 2 AKTs, 1 AP in line of bearing, and 4 smaller ships around the formation of about 1500 tons, at least one of which was an escort, were attacked submerged using radar and

U.S.S.S. SAURY - 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. SAURY (SS118) - Report of Eighth War Patrol.
(4 October to 26 November 1943).

1. The eighth war patrol of the S.S.SURY was conducted in the area around the islands north and west of Truk.

2. As much surfacing cruising was resorted to, the area covered was good. Only four contests worthy of torpedoes were made, and of these, two of combatent ships were not closed due to the high speed of the targets. The two attacks made were a progressively conducted but because of insufficient evidence no damage can be credited.

3. It is noted that the smoking of the S.SURY's engines probably caused her being sighted on an attempted end around run on the enemy battleship task force on October 19, 1943.

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

1634 (I) Sighted masts and upper bridge structure of destroyer bearing 030° T, range about 25,000 yards. May have been sighted at this point. Visibility was very peculiar - we would sight a destroyer and then suddenly it would disappear. The horizon had a glare to it similar to the heat effect on a paved road. At this time it appeared that the two destroyers had slowed to about 8-9 knots to interfere with either GUDD3CN or us. Opened to westward. 1646 (I) Chenged course to 300° T. 1733 (I) Chenged course to 000° T. 1739 (I) Heard several more depth charges. 1850 (I) SJ radar contact 074° T, distance 24,500 yards - good sized ship which may have been false contact since we lost it in about two minutes. 1854 (I) Chenged course to 345° T, to gain in bearing. 1943 (I) Heard about six depth charges and saw flashes probably from three or four ships. 1945 (I) Stopped engines and listened on sound gear. 1957 (I) Deadened to close track sharply just in case three was a radicel zig to the right. Come to 030° T and resumed speed. 2103 (I) On target predicted track. Since target could have passed ahead, decided to come to 345° T. 2330 (I) Should have made contact by this time unless target made radicel zig to the right or that last depth charging was a result of a GUDD3CN attack. Decided to return to vicinity of last depth charging. Chenged course to 165° T.

0013 (I) Radar back in commission. Got a look at targets when moon broke out of the clouds and saw ships which appeared to be two small destroyers. Docked that only chance to make attack was to go ahead of targets on base courses. Targets zigging between 115°T end 175°T it was apparent at this time that before we could get chase we might run into shore water off the northern BOMIN group. To int. rnit. tontly gained and lost contact but romainad as near base course as possible in order to gain in bearings. Ranges were obtained up to 1450yrcrs. No wnt unfortunately on the light side of the horizon and had to keep at least 10,000 yards out. Targets were to port. 0315 (I) Radar contact 127° relative range 5050 yrcrs. Could not see object although visibility in that sector was good. Decided it was small bot which would be difficult to so in this swells. It was on northerly course, speed about four knots. Soon lost contact. 0321 (I) Target group bearing 027°T, 10,000 yards. Targets now appeared to shift base course eastward to about 135°T. Believed at this time that they int. ntdc passing to eastward of islands. No over to eastward. 0340 (I) Went to battle stations. 0432 (I) Ranges and bearings indicate targets had slowed or stopped. Stopped, target bearing about 315°T. 0440 (I) Went ahead again in 4 - engine combination on 140°T. 0453 (I) Plot and TDC showed target course 160°T. Came to 190°T and at this time colled for the shock on neviational position. 0502 (I) Because of proximity of shots and since we could only get in if targets passed to eastward of BOMINs, as continuance of approach would have us against a dawn horizon, came to 120°T and later to 090°. 0506 (I) Land contact 155°T, 11 mils - we would have been a land mark had we continue. Destroyers passed to westward of shocks. 0542 (I) Submerged after taking morning stars. Proceeding towards return track. 1708 (I) Surfaced.

3225 (M) Although having not had any previous indications of approaching, took a big one over way such only causing a list of about 40 port and taking much water thru the conning tower hatch and the main and hull inductions. The popping sea caused the ship's head to swing about 140° in about a half a minutes. Major damage sustained was grounding out of the main control cubicle. Due to heavy seas it was not advisable to proceed on direct drive engines and therefore lay to until control cell grounds were cleared and on Feb. 13 2019 (M) proceed to rendezvous at MIDWAY.

(U) REMARKS
   - 1. A pin in the 6Y radar training shafting sheared during the tracking of two enemy destroyers. This was not apparent to those in the conning tower, who ultimately reported contact had been lost. A short time later the CDD and the C.O. noted that the radar head was not turning and asked for a check-up. The moral of this story is that the CDD must periodically check to see if the head is rotating.

2. Many grounds and short-circuits resulted from the serious popping experience by this vessel. One short-circuit not mentioned under "Damage and Defects" occurred in the conning tower behind the pyrotechnics locker. This could have resulted in a very serious situation. The circuit was pulled and the pyrotechnics shifted to a stowage space below. It is recommended that an insulated air-tight pyrotechnics stowage be provided for this vessel in the conning tower during the coming refit.

3. The C.O. believes the watch was sufficiently alert to have prevented popping under usual conditions. The system of closing valves is adequate to cope with anything except such a sudden, unpredictable casualty, at present the watch tends to over-correct, causing considerable discomfort by under-ventilating. Complaints have been heard from other boats in "bull sessions" concerning moisture starting into the main control cylinder via the hull ventilation system. The C.O. believes that, considering the importance of the equipment involved, the ventilation lines in the maneuvering room should be made pressure-tight and should have no outlets in that compartment.

Subject: U.S.S. SAURY Ninth War Patrol, comments on.

1. The U.S.S. SAURY's ninth war patrol was the fourth war patrol for Commander Dropp as commanding Officer. It covered a period of fifty-four days of which twenty-five days were spent in the area.

2. There was only one contact worthy of the title of "devil" in and attacking. This contact consisted of a task force commanded by the SAURY closed the track delivering that the GUDGON had made an attack. In this manner the SAURY lost contact with the carrier.

3. The health and morale of the crew on arrival from patrol was very good. Material was shipped during rough weather returning from patrol. She will be overhauled on the Test Coast.

4. The patrol was terminated by the provisions of the operation order.

5. The commanding officer, officers and crew are to be congratulated on the successful return from such a trying patrol in rough weather.

(21 December 1943 to 21 February 1944).

1. The ninth war patrol of the SAURY was conducted in the East China Sea.

2. The majority of the time in the area was spent fighting extremely low-level weather. Because of this bad weather the SAURY was unable to establish a periscope observation off the China Coast and thus close the coast in order to secure enemy shipping. No contacts were made worthy of torpedoes except two small destroyers or patrol vessels which could not be closed because of their high speed.

3. This patrol is not designated as successful for Combat Insignia Award.

tower hatch dog interlock. Spring on this interlock broke and
the pawl which normally fits under the hatch knife edge and
releases the dogs, managed to fit above the knife edge pre-
venting closing of the hatch. Caught things in time taking
only a minor amount of water. A new locking device which can-
not get between the hatch and knife edge should be designed.

6 August 1944
0429(H) Submerged.
0536(H) Sighted masts of AK bearing 153 1/2°T distance about 1500 yards. Commenced approach using standard speed and normal approach courses. Observations were made difficult by glassy calm sea requiring slow speed for looks. No escorts were visible although sound at 7500 yards detected light fast screws with the targets, and target base course checked about 355°T speed 12 - 13 knots.
0652(H) With true bearing 044°T and range 9400 yards, abandoned approach. At 0705(H) changed course to 090° to get farther away from land. Surface visibility was unlimited, peaks on Luzon could be seen at ranges in excess of 60 miles, scattered clouds. Did not see much chance with visibility, proximity to land, and speed of the target to make a successful end-around but at 0830(H) surfaced at four engine speed for an end-around to eastward of target.

(C) WEATHER

Throughout the entire patrol light breezes to flat calms prevailed. Visibility was generally unlimited with a few rain squalls. August 12 - 13 had the only rough weather - force 4 SW winds, number 3 seas and rain with subsequent reduced visibility. The moon light nights in this area were really light. Visibility ranges to land of 40 - 60 miles were the rule and not the exception.

(D) TIDAL INFORMATION

Tides found near San Bernardino Strait agreed with those on charts of the area. We stayed away from areas of indicated strong currents, found none in excess of 1.5 knots. The only irregularity found was a continual set toward 010°T for two days during a 12 knot wind from the south.

(E) NAVIGATIONAL AIDS

Ungay Point light house, eastern end of Rapu Rapu Island, a white cylindrical tower was always very prominent in the daytime. The area around the light was cleared away. The light was believed lighted some nights, though there were always brush fires nearby.

The interlock spring, piece #6, b.c.e. We had been warned that it might so a spare was on board. However, with the spring broken it is possible for the interlock lever, piece #1, to fall into position between the hatch knife edge and gasket. SAURY could have dived with the conning tower securely blocked open.

4. The section of pipe which necessitated the second and late start on patrol, the salt water cooling line to the port motors, had been tested during Navy Yard overhaul but had not been replaced. It was a copper line and badly corroded. It was inaccessible for complete repair underway, needed complete renewal. A new copper-nickel section was installed by U.S.S. HOLLAND.

5. Three (3) cracked cylinder liners were experienced on the direct drive engines, units #3 and #6, respectively on #3 engine and unit #16 on #4 engine.

(L) RADIO

All ComSubPac serials were received. From 1900 local time to about 0300, reception was usually best on 0900 ko. From 0300 until daylight, better results were obtained on 6380 ko. Receipt-test was very good on 4155 ko, the China ComNav Group station. The no difficulty with the exception of those of 130443 and 091440 which could not be broken. Some error was apparently made in encoding these two.

When the inter-area frequency was changed to 2880 ko, it was no longer possible to guard that frequency, the Haiku frequency, and 4155 ko simultaneously, due to lack of receiving facilities. These frequencies are within the range of the RBO but that receiver is not adapted to the reception of CW.

(M) RADAR

Little use was made of the SD in the area because practically all daylight hours were spent submerged. When it was used, on the way to and from the area, results were as good as is expected from the SD. Because of occasional instances when planes have been picked up by the lookouts before the SD showed them, we have learned not to rely too heavily on it. However, planes were picked up at 18 miles while enroute to the area and in the vicinity of friendly bases the response of the BN on the SD was very satisfactory.

The performance of the 5J was good. Excellent ranges of 85000 yards and more were made on the land in the vicinity of which we patrolled. A U.S. submarine was tracked out to 19700 yards. Occasional difficulty was experienced with "ghost" targets, usually in the early morning hours. It is believed that these were due to some atmospheric condition. The size of the "ghost" pips usually

(U) REMARKS

The present arrangement of the icebox (altered when magazines were changed for 4" and 5" stowage) is not satisfactory. Either a rearrangement of coils, shelves, and ventilation or a compromise of each is required to utilize the present refrigerating space. The excessive amount of meat spoiled and thrown overboard on 12 August shows the necessity of an improvement. At no time during the patrol was the ice box out of commission so that spoilage could be traced to that source.

A general improvement is noted in time of quick submergence. Previously, average time under all conditions was around 60 sec. This now is reduced to 50 sec. The only feature apparent which seems to have brought about this condition is the use of #3A and 3B MET for reserve fuel.

Subject: U.S.S. SAURY - Tenth War Patrol - Comment on.

1. The tenth war patrol of the U.S.S. SAURY was conducted off the East Coast of Luzon. The vessel was on station from July 18 to August 15 and the entire time was spent in guarding the San Bernardino Strait except for one four day shift to the Northward.

2. During this latter period, an enemy AK was encountered on a favorable base track but her zig plan enabled her to elude the submarine's approach. This was followed by an attempted end-around which was broken off when SAURY dived on a fast closing radar contact at 14 miles. Except for one periscope sighting and a few small fishing boats, no other shipping could be located off the Strait.

3. SAURY returned from patrol in generally good material condition. Refit will be conducted by SFERRY and Division 102. The vessel will be docked and an attempt made to reduce the squelching of the tail shafts by packing them with sand. It is unfortunate that this job was not completed during the recent navy yard overhaul. The ice box will be modified.

4. Attention is invited to the dangerous casualty caused by failure of the new type conning tower hatch interlock. The tender is requested to submit a detailed report on the design features of this device.

5. Commander Submarine Division 102 welcomes the personnel of the SAURY to Majuro after a trying patrol.

1. The tenth war patrol of the SAURY was conducted off San Bernardino Strait.
2. For 28 days in area the SAURY was unfortunate enough to have only one ship contact. The negative information value derived from such a patrol in this area where man-of-war contacts are always probable is considerable. It is hoped, however, that the SAURY will have an opportunity for action with the enemy during her next patrol.
3. This patrol is not designated as "Successful" for Combat Insignia Award.

20 SEPTEMBER 1944

On 23 August 1944, returned to Majuro from TENNHW war patrol. Assigned to Submarine Division 102 and U.S.S. SPERRY for refit. On 26 August, Comdr. A. H. DROPF was relieved as Commanding Officer by Lieutenant-Cmdr. J. C. NICHOLS, U.S.N. On 30 August, Lieutenant-Cmdr. J. C. NICHOLS was detached in accordance with ComSubPac orders, serial 0-2273, dated 30 August 1944. On 2 September, Lieutenant-Cmdr. R. A. WAUGH, U.S.N. assumed command in accordance with orders issued by Commander Advanced Base 1324.

In addition, Lieutenant (jg) T. F. DUFFY was detached to new construction and Lieutenant R. O'NEILL, Jr., U.S.N. and Lieutenant W. B. GRIFFITH, U.S.N.R. reported on board for duty.

Refit completed 6 September. Ship docked at afts packed with sand. Three day post-repair period, and seven days daylight training. Fired six Mk. 16 exercise torpedoes.

During loading period, discovered outboard leak in 3-B fuel ballast tank resulting from cracked framing installed in accomplishing alteration to # 2 main engine circulating water sea suction. Assigned to U.S.S. BUSHNELL for accomplishing repairs and final loading. Readiness for sea date delayed one day to 20 September 1944.

(B) NARRATIVE:

20 September 1944

0800 L Underway for patrol in accordance with ComSubPac operation order 320-44. Task unit designation 17.1.3.

O850 T. Passed channel entrance, enroute north safety lane in company with U.S.S. CROUFER (DELL). Made trim dive outside entrance.

1245 L Proceeding independently at 2 engine speed.

21 September 1944

Enroute to area on surface conducting daily drills and training dives.

1714 L Sighted tops of three unidentified merchantmen and one, maybe two, escorts from periscope sheers. We were near the northern end of the safety lane and had received no notification of possible sighting of friendly ships, so sent contact report to verify identity of ships. Continued ahead until notified that convoy was friendly.

COD said angle between lights increased considerably like plane was coming out of a turn, and position angle increased rapidly; it's looked like wing-tip lights. Three to four minutes prior to sighting, APR-1 had radar interference on 151 mo. SD radar was not in use. We were about 170 miles west of Wake.

Moon well up, about 3/4 full, so started making end around to northward on 3 engines, charging on one, planning to fire with target silhouetted.

About two hours after sunset, target changed zig plan, zigging between 230 and 290. This base course showed target enroute from Bonins to Okina Cagari Jima. This

2159 I Submerged to radar depth. At 7,000 yards could see target in periscope, and at 5,000 yards went to periscope depth. At

2226 I range 3,500 yards, started in for bow shot. Was coming left for 90 port track when target zigged toward. I called the angle on the bow 10 S, made ready stern tubes, and headed out for stern shot at standard speed. This was a mistake. TDC operator said angle on bow should be 10 port if target was following zig plan. Angle on bow was hard to determine, but after checking I saw it was port, I was heading for his track, about 30 yards off it, so decided to try to cross ahead and shot with a large starboard track. Went to 90 feet, and all was checking well when sound bearings indicated another zig away. Came up to periscope depth, coming right at the same time for possible large port track. Tried several times to get ping ranges, but unable to do so. At

2239 I at periscope depth. Target showing large angle on bow, about 160 port. Torpedo run at this time was 3,000 yards and gyro angles nearly 160. This was my first target and I didn't want to pass him up, so gave the order to fire thru torpedoes, with no spread, assuming natural dispersion of torpedoes would take care of a spread at the long range. At

2240 I fired 3 torpedoes, depth set six feet. No hits.

2246-50 One explosion; probably torpedo at end of run.

I had expended a lot of fuel and three torpedoes on this fellow. I was already behind schedule getting to my area and I didn't figure the target was worth the fuel and torpedoes for another end around. Made reload aft and at

Patrolling near eastern edge of area as directed. From the center of the patrol spot selected, I figured I could intercept any forces' moving south from Bungo Studio, and possibly from Sasebo.

0528 I Submerged. I intended to surface about 1100, to avoid the 1000 search plane previously encountered in this vicinity.

1030 I Sound picked up a loud clanking noise, on a broad bearing on the starboard beam. It was thought at first that the noise originated on board. After securing everything on the ship's' except breathing, and making several course changes, the noise was finally determined to originate elsewhere than on the ship. We tracked this for about 2 1/2 hours; nothing in sight at 50 feet. I never did decide what the cause of the noise was. It wasn't fish. Thought it must be a submarine.

1457 I Surface. Started surface patrol at 2 engine speed on east-west courses, two hour legs on each course.

1935 I 3J reported rain squall at 35,000 yards, bearing 315(T). Visibility was fair, but it was all clear on that bearing. During a 2 hour period, this 'contact' closed in to 4,000 yards where it faded out; it appeared to be a rain squall all the way in on the radar screen, but the horizon was clear. Apparently this was a double echo from land.

2335 I Flashes were definitely gunfire. Continued closing at 17 knots.

2346 I Could make out muzzle flash as guns were fired. This looked like heavy caliber gunfire, quite definitely salvo fire. There were smaller sporadic flashes in the vicinity such as would come from anti-aircraft guns. Salvo interval on the big flashes was 40 seconds. I couldn't feature the Japs holding a test firing on the eve of battle, yet I had no word of friendly forces in the area. Although the firing was in one general locality, I didn't figure the Japs were shooting at each other, and therefore assumed that some units of our surface forces were in the vicinity. Not being particularly desirous of getting in the midst of a night melee where I couldn't tell friend from foe, I continued to close the area but headed in a northeasterly direction.

If this force was the one previously reported to us, and this seems logical, then their track was north of the track reported, and the force was headed for Nakagusuku Wan, where they should have arrived about 0300.

C316 I Range 2,400, angle on bow about 100 port, about ready to start firing, when target commenced changing course. I couldn't tell if angle on bow was zero or 180, but rapidly decreasing range soon settled that. We had been detected although I don't know how.

C317 I Left full rudder, all ahead emergency. Range was 2,000 yds, bearing about 010, angle on bow zero. Hade ready stern tubes and prayd for hydraulic outer doors. Hand operation was just as quick however. As we pulled off track, angle on bow increased rapidly. Gave coming tower quick set-up of angle on bow of 50 starboard.

Told maneuvering to pour on the coal, and brought lookouts down to bridge level. I expected bullets to start through the air at any moment, and thanked the Lord that none did. Range gradually opened, but it was an anxious 5 minutes.

Well, at the range we fired, we should have hit that guy with spuds. Investigation revealed the following:

Although bridge called out angle on bow of 50 starboard (twice), coming tower undertook the order as 50 starboard. This is just an unfortunate control

error which occurred in the confusion of a quick change in set-up. In addition, target undoubtedly speeded up after first detecting us, but there was insufficient time to note this on TDC as we went from all ahead emergency to all stop prior to firing; and even though TDC operator was anticipating lag of pit log by land input, the situation changed so rapidly that TDC solution was difficult.

After recovering from this ramming episode, and deciding future course of action, it was apparent target was heading now for Torii Shima, about 45 miles distant. Dawn was approaching and a daylight end around didn't seem feasible. I knew the enemy would be thoroughly alerted after the first attack, but I didn't expect to be detected from our position on the second one.

It would help to have on the sextant, one nearly clear shade glass for dimming bright stars. When the horizon is poor it is obscured by the glare or loom of a bright star. At present all shades are too dark.

TARGET DATA - DAMAGE INFLICTED

Description: Target was a medium tanker, believed diesel driven, similar to TAKAO class described in ONI Weekly of 2 August 1944.

FIRE CONTROL AND TORPEDO DATA

Type of Attack: Night surface attack, radar ranges, TTP bearings.
When coming in on a 110 port track, and about
ready to fire bow tubes, target detected sub-
marine and turned toward to ram. Filled off
track at emergency speed, stopped, gave quick
set-up for stern tubes and fired. Unfortunately
TDO misunderstood reported angle on bow and
first set in 30° starboard instead of 90°
starboard. Immediately after firing, target
again headed toward to ram.

U.S.S. SAURY (SS169) - Report of ELEVENTH War Patrol.

(I) RADIO

Radio was generally satisfactory. All serials were received. All transmissions were quickly completed.

There was a great deal of radio interference encountered on the schedule frequencies but signals came in well and could be copied. The "real" frequencies are satisfactory. The frequency shifts are compromised however as boats could always be heard shifting transmitter frequencies on schedule, tuning up with antennas out in.

On night of 27 October, arefrequency was most effectively jammed by the USES during a coordinated attack on tanker by SALMON, SILVERBIRDS, an enemy others.

The SALMON'S VHF, quickly transferred at Saipan was not needed or used. In fact it went out during one of our fastest divas, the antenna pressure pipe cracked and leaked badly. The shear valve stopped the hull leak.

(M) RADAR

All radar equipment gave very good results. Only one failure caused a unit to be out of commission for more than a few minutes. The 3W was out during one night, rezult-bly during ship contact #4. The trouble was a multitude of little irregularities, the main ones being failure of the modulation network, a condenser in the bins generator C22E, and a rectifier tube in the range unit. U.S. Submarine was tracked to 16,500 yds by 3R radar. Communication by 3R proved very efficient, was used extensively.

Coordinated use of AR, 3D, 3F, and lookouts was interesting, sometimes nerve wrecking. An example of this occurred on 27 September 1944. Signal at 80 no was picked up by AR. 3D was keyed to chock and was found jammed with interference, contact not possibly identifiable. A plane was sighted, bearing 250, barely visible through binoculars, this five minutes after the first AR contact.

A great deal of confidence by the crew an interest by the watch-standers during what otherwise would have become dull watches, resulted from an attempt to organize and to recognize the contributions and limitations of each piece of equipment.

A complete report, summary and itemized list of results follows:

CONCLUSIONS AND SUMMARY

1. Care must be exercised in the use of the APR detector because of numerous local interferences such as the radio transmitter, SD radar, SJ radar (even in standby condition), EOM machine, bed connections, and Heterodyning circuit of unit itself, blinker tube or other buzzer. These interferences occur at definite frequencies, however, and can be isolated in time. Following are example of frequencies at which local interferences occurred:

(a) 130 mc - 60 cycle rushing noise - SD radar, standby condition.

(b) 268 - 272 mc - 1500 cycle note - SJ radar, standby condition.

(c) 65 mc - Radio transmitter sending CW on 4235 kc.

(d) 244 mc - Blinker tube buzzer.

(e) 151.5 mc - Radio transmitter sending CW on 8470 kc.

2. As much as 12 minutes warning prior to arrival of enemy radar equipped planes may be given by an alert APR operator. Use of SD radar in conjunction with APR shows planes often do not come directly in, but come to within approximately 10 miles and then complete approach after perhaps a minute or more of delay. During this interval the warning signal may go away entirely.

3. Plane contacts, verified either by sight or by SD or SJ radar were made on:

80 mc.
96 mc.
150.5 mc.
176 mc (believed friendly)
529 mc. (believed friendly).

4. Landbased radars were consistently picked up on:

80-81 mc., 99 mc., and 146 - 156 mc.

REMARKS:
Delivered friendly ship, same frequency band and PRF as our SA or SO. Held constant for about an hour. Many friendly ships in area.

This signal heard frequently sometimes as static noise, while errupture from Mejuro to Nansei Shoto. At specific time was forced down by flame glowing running lights. Also frequently heard running lights. Also frequently heard in area around Nansei Shoto, but heard as true signal and not just static noise. At night could be received from a great range.

Signal picked up about 15 minutes before plane was sighted bearing 260° and out of visible range of naked eye. Upon receiving signal SD was keyed to check and screen was completely jammed with interference. Plane pip not distinguishable.

Signal picked up about 15 minutes before plane was sighted, "Looked like a bomber". This is in frequency range of our ASW which has PRF of 325-435. Believed to be friendly plane.

Operators had been puzzled by this signal present with radio transmitter off, SD variable down. Found to disappear when Power Switch of SD was turned off. Probably due to IP beat oscilltator. IP frequency of SD is 15 me and RF is about 115 me.

USS SAURY Report of
Eleventh War Patrol.

From: The Commander Submarine Division FORTY-FOUR.
To: The Commander-in-Chief, United States Fleet.
Via: (1) The Commander Submarine Squadron FOUR.
(2) The Commander Submarine Force, Pacific Fleet.
(3) The Commander-in-Chief, U.S. Pacific Fleet.

Subject: U.S.S. SAURY (SS189) Report of Eleventh War Patrol.

1. The eleventh war patrol of the SAURY, the first for the commanding officer as such, conducted in the NANSEL SHO TO Area, was of sixty-eight days duration, thirty-four of which were spent in the assigned area. During the latter part of the patrol and after five days voyage repairs at SAURY the ship joined the SILVERSTEDES, TRIGGER, TAMOR, STERLETT and BURNFISH Task Group under the command of Commander T.B. KLAKIN for operations southeast of HONSHU.

2. During the patrol the SAURY made three contacts which were attacked by torpedoes. First a small AK on 29 September, Second a trawler patrol boat on 15 November and third a medium tanker on 18 November. Torpedo at-acks were unsuccessful except for one hit on the tanker attacked on 18 November. On 15 October the SAURY sighted gunfire and the decision not to develop this contact was unfortunate for this was later determined to be an enemy task force. On 18 October the SAURY rescued Lieutenant (jg) D.R. KEMN, U.S.N.R., who had been in the water for two and a half days. This was an excellent job, intelligently carried to a successful conclusion.

3. FIRST TORPEDO ATTACK - This was a night radar and periscope attack after an end around on a small unsupported freighter. Three Mark 18-1 torpedoes fired on 1500 trawl with 3000 yard torpedo run missed. The commanding officer mistaking the angle on the bow for starboard when it was actually was port probably allowed this target to get away. Gyros were small and depth set was six feet.

SECOND TORPEDO ATTACK - This was a night surface attack on a stopped armed trawler. Four Mark 18-1 torpedoes were fired on a 900 trawl, all missed, two apparently underran the target. Depth was set at zero and gyros were near zero.

THIRD and FOURTH TORPEDO ATTACK - This was a night surface attack on a medium tanker. Four Mark 18-1 torpedoes set at six feet were fired obtaining one hit. Target slowed then speeded up after this hit and another attack was made. Four Mark 18-1 torpedoes were fired from the stern tubes depth set at two feet torpedo run 900 yards, gyros about 26°. All missed due to a failure of the approach party to understand the commanding officer's estimate of the angle on the bow.

4. The summary of enemy radar activity is well prepared and should be of value to other submarines.

— page 135 —
5. The 3AURY returned from patrol in a good material condition and in an excellent state of cleanliness. Refit will be accomplished by the Submarine Base in the normal time and defects noted in the patrol report will be corrected.

6. The officers and crew are congratulated on the damage inflicted on the enemy and for the rescue of an aviator.

U.S.S. SAURY - ELEVENTH 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. SAURY (SSI89) - Report of Eleventh War Patrol, 29 November.

1. The eleventh war patrol of the SAURY was conducted in two phases. In the first phase, the SAURY conducted patrol in the areas around Nansai Shoto. In the second phase, the SAURY was one of seven submarines that carried out an anti-patrol vessel sweep north of the Bonin Islands.

2. During the first phase, the SAURY was in an area that was depleting of enemy traffic because of the air strikes being conducted in and around that area by the Third Fleet carrier forces. The rescue of a naval aviator, after being adrift over three days, far at sea was particularly marititious.

3. The report of radar activity submitted appears to be a very thorough analysis that should be of future benefit to both surface and air forces.

4. During phase two of this patrol, the SAURY made two aggressive attacks on an enemy tanker, one of which damaged her.

5. Award of the submarine Combat Insignia is authorized for this patrol.

6. The Commander Submarine Force, Pacific Fleet, congratulates the commanding officer, officer, and crew for having inflicted the following damage upon the enemy:

In this abortive attack the three submarines expended over three hundred rounds of deck gun ammunition but did not destroy the patrol craft. The peak commander assumes the responsibility for this failure by having allocated to "shoot it out" at long and inter-mediate ranges instead of closing for the kill. I did not see how we could close the range to this accurate shooting vessel without having one of the submarines holed and I did not detect the prize to be worth that price.

The group commander was Commander T. S. Makrin, U.S. Navy. The mission of the group was to make an anti-patrol vessel sweep in the areas west and north of the Volcano and Sonin Islands.

In spite of rough weather, which was prevalent most of the time in area, the group succeeded in inflicting damage upon the enemy with both torpedoes and guns. All submarines conducted aggressive attacks when contacts were made, and the military advantage was retained in all cases where gun attacks were made. The performances of the Patrol, Patrol, and Patrol were particularly outstanding although all seven submarines contributed to the success of this mission.

The fact brought out by the group commander that such an anti-patrol vessel does not by the group commander that such but to the contrary brings no relief of the enemy. Nevertheless the overall reduction is valuable.

The Commander Submarine Force, Pacific Fleet, congratulates the Commander of Task Group SEVENTEEN POINT TENTY-FOUR for the successful accomplishment of his mission and for the efficient manner in which it was planned. He joins the group Commander in congratulating the commanding officers of all seven submarines who participated in this sweep for their a-cessive conduct throughout the entire patrol. Task Group SEVENTEEN POINT TENTY-FOUR is credited with having inflicted the following damage upon the enemy:
