1939 (I)
Surfaceed. Commenced closing Kantori Saki light at slow speed, intending to dive before dawn close to shore. Land picked up by radar at minimum range of 34,000. Had experienced strong set to south-east during daylight submergence. Bright moonlight; changing course to reduce silhouette to a minimum, intending to close land at two engine speed after moon-set at 0157 (I) on the 13th.

2351 (I)
Sighted unlisted 3sec. navigational white light flashing every 3 sec. in general direction of Shimo Misaki. Steady white light to northward possibly Kantori Saki with normal characteristics.

August 13, 1943
0000 (I)
Conducting slow patrol on course 240° T (into the moon) 24 miles bearing 094° T from Shimo Misaki light.

0125 (I)
Changed course to 3100 T.

0155 (I)
Changed course to 0900 T. SJ radar contact bearing 2650 T distant 18,700 yards.

0210 (I)
Changed course to 3100 T.

0228 (I)
SJ radar has contacts on two ships, one large and one small. Small ship apparently ahead of and conducting patrol for large ship. Target base course 0350 T. Commenced closing track and obtaining position ahead. Plot and TDC speed of targets 8.5 knots. Continued tracking.

0332 (I)
In position ahead of targets; range 7650 yards; own and target course 0350 T; angle on the bow zero. Plot shows large target to be following zig-zag plan of 4 to 20 minutes legs, courses varying from 015 to 0550 T.

Visibility to west very poor. Visibility to east gradually improving. Dawn expected at 0400 (I), sunrise at 0511 (I).

Decided not to attack on surface from westward because of close proximity to the shore. Navigational position not definitely determined since 0430 (I) of preceding day.

Decided not to attack on surface from eastward because of visibility advantage for enemy and short time remaining before dawn.

— page 12 —
0411 (I) Target course now 015° T. Decided to open range on port bow of target, dive to 40 feet, and gain position for periscope approach in early morning light.

: 0413 (I) S,bmerged to 40 feet on course 015° T. Lost radar contact after dive.

: 0436 (I) Regained radar contact on bearing 200° T, range 3500 yards.

: 0438 (I) Small vessel in sight by #1 periscope. Went to 62 feet.

: 0441 (I) Changed course to 080° T.

: 0450 (I) Small vessel made large zig to westward.

: Commenced approach, hoping for large zig toward. Running at 80 feet when closing range. Sea flat calm. Visibility poor. Sound conditions very poor.

: 0509 (I) Target zigged toward.

: 0511 (I) Sighted sizeable freighter about 4000 yards astern of small one.

: Continued approach. Target now definitely determined to be small old steamer of about 2-3000 tons.

: 0518 (I) Decided to let small freighter go by (range 1200 yards about) and attack the larger one. Came to southeastly course. Large steamer identified as merchantman of about 7000 tons; the TATUKIMI MARU page 71 of ONI 03-1.

: 0524 (I) Sighted anti-submarine craft of unusual features about 1500 yards on our starboard quarter. Smooth seas and the fact that we were engaged in an approach reported detailed observation of this ship. She was probably of about 100 tons, a high sided, blunt-ended craft, without a real bridge structure. On her bow was a deck most of torpedo tubes or depth charge throwers, and on her high stern prominent built up racks. Subsequently the sound of her propellors was described by the sound man as very high in pitch and "feathery". That looked like a large windsail was spread in her waist.

Anti submarine vessel was making slow speed on a northerly course.

0529 (I) Position of anti-submarine vessel discouraged turn to left for better track angle. Decided to fire 4 torpedoes with left gyro angle. Torpedo run 1200 yards, 12° total spread, continuous bearings to TDC during firing.

: 0535 (I) Fired four torpedoes, 7 second firing interval. First torpedo (45 second run) observed to hit freighter amidships directly under stack. Splash of water soon by Commanding Officer. Target lurched to port. Observation of anti-submarine vessel prevented further sighting of torpedo hits. Two thuds and two low order explosions heard by personnel of forward torpedo room approximately one minute after firing. All torpedoes heard running and taking left angles by sound. Target's screws not heard at any time after firing and during following depth charging although sound had good contact before firing. Believed that two torpedoes hit this target but cannot account for lack of normal detonations. All torpedoes were fitted with torpex heads.

During firing the anti-submarine vessel was about 800 yards astern on a northerly course. After torpedo hit, personnel of target and anti-submarine vessel were observed pointing in direction of periscope.

Previous to this time it had been noted that the target had two tow wires out astern. Possibly trialing depth charges. No tow sighted.

Target manned and trained out gun aft. Escort turning toward us.

0536-30 (I) Ordered depth "90 feet".

0538 (I) First depth charge; went to 230 feet. Definite negative gradient. This attack was followed by two more, during which a total of only six charges were dropped, none of which was alarmingly close. Evasive action taken: turn to right at standard speed while going deep followed by a wide circle to left at 40 rpm.

0608 (I) Steadied on course 150° T.

0634 (I) Lost sound contact with fast lift screws on bearing 240° relative.

Swinging slowly to left.

0720 (I) Had short sound contact fading out astern.

0721 (I) Steadied on course 0900 T, clearing vicinity of attack.
: 1040 (I) Nothing in sight by periscope. Long, slow swells with flat calm surface.
: 1050 (I) Made reload at 150 feet. Secured from silent running condition.
: 1325 (I) Heard depth charge explosion at considerable distance. Sonic search vessels had re-established contact and proceeded to carry out a series of attacks. Dropping a torch, we could see depth charges, none of which was dangerous. Close or damaging to the boat. Search procedure was as usual and extensive tactics consisted of changing course at mid-time of close period when search vessels were lying to and listening. General evasion course 135° T. Ideal sound conditions for enemy sonic search.
: 1852 (I) Last depth charge. Lost sound contact shortly thereafter and believe that search vessels were left behind as PADDLE cleared the vicinity on course 200° T.
: 2205 (I) Surfaced. Flat calm sea. Bright moonlight. Departed for south-western corner of area at 4° 30' N, 120° W speed.
: 2335 (I) Slowed to one engine.

August 14, 1943

: 0000 (I) Continuing to south-western corner of area at 4° 30' N, 120° W speed.
: 0433 (I) Submerged and changed to course 000° T, closing Funtori Saki light.
No contacts during the day.
: 1745 (I) Changed to course 090° T.
: 1932 (I) Surfaced. Generally overcast with fair visibility.

August 16, 1943

: 0330 (I) Moon commenced undergoing a partial eclipse.
: 0415 (I) Submerged on course 315° T closing Miki Saki Light.
: 0643 (I) Periscope contact with patrolling aircraft, observation type, that banked forward during sighting. Went to 90 feet, but plane took no further action.
: 0700 (I) Returned to periscope depth. Sighted smoke from the first of several small coast-wisestreamers picked up close to shore within the 100 fathom curve rounding Miki Saki light.
: 0730 (I) Second periscope contact with patrolling aircraft, observation type. No action by plane.

Visibility during the day was excellent. Several small coast-wisestreamers, trawlers, sailing craft, and fishing boats were sighted close in while we were patrolling 2 miles off Miki Saki light on 100 fathom curve, but nothing appeared worth shooting at.

: 1400 (I) Commenced withdrawing from coast to westward in hope of picking up larger ship about 10 miles off shore and in preparation for surfacing in full moon.
: 1943 (I) Surfaced. Commenced battery charge and slow patrol to westward. Bright moonlit night. Visibility excellent.

0032 (I) Lookout sighted small ship bearing (053° relative) 090° I, angle on the bow zero, range about 9,000 yards.

: 0032 (I) Changed course left to reduce silhouette, put target astern, and commenced tracking. SJ radar has contact on land at 18 miles but cannot pick up target.

: 0040 (I) Steadied on course 230° T. Target closing at high speed. Has general appearance of a patrol vessel. Increased to two engine speed.

: 0057 (I) Target closing to range of 5,000 yards. His speed about 18 knots. Changed course to right and target changed to right.

: 0105 (I) Commenced slow turn to left. Target changed to left. Increased to four engine speed and steadied on course 220° T. Target continued to close before our increase to 20.5 knots. She has narrow beam and general silhouette of a torpedo boat. SJ radar cannot establish contact although range is less than 6,000 yards and the vessel is promising an excellent target. Believe this patrol vessel to be of wood and capable of at least 18 knots. True bearing slowly drawing to north as P.DDLE gains at 20.5 knots.

: 0157 (I) Changed to course 180° T. Visibility remains excellent. Enemy very slowly dropping astern.

: 0245 (I) Enemy disappearing from view on true bearing 035° T distant 14,000 yards.

Believe that this anti-submarine vessel saw P.DDLE before or at same time as we first saw her, and attempted to chase us in toward the shore. The inability to make contact by SJ radar, her general appearance (definitely not that of a merchant ship), her aggressive action and highly suspicious conduct, her relatively small size, and high speed convinced us that here was no craft to attack in bright moonlight and a flat calm sea.

Continued to southward and dove at 0356 (I) in position 50 miles bearing 135° T from Shiono Misaki light. Commenced poriscope patrol on course 315° T.

TARGET DATA - DAMAGE INFLICTED

Description: Ship attacked was a 7065 ton T.KUKUMI M.RU type (page 71 of ORI 208-J). She was contacted by radar at 18,700 yards at 01515 (I) under conditions of good visibility. Visibility would have prevented a surface attack. The T.KUKUMI M.RU was accompanied by an unknown freighter of 2-3000 tons that acted as a screen ahead of and on either bow. At time of attack she was joining up with an escort vessel to form an escorted convoy.

Ship Damaged: T.KUKUMI M.RU (7065 tons)

Damage determined by: Target was hit by two torpedo head torpedoes. The first torpedo was seen to hit by the Commanding Officer and forward torpedo room personnel heard two thuds and two low order detonations. The target lurched to port after being hit and then righted herself. No further observation of damage was possible due to depth charging by the escort. No reason is known for lack of normal detonations by torpedoes on hitting. Sound lost contact with target propellers after torpedo firing.

Target draft: 20 ft. est. Course: 038° T Speed: 10 kts. Range 1060 yds.

OWN SHIP DATA

Speed: 3.2 knts. Course: 168-165°T Depth: 63 ft. Angle: 20° down

FIRE CONTROL AND TORPEDO DATA

Target was tracked by radar for course and speed. Visibility and proximity to shore prevented surface approach. Doves at dawn ahead of target and used radar at 40 feet. Attack conducted in early morning, lit by periscope. Continuous periscope bearings to TDC during firing.

TARGET DATA - DAMAGE INFLICTED

Description:
Sighted by periscope submerged three ship convoy with one escort patrolling ahead. Visibility excellent. Good periscope weather. Convoy was in column and simultaneously making constant helm changes of course and proceeding to the west very close to the shore-line. Convoy consisted of (2) 4000 non-descript freighter ahead and (1) 6000 ton freighter astern. Similar to the BOSTON MARU (Page 211 of OEI 208-J). The convoy had the air patrol usual in this locality.

Ship Sunk:
6000 ton freighter similar to the BOSTON MARU.

Damage determined by:
First torpedo seen to hit under stack. Third torpedo seen to hit in stern. Ship listed heavily to port and went down by stern. Side and topside structure seen blown open. Fire broke out amidahips and aft. Last seen very low in water with deck awash aft. No further damage observed due to close bombing attack.

ATTACK 2 (a)

Target draft: 20 ft. ast. Course: 285° T Speed: 8 kts. Range: 500 yds

OWN SHIP DATA

Speed: 4.0 kts. Course: 020° T Depth: 63 feet. Angle: 2° down

FIRE CONTROL AND TORPEDO DATA

Type attack:
It was entirely a periscope attack with fair periscope weather. Plane patrol apparently sighted P.DDLE and dropped a warning bomb shortly before own firing. Convoy constant helm changes of course made approach difficult. The approach was made on the second 4000 ton freighter to a position with 1700 yard torpedo run and 105 port track when this target turned away. Attack was then shifted to the larger ship astern.

Continuous bearings from periscope given to TDC during firing.

(J) 2. NTI SUBLIME MESURES AND EVASION TACTICS

The Japanese wore observed to carry out a regular inshore air patrol using small observation planes (land and sea) and an off-shore sector patrol using four-engine flying boats and two-engine bombers. These patrols are not too efficient but over smooth waters they can spot a periscope with proficiency. Air support continues to arrive promptly at the scene of attack. The patrol altitude appeared average about 1200 feet.

Surface patrol tactics apparently remain the same. There was no evidence of any regular patrol or picket line night or day. At night numerous lighted vessels were observed serving mainly as submarines, but they can thwart an attack.

Ship's and convoys steaming close inshore have ineffective protective escorts, but after an attack or when a submarines presence is definitely established by other means, the surface patrol vessels and escorts become most efficient and tenacious. Their use of echo-ranging appeared to be the exception to the rule after that time. We were unable to detect any propeller noises during many of the depth charge attacks. Although we used Bathytheromograph indications of density layers to best advantage we were trailed and contact was easily maintained by the enemy, presumably using sonic devices. The Japs are very efficient with their sound listeners but not so with echo-ranging.

The S vessels encountered were mostly nondescript types but one occasion we sighted a small fleet of seven new-looking patrol vessels in formation. These had the appearance of our sub-chasers. It may have been one of this class that used 18 knots chasing us the night of 17 -u-ust. The "SJ" radar failed to get any "pips" on this vessel even when the estimated visual range was as low as 5000 yards. Apparently there is very little metal used in their construction.

Observations and experiences indicate a well established and organized S base located in O Shima Ko.

The target hit on the 13th of August had a light tow line out from each counter from which may have been trailing depth charges or some other S device. Nothing was sighted at the end of the tow lines.

Evasion tactics consisted of running deep and silently. Slow turns, usually to put the search vessels astern, were made during the time when lack of propellor noises indicated that search vessels had stopped to listen and plot. It is believed that the Japanese drop single or groups of two and three depth charges occasionally with the hope of making the submarine speed up or otherwise make more noise.

All large ships except that hit on August 13th were using constant helm changes of course. Ship hit on 13th was joining up with escort of time of attack.

   - OUT OF COMMISSION: 2 hours

2. Stern Plane Tilting Control Switch
   - Stern plane operating and tilting control switch in control room stripped Allen set screw holding handle to shaft. Short circuited switch, planes stopped on 15 degrees dive. Unable to shift to hand until circuit broken at selector switch in after torpedo room, since solenoid was energized and clutch could not be thrown. Repaired by filing shaft flat and putting in new Allen set screw.
   - OUT OF COMMISSION: No power operation for ten minutes.

3. BOW AND STERN PLANES
   - Contactor bar (Cutler Hammer #175) of bow planes broke seven times during patrol. Power was lost on the planes, although casualty had not occurred before on the bow planes, although it had occurred three times in the stern planes panel, and occurred twice again during patrol. The break is always at the same place. Attempts were made to obtain stronger bars from the tender prior to patrol, but none were available, and their manufacture was beyond capacity of tender force. Additional spares were obtained and by making daily inspections of panels an attempt was made to find faults before they could develop to the breaking point. This method was but moderately successful and loss of plane control may occur at any time and did occur during one attack.
   - OUT OF COMMISSION: No power operation for at least ten minutes each time.

4. HOISTING CONTACTOR ON NUMBER TWO PERISCOPE
   - The hoisting contactor on #2 periscope short circuited throwing a large arc. Surface examination revealed no cause, but showed that arcing was from hinged portion of arc chute around contactor #225. Disassembled contactor and removed chute. Insulation readings were low, and it was found that the two insulating washers on the coil had carbonized and acted as conductors rather than insulators. Washers were painted with Dupont lacquer several times, and reinstalled, tested and operated satisfactorily.

(b) Small copper tubing to lubricator #5 unit of #4 engine carried away.

(c) Silver solder joint between nipple and drain-off line from bearing in lube oil pump on main engine #4 carried away.

(d) Lube oil piping (relief valve to #2 engine sump) ruptured. This is a two inch pipe and it cracked around three quarters of circumference.

(e) Same casualty as (d) above occurred 8 days later on #1 engine

(7) Small piping failures of the nature described above continue to be a constant source of trouble and cause for placing main engines out of commission, frequently for as long as four (4) hours.

HULL

(8) A small air leak, 50 lbs in 12 hours, has developed in #5 air bank.

(8) The fourth stage suction valve (Pc 6-5-13 Mfg. Pr 150-419G) of #2 Hardie Tynes high pressure air compressor failed after 366 hours of operation. It was run that the valve guide had split in two. The broken piece was removed and the jagged edge filed smooth, the compressor then operating successfully.

(9)    It was found when the blank flanges on #3 and #5 F.B.T. were removed to use these tanks as main ballast tanks that the vent gaskets on all four vents had deteriorated presumably through action of the fuel oil to the extent that the vents could not be used. The gasket on 3A was considerably rounded due to bulging and the other gas'ets showed no visible abnormal size. The gaskets popped from their seats when an attempt was made to completely close the valves by hand. The oil resistant qualities of the gaskets installed will be investigated.

RADIO AND SOUND

(10) SOUND: Ref. E.B. Co., Plan No. 2063-44 Alt 5.

Vibration of both the 3C-JK and the 3B shaft while training was experienced at all depths. The vibration and noise increased proportionally with increase of depth or angle on the boat. Repacking of the port piston tubing was accomplished without relieving the condition. It was noted that the lower drift stop roller bearings were not tangent to the lower drift stop roller bearing surface and did not rotate when the projector was trained. It is not believed that this condition alone is sufficient to cause such vibration. The fault may also lie with the outside projector shaft packing whore the shafting passes through the hull, or with improper clearance between the piston and the piston tube packing gland.

ERICLUSURE (A)

1. RADIO
Radio reception was generally good and complete. Difficulty in clearing the PADDLE 301535 of August, 1943 to NPM was experienced due to "skip distance". NPC receipted for and relayed the message to NPM. All other messages were cleared without difficulty other than normal enemy jamming. All messages were transmitted on 8470 KCS.

In compliance with CTF 17's 200927 of July, 1943, while in the area, six hour listen, watch was maintained on 13.63 KCS. On the surface, with signal strength 33 and readability K3. Stare accurately at the varied from light to heavy. While submerged, the lower and upper depths varying from 40 feet to 100 feet with no receptac.

The instructions of CTF 17's 090739 of July, 1943 were carried out daily but no signals were heard on 119 KCS, 9020 KCS, or 1930 KCS, at the times designated therein, i.e., ten, twelve and eighteen hundred (ZEBRA).

Last message sent 070007 of Sept. 1943

Last serial received 24 Y of September 1943

General performance of the SJ radar was excellent due in part to the efforts and ability of YOUNGER, J.D. RITZ, V-6 USNR who serviced and operated this instrument with great skill. The SJ was never out of commission for a period greater than one hour. The longest range noted was on land at twenty miles plus. All troubles were minor and quickly corrected. When the ship is rigged for silent running and available for heating the SJ radar before surfacing, but a permanent connection is desirable.

The SD radar performance was very good. Planes were contacted at distances of fourteen miles and land as far as thirty miles. None other than routine servicing was required. The lower contact shoes required a daily cleaning to prevent corrosion from leakage around the mast.

(N) SOUND

Sound conditions were poor while in the Kumano Nada. The usual "croaker" and "porpoiso" noises were heard but nothing unusual noted. In all attacks, sound did not pick up screws until the range had closed to less than fifteen hundred yards.

In addition to the vibration noted under Major Defects hydraulic oil leaked into the microphone cable on the port sound head and destructive indicator lights and the echo-ranging indicator which controls the dial day of periscope patrol due to frequent use.

It is recommended that power supply for the dial lights and this motor be separated so that it will not be necessary to have the motor running than only dial illumination is desired.

(0) DENSITY LAYERS

No. density layers of note were encountered enroute from Pearl Harbor to Midway, or from Midway to the area to the westward of Kazan Retto. One hundred miles south of Honshu there was slight negative gradients of 76° F to 73° F from surface to 150. feet. In this area it was not necessary to pump when going deep. It was initially necessary to take from 1500 to 2000 pounds into negative, on going deep; and this water would then be gradually blown out as the boat soaked up. Kumano Nada presented an altogether different situation. Predictions could not have been made without the Bathythymograph. Off the entrances to bays and rivers where the water might be exected to result in a heavy boat the opposite was true and much water usually had to be taken in to get to deep depths from periscope depth. Very decided negative gradients were experienced in this area and several layers might be found in going to 250 feet. South of Shiono Misaki and in the limits of the Japan stream layers were experienced at various depths and a gradient of 20° from periscope depth to 250 feet is normal. It was such a succession of layers that permitted this ship to be controlled for about six hours of silent running by moving personnel rather than water to control angle. Here it was not unusual to use 2/3 speed and flood in six to ten thousand pounds to break through a layer. The water off Omai Seki is similar except that it is very changeable and sudden loss or gain of depth is frequent when below 70 feet. In this locality it was generally necessary to take in from ten thousand to fourteen thousand pounds to overcome a negative gradient of 20° F to 250 feet. The water off Diao Saki is more subject to rapid changes. It was in this area that a gradient of 27° to 250 feet, the largest of the patrol, was found. Most of the layers begin at about 75 feet.

(P) HEALTH, FOOD, AND HABITABILITY

The health of officers and men was generally good for a cruise of almost two months duration and of which three weeks were spent submerged during 15 light hours each day. Radar operators and lookouts complained of minor eye strain. Headaches and constipation cases were of normal number. Two electrician's mates were treated for electrical burns of the hands.

The food was adequate.

Habitability was good generally, and air-conditioning of coming tower is a marked improvement.

(Q) PERSONNEL

Officers and men with few exceptions performed routine standing duties in a proficient and commendable manner throughout the patrol. During attacks or while undergoing depth charging and bombing, the performance of all hands was highly commendable.

Limiting factor this patrol: Fuel.

(T) REMARKS

(I) This patrol was colored by two underlying factors: Fuel and weather. We arrived in our area after having expended considerable fuel in six days of high speed running. From that time on, our guiding principle was minimum speed except when actual contact justified the use of fuel. Thus, we "titled" about on the auxiliary engine a good deal. The prevailing glassy sea accompanied by long swells was about as poor a set-up for inshore work as could be imagined.

(II) The Bathythomograph is invaluable. One should be installed at the diving station.

(III) Sonic listening gear would be welcome.

2020 (Y) Sighted Killi Island at a range of 11 miles. Very deceptive appearance on a dark night. Doubtful challenge by flashing white light when passing 7 miles abeam.

: 0545 (Y) Sighted Ailingalapalap Atoll at distance of 7 miles.

: Submerged patrol to eastward during day until 1610 (Y); then proceeded on surface at one engine speed for Mili Atoll.

: 1709 (Y) Surfaced. Nothing in sight. Slow patrol to westward. Position still doubtful.

: 0610 (Y) Patrolling on surface in early morning light, sighted one small and one medium size patrol craft to northward that evidently saw us and turned toward at 0614 (Y). Submerged at this time. Did not attempt to evade on surface because of our doubtful position. No star sights of value on bearings on land for more than 48 hours and a variable current is known to exist.

: 0643 (Y) Small patrol boat in sight (7,000 yards) on starboard quarter. Medium sized patrol craft on port quarter. Both echo ranging.

: 0650 (Y) Patrol boats have again changed course toward and are making a slow deliberate approach. Range 2500-3000 yards. Are not worthy of torpedo expenditure. Rigged for silent running and went to 150 feet.

: 0705 (Y) At 170 feet found the start of a 4° negative temperature gradient. Echo ranging ceased as depth was increased to 260 feet. Possibly due to negative temperature gradient but more probably due to patrol craft commencing a sonic search. Evaded on easterly course.

: 0600 (Y) Sighted land bearing 060° T.

: 0536 (Y) Commenced closing Gun Pass from 10 miles to westward. Two patrol vessels observed a patrol of outside of Gun Pass during the day. Continuous air patrol of one or two single engine, single float, observation (NUFE) planes over Pass during the air activity during afternoon. Smoke sighted a barrage during morning but no ships seen to leave or enter. Fishing boat passed astern within 1000 yards at 1425 (Y) without making contact.

Triangular patrol to westward during night.

November 6, 1943

: 0605 (Y) Submerged 10 miles of Gun Pass after observing searchlight display from Enuburi and Kwajalein Islands. Since there was a fair chop, decided to close reef between Enuburi and Kwajalein to observe shipping in the anchorage. At 0920, having closed to about seven miles of anchorage, observed two medium freighters at anchor, one making considerable smoke. At this time three "catcher" patrols off the reef came uncomfortably close, all echo ranging. Evaded at periscope depth to the south-westward. Having cleared them at 1130, resumed course to close anchorage. Soon thereafter, sighted a patrol vessel similiar in appearance to our medium sized coast guard cutters standing slowly to the northward toward Enuburi. At this time observed that the smoking freighter in the anchorage had begin to move northwestward toward Gun Pass.

Sha cleared the pass at 1330, stood southcoastward close along the reef, a good five miles out of our reach, and disappeared to the eastward. Had we succeeded in gaining our objective off Kwajalein Island, we should have been right on her track. Through-out this entire day the periscope was never raised without seeing at least one plane and at least one patrol boat.

1606 (Y) Sighted "Mavis" patrol plane apparently returning from patrol to southward.

1728 (Y) Sighted 3 unknown type bombers heading southwest in formation.

1943 (Y) Dove for plane with red and green side lights burning.

2110 (Y) Dove for plane with white running light burning.

Patrol 20 miles to south east of Kwajalein Island until 0113 (Y) of November 7, 1943.

November 7, 1943

0113 (Y) Set course for "Mili Atoll. Lat. 08-40-N Long. 168-30 E

0340 (Y) SJ radar contact at 15,500 yards bearing 125°. Commenced tracking on course 280° T. Convey (1 large, 1 medium, 2 small pips on SJ) speed 10 knots, possibly "wiggling". Sighted two ships at range of 10,000 yards at 0445 (Y). Full moonainia-cloudless sky prevented a surface attack. Swell prevented 40 ft. radar approach, so drew ahead of convoy and dove at 0603 (Y) for submerged periscope approach. At 0645 (Y) could make out loose formation of six small ships; one 3500 ton freighter similiar to TOKYO MARU, page 222 of ONI 208-J, one small, old tanker of about 1500 tons, one inter-island "cocoanut" boat, one sea-going tug, two PC type escort and one (RUFE) plane. Decided to attack freighter. At 0714 gained position 20° on starboard bow, range 3500 yards and dead ahead and close to starboard escort which was echo-ranging. Dropped to 90 feet to let escort pass over us, meanwhile turning right to a 120° track. The escort failed to pass over, but went past close on our port side. Return to periscope depth at 0725 revealed that target had turned away, presenting a 150° track, torpedo run of 3500 yards. Decided not to shoot.

0750 (Y) Resumed course for "Mili Atoll.

1227 (Y) Surfaced and continued course for "Mili Atoll at 2 engine speed throughout afternoon. Clear weather until late in evening.

Nov 8, 1943

Closing 'Mili Atoll for a position 10 miles north of Tokawa. Entrance Poor visibility: Frequent rain squalls, general distribution of low lying clouds.

0645 (Y) On surface attempting to make landfall during conditions of poor visibility, sighted unidentified type plane coming out of low lying clouds 2-3 miles on port quarter. Dove and received small but close bomb in vicinity of after torpedo room when passing 60 feet. Broke guage glass and light bulb, stopped clock, knocked off paint chips, etc, but no serious damage done.

Rain and heavy swell from S.E. continued throughout day. Patrol located north and northeast, uncertain of position.

0930 (Y) Heard two distant explosions, possibly depth charges. Nothing in sight.

Fixed position by star sights at 2124 (Y) as sky cleared and proceeded for morning position - 20 miles west of 'Mili Atoll. Heavy swell from S.E. continues.

Nov 9, 1943

Patrolling submerged, 15 miles west of 'Mili Atoll. Heavy swell during day. North-eastly set.

1700 (Y) Sighted smoke bearing 1470 T. Later developments showed that smoke sighted at this time could have been either patrol boat making preliminary sweep to seaward of entrance or a steamer getting underway in the lagoon.

1910 (Y) Surfaced and sighted two columns of smoke bearing 1760 T distant 15 miles. Flashing light overhead indicated presence of air escort. Very bright moonlight, few clouds in sky, excellent visibility.

2007 (Y) Changed course to east to make landfall.

2015 (Y) Made landfall on 'Mili Atoll. Set course for Jaluit Atoll to get on track about 15 miles ahead of columns of smoke whose bearings indicated travel in that direction. Heavy swells from S.E. would have prevented an attack from 90ftcradar depth.

Nov 10, 1943

0035 (L) Posi tion Lat 3 - 37 N Long 167 - 10 E. Special mission considered complete. Set course 33° T for position at daylight November 26 (L) on line between Truk and Kwajalein, 30 miles N.W. of Wjae Atoll.

— page 62 —
0517 (L) Submerged in position Lat. 09 - 31 N Long 165 - 04 E. Slow patrol north and south.

: 0634 (L) Sighted two Zero float planes that appeared to be making a sweep to westward. One plane seen to return on easterly course. These planes were of different type than the observation planes previously sighted in this area and could have been cruiser based.

: 1637 (L) Submerged until 1807 (L) when within 40 miles of Eniwetok.

: 2116 (L) Changed course to make landfall on Eniwetok and then dive in position 5 miles south of Wide Passage.

: 0800 (L) Sighted the masts and stack of freighter at anchor off south end of Island.

: 095 7 (L) Sighted RUPE type plane patrolling over Parry Island.

: 1030 (L) Changed course to 045° T.

: 1103 (L) Sighted twin float plane bearing 057° T and patrolling to west.

: 1113 (L) Sighted tops of a destroyer bearing 057° T over a heavy swell from the east. Manned battle stations.

: 1117 (L) Sighted tops of several ships that soon showed themselves to be four heavy cruisers in column screened by six destroyers. C ours 265° speed 16 - 17 knots. True bearing of last cruiser 070-30° i; range 11,000 yards.

Commenced approach and closed to a minimum range of 6,500 yards or last cruiser. Broke off the approach when angle on the bow of last cruiser was 135° Port, bearing 357° T.

: Cruiser column did a ship's right about 60 degrees just prior to turning again to west for entrance. Screening destroyers patrolled ahead and on either bow of column and then swept back along column as cruisers made smart entrance into lagoon through East Channel.
: Nothing in sight by periscope. Patrolling to northward toward entrance.
: One destroyer noted to be at anchor near south end of Parry Island. Cruiser or destroyer masts observed near northern end of Eniwetok Island. No other vessels in sight in lagoon.
: Sighted masts of ship bearing 252° T, off southern end of Eniwetok Island and close in shore. Contact turned out to be a 10,000 ton tanker of the NIPPON MARU class, page 263 of ONI 208-J accompanied by two destroyers, one on the starboard beam or ahead and one on the starboard quarter. Tanker on course for East Channel of Eniwetok Atoll and one mile off the reef. Came to course for entrance and ran at high speed when possible, but tanker and destroyers entered lagoon at 1513 (L) with the least range having been 8,000 yards.
: Continued patrol off East Channel on a southerly course and made rectangular patrol at night to south east of Atoll, returning to position 11 miles east of East Channel for morning dive.
: Our fuel supply is such that we can expect to make Johnston Island with no safety factor. However, the situation here demands remaining to attack the force in sortie from Eniwetok, or at least, failing an attack, to dive information of its movements.

November 29, (L) 21943
: 0521 (L) Submerged 11 miles bearing 690° T from East Channel. Commenced north - south patrol, allowing 0.9 knot current on set 300° T to carry us toward the Atoll. Chose position 11 miles off entrance in belief that this would give a better chance for torpedo attack during cruiser sortie than if we were closer to channel entrance and more hampered by destroyers making preliminary sweeps. Also, north or south course are the only courses upon which depth control is fairly good.
: 0700 (L) First of rain squalls that passed over periodically during forenoon. Heavy swells from the east continue and periscope visibility is poor.
: It is believed that the 4 cruisers and 6 destroyers left Eniwetok during the morning and were not sighted or heard because of heavy swells and rain squalls.

— page 64 —
1155 (L) In position 7 miles off East Channel sighted tanker and two destroyers of yesterday at an initial range of 9,200 yards. There was one destroyer on the starboard beam of the tanker, and another on her port bow, both echo ranging. We gained position for attack on a 90° starboard track, range 2700 yards, and dead ahead of the starboard screen. She must have made sound contact, for at 1225 (L) there was a depth charge explosion, evidently a warning. That an air patrol spotted us under the sea conditions prevailing is most unlikely.

1226 (L) Fired five bow tubes with a total spread of 6°, average track 45° starboard, torpedo run 1850. After we had fired our first torpedo, the target started a turn toward. Applied a total change of target course of 25° during firing. Unfortunately, after the second shot, the periscope went under, so that the bearing could not be kept correct for the last three torpedoes. Torpedo runs not observed. Starboard escort headed directly toward and speeding up at range of 2000 yards at time periscope went under.

1 minute and 43 seconds after firing last torpedo there was heard a very loud explosion that sounded like a torpedo hit. This was followed closely by a second similar explosion. Forward torpedo room and conning tower personnel agree that there were two very probable hits.

These explosions were followed soon afterward by a series of close depthcharges as PADDLE went to 250 feet and turned left. No damage of consequence.

At 1232 (L) depth charging ceased and 2 destroyer screws and echo ranging were heard, one on starboard quarter and one on port bow. During this period of relative quiet, definite "crackling" noises were heard by conning tower personnel, similar to those heard after other ships have been hit.

PADDLE evaded at 2/3 speed on southerly courses while 2 destroyers echo ranged until 1400 (L). One destroyer echo ranged to northward until 1500 (L). Last depth charge at 1312 (L). Soon after last depth charge sound periodically reported rain squalls passing overhead that may have helped evasion.

1714 (L) Nothing in sight. Secured from silent running conditions and commenced reload.

1915 (L) Surfaced and cleared area to southward.

(D) WEATHER
The state of the weather found in both Southern and Northern Marshalls was generally as described in the Sailin, Directions for this area. Thoro is a tendency for the skies to become heavily overcast at sunset and dawn which makes taking of star-sights difficult. Rain squalls are frequent and a change of wind from the usual S.E. to S.W. indicates the coming of a two or three day period of generally poor visibility, heavy cloudiness, and passing rain.

The wind usually picks up at dawn and dies down in the evening, resulting in smooth seas during the night and sufficient white caps for good periscope weather during the day as a general rule. Consistent strong winds from the East and Southeast build up long, heavy swells that make depth control difficult and reduce the range of periscope visibility very considerably.

(D) TIDAL INFORMATION
No data obtained on this raid fall of tides or tidal currents in the Marshall Islands area. Currents off shore and between Atolls of this group are generally as described in the Sailin, Directions; i.e., easterly in the Southern Marshalls and Westerly in the Northern Marshalls and varying from 0.5 to 2.0 knots. The easterly current to the south is more pronounced than the westerly current to the north, and in any part of the area when approaching an Atoll there may be an unexpected and variable north or south component to the east-west current, usually in a direction away from rather than toward the Atoll.

(E) NAVIGATIONAL AIDS
No new navigational aids in the Marshall Islands were observed. Taints of various islands on the Atolls give good cuts except for the east side of Jaluit Atoll. SJ radar had difficulty in picking up any land, sometimes at ranges of 4 or less miles. Islands are usually well to ranges of 6-8 miles on dark, clear nights. Charts appear to be accurate.

1. MINES
No mines or indications of minefields noted. Several of the escort and patrol vessels encountered appeared to be suitable for mine-sweeping use.

2. ANTISUBMARINE MEASURES AND EVASION TACTICS.
There is not much surface patrol activity in the Marshall Islands areas except close to Atoll channels. Increased patrol activity indicates probable passage of bi ship traffic. Air patrol is active although usually confined to the coast also. All large ships or convoys have constant air patrol during day and moonlight nights.

Ships making passage between Atolls make radical and frequent changes of course. Small, non-descript vessels are roused about ships worthy of torpedo fire and escort vessels of a converted type are plentiful.

Escorts and patrols use echo-ranging and these waters appear to be favorable for echo ranging. One small negative temperature gradient was observed north of Mili Atoll. All other locations gave a straight line on the bathymetrograph card. Sound conditions are good. Two patrol vessels conducting a search for PADDLE were heard to communicate by underwater sound for a short time.

Japanese RDF stations appear to be alert, and it is possible that PADDLE SD radar was DF'd one moonlit night 10 miles south of KWAJALEIN. Night flying planes appeared to be searching for us.

Ships leaving or entering an Atoll stay very close (one mile) off the reef so long as possible.

Two destroyers escorting a 10,000 ton tanker out of East Channel, Enewetok Atoll were alert and very much on the job. At a range of 2,000 yards, one escort either made scud contact or sighted periscope (heavy swell and choppy surface) and dropped a warning depth charge just before PADDLE reached firing point. Close depth charging followed soon after firing, followed by super sonic search.

Evasion tactics consisted of silent running, when confronted with sonic search and higher speed with turns away when opposing super sonic search.

(K) MAJOR DEFECTS AND DAMAGE
Three days after leaving Submarine Base, P.H., during a routine drill dive an excessive vibration of the periscope shears in particular and of the entire ship in general was noted at speeds in excess of 3 knots submerged.

— page 75 —
1 0859
Subject: U.S.S. PADDLE - Report of Second War Patrol.

(K) MAJOR DEFECTS AND DAMAGE CONT'D

At 2/3 speed (80 rpm) the vibration of both periscopes is such as make the taking of an accurate observation practically impossible.

During the refit period new lookout platforms, port and starboard, were mounted on the periscope shears and the normal lookout platform, stanchions, and life lines removed. The side plating on the periscope shear supports was cut down two feet from the top. These alterations are a possible source of the vibration but are no trouble during the training period.

Just prior to leaving on patrol the starboard propeller was damaged by a boat leaving from along, side and the damage was repaired in place during an emergency deck. The propeller was not balanced and is also a possible source of the vibration, although stopping the starboard shaft does not reduce the vibration.

It is possible that the starboard stern plane may have been damaged so as to cause the vibration although there was no evidence of this at time of docking.

The vibration is less at deep depth and disappears when a large up angle (8-10 degrees) is put on the boat.

It is considered very essential that the cause of this vibration be determined and eliminated during the coming refit period.

(L) RADIO

Reception was in general good and complete. During the first few days of HAIKU broadcast reception was poor during most of the day and impossible for about an hour around sunrise. With the addition of the 4525 kcs band and an increase in power on all frequencies reception was greatly improved.

PADDLE's 291158 of October 1943 was relayed to NPM by NZ because interference made it impossible to contact NPM. Due to atmospheric conditions PADDLE's 030757 of November, 1943 was jarred in transmission and was not receipted for by NPM. All other messages were cleared without difficulty. All messages were transmitted on 8470 kcs a total of twenty three (23) messages were transmitted.

First message received was Consubpact 180748 of October 1943 serial 672. Last message received was Consubpact 081257 of December 1943, Serial 4.

(M) RADAR

Performance of the SJ radar was excellent. Maximum range was 18,500 yards on a small freighter. No signals were reflected from the atolls except on one occasion contact was made on land with an elevation of 21 feet at a range of 11,000 yards. There were no major failures and the longest period it was out of operation was one hour.

- 22 - ENCLOSURE (A)

— page 76 —
U.S.S. PADDLE - Report of Second War Patrol.

(M) RADAR CONT'D

Performance of the SD radar was good though on a number of occasions planes were sighted from the bridge before radar contact was made. Maximum range was 34 miles on a large flight of planes. There were no major casualties and the SD radar was never out of commission for over forty five minutes.

(N) SOUND GEAR AND SOUND CONDITIONS

Sound conditions throughout the Marshall Islands varied from good when close to the atolls to excellent when clear of land. Maximum ranges were 10,000 to 12,000 yards with no major target closing to less than 8,000 yards without sound contact being established.

No maintenance difficulties were experienced.

(O) DENSITY LAYERS.

(1) Oct 31, 1943, 1830 - 2330 GCT
   Lat 06°-30'-00 N
   Long 170°-45'-00 E
   Surface temp. 78°0, isothermal to 180 feet, then negative gradient to 750 at 300 feet. Layer seemed effective for escaping echo ranging, which faded from 2 vessels while passing 190 feet.

(2) No other density layers or negative gradients were found in Marshall Islands area.

(P) HEALTH, FOOD, and HABITABILITY

The health of crew and officers was generally good with the usual cases of constipation and headache following days submerged. Bridg and radar watch standers suffered from eye strain.

Food was entirely adequate and well prepared.

Habitability was better than average due to more than average amount of time spent on the surface.

(Q) PERSONNEL

The performance of all officers and men was highly commendable.

Horizon fair with low dark clouds; very clear overhead.

: 0011(I) Moonrise. Beginning of last quarter.

: 0035(I) Two targets faintly in sight from bridge. Range 16,750, 0670T. They are large ships, smoking quite steadily and heavily. This is target group 'I'. Two large and one small pips on radar.

: 0100(I) Radar now has second separate target group. One large and one small pip on bearing 0600T, that seen to be closing target group 'I'.

: 0115(I) Indications of two more small vessels on radar. One in target group 'I'. One between target groups. Five ships in sight from bridge. Moon now above dark clouds and visibility very good. Smoke from largest ship and hull outline can be seen in 'I' periscope. Turned toward and steadied on 0700T to examine attack.

: 0120(I) Submerged to radar depth. Range to largest target 11,000 yards. Range to leading escort 9,500. Second target group has joined first. Three large ships in sight by 'I' periscope on course 2300T, relative line of bearing 1400 from right hand ship which is the largest and closest of targets.

: 0130(I) Destroyer picked up in periscope ahead of second target.

: 0132(I) Commenced periscope depth approach. Range to largest target 7,940 yards, 'Rigged for silent running, except planes and steering. Closing at 5 knots on course 1300T for 90 starboard track on target 'I'. Angle on bow 300. Intend firing bow tubes at target 'I' and stern tubes at target '2'. Destroyer ahead of target '2' will pass astern.

— page 90 —
0147(I) Target formation zigged toward, angle on bow of target at 1/2
    is zero. Now target 1/4 course 245°, range 2,600 yards.
    Came right to 170°T for storm tubes shots at targets 1/4
    and 1/2, 750° port track.

: 0152(I) When steadied on new course 170°T the general picture was as
    follows: Target 1/4 bearing about 200°T and almost in position
    for a zero gyro an 1/2 shot. Targets 1/2 and 3 on a line
    of bearing 120°R from target 1/4, one ship length of water
    between storm of 1/4 and bow of 1/2. Some between 1/2 and 3.
    1/2 closer to 1/4 than 1/3 is to 1/2. Leading destroyer has
    gone by astern and is well ahead of target 1/2 on PADDLE
    starboard quarter. Second destroyer beyond and slightly
    ahead of target 1/3. One small escort soon astern of
    formation. Second small escort indicated by radar not yet
    sighted.

Target 1/4 is the largest of the three, and all are big ships.
Target 1/4 similar to PLUTO NANT, page 96 of ONI 208-1,
9419 tons.

Target 1/2 is a tanker similar to SIX PEDRO NANT, page 275 of
ONI 208-1, 7,300 tons, exact that she has a small goal-post
mast near bridge. She is not heavily loaded.

Target 1/3 is the smallest of the group; an unidentified AK.

Destroyers are HATSUKI Class, page 72 ONI 14, 1368 tons,
8', 9" draft.

Small escorts are of converted trawler type.

Except as to general type, which can be made out at this time,
those identifications are based on later observations.

0154(I) Commenced firing storm tubes. 1/10 and 1/9 at target 1/4,
torpedo run 900 yards; gyro 20 left, first to hit under
bridge, second with 20 right spread on point of aim 10°T.

— page 91 —
0156(I) Missed target #1. One hit at in target 2. 1 and leading DD turned toward immediately after torpedo hit. 3 turned away. Per DD turned away. 2 sounded to slow and go down somewhat by stern. Did not immediately change course. P.D.D.L. swinging right to course 220°T.

: 0158(I) Several depth charges - not close. Much promiscuous gun firing.

: 0200(I) Target #1 and leading DD have steadied on course about 130°T. 1 is sharp on starboard bow, DD is to right of her, and 2 has turned toward. 3 is on course about 080°T and passing astern. Per DD has come around 3 and headed toward P.D.D.L. Small escort near 2 headed toward. Small escort that was astern of formation not seen at this time.

: 0201(I) Obtained good set-up on #1. Angle on bow 90 port, staid motor range 1050 yards.

: 0202(I) Checked set-up on target #1 and commenced firing 4 bow tubes. Gyro angle 200 1 at, divergent spread of 2 between torpedoes, point of aim 10°T, depth set at 10 feet, speed 12 knots.

: 0203(I) One hit forward of bridge, one hit aft of bridge. Third hit heard but not seen due to periscope search. Tremendous shot of flame enveloped forward port of 1 when first torpedo hit. She immediately listed to port.

: 0204(I) DD ahead has turned toward, slightly on P.D.D.L. port bow. Angle on bow 2 zero. Obtained set-up. 2 headed toward on starboard bow. Small escort near him and headed toward. DD on port quarter headed toward. 3 still headed away.

: 0205(I) Checked set-up on DD ahead and fired two for tubes set at 6 feet, spread 2° left and 2° right, torpedo run 1000, gyro 9° left, speed 16 knots.

: 0205(I) One hit in destroyer. DD took list to port and stopped. Started periscope search to right and found target 2 very close aboard and sharp on starboard bow. Nothing but hull and bridge seen in high power. Went to 100 feet so as to avoid collision. Believe PADDL had been sighted.

: 0205-0225(I) Very loud crackling and breaking up noises heard all around. Various compartments reported metal striking hull, particularly aft. Many minor explosions that were heard both on DP gear and through hull that sounded as if magazin.s were exploding. The breaking up noises are the loudest experienced hands have ever heard.

— page 92 —
0205-0225(I) Received pattern of scovoral depth charges from small escort (Cont'd.) heard coming in from starboard.

Recoived pattern of scovoral depth charges from DD heard coming in on port quarter.

PADDLE swinging slowly left to 010°T, running at 2/3 speed.

0225(I) DD and escort heard milling about astern and on both quarters. No target screws hoard. Breaking up noises have almost ceased.

Believe that the large passenger-cargo ship and DD hit have sunk and that target 3 and one small escort are getting clear on course 060°T.

0225-0240(I) DD and escort are searching generally astern. PADDLE swinging left slowly to 326°T at 150 feet. Escorts are fairly close and thin gradually more distant.

0241(I) Six depth charges - not close.

0247(I) At periscope depth. Target 2 apparently stopped, bearing 1450T, distant about 3,500 yards. Small escort near and circling. DD bearing about 200°T. No other ships seen. Visibility excellent. Sound conditions excellent.

Started opening range to surface on course 345°T.

0321(I) Radar range on 2 is 4,300 yards. Small close pip on PPI on port beam closing. Nothing in sight, but range is closing, and visibility is not particularly good now due to moon clouding over. Went to 100 feet.

0337(I) At periscope depth. Cripple in sight. Escort and DD not seen.

0343(I) Surfaced on course 000°T.

0344(I) Range to cripple 9,200, bearing 165°T. Commander rolled and started circle around cripple group at range of about 13,000 yards while tracking. Decided to put in short battery charge and obtain position to west of cripple. Group for periscope attack at daybreak. Visibility now variable.

- 10 - ENCLOSURE (i)

— page 93 —
0344(I) Plot shows cripple is moving slowly on erratic courses. DD is circling cripple generally at 5,000 yards, but on erratic courses and at varying speeds averaging 12 knots. Cripple periodically is almost obscured by clouds of heavy black smoke. DD continues to smoke, as both did before and during first attack.

0454(I) Cripple bears 0740, distant 10,070 yards. Small escort and DD can be seen nearby from bridge.

0456(I) Submerged on course 0700T, and commenced approach. Radar plot shows we will be in good position at daybreak.

0515(I) Rigged for silent running except planes and steering.

0600(I) Excellent visibility except in vicinity of target group, which is obscured by only rain squall in area. Sea very calm and glassy.

0626(I) Own course 3400T, crippled tanker bearing 3420T, range 4,000 yards. Small escort on the left. DD to the right, well out and headed north. Target angle on bow now 500 port but changing radically. Sunrise. One plane seen over tanker.

0640(I) DD speeded up and is making a circle around to left. Sound has slow heavy screws or pumping on tanker bearing.

0644(I) Angle on bow of tanker now1800, range 2,500. DD on steady course coming slowly down his port side. Large triangular piece of wreckage sighted ahead and to right of tanker.

0652(I) Set-up on DD makes him much better target than tanker. Deadlock to sink DD with four bow tubes and then finish off tanker. Small escort near tanker.

0656(I) Checked set-up on DD carefully and commenced firing 4 bow tubes set at 6 feet. Torpedo run 2050 yards, gyro angle average 180 left, torpedo track angle average 37 port, spread 120L, 120R, 30R, 30L, point of aim MCT, speed 4 knots. Bearing checked during firing very nicely, but no hits. Bo-lieve the two that should have hit ran under. PDDLE swinging left and making ready stern tubes. DD did not change course or speed up until 2 minutes after firing. Escort near tanker has turned forward however and is closing. Intend firing stern tubes at tanker, whose angle on bow now is about 120 starboard, but depth control is poor and the periscope is going under.

0700(I) At 69 feet. Escort on starboard hand closing rapidly on steady bearing. Ordered 150 feet, and tubes 15, 6, 7, 3, 9, 10 secured.

— page 94 —
0701(I) First depth charge of a close pattern of 10 from the escort.

: 0704(I) Destroyer coming in from port six o'clock.

: 0705(I) Received uncomfortably close pattern of 8 depth charges from destroyer. P.D.D.L.S. sinking left slowly at 2/3 speed, 150 feet.

: 0740(I) Steadied on 250°T at 2 1/2 speed. DD and an all escort soon to be searching pretty well astern. Started up slowly. Tube outer doors had been closed at about 100 feet and various presursors from 0 to 40 pounds remained. Still very slowly at 2/3 speed, 150 feet.

: 0754(I) Periscope depth. Tanker with DD to right is about 3,000 yards away bearing 000°T, only on bow zero or 180°. Small escort to left and somewhat closer. One plane over tanker. Tanker shows smoke from stack. DD smoking as usual. Sea still very calm and glassy.

: 0755(I) While taking second look received close bomb from plane which must have been very nearly overhead.

: 0758(I) Soon after taking third look received a closer bomb. Our light camouflage is not helpful at this time. Went to 150 feet after taking a fourth look and noticing that both escort and DD had turned toward and were definitely closing.

: 0826(I) First echo ranging heard at this time from 030°T. Found an excellent negative gradient at 230 feet. Continued on base course of 250°T with echo ranging alternately closing and then drawing away. Light searchers heard at slow speed when echo ranging loudest, but true bearing is hailing off to the right slowly.

: 0920(I) Single depth charge or 1/2" fairly close. No echo ranging for 15 minutes before or after this explosion.

: 1005(I) Pattern of 6 rapid depth charges or bombs - not close.

: 1045(I) All quiet except for distant, searching echo ranging at about 070°T. Started back to priscope depth.

: 1055(I) Sighted smoke and tops of DD at 071°T. Plane overhead of DD. No sign of small escort or of cripple except that a smoke cloud is to left of DD and might be coming from tanker. Sea still very calm and glassy.

True bearing of smoke changing very slowly to right. PUDDLE changing course to right to keep smoke in sight. Planes sighted infrequently. Intend to attack again at dark.

1425(I) Smoke last seen on bearing 086°T. Cripple moving slowly to northeast.

1648(I) Smoke sighted bearing 095°T closing.

1700(I) New contact is a small steamer of about 600 tons making 7 knots, but not believed worthy of torpedo fire. Bow indicates possible use as not tender or for salvage work. Let go by 2500 yards ahead.

1745(I) Small vessel disappeared on course 315°T.

1931(I) Surface on course 090°T and commenced search for tanker. Maximum area covered using four engines when not charging. Numerous radar contacts on wreckage and floating objects during night, but not to fear.

0115(I) SJ Radar contact bearing 1590T, range 2350 yards.
    Lat.: 03-59-00S, Long.: 126-17-00E. Plot shows high speed. Similar contacts were made at 0120, 0137, 0150.
    Contacts were picked up on either bow or quarter at 2,700 to 6,300 yards, closed rapidly and were soon lost. One plot shows speed of 36 knots and good torpedo approach indicates possibility of radar equipped P.T. boats but this is doubtful, since it is believed that any high speed boat would have been sighted at close range. See reproduction of plot and comments under "MDR Section of this report." Named the RBH and searched. Heard uncooperative voice communications between what seemed to be two operating units on 8700 kcs.

(C) TEATHER

The weather in the area was for the most part very uniform. It is as described in the Sailing Directions. Early evening skies were usually overcast accompanied by glassy calm water. Early morning usually brought a light wind with rippled water until about mid-morning. Rain squibs; were continual and frequently accompanied by electrical displays. Seas were characteristically calm with light occasional swells. Wind was predominantly northwest until about 19 April then predominantly northeast. Barometer steady at about 29.5.6 except for the minor daily variations. Mean temperature while on the surface was 78°F. Heavy clouds cover most of the mountain peaks at mid-morning, and continue until sunset daily. Many of the ravines and valleys on the islands were constantly in fog or vapor and appeared to be very damp. Good periscope water is not to be found in the area at this time of the year. Visibility was uniformly good, but interrupted by the frequent squalls of short duration.

(D) TIDAL INFORMATION

The tidal information included in the Sailing Directions while general is essentially correct. Tidal currents in the proximity of passes or islands are sometimes strong and unpredictable. In the northern Molukka Sea a general northeast set was experienced. In the Ceram Sea a general north-north-east current of between 1.0 and 1.5 knots was found. In the vicinity of Doi Island the currents averaged about 1 knot in a northeasterly or southwesterly direction with no predictable time of changing from one to the other. In the entrance to Horotai Straits a current of 1.5 knots direction 2880T made steering difficult while submerged. The currents near BARA BAY were generally to the westward, 3.5 knots; while a set towards the shore was experienced along the west and southern coasts of BURU ISLAND. The current in the vicinity of SAMANA ISLAND and LIPUMPULA ISLAND was 1.5 to 2.0 knots in an east-north-east direction. Heavy tide rips were noted here. Then approaching islands or passes a sudden variable current may be found that is unpredictable from hour to hour.

(E) NAVIGATIONAL AIDS.

No new navigational aids were found. No navigational lights were sighted. Peaks and tangents served adequately and appear to be accurately charted. Tangents should for, the most part be used with caution as many are low and unreliable, except when very close. The morning diving position was usually determined by radar. In early morning the islands are usually clearly visible for great distances, but by mid-morning most of the peaks are in the clouds.

TARGET DATA - DAMAGE INFLICTED

Description: Japanese AP-AK similar to RAUKYO HAKU (9419 tons); with a large AO similar to SAW PEDRO HIRU (7300 tons), and a medium sized AK on a line of bearing 1200R from AP-AK, one ship length of water between stern of first and second. Convoy escorted by two destroyers of HATSUHARU CLASS (1368 tons) and two converted trawlers.

Ships sunk: 9419 ton AP-AK. 1368 ton DD.

Ships damaged: 7300 ton AO (possibly sunk).

Damage determined by: 1(a) One torpedo was seen to hit at the AO and she seemed to slow and go down by the stern. She did not immediately change course as did the other vessels of the group. Last seen in same vicinity moving very slowly to northeast thirteen hours later. Thorough radar search of area later failed to dislose target.

1(b) One torpedo was seen to hit the AP-AK forward of the bridge, one aft of the bridge and a third torpedo was heard but not seen due to periscope search. Much flame enveloped forward part of the ship and she immediately listed to port. Heavy breaking up noises were heard on sonic listening gear and through hull. Target was not in sight or within radar distance 42 minutes later.

1(c) One torpedo was heard to hit in destroyer and immediately thereafter she was seen to take list to port. Sound operator heard both torpedoes' screws and those of DD. One torpedo was running to left, and one in line with DD's screws. After torpedo explosion the screws of DD stopped and only one torpedo was heard running after hit. Loud breaking up noises were heard through hull and sonic gear accompanied by minor explosions. This target was not in sight or within radar distance 42 minutes later.

(J) ANTI-STUBBORN MEASURES AND EVASIVE TACTICS

A general air patrol was not observed in this area. Reconnaissance aircraft was seen over MOROTA. STRAIT once. A single patrol craft was once seen entering MOROTA STRAIT at high speed. A total of nine contacts were made with medium size s.ilin boats. It is possible that some

(J) ANTI-SUBMARINE MEASURES AND EVASIVE TACTICS (CONT'D.)

of these are used for anti-submarine work. A single patrol boat was encountered in OMNI STRAIT after leaving the area.

The convoy that was attacked on 13 April had an unusual number of escorts, two destroyers and two small escorts for three targets. They were not echo ranging prior to the attack and their speed is believed to have been too high for efficient listening. The first depth charges dropped indicated that the PADDLE was undetected prior to the attack. Seven minutes then elapsed before the next depth charge attack. Evasion after being forced down to avoid collision consisted of "running silent" at 2/3 speed at 150 feet for a short time, putting searching vessels at term, and then coming to periscope depth. Prior to the second attack the PADDLE moved into firing position without being detected while the destroyer and escort were making slow speed. There was still no echo ranging as they circled about the crippled tanker. Plane coverage arrived between the first and second attack. The arrival of planes and daylight seemed to improve and bolster the surface vessels' attacks. Aircraft bombing was fairly accurate and it is believed that PADDLE's outline was seen by the plane before the periscope was raised. No echo ranging was heard until two hours and twenty minutes after the second attack. Then echo ranging started we went deep and found an excellent negative gradient at 230 feet. Evasion consisted of running at two thirds speed and making changes of course with 100 rudder along general base course of 250°C when echo ranging grew near.

(K) MAJOR DEFECTS AND DATA

1. MAIN ENEMY FLEET COUPLING

Number 3 main enemy fleet coupling, housing, vibrated slightly loose and dropped enough to cause rubbing. Out of commission 11 hours.

2. MAIN FIRE HEAD ROLES

Following head-bolts broke: Two inner bolts on 1 unit, 4 engines. Replaced. Upper left bolt on units 20, 10, 12, 13 of 3 engine. Replaced. GM plan N25300, piece 522. These bolts had to be individually drilled and tapped out. Easy-out stud removers failed to remove the. Average time per bolt - 12 hours.

3. PORT MAIN SHUTTING

Very pronounced shaft squeal, port shaft, at all speeds in excess of 65 RPM's surface and submerged. First heard on JP year 19 days after entering area.

4. KLEINSCHMIDT DISTILLER
Number 2 distiller developed salt water leach in coil bundle. Repairs not undertaken.

5. HIGH PRESSURE AIR COMPRESSOR
Valve gas fourth stage suction valve broke and small fragments entered fourth stage causing damage to top of cylinder head and piston bolt. Bolt filed smooth, 1/16" head gaschet replaced by 1/32" gasket. No scoring of cylinder walls resulted. Compressor reassembled and gave normal operation. No noticeable drop in pressure.

6. AIR CONDITIONING PLANT
The compressor unit of number two air condition plant did not operate properly throughout the patrol. Continual maintenance kept it running with a suction temperature of 54°F (20° high). Inoperative expansion, constant pressure, suction and discharge valves are the suspected troubles. High temperature and humidity did not permit putting the unit out of commission for the length of time necessary to effect complete repairs.

ENGINEERING (ELECTRICAL)

7. MASTER GYRO COMPASS
Automatic speed correction follow-up in master gyro failed due to burning out of small movable contact. Spare made from TDC spares and proved satisfactory. Arma dwc. #50560-D, piece #50353-2.

8. MAIN MOTOR BEARINGS
Number 3 main motor after-bearings wiped shortly after diving on April 1. All temperatures had been normal during the night's run at standard speed. Cause believed loss of lub oil due to air binding at this, the high bearing. Shaft was braked and bearing renewed. Similar casualty occurred to main motor after bearing on April 23. Bearing removed, scraped and replaced. Not badly wiped. Out of commission 5 hours each time.

9. AUXILIARY GYRO COMPASS
Auxiliary gyro south rotor bearings burned out, resulting in roughened and flattened pivot bearings. No spares carried.

— page 115 —
10. PERISCOPE HOISTING GEAR

Number 2 periscope hoisting motor brake grabs. Readjustment allows satisfactory operation until complete repairs can be made. Both periscopes: upper and lower limit switches are continual source of trouble due to sticking. Continuous attention is required to insure proper operation. "Lower" button switch on #2 periscopes developed short circuit, causing periscope to lower itself. Switch replaced.

11. BATTERY AIR FLOW METERS

Battery air flow meters have become erratic. Previous similar trouble has been worked on by ship, tender, base and navy, "ard without permanent success.

(L) RADIO

The performance of the radio equipment, though no major failures were encountered, was definitely below expectations. On departing Pearl tests were conducted on the new audio modulator at 3155 kcs. with a B-24 and only intermittent contact with the plane was obtained. After several minutes of fading in and out contact was lost altogether and never regained. No derangements could be found in the gear.

The main source of trouble was a leaky antenna trunk, resulting in extremely low ground ratings on the antenna and consequently, difficulties in reception. Prior to departing Pearl the antenna trunk was fitted with new gaskets and given positive pressure tests but the source of leakage persisted. The average resistance to ground of the port antenna was 100,000 ohms while the starboard antenna average reading was 30,000 ohms.

Reception of NPI was fair to good until April 1 when considerable jamming from a powerful station began. No serials were missed while guarding NPI; it was a serious problem. Only one transmission was made while guarding NPI and this was finally given to NPG on 8490 kcs. to relay after much jamming, believed to be originating at "Take Island." This was on March 28. Guard was shifted to VIXO at 0000 on April 4 and difficult reception was experienced for the first two days. Reception of VIXO in general was only fair and from April 24 to 26 was extremely poor. On April 25 VIXO was tuned in on the RBH and was used to supplement VIXO for two days.

Subject: RADAR.

The appearance of a permanent pseudo-echo at 1470 yards on all bearings was the only major difficulty experienced with the SJ Radar during the entire patrol. This pseudo-echo resulted from spurious oscillation of the reg- netron but changing the magnetron and pulser units did not remedy the situation. The ultimate source of the oscillation was not determined as a certainty cor- ditions did not warrant the decommissioning of the gear for the time required to conduct a complete inspection and effect repairs. This echo was present from March 22 until the termination of the patrol but its presence in no way affected the realibility or efficiency of the equipment.

All around performance of the SJ Radar was excellent and the addition of the PPI unit infinitely increased the potentiality of this gear as a fire control instrument. The new transmitter-receiver has proven itself to be far superior to its predecessor and has given indications of objects at ranges from 600 to over 200,000 yards. Throughout the entire patrol the radar gave indications of targets at ranges from 600 to 6400 yards which faded in and out with great rapidity although some remained on the screen for as long as ten minutes before being lost. Radar plot raw indications of seconds from six to thirty six knots on some individual targets and after obtaining good course the targets would suddenly disappear. The following plot was made during the night of April 21.

(N) SOUND

Prior to departure Pearl Harbor the port (QC-JK) training motor commenced producing noises which interfere with reception on the JP-1 gear. The frequency range of the noises was from 100 to 6000 cycles and the intensity increased proportionally to the increase in speed of the training motor. The work performed by the base sound ship did not alleviate the condition and after considerable work the majority of noises was eliminated by the ship's force by readjusting the coupling clutch in the shaft between the reduction gear worm drive and the motor shaft. More of the noise was eliminated by reducing the speed of train. This noise was audible on the JP gear with the hand training clutch dis-engaged as well as when it was engaged, but the flaw in the sound isolation mounting could not be found. On March 25 a 250 volt ground was traced to the field coils of the port (QC-JK) training motor, being caused by leakage of the pitometer log packing gland. The coils were removed, washed, and thoroughly baked to eliminate the ground. This did not correct the condition described above.

Sound conditions encountered were from good to excellent, being best in the Ceram Sea, north of BURU and poorest in the Molukka Passage, northwest of Halmahera. Screw noises of a ship in the Convoy of April 15 were heard at 6,400 yards.

The same condition that existed during the first war patrol of this vessel is again developing. The in the port sound had is trained there is a vibrating of the shafting which is transmitted to the hull and which can be heard and felt in the forward compartment. The condition was corrected before by white lead and tallow on the large outer bushing. During the new yard overhaul clearances were taken and the equipment declared to meet specifications.

The JP-1 gear picked up the same screw noises simultaneously at 6400 yards and obtained bearings that check with an accuracy of one degree of those obtained by periscope. The performance of this sonic gear was very gratifying and though nothing could be picked up with own speed in excess of three knots it aided greatly in detecting extraneous noises through out the ship and enabled us to increase the effectiveness of silent running.

(O) DENSITY LAYERS

In the area north west of Halmahera (Lat. 02-37-00N, Long. 127-47-00E) a negative gradient of from 3° to 4° could usually be found between 100 feet and 200 feet. A 3° negative gradient was found at 130 feet on 16 April at Lat. 02-20-00S, Long. 127-20-00E. The sharpest negative gradient of the patrol, 5°, occurred near the western end of Ombai Strait, Lat. 08-33-00S, Long. 124-48-00E, between 80 and 150 feet on 5 May 1944.

(P) HEALTH, FOOD AND HABITABILITY

The health of officers and crew was generally good. There were numerous cases of mild conjunctivitis towards the end of the period spent in the patrol area.

Several men suffered from heat prostration while the ship was in silent running. Recovery was complete and uneventful.

Shortly after reaching the patrol area one man was suspected of acute appendicitis. The treatment used was preventative with the aim of minimizing the possibility of the appendix bursting; or in the event that it did rupture, the result would be an appendicial abscess rather than a general peritonitis. This man was made a strict bed patient. Daily treatment consisted of ice bags to abdomen, frequent administrations of Norphine Tartrate to relieve the pain and control intestinal peristalsis, Sulfathiazole and Sodium Bicarbonate (1 gram) 4 daily doses of each; and a 5% Dextrose saline injections and no food by mouth. Sulfathiazole was not administered after first three days as it brought on vomiting. On the fifth day the ice bags replaced with a hot water bottle and this continued for six days. G.J. C.B.B.C., CPh(A), UMI is coordinated for his quick diagnosis of the symptoms and application of preventative measures. His professional ability is considered to be outstanding.

Food was entirely adequate and well prepared.

(U) REMARKS:

As more submarines are furnished with voice communications gear it is felt that there is need for a standard channel of rapid voice communications for use by boats operating singly that unexpectdly not in an area or bccome involved in the same tactical situation at area boundaries. This channel could serve the purpose of identification and for the forming of an impromptu "Wolf pack". The PADDLE was equipped at Submarine Base, Pearl Harbor, with a "WOYC LL - 310 - Modulated" for use with the TBL and a RBH receiver.

The Dead Reckoning Tracer board installed at Navy Yard, Mare Island, functioned very satisfactorily and is a valuable aid during radar or submerged plotting.

FIRST ENDORSEMENT to
U.S.S. PADDLE Report
of Third War Patrol.

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

Subject: U.S.S. PADDLE (SS263) - Report of Third War Patrol.

1. The Third War Patrol of the U.S.S. PADDLE was conducted while enroute from Pearl Harbor to Fronntable during the period 19 March - 12 May, 1944, a total of 53 days, of which 29 were spent in the assigned areas in Molukka Sea, Coran Sea and Benda Sea. Only two contacts with worthwhile torpedo targets were made. PADDLE successfully attacked the first of these, an enemy convoy, but was unable to gain attack position on the other, an unidentified cruiser or large destroyer. Fourteen torpedoes were fired resulting in five hits.

2. The convoy attacked was made up of one large passenger-freighter, one large tanker, and one small freighter escorted by two Hatsuharu destroyers and two small tanker type escorts. The attack was delivered from periscope depth after a radar and periscope approach to a good firing position. The first salvo of four torpedoes at the AP-AK and A0 resulted in one hit on the A0. PADDLE then fired 4 bow shots at the AP-AK previously missed and 2 shots at a DD. Three hits were observed on the AP-AK and one on the DD before PADDLE was forced down to avoid collision with the A0. Having evaded the inevitable depth charges, PADDLE surfaced 1½ hours after the attack and aggressively maneuvered into position for a submerged attack on the crippled A0 but then decided to eliminate the escorting DD first with a four torpedo spread. Unfortunately, all torpedoes missed, possibly due to running under, and PADDLE was subjected to further depth charging. Further attempts to attack the tanker were discouraged by bombs from enemy planes which had arrived on the scene.

3. It is again noted that the enemy is providing additional escorts for their convoys.

4. The material condition upon return from patrol is considered fair, the major items being the inoperable air conditioning system and the noisy propellor. Defects will be corrected in the normal refit period. In addition, all main engine oil wiper rings will be replaced with new type rings and expanders.

— page 123 —
5. It is believed that the many phantom targets and false contacts were actually birds or floating objects. Further, it is not agreed that the power should be reduced in the transmitt- in order to eliminate these. The reducing of the sensitivity of the receiver can be used as an aid to identify minor lobe echoes, but after positive identification the sensitivity should be returned to its normal operating setting. There can be only one solution to this problem and that is the augmenting of the training program for operators.

6. In general the health of the crew is excellent and the state of morale is high. It is noted that the use of sulphide drugs pulled a patient through after his appendix had burst and the pharmacist nate did a fine job of diagnosis and treatment.

7. The Commander Submarine Squadron Twelve takes pleasure in congratulating this new submarine captain, his officers, and crew for having conducted an aggressive patrol and inflicted damage on the enemy.

(A) PROLOGUE

Entered Fremantle, West Australia on 12 May 1944 after completion of Third War Patrol. Refitted by Relief Crew Number Two of Submarine Division ONE TWENTY ONE and U.S.S. GRIFFIN. Detached two officers and seventeen men and received replacements from Relief Crew of Submarine Division ONE TWENTY TWO. While in dry-dock, took out on wood in port strut bearing to eliminate bearing noise. Increased clearance in port sound head wood bearing to eliminate chattering of sound head.

Commenced post repair period on 26 May 1944. Independent operations and satisfactory sound test held on 27 May. Independent operations day and night 29 May. Starboard shaft developed loud squeal 29 May. Three day training period with U.S.S. CHANTICLEER and H.M.A.S. ADELAIDE as targets 30 May, 1 June, and 2 June. Fired three torpedoes 2 June. Entered dry-dock for removal of starboard shaft squeal on the afternoon of 2 June. Increased strut bearing wood clearance and changed propeller. Out of dock on 3 June and commenced final preparations for departure on patrol. Underway in company with U.S.S. JACK on 4 June. Starboard propeller squealing loudly when clear of channel. Returned to Fremantle and docked in Marine Railway for replacement of "singing" starboard propeller. Departed on patrol in company with U.S.S. JACK on 5 June, 1944, in accordance with Commander Task Force Seventy One Point One Secret Operation Order Number 69-44 of 3 June 1944. Convoy exercise afternoon and night of 5 June with U.S.S. JACK and a convoy consisting of U.S.S. CHANTICLEER, H.M.A.S. DUBBO, and H.M.A.S. HCRSHAN.

Not departed or wiped because previous tests indicate signature to be excellent. Starboard shaft sound-tested satisfactorily before final departure.

(B) NARRATIVE. All times ITEM.

5-7 June 1944

Proceeding via bombing restriction lane in company with U.S.S. JACK, exercising at fire control and plotting drills, day and night approaches, section dives, etc. All operators of the S.J. Radar, most sound operators, and all lookouts benefited from being in company with the JACK. The two radar plotting parties also benefited from the frequent drills. The practice of having two boats proceed together in the bombing lane is considered to have great merit.

0952 Sighted target, which appeared to be a large AK (identification EU). Sighted second "RUPE" type plane. Two CHIDORI torpedo boat escorts in company with target. The target is proceeding northward at 11 knots, less than one mile from the coast. One escort on port quarter close to target, one escort well out on port bow, both echo-ranging. Planes patrolling overhead.

1000 Escort on bow seems to suspect our presence and has headed toward, shifting to short scale on echo-ranging. Running at 120 feet and closing track at high speed between observations. Close escort passed ahead and then proceeded toward the target. Target followed coast-line closely and PADDLE lost in bearing and range.

1023 Unable to close target to torpedo run less than 4,800 yards with large track. Broke off attack and swung around to southward. Did not fire because torpedo run was at the limit of Mark 23 torpedo and the torpedoes would surely be seen in flat calm sea prevailing before ever reaching target even if range estimate was in error.

1025 Believe we were sighted by plane at this time, for close escort turned back and headed toward. Made echo-ranging search, passed close aboard on port side, and then withdrew in direction of target. Evaded at deep depth. No gradient.

0942 Twelve minutes after diving, received a very large bomb or depth bomb close ahead and above. PADDLE was at 150 feet and swinging right. Explosion did not sound like a depth charge but shook the ship considerably and did minor breakage damage. All gyro spindles of forward tube nest, which were engaged at the time, were bent back by movement of torpedoes in tubes to the extent that the spindles had to be disengaged by force and then replaced with spares.
1145 Returned to periscope depth and found bomber circling at close range. Now eight miles from scene of attack. Sea flat calm. Went deep again after noting that small air bubbles were escaping from after part of ship, probably from safety tank vent as safety tank had a bubble in it after going deep.

While swinging right and watching, second destroyer bearing down on port beam with 20" starboard angle on bow, preparing for stern tube shots, one torpedo explosion was heard followed 3 seconds later by a second torpedo explosion. Huge cloud of smoke enveloped first destroyer, completely obscuring it. First AK seen to have turned parallel to torpedo wakes. Believe destroyer warned AK of approaching torpedoes but that the first explosion was third or fourth torpedo hitting AK and the second explosion was a hit by first of two fired at destroyer. 8 second interval used between all torpedoes. Sighted cloud of dark smoke near hull of AK, but she showed no other evidence of being hit. As smoke cleared away from first destroyer, she was seen to be sinking by the bow, stern well out of water and deck going under aft of bridge. Identification as to type is certain; as to class of destroyer it is indefinite. It was either HUTSUKI, MINEKAZE, or WAKATAKE Class.

Stern tubes were ready but second destroyer had maneuvered to position on port beam and was closing with a zero angle on the bow, range less than 1,200 yards. Second AK not within range. Tent deep and commenced taking a total of 24 depth charges from echo-ranging destroyer and unidentified listening escort. Both passed overhead several times, but depth charges were dropped sparingly, 2, 3, or 4 at a time, none close enough to do damage. Evaded on generally north west courses into rain at 280 feet under an 8% negative gradient, running at 2/3 speed, 80 R.P.M.

Destroyer searched with echo-ranging in close vicinity until noon, and then faded out to the southeast.

Distant single depth charge at 1149. Unidentified escort believed to be searching to northeast, periodic echo-ranging from that direction. Periscope depth at 1317. Nothing in sight. Visibility poor due to general light rainfall. Changed course to south. Made reload forward and checked torpedoes aft.

0022 First contact by SJ on one of several ships already in sight. Range 17,900 yards, target course 220°T, speed 9½ knots.

0037 A total of ten small ships are now in sight. Radar can pick up only four or five. Convoy course now 165°T. The convoy is probably composed of six small or medium AK's (UN) and four escorts. Both targets and escorts are relatively small contacts, and their small size make it difficult to determine which are targets and which are escorts.

0107 Central and largest ship of convoy fired two red rockets. A faint flashing white light was also seen on this ship. Closest range at this time, 14,000 yards.

and gained position on line between last known convoy
position and MAKASSAR STRAIT. Believe convoy would
head in this direction after losing contact with us.

TARGET DATA - DAMAGE INFLICTED

Description: Two large Japanese AK's (EU) in line ahead formation, distance about 2,500 yards with two destroyers of either the HUTSUKI, MINENKAIZ, or WAKATAKE class as escorts. Destroyers deployed about 1000 yards to starboard of AK's track, the leading destroyer slightly forward of beam of leading AK, other destroyer about 2,500 yards behind first destroyer and on a track about 500 yards to the westward of that of the leading destroyer. On the starboard quarter of the second destroyer was a third escort, a smaller, unidentified type.

Ships sunk: Destroyer of MUTSUKI, MINENKAIZ, or WAKATAKE class.

Ships damaged: Large AK (EU).

Damage determined by:
1(a) Torpedo explosion at time of run for third or fourth torpedo fired. Cloud of dark smoke seen near hull of AK. Firing interval between all torpedoes fired was 8 seconds, but two explosions heard were 3 seconds apart.

1(b) Destroyer enveloped in large cloud of smoke at time of explosions. Sound reported that loud screws of destroyer stopped immediately. As smoke cleared, bow of destroyer was seen to be under as far aft as the bridge, and the stern was out of the water.

ATTACK NO. 1(a)

Target draft: 15 feet. Course: 142°T. Speed: 11 knots. Range: 2200 yds.

Remarks:
Target sighted torpedo wakes and paralleled to evade. Fired gun one minute after firing torpedoes and a dull explosion was heard at this time. Not believed to have been a hit however. Large amount of blue smoke from torpedoes seen in periscope.

(I) MINES

No mines or indications of minefields were noted.

(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS

No new evasive tactics were employed. Usually evaded at 80 R.P.M. beneath a negative gradient keeping escorts astern.

The patrol boat encountered off DAVAO GULF on 21 June evidently had 10 cm. radar by the interference noted. Although we were tracking the patrol boat, there was no indication that he had detected us.

On 9 July the small escort for the medium AK was discovered to be using echo-ranging at 14 kcs.

The convoy contacted early on 10 July definitely had radar (which we could not detect) or some type of DF equipment.

(K) MAJOR DEFECTS AND DAMAGE

ENGINEERING (MACHINERY)

Following main engine head bolts broke:

8 June
#1 M.E., #1 Unit, upper left.
10 June
#2 M.E., #3 Unit, upper left and upper right.
28 June
#3 M.E., #9 Unit, upper left and upper right.
20 July
#2 M.E., #3 Unit, upper left.

10 June
After making fresh water, started ro-distilling for battery water. Distillate showed violent reaction to silver nitrate; Kleinschmidt water tester reading 60-80 points. After distilling from sea water nearly continuously for 4 days, distillate finally became satisfactory for battery water use. Possibly due to chlorination of #1 fresh water tank during refit.

12 June
120 Volt battery ground, both batteries. Removed and washed out battery ventilation ducts. Probable cause: skimpy paraffin job.

13 June
#4 main engine, #13 unit: noted fresh water from cylinder test cock. Inspection of liner showed 8"x2" section caved in. Probable cause: Noticeable scaling in fresh water ferrules had restricted circulation, allowing local overheating and failure. Renewed liner and rings.

21 June
#3 main motor after bearing rose to 195°. Braked shaft, removed bearing. Inspection revealed incomplete machining of bearing metal from oil retainer ring grooves after rebbabbitting. Bearing undamaged. Cleaned up and reinstalled.

6 July
#5 main engine, #13 unit: fresh water leaking from head. Removed head. Gasket has been installed off-center, allowing hot gasses to leak by and burn water-sealing ferrule grommets.

16 June
Gyro compasses: Master and auxiliary gyros have been a constant source of trouble. Noisy running, followed by loss of vacuum, pointed to bearing troubles. Badly flatted bearings in both rotors of both gyros were renewed several times, using last bearings available spares allowance inadequate for necessary complete job on all rotors. Complete rotor disassemblies and cleanings, frequent vacation, constant attention, and use of home-made spares fashioned from rubber gloves, main engine water ferrule grommets, rubber cement, and belladona, resulted in both gyros being restored to usable, if not reliable, condition.

BUCK, Howard Lee, CEM(Ax), U.S. Navy, deserves much credit for his perseverance, ingenuity, and workmanship.

20 June
Renewed flat bearings, #1 I.C. motor generator.

26 June
Auxiliary gyro oscillator motor burned out; replaced with spare.

(L) RADIO
No major casualties were experienced in radio material during this patrol. As on previous operations, the antenna trunk showed signs of leaking but no further increase in ground readings was shown after inspection plates were tightened.

Reception of VXIO while in the CELEBES SEA area was never good. 9250 kcs. was the only readable frequency at night; 4370 was occasionally good at sunset and sunrise; 12630 was first received on 24 July at 0500Z in position 14°-00'S, 120°-49'E, 1,110 miles from PERRE. Signal strength was usually 2 or 3 with poor readability while jamming stations always had considerable power.

(L) RADIO (Cont'd.)

Because of enemy deception, transmission was made after several call ups to VHKO with receipt considered definite only after rebroadcast of the message on the bakers. PADDLE message #4 was cleared to what was probably a Jap impersonator of VHC with transmission without receipt being secured due to the late hour (0530) and the desire to avoid almost certain D-Fing. There were at this time three stations claiming to be VHC and numerous other Australian stations were well represented on the frequency (8470), in addition to strong jamming from an avowed Jap station using Kana code. It was noted that at all times VIXO answered on the calling frequency rather than the bakers as prescribed.

The coordinated & tack frequency was queried at all times while in the patrol area but no use was made of it. Boats in other areas were heard on several occasions very strongly. While in the DAVAO GULF area, supposed small surface craft using cells Ray, Eddie and Morrocco were frequently heard.

As both medium frequency receivers were constantly in use, all press news was received via VIXO. At the start of the patrol this service was brief, sent at excessive speeds, and not repeated; some nights none at all was sent. It is suggested that this press could be repeated during the long silent periods, usually in the morning. These present two or three hour blank periods at this time are disturbing, as the operator cannot be sure that he has not missed a message until transmission starts again and he is compelled to tune the receiver constantly in the interim. It is also recommended that the quantity of press news be increased.

Boats operating in the exercise area off Premantle were heard distinctly while in the SANDO SEA on 2785 kcs.

VHF radio, installed experimentally during the training period was tested unsatisfactory with U.S.S. JACK. Maximum range was 9,000 yards on the A band with readability very poor. No reception was obtained on the B, C, or D bands. The lack of proper antenna is undoubtedly the cause for poor performance. The following antennae were tried: (1) SD whips both with and without bazooka designed to match the output impedance of VHF with the input impedance of the SD mast; (2) Ship's wing antennae. Best results were obtained with the SD whips without the bazooka. A possible solution might be

Subject:  (L) RADIO (Cont'd.)

The operation of the SJ-1 radar was satisfactory during this patrol. Technical difficulties were few and of a relatively minor nature, consisting chiefly of tube failures and an open resistor (R-741) in the range unit. The 721-A tube in the duplexer cavity was changed on an average of 175 operational hours, and screen sensitivity was good for the entire patrol. Difficulty was encountered with the voltage regulator tubes (991)(LP-1, 2, 3, 4) in the receiver unit and three complete sets were used. The 200% spare allowance of this item is the bare minimum. The time delay relay motor was unsatisfactory in its operation, sticking several times during the patrol. A small toggle switch was installed, by-passing switch (S-1) for emergency use.

Before leaving on patrol, the transmitter unit was changed since all efforts to eliminate the phantom target in the previous transmitter were fruitless. On 8 June, five days after the change was made, another phantom pip appeared at 1370 yards on all bearings. This phantom was finally eliminated by the elimination of the standing wave on the wave guide. The cavity and tuning stubs had been adjusted for maximum echo, but the reduction of the standing wave also seemed to increase the sensitivity of the set.

Some difficulty was again experienced with minor lobes on this patrol. On 4 July the small ship contacts were lost in the minor lobes of SANGI ISLAND.

In several cases, on moonlight nights with good visibility, ship contacts were made from the bridge before the radar could pick them up. Maximum ranges were: (1) 16,200 yards tracking another sub. during the run to the area; (2) 13,700 yards on a small patrol boat; (3) 21,000 yards on a ship contact; (4) 150,000 yards, estimated, on secondary land contacts. Minimum range was 980 yards on a small sailboat.

U.S.S. PADDLE (SS263) - Report of Fourth War Patrol.

The desirability of a reliable signalling system utilising the SJ Radar should be given consideration. If the character of radar interference could be established as friendly immediately, by a prearranged system, the usual long process of trying to get the other ships attention for receiving could be expedited.

Such a system or identification is both feasible and possible and could be simple in its operation.

Many cases of radar interference were encountered as follows. Magnetron Type 706 AY, serial 017775 was used for the entire patrol.

9 June Received standard radar interference from a U.S. Submarine up to an estimated range of 35 miles.

13 June Received standard radar interference of a type similar to our own. Suspected to be from a U.S. Submarine known to be nearby. Major lobe 100 wide. Minor lobes 30 wide. Could synchronize with the pulse. Sweep frequency varying from 5 to 10 per minute.

14 June 0430 In position 05-56-008, 127-38-45E, radar interference, very weak, 304° to 317°T. No minor lobes apparent. General indication of sweeping but strength of interference too weak to give definite information.

0515 Experienced interference again at about 021°T. Very brief but thought to be like the 0430 contact. Since a plane was sighted shortly after, the interference could have been from it, as it could not be positively identified as our own due to weakness of signal and the short time it appeared on the screen.

15 June 1513 In position 03-23-008, 125-18-15E, radar interference unlike our own, bearing 196°T. Pulse frequency similar to P.R.F. used in SJ. Narrow band of about 10 on PPI and apparently highly directional, as SJ had to be trained directly on bearing. Pulse duration about 1 second. Pulse width slightly wider than SJ. Appeared to be keyed at 2 to 3 minute intervals. No minor lobes detected. Decided most probable source of interference was a shore station located on POINT PALPETO, northwest end of BORROE ISLAND.

— page 168 —
19 June 2343. In position 05-43-30H, 126-20-45E, radar interference bearing 2680T. Similar to our own in every respect. Same P.R.F. and sweep frequency. Weak signal. Drow aft in bearing and was lost at 2325.

20 June 0504. In position 06-18-30N, 126-23-45E, picked up radar interference from direction of small patrol boat. Very strong and laced solidly across whole screen. Wide pulse of 1 or 2 seconds duration. This was of fairly brief endurance. Continued to receive standard radar interference from direction of target; similar to our own in every respect. Sweep frequency 8 to 30 seconds. P.R.F. and pulse width similar to SJ. Minor lobes appeared from target at 7,000 yards. Lost all interference at 10,000 yards.

Large rain squalls were apparent from the bridge and the unusual indication first received may have been due to reflection from these rain squalls.

23 June 2108. In position 06-08-30N, 126-01-45E, radar interference bearing 2000T. We could synchronize with the P.R.F., and the pulse width and sweep frequency were like the SJ. Decided it to be friendly in character.

24 June 2018. In position 05-13-00N, 126-12-15E, experienced similar interference as on 23 June. True bearing changed from 2660 at 2018 to 2860 at 0230 on 25 June. Definitely like our own SJ. Interference was intermittent and weak most of the time. Occasionally it appeared strong and at the same time the pulse width increased. On each of these occasions a careful check from the bridge showed a rain cloud on the bearing of the interference, bearing out the previous deduction that the straight transmission was being reinforced by reflections from the rain squalls.

25 June 2005. In position 05-57-00N, 125-58-00E, radar interference similar to previous day, 2250T. Interference continued throughout night.

26 June 0318 In position 06-21-30N, 126-14-30E, contact was made at 14,800 yards and target very likely was one of our own submarines

2010 In position 05-15-45N, 126-03-30E, similar radar interference to previous nights bearing 290°T.

27 June 2000 In position 06-34-00N, 126-00-45E, above interference continued throughout night. Lost contact on bearing 173°T at 2355.

11 July 0154 In position 02-45-45N, 124-13-15E, evidence of another radar bearing 149°T. Could synchronize with the pip. Pulse width and sweep frequency similar to SJ. No minor lobes at this range. Major lobe about 5° wide.

0240 In position 02-50-00N, 124-19-15E, detected attempts at signalling on the PPI. From 0240 to 0318 exchanged signals with source of interference using wave guide flapper. Were able to get coherent messages and to identify target. Method is slow and the two parabolas must be trained direct. y into each other for good results. In effective identification code for use with the radar would be very helpful in determining quickly and surely the character of interference on the SJ.

19 July 2047 In position 00-41-15S, 126-27-30E, radar interference bearing 170°T. Weak and intermittent but apparently similar to the SJ.

2054 Synchronized with the P.R.F. Pulse width the same as SJ. Sweep frequency about 10. Interference stronger and narrow minor lobes apparent. Main lobe about 7° wide. Bearing drawing aft.

2130 In position 00-57-30S, 126-30-15E, interference appeared to be irregular and signalling was suspected. No coherent words could be distinguished, however, and it may have been the result of sweeping combined with a fairly long range.

2240 In position 01-12-15S, 126-37-15E, lost contact bearing 319°T.

(N) SOUND (Cont'd.)

before the attack and afterward just prior to each dropping of depth charges.

Echo-ranges were attempted on three occasions with no results. This may have been due to a negative gradient which was prevalent in the area, giving good protection to PADDLE from surface echo-ranging. This failure may have been caused by improper tuning of driver to QC head.

The continuous high whine of the super-sonic sound motor generators is detrimental to the efficiency of the JP-1 sound gear, but no solution of this problem can be offered by the ship.

(O) DENSITY LAYERS

In the area of CAPE SAN AGUSTIN on HMID N/0, a negative gradient of from 2° to 4° could usually be found between 100 feet and 200 feet. In the vicinity immediately westward of the SANGI ISLANDS, a negative gradient of from 2° to 5° could usually be found between 100 and 200 feet. A 6° negative gradient was found between 80 feet and 200 feet 10 miles north of Northwest CELEBES or longitude 121° east at 0555 on 9 July. A convenient 8° negative gradient was found four miles southwest of SANGI ISLAND down to 280 feet at 0910 on 6 July. There are few localities in the South CELEBES SEA where a negative gradient is not found before reaching 300 feet.

(P) HEALTH, FOOD AND HABITABILITY

The health of officers and crew was generally very good.

One man fell down a hatch on 30 Juno 1944 and received treatment as a bed patient thereafter for a possible fracture of the left patella (knee-cap). Treatment consisted of elevation of the afflicted part and the application of continuous ice packs to knee until all swelling had gone down. The knee was strapped firmly with adhesive tape to provide a close approximation of the fragments.

Air conditioning kept the humidity down as designed. The temperature inside the boat usually was the same as that of the surrounding waters.

Food was entirely adequate and well prepared.

Performance, care and upkeep of Mark 18 torpedoes with recommendations and comments.

No remarks as to performance can be made as none were fired.

Four torpedoes were carried in the racks aft. Upon receipt of the torpedoes on board, each was carefully checked for grounds, continuity of hydrogen eliminator circuit, and low cells. Each torpedo was loaded into a tube, all spindles engaged and tested, and the torpedoes withdrawn and stowed in the racks. All torpedoes were in an excellent condition when received.

Torpedoes were charged every six or seven days. In this time the usual drop in specific gravity was twenty-five points. This quick drop was enhanced by the warm temperature in the boat in the patrol area. Battery charges were secured using the constant voltage method. It was found that almost one ampore hour was required to raise the specific gravity one point.

After being on patrol for 32 days and having put in five charges, it was necessary to water the batteries. No means was provided for measuring the height of electrolyte, so the following method was devised:

Having noted when the torpedoes were received that removing a hydrometer full of electrolyte left the cells filled just to the top of the plates, a hydrometer with the float removed was inserted into each cell and the electrolyte removed. This indicated the amount of water necessary to bring the height to its original level.

The only grounds detected, appeared after watering the batteries and were quickly cleared up by washing the cell tops with a soda solution.

It is recommended that: A flexible stick be provided for measuring the height of electrolyte; and the auxiliary charging lead be provided with an individual ammeter and rheostat.

FIRST ENDORSEMENT to
U.S.S. PADDLE (SS263)
Report of Fourth War Patrol.

From: The Commander Submarine Squadron TWELVE.

Subject: U.S.S. PADDLE (SS263) - Report of Fourth War Patrol - comments on.

1. The fourth war patrol of PADDLE occupied a period of 54 days and was spent in the CELEBES SEA and Eastern Approaches to DAVAO GULF.

2. Area coverage was good and PADDLE made contact with four enemy groups meriting torpedo attacks.

3. The first of these contacts was a large freighter inbound to DAVAO escorted by two CHIDORI torpedo boats and having airplane coverage. PADDLE was unable to close the range to less than 4800 yards and the ship proceeded northward less than one mile from the SAN AGUSTIN peninsula.

4. The second contact was the result of a persistent search and PADDLE was able to get a hit in a destroyer which is believed to have sunk and a hit in a freighter in a multiple daylight periscope attack. The activities of another destroyer, a remaining escort and a plane kept PADDLE submerged the remainder of the day.

5. Three days later PADDLE found an eastbound escorted freighter close aboard KANDI point on Northwest CELEBES but maneuvers of the target forced PADDLE into a daylight attack with a range of 2200 yards with track angles of 146° - 148°. Target observed the wakes and successfully maneuvered to avoid.

6. The next and last contact was at night with an escorted convoy which checked during initial hour of tracking on courses 220° and 165°. Convoy detected PADDLE when least known range was 14,000 yards; the central and largest ship firing two red rockets. On subsequent attempts of PADDLE to "end around" the convoy changed course away 20° each time PADDLE got aboard, finally ending up on course 045°. PADDLE withdrew from radar contact as daylight approached and then re-established

0812 In position 11°06'5", Long. 122°20'5", sighted MAVIS type plane headed toward, distant 6 miles. Went deep. (Aircraft Contact: F1).

0945 Returned to periscope depth. Nothing in sight.

1945 Surfaced. Underway for OMBAI STRAIT.

30 August 1944

0510 In position Lat. 08°57'5", Long. 123°35'5", dived. Established periscope patrol.

1941 Surfaced for transit of CBAI STRAIT. The new VHF antenna has leaked various amounts on each dive since its installation. Unable to find source of leak, but believe insulator to be porous.

31 August 1944

0100 SJ Radar has indications of similar radar approximate vicinity of BODA POINT, PANTER ISLAND, position Lat. 08°35'5", Long. 124°05'5". Not believed to be friendly. Possibly ship-borne. Discontinued searching by SJ in this sector.

0257 In position Lat. 08°24'5", Long. 125°13'5", short contact on APR on 305 megacycles. Appeared to be sweeping every two minutes.

0300 Transited narrows of OMBAI STRAIT without surface contact.

0310 Intermittent contact on APR on 305 megacycles, same as above. Believed to be from a night flying plane.

0601 Submerged north of entrance to OMBAI STRAIT. Conducted periscope patrol because of close proximity to land and enemy radar indications during passage of STRAIT.

1921 Surfaced, heading for northwest end of BORRO ISLAND.

1 September 1944

Underway on surface. No contacts throughout day.

2247 Received change of area assignment to SULU SEA, south of Lat. 90°30'N.

2 September 1944

0030 Passed LIFOMATOLA ISLAND abeam to port, distant 15 miles on course 020°T.

0742 In position Lat. 00°55'S, Long. 125°44'E, surface periscope watch sighted a small torpedo boat escort bearing 014°T, coming out of a rain squall, distant about 15,000 yards. (Ship Contact #1). Dived after noting that patrol boat was definitely alone. Torked around to westward as patrol boat held course 150°T, echo-ranging on long scale. Not large enough for torpedo attack.

0945 Lost all contact on patrol boat.

1350 Surfaced, heading for BANKA PASS.

1518 In position Lat. 00°26'S, Long. 125°37'E, SD contact at 16 miles, closing. Dived. (Aircraft Contact #2).

-1715 Surfaced.

2117 Received further instructions regarding change of area but held off action. Ledgement because of AP contact and transit of BANKA PASSAGE in bright moonlight.

2131 In position Lat. 00°28'N, Long. 125°44'E, AP picked up radar contact on 152 megacycles. Believed to have been ship borne. Contact faded at 0100 in position Lat. 01°31'N, Long. 125°47'E.

3 September 1944

0332 Transited BANKA PASSAGE.

1134 In position Lat. 02°50'N, Long. 123°31'E, SD radar contact at 10 miles, closing. Dived. (Aircraft Contact #3).

1343 Surfaced, but two minutes later sighted unidentified.

— page 183 —
1343 aircraft bearing 1830T, distant 8 miles, dived. (Cont'd.) (Aircraft Contact #4).

1930 Surfaced, heading for SIBUTU PASSAGE. Found the porcelain insulator at the top of VHF antenna broken and the whole assembly bent. Pulled cable and blanked off pipe. Will construct a portable antenna requiring lead through conning tower hatch.

2040 Transmitted message acknowledging receipt of change in area assignment and further instructions.

4 September 1944

1117 Within fifty miles of SIBUTU PASSAGE, dived. Conducted periscope patrol, killing time for passage tonight.

1938 Surfaced, proceeding toward SIBUTU PASSAGE.

2153 Commenced transit of SIBUTU PASSAGE favoring SIBUTU ISL.ND side. Very bright moonlight.

2330 In position Lat. 05001'N, Long. 119031'E, sighted small craft bearing 0670T, distant about 12,000 yards, on an opposite course making 25 or 30 knots. Whatever it was, PADDLE apparently was not sighted.

5 September 1944

0215 Passed between PEARL BANK REEF and DOC C.N. ISL.ND.

0300 Transmitted second acknowledgment of receipt of change to patrol orders. One and one-half hours of transmitting required.

0619 In position Lat. 06261'N, Long. 119051'E, dived. Decided to conduct periscope patrol off entrance to PANGUT.R.N PASSAGE because of length of radio transmissions, and close proximity to TAU TAU.

Had various pieces of floating debris in sight during morning, but at 1433 picked up possible single stick mast with bulbous top characteristic of some

— page 184 —
5 September 1944 (Cont'd.)
torpedo boat escorts in this area. Bearing 172°T, distant 14,000 yards.

1429 Mast disappeared from sight. Searched at 55 feet but could not regain contacts, so at

1505 Surfaced and searched to south and southeast with-out success. Mast was probably a floating coconut tree.

2144 to 2239 Made false approach on the S.NGBOY ISLANDS which looked very much like a large Maru and escort in bright moonlight at range of 60,000 yards.

2255 Converted F.B.T. to a main ballast tank.

6 September 1944

0500 Made a series of four dives to flush out 4 main ballast tank.

0600 Divod ten miles off SUBUCO BAY. Visibility in bright moonlight prevents closing coast to less range for diving position. Closed to patrol three miles off bay entrance.

1225 Sighted small single engine float type plane bearing 160°T, close and heading toward. Believe our presence was suspected, but no bombs dropped. Went deep. (Aircraft Contact #5).

1414 At periscope depth. No plane in sight. This was our first contact with what seems to be a routine air patrol close to west coast of MIND.N.O at points suitable for submarine attack on ships hugging the coast. Air patrol is maintained whether or not convoys are coming through and the PADDLE was apparently sighted with a regularity that was disturbing, to say the least. Light gray camouflage and paint pecling off water-line is most probable cause of sighting in the calm, clear water of this area.

1635 Sighted small motor-powered fishing boat bearing 206°T, distant 9,000 yards, on northerly heading. Observed and evaded.

— page 185 —
1817 Lost sight of fishing boat on bearing 030°T.
: 1941 Surfaced. Underway on surface patrolling off coast and headed for SINDANG POINT.
: 2054 In position Lat. 07°35'N, Long. 121°50'E, SJ Radar contact bearing 003°T, range 5,300 yards. Commenced tracking.
: 2100 Target is a small slow-moving craft, believed to be this afternoon's fishing boat.
: 2153 The lubricating oil pump drive shaft on number one main engine again sheared, necessitating that the engine be placed out of commission. This was the third occurrence of this casualty on this patrol. Out of commission 40 hours.

7. For additional information:
   - For position on miles north of SIND NGAN POINT, divd. Established periscope patrol closing point.
   - For smoke bearing 242°T. Started closing western side of SIND NGAN POINT.
   - For unidentified float type monoplane in vicinity of smoke. (Alteraf Contact #6).
   - For mast and stacks of three large ships. (Ship Contact #2).
   - For sighting in sight: One medium tanker, two medium AK's, two small AK's, two torpedo boat or DE type escorts, and one small coastal tanker type craft unusually broad and squat with very high stick masts. Thero may have been another escort well astern. The tanker was leading the medium AK's and very close to the coast. Wall pass about 500 yards off tip of Point. One escort on port bow and one on beam of large ship column; both patrolling on station. Two small AK's brought up the roar. Unusual engine aft craft (possible Q ship) well outboard on beam of entire formation. Two planes overhead. Below is a picture of disposition at time of firing. When seen bows on,

7 September 1944 (Cont'd.)
The escorts looked like destroyers, but had lines of our DE's whom scum from the beam. Wooden hull indicated shallow draft. The tanker was a medium sized modern vessel with relatively low stack. She was probably loaded to half capacity. The AK's were medium sized, now looking ships with two single stick masts, one fairly low stack. No unusual features. No identification as to name is attempted because all periscope observations were very brief with flat calm sea prevailing. The AK's wore not heavily loaded.

The approach was made on the tanker since it was the most valuable ship of the convoy. Ran at 100 or 150 feet between early observations. Only the leading escort echo-ranged prior to and after attack. He crossed ahead shortly before firing, distant not more than 300 yards. Formation speed 9.5 knots. The large ships hugged the coast closely and changed course accordingly during the approach.

1651
Fired four bow tubes at A0. Depth setting 6 feet, torpedo run 1875 yards, 348° average gyro angle, 106°P av. rage track angle, 3 degree spread between torpedoes. Continuous bearings during firing. Immediately shifted set-up to leading AK and fired two tubes set at 4 feet, 21° right gyro, 73° port track, torpedo run 1350 yards, 2 degree spread. All torpedoes heard to run toward targets. Three seconds after firing last torpedo at AK, the first hit (1/2) was observed in A0. A second hit (1/4) in A0 was heard 14 seconds later while periscope was on near escort on port bow. Two timed hits in AK wore heard (59 seconds after firing) while periscope was on escort on starboard beam, distant less than 1200 yards. Two torpedo wakes were seen headed for AK as periscope was swung around to DE. Escort on starboard beam seen to have directly turned toward, so the order was "run to go deep. Periscope went under (had beam running at 65 feet because of flat calm sea) before extent of damage to AK and A0 could be seen. Loud, characteristic, breaking up noises wore heard almost immediately however, and continued for some time after depth charging began. It is believed that of those two ships at least the AK sank and possibly both did.

— page 188 —
1655
Commenced taking a total of 45 assorted depth charges and bombs; none close enough to do major damage, but all jarring the boat considerably. Rudder ram noise of last patrol returned immediately after first string of close depth charges. -

Two escorts passed overhead several times dropping patterns of 6 to 8 charges. Evaded on northwest-early courses at 300 feet, 80 R.P.M., under a convenient 7 degree negative gradient existing at 200 feet. However, it was almost an hour before both escorts could be kept astern, and 43 depth charge at 1733 was quite close. One escort echo-ranged throughout while the other seemed to conduct a sonic search on opposite side. Both escorts stayed fairly close aboard until about 1300, but did not drop after 1733. It is believed that their depth charge supply was exhausted during their early close runs.

1844
Commenced return to periscope depth.

1912
At 75 feet, heard two aerial bombs seemingly pretty well astern.

1913
Small dark shape in direction of echo-ranging. Nothing else in sight.

1945
Surfaced. Opened out to north of SINDANGAN POINT for reload forward.

2026
Commenced return to scene of attack to look for cripples. All main engine still out of commission, charging on one main generator and the auxiliar.

2112
In position about 4 miles north of SINDANGAN POINT, have two small radar contacts on SJ, one at 3,800 yards, bearing 2250T, which is echo-ranging and conducting a search near scene of attack. Second contact at 11,450 yards, bearing 1600T, which is stationary. First contact, assumed to be echo-ranging torpedo boat escort, is in poor position to cover contact 2 if that is a cripple. Contact 2 is 5 miles away and around the northern tip of SINDANGAN POINT from the echo-ranging escort. Contact 2 is not a large ship contact on the SJ and was first picked up faintly at 9,600 yards.

— page 189 —
2112 (Cont'd.)
Believed to be an escort vessel lying to and conducting sonic search. In view of developments next morning, it is now thought that this was the possible 3 ship. No other SJ contacts could be made near the point on either side, so decided to search along coast for remainder of convoy enroute to CEBU.

8 September 1944

0200 In position 9 miles, bearing 1250T, from APO ISLAND at entrance to BOHOL STRAIT, should have overtaken remainder of convoy by this time, and now have just enough time to return to SINDANGAN POINT before sunrise. Commenced return, searching farther out from coast than earlier in evening.

0515 In position ten miles north of SINDANGAN POINT, sighted patrol boat bearing 1600T, distant about 10,000 yards on an easterly course. Patrolling at slow speed and echo-ranging. SJ had contact at 0524 at 9,520 yards. Turned to give small silhouette and slowed while tracking.

0531 Sighted second small ship bearing 2000T, on a north-easterly course, first radar range 5,420 yards. Came right, putting one contact on each quarter and commenced opening range, but at 0541 second, non-echo ranging contact, fired two red rockets, signalled to escort, commenced firing deck gun at PADDLE, and turned toward, closing range to 4,700 yards before we began hauling out at full on three main generators on course 3400T. Escort turned on searchlight periodically but did not sweep. He gradually closed firing ship which had low, unusually broad silhouette. Both ships look too small for torpedo attack. All splashes seen were well astern.

Range opened slowly but firing ship turned to stay on our track until 0558 when PADDLE changed course to 3000T, (had been sucessively on 3400T, 0200T, and 0000T) and then gave a 300 port angle on the bow. Range 5,200 yards. Thought we had been lost to sight, but at 0601, firing ship sent up 3 red rockets and again turned toward. Sunrise will be at 0640.

— page 190 —
0605
Dived. Changed course to 260°T and commenced getting off track at 2/3 speed.

: 0619
Ship that had been firing now identified in periscope as the broad, squat, coastal tanker type, with two unusually high stick masts, that was to seaward of the convoy formation yesterday afternoon. The torpedo boat is now astern of him and both are headed for PADDLE with small port angle on the bow. It is believed that these two were the radar contacts off SINDANGAN POINT last night and that the low, broad, shallow draft craft is a possible ship, or converted escort.

: 0633
Both ships have slowed and are now echo-ranging, short scale; steady true bearing on ship.

: 0700
Q ship passed close aboard astern. Escort searching on port quarter. Echo-ranging ceased. Both ships seemed to be tracking. PADDLE with fair success, but no depth charges were dropped.

: 0725
Commenced return to periscope depth intending to use 1k. 18 torpedoes with zero depth settings.

: 0740
Q ship lcst to sound. Escort now echo-ranging on bearing 000°T.

: 0745
At periscope depth. Sighted float type monoplane (Aircraft Contact 7), bearing 200°T, distant about 8 miles. Torpedo boat escort bears 079°T, distant about 7,000 yards, angle on bow zero. Q ship over toward land bearing 120°T, hull down at periscope depth, 65 feet. Came right to 350°T and commenced getting off escort track at 150 feet, 2/3 speed. Escort closed on steady bearing until 0820, when PADDLE changed course to 235°T and escort suddenly drew off to the north after making short scale echo-ranging search on starboard beam. He had contact, return echoes could be heard, but no depth charges were dropped.

8 September 1944 (Cont'd.)

0830 At periscope depth. Escort bearing 000°T, angle on bow 180°, range about 7,000 yards. Nothing else in sight. It is not known why he should so abruptly leave an apparently good contact and head off all by himself. Did not see him or the ship again.

Continued periscope patrol on course 270°T, expecting escort to return or ship to stand out from Point. Now 12 miles bearing 323°T from SINDANGAN POINT.

Float type monoplane searching near scene of attack was periodicaly in sight all morning.

1025 Commenced closing SINDANGAN POINT on course 180°T.

1154 Changed course to 135°T. Experienced northerly set during day and surfaced at 1954, 5½ miles, 353°T from SINDANGAN POINT.

Patrolled to northward in direction escort had taken when last seen. No further contact made.

9 September 1944

0545 In position Lat. 08°53'N, Long. 122°52'E, dived. Closing SIATON POINT, NEGROS. Had several small railtouts in sight during day.

0542 In position Lat. 07°24'N, Long. 121°50'E, dived. Established periscope patrol closing SIBUCO BAY.

0926 Very close depth bomb explosion, shaking the boat considerably. T'ud been four minutes since the last periscope could see which time nothing was in sight. Went deep. (aircraft contact #9).

0928 Second close depth bomb.

0940 Third close depth bomb.

0944 Fourth depth bomb. This fourth depth bomb was heard to hit the water, or arm, on the sound gear, as had

0944 (Cont'd.)
The other three. Soon after this noise, something metallic loudly hit the hull of the PADDL3 aft of conning tower. The metallic hitting noise was followed by a small muffled explosion, as if from a great distance, but water was heard moving through the superstructure directly thereafter. It is believed that the fou. the geith bomb hit the PADDL3 and very fortunately failed to function properly.

Cleared area on north-westerly courses running at 250 feet at 30 R.P.M. No screws ever heard on sound gear. Conditions excellent.

1724 Heard distant bomb or depth charge explosion.

1812 At periscope depth. Nothing in sight.

1943 Surfaced. Commenced surface patrol on traffic lane from BASILA STRAIT to INDORO STRAIT.

11 September 1944

0546 In position Lat. 03°00'W, Long. 121°52'E, dived. Established periscope patrol.

1335 In position Lat. 07°52'W, Long. 121°40'E, sighted ship bearing 1530T, distance 1,000 yards, coming out of rain squall. Commenced periscope patrol. (Ship Contact 3).

1351 Target is a hospital ship.

1359 Hospital ship is marked as prescribed. Has the lines of the KATAURA BAY but is much smaller than 17,000 tons. Fire control part in coming tower all had a look. Took 1.5 hours of fire.

1955 Surfaced. Commenced after 1.5. Subastar. Closing land to 8,000 yards. Three more close. Search of coastline northward ended 24 hours from SISUCC BAY to MADALAY PORT.

TARGET DATA - DATA AGE I.F.I.CITE

Description:
One medium Japanese AC(HU) hulking coast with two medium AK(SHU) in line ahead formation, distance 900 yards; the leading AK on port quarter of AC, distant 1100 yards. Second medium AK followed at a distance of 2000 yards by a pair of small AK's(HU), the leading one about 900 yards to the left of the medium AK's track, the second one two points abaft its starboard beam and on the medium AK's track. Two DS or torpedo boat escorts protectin. convoy from seaward; leading escort broad on port bow of AC, distant 1700 yards, second escort broad on beam of leading AK, distant 1300 yards. Broad on port beam of second medium AK was a suspeetc Q ship, distant 3000 yards. A sinle mast was seen astern of the whole convoy which was thought to be another escort.

Ships probably sunk:
Medium AC(HU) and Medium AK(HU).

Damage determined by:
1(a) Torpedo explosion at time of run for second torpedo fired at AC; AC seen to be hit at this time. Torpedo explosion at time of run of fourth torpedo fired at AC. At this time periscope was on one of two near escorts. Breaking up incises heard before and after close depth charging started.

1(b) Two torpedo explosions for time of run of two torpedoes fired at AC. Periscope on escort. Breaking up noises heard before and until after close depth charging started.

24 August: The lubricating oil pump drive shaft sheared on 1 main engine, requiring renewal of a pump, drive assembly, and drive assembly bushings.
23 August: The lubricating oil pump drive shaft again sheared on 1 main engine, requiring renewal of a pump, drive assembly, and drive assembly bushings.
6 September: The lubricating oil pump shaft on 1 main engine sheared for the third time on this patrol. Cause of the casualties has not been conclusively determined, but measurements indicated: (1) That the after end housing plate is warped, and/or (2) The pump drive assembly bushing brackets, which are bored in line when originally assembled, were not bored perpendicular to the after end housing plate. The engine is apparently running, active actively now with a .032" shim under one end of the lubricating oil pump, but a very thorough once will be necessary during refit period.

7 September: Pitometer Log - The upper deck was broken off during depth charging. I. new stop was machined from stock and installed.

16 September: Inspection of the brushes of "3 main generator revealed that 30 brushes had loose or broken rivets and/or broken clips. The port motor on this generator had been found to be "J23" out of round on the last refit, and a cut had been taken to live a maximum of .005" out of room. Dial indicator readings show that the commutator is now .015" out of room. All the V-rig" hulls are tight; there is no visual evidence of loose bars. About ten commutator segments are apparently rising, but the cause is as yet unknown. The broken brushes were replaced.

17 September: Inspection of 1 main generator revealed several broken brushes and the fact that the after end of the commutator was .003" out of round. Replaced broken brushes.

18 September: The main snap-switches of both I.C. motor generator sets burned out. These switches (located over the starting panels in the pump room) were jumped out and removed. Those switches, which have burned out before, will be replaced by suitable knife-switches, as it is thought that they are overloaded.

(L) RADIO

Radio: Reception of BAYERS was good at all times; no serials were missed. Transmission difficulties were mainly occasioned by the continued reluctance of shore stations to use authentication. Three hours were required to clear PADLE Seven, the last half hour being spent in obtaining an authenticated receipt. On one occasion 3290 kilocycles was tried, with nasty statistics showing interest, but none able to authenticate.

No new types of jamming or deception are encountered.

The VHF antenna installed just prior to the beginning of the patrol, was not of sufficiently rugged construction. The whip carried away on the first dive. The second antenna, installed at EMICUTA also eventually carried away and leaked continually after installation. Leaks were found around the whip entry into the top

(V) RELAYS

It is believed that the major part of all traffic in
the SULU SEA follows the coastline closely and anchors overnight.
Night contacts in open sea area are less likely to be made than day
contacts close to the beach. The adventures of the light camou-
flage for night attack therefore cannot be utilized and the light
color is believed to be a definite handicap when patrolling sub-
merged close to the coast in the consistently calm, clear water.
The darker gray camouflage is considered preferable for boats
operating in this area.

Subject: U.S.S. PADDLE (SS263) - Report of Fifth War Patrol.

1. The fifth war patrol of PADDLE was conducted in the EAST SULU SEA and lasted thirty-four days, twenty-one of which were in the area.

2. Ship contacts were few but PADDLE made one daylight submerged attack on an escorted convoy off SINDANGAI POINT. Four torpedoes were fired at an AO which gave one hit observed and one heard. Fire was shifted to an AK and two timed hits were heard. Further observation of damage was precluded by depth charge attacks by two escorts.

3. Voyage repairs were accomplished by ORIC!, among which was the stoning of commutators on No. 1 and No. 3 main generators to remove the eccentricity caused by high bars. The No. 1 main engine housing where the attached lubricating oil pump makes up a found sprung, which is believed to be the cause of pump failure. Temporary shims were installed to prevent distortion of the pump housing, and satisfactory operation has been obtained.

4. The Squadron Commander congratulates the Commanding Officer, Officers, and Crew for the damage inflicted on the enemy.

Comment on:

1. PADDLE's Fifth War Patrol was conducted in the SULU SEA Area.

2. PADDLE made one torpedo attack on a small convoy which was closely hugging the Coast of SINDANGAN POINT, MINDAKAO. An attack position inside the escorts and within 3,000 yards of the beach was obtained to insure success. The results were gratifying. Two of four timed hits were seen before a very close escort forced deep submergence. An accurate and extended depth charging followed. One medium AO was sunk and one medium AK damaged in this attack.

3. A "9" ship sighted by PADDLE was observed to be similar in appearance to a small AO, and was equipped with echo-ranging gear. It apparently depended primarily on listening devices when searching or attacking.

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

5. The Force Commander congratulates PADDLE's Commanding Officer, Officers and Crew on this aggressive patrol in which the following damage was inflicted on the enemy:

2152 Leading ship of target group speeded up and headed toward. PADDLE put ship astern and commenced running back down joint lane at full power with surface ship gainly slowly. To had been warned that we would pass U.S. Submarines in the joint lane, but we had no warning of friendly surface units, so at

2158 With target at 9,300 yards and closing, sent contact report to Commander Task Group 71.5 and asked if contacts were friendly, using MIDS CREDIT ship-shore frequency of 355 Kcs. 'hile trying to get contact report through over the volume of routine traffic on the circuit, target closed to 7,700 yards, so at

2200 Attempted to exchange recognition signals as our presence was already obviously known. Target failed to carry out proper recognition procedure, but finally gave the second reply and the call of DD502 Incorporated her call in contact report. Target continued to close steadily.

2203 'It's target at 7,500 yards, requested her to cease chasing. She promptly reversed course and headed up to the northeastward, to rejoin her group. Decided to trail targets at ranges of 19,000 to 20,000 yards until positively identified as friendly because of the unexpected appearance of these ships and the difficulty of exchanging recognition signals coupled with memory of reports of compromised recognition signals.

0701 In position Lat. 01°14'S, Long. 117°39', sighted large, two masted schooner Bearing 199°T, distant about 7 miles. Encounter was near position of our initial point. Decided to investigate. (Ship Contact 1).

0723 Schooner was larger than the usual small boats ordinarily seen in this area. Radar had a good pip at 8900 yards. Saw what may have been a radio antenna between the two masts. Manned 4 inch gun and both 20mm guns.

0737 Close observation showed boat to be a schooner of about 50 tons, very low in the water and carrying a great spread of canvas. Still looked like a radio antenna. Saw six Japanese heads sticking up in the stern-sheets watching us intently. Because of our proximity to land and our assigned mission, did not want to board and risk chance of being forced down with a boarding party in the schooner, so at

0738 In position Lat. 01°20'8", Long. 117°36'3", fired one round of 4" into hull of schooner, still holding both 20" guns for possible snipers. Schooner shuddered, stopped, rolled over and sank in seven seconds. She must have been full of metal or ore to have given us the good pip we had on the radar and to pull that substantial wooden hull under so soon. Crew of six would have no part on coming on board; Left them for the sharks.

0315 Patrolling on surface on lifeguard station. -Hile on lifeguard station usually patrolled at one engine speed circling, zigging, cutting figure eights and irregular figures. This speed made little wake to be sighted by a plane and was still fast enough to make a torpedo shot at us very difficult.

0909 SD contact at 6 miles, opening. Sky was eight-tenths overcast with low cumulous clouds so plane was not sighted. Contact faded out at 0911 at 8 miles. (Aircraft Contact 11).

"Ith strike probably now in progress, decided that staying on the surface in order to receive any messages from our planes was most important. Slowed to four knots to reduce our wake. Kept plane under close observation as it continued on steady course. Had been trimmed 5000' heavy since commencement of lifeguard duties. Plane continued on its way and disappeared into the clouds at a range of 8 miles.

1329 SD contact at 14 miles. (Aircraft Contact '27). Contact faded out at 1331 at 12 miles.

1419 Arrived at report location of ten airiators. Nothing in sight. Commenced spiral search plan at three engine speed, with this point as the origin, distance between adjacent track's six miles. (Assumed our limit of visibility for near in water for existing smooth weather to be three miles). Stationed an officer on each periscope, one searching on each beam, and maintained a total of six lookouts on the bridge. Used three engine speed because the extra twenty-five turns outside from the fourth engine caused the periscopes to vibrate enough so as to react an efficient periscope watch.

(Cont'd.) at ranges of 7 to 8 miles, until at
1507 Plane was sighted from the bridge bearing 032°T,
apparently circling a spot on the water. Slowed to
4 knots to reduce wake and observe plane. Identified as a "LILLY" type bombing plane. SD indicated
that plane approached us closer with each circle
that he made, so at
1514 With range of 53 miles, dived to periscope depth
to observe plane. As barrel of periscope went under,
the plane was lost to sight because of the vibration
of the periscope, on 042°T, still circling. Never
able to regain contact.
1545 Surface. Proceeded on surface at three engine
speed on spiral search plan. The location of the
circling plane when plotted on a chart, fell within
half a mile of a track we had previously run on the
search plan.
1550 Sighted two small sailboats bearing 050°T, and 035°T,
respectively. Decided to investigate on in the be-
lieft that our aviators might have been picked up by
them.

natives. They apparently had seen no "white bird
men".

The closer we approached, the more his arm-waving diminished, until when he was 20 feet off, he was definitely seen to be a Jap in a Japol life-jacket. He showed no inclination to be taken on board, so in view of the prospect of having numerous aviators for passengers and the probability that we could take the Jap on board only in a wounded condition, proceeded with search.

1910 Completed search plan. We had covered a 452 square mile circle of the center of the point given as the location of the ten doomed aviators. Proceeded at four engine speed to point where group of five airmen were reported down.

2104 Arrived in reported position of five doomed aviators. Slowed to one engine speed and commenced spiral search with given location as origin. Assumed limit of visibility to be 1000 yards, hence one mile between adjacent legs.

0404: From a position sharp under the port quarter of leacinq sea-truck, opened fire with 4" gun and both 20" guns. First two 4" shots missed. 20" rated bridge and main deck. Teld 30 and 50 calibre machine guns as in attack on trailin sea-truck to wipe out any enemy machines gunners and to always have two guns ready to shoot at any time. "o enemy fire encountered in either case. Third 4" shot hit. Trailing sea-truck traced awar on course 2350T, speed 6 knots, probably her top speed. Permitted 30 and 50 calibre machine guns to shoot a few rounds for training. Kept way on PADDLE at all times, varying course and speed.

0411: After 20" gun succeeded in setting the bridge on fire and at

0413: A 4" hit started a good fire amidships. Continued pumping hits into hull to spread the fire and sink target.

0424: Entire target burning well. Dozens of 20" holes about 8" in diameter were made visible by illumination of fire. Noted a radio direction finder on the top of the bridge. Target was not in flames from stem to stern, from water-line to the top of the bridge and the top of the foremast, and settling slowly. Started after other target at

0425: The had opened to about 3000 yards. Apparently a few hands had come up from below decks and named the bridge, as target tried to ram on several occasions.

0431: Resumed work on trailin sea-truck, keeping him silhouetted against illumination of leacinq sea-truck.

0439: Target was now in full flames and settling very slowly. Smoke from fire of both sea-trucks smelled like smoke from burning crude or bunker oil. First target set on fire was seen at least six times to flare up brightly amidships and a sizeable puff of flame and smoke arose - possibly oil drums on deck.

PERFORMANCE, CARE AND UPKEEP OF MARK 13 TORPEDOES WITH RECOMMENDATIONS AND COACHES

No Mark 13 torpedoes were fired on this patrol.

While undergoing a short refit alongside the U.S.S. CRION at MIOS HONDI, a battery explosion occurred in torpedo #53722, which was loaded in tube #9. The explosion was caused by inadvertently turning on the hydrogen burner before the torpedo had been properly ventilated. The torpedoman had previously connected the leads from 9 tube to the jacket box for #7 tube, hence when the burner circuit for #7 tube was turned on, the burner in #9 tube was actually energized.

The force of the explosion pushed out the after bulkhead of the battery compartment, the after bulkhead of the war head, and knocked the tops off of several cells. The after-body and the exoloder were undamaged. The torpedo was replaced by the U.S.S. CRION.

Other than the above casualty, no difficulty was experienced with maintenance.

It is recommended that the battery compartment be constructed with longitudinal steel-members. Is presently constructed, if a Mark 13 torpedo is carried on more than one patrol, it becomes more difficult to load because the battery compartment is not rigid and it begins to assume a corrugated contour between ribs.

(V) REMARKS

It is believed that little if any Japanese shipping is currently traversing KASKAS STARIT, although there is still considerable air activity in the area.

It was noteworthy that no APR-1 contacts were made in either SIAGE PASSAGE, KASKAS STARIT, or LOMBOK STARIT.

Friendly fighter cover for lifeguarding submarines would greatly enhance the help that the submarine could furnish, by allowing uninterrupted surface running during the strikes when a message is most likely to be received from the planes a.d during a search by the submarine. To fighter cover whatsoever was contacted while on lifeguard duty.

Subject: U.S.S. PADDLE (SS263) - Report of Sixth War Patrol.

1. The sixth war patrol of PADDLE was conducted in MAKASSAR STRAIT and was of thirty days duration, twenty-one of which were spent in the area.

2. PADDLE was stationed for lifeguard duties but made no contacts with downed aviators. No targets for torpedoes were encountered but in two gun actions a 50 ton schooner and two 500 ton sea trucks were destroyed.

3. With the exception of the corvettes on No. 1 and No. 3 main generators, PADDLE is in good material condition. It is regretted that the fault with those generators is one which can not be permanently repaired until design changes have been made to the available spares. Both corvettes will be turned to give best practicable performance on the next patrol.

4. The Squadron Commander congratulates the Commanding Officer, Officers, and Crew for the damage inflicted on the enemy and hopes that succeeding patrols will bring better opportunities for action.

1. PADDLE's Sixth War Patrol was conducted in MAKASSAR
STRAT, and was the first under her present Commanding Officer,
Lieutenant Commander J. P. FITZ-PATRICK, U.S.N.

2. This patrol was one in which the primary mission was
lifeguard duties in the BALTICAN AREA, with very short periods
off for normal offensive patrol duties. No rescues were effected.

3. Major targets did not present themselves, but of
three minor targets sighted, all three were expeditiously attacked
and sunk by gunfire. The attack on two-oil-laden sea trucks in
company was particularly well conducted, and resulted in many minor
caliber hits and thirty eight four inch hits. There were no
casualties to any gun or ordnance equipment on PADDLE.

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

5. The Force Commander congratulates PADDLE's Commanding
Officer, Officers, and Crew on this first patrol, and predicts more
targets and a bigger bag on succeeding patrols. The following
damage was inflicted on the enemy:

While opening from escort, the escort commenced firing a four inch gun in our direction. Commenced opening at full power. Escort commenced firing 400M shells in our direction. All gunfire was on in deflection but somewhat off in range. Visibility at the time was highly favorable for us with our light gray paint; decided we were detected electronically. The range of the torpedo pointed more to a radar detector than the use of radar itself. HAMMERHEAD and MINGO now had contact. Escort continued chasing us, maintaining a zero angle on the bow. Occasionally visible to our best night lookout using 936B binoculars. Each time we altered course the escort followed us right around. Told other boats we were drawing off port bow escort.

After torpedoes had been running for a minute, plot reported that escort had changed course to the left. All torpedoes missed. Escort apparently had seen torpedoes pass him, because at this point he broke off the chase.

and headed back in the direction of the convoy. Commenced running to eastward to get into a position ahead of the convoy to attempt to squeeze in between this escort and the convoy for a port flank attack. Reloaded aft.

2328
In position ahead of convoy on their track looking for an opening. MINGO reported being sighted and subsequently that two starboard escorts were chasing him. This looked like our opening. Started down track of convoy intending to attack most lightly protected flank, presumably the starboard. A convoy zig at this time would only help the situation.

2332
Picked up MINGO on SJ on a northerly course making 18 knots, and right behind her two escorts close together making just about the same speed. Passed all port to port. The escorts never seemed to notice us. Commenced pulling out to eastward to get off track of convoy. Solution was fair what with the pitometer log being erratic and undependable. In order to insure enemy damage decided to move in quickly and fire from a relatively short range.

2350
Had a good picture on the P.I. Convoy now consisted of four large ships in two parallel columns of two, with a large escort on the starboard beam of the leading ship in the near column and two smaller escorts on the starboard quarter of the trailing near large ship, with probably two port flank escorts. This made a total of 7 or 8 escorts of varying sizes, counting the two that were chasing the MINGO. Picked as target the trailing ship of near column and commanded attack as this ship was overlapping the two ships of the far column.

Commenced swinging away to bring stern tubes to bear on target group. Obtained four sighted and timed hits in target which immediately burst into flames. Tanker was probably laden with gasoline. Escort on starboard beam of leading tanker turned toward and commenced firing a 4" gun and much 40mm and 20mm in our direction - most of it quite close. Two smaller trailing escorts caught on right away and opened up also.

0008
With most of the trouble coming from this former starboard beam escort who was now making 17 knots, fired four stern tubes set at 3 feet, gyros near zero, torpedo run 1360 yards. Obtained one timed and sighted hit which got him on the starboard side about amidships as he was giving us about a 30° starboard angle on the bow. He quickly listed to starboard and stopped. The crew started jumping over the side except for a few people on the guns who didn't want to quit. Identified target as a WAKATA class destroyer (EU). Tanker had gone under by now, but the large oil fire remained on the surface brightly illuminating the area. The two small escorts continued to chase us away from the firing position. At about this time our destroyer was lost to sight. The Executive Officer was on a periscope watching him and sighted his view on to the other two escorts. When he next looked back at the destroyer it was not in sight although conditions of illumination were still the same. In retrospect, it is recalled that gunfire from the destroyer stopped at about this time although not much thought was then given it as the two smaller escorts were keeping up a brisk fire. It is believed that the destroyer sunk. Commenced r.l.d of one tube at a time while opening slowly from two trailing escorts. Hoped to run up to northward to get in another attack. MINICO reported she was still being chased. HAMMERHEAD reported convoy had changed course to the westward.

(C) WEATHER
The weather in the SOUTH CHINA SEA was generally very heavy, with few days of good torpedo weather. Condition six to seven seas existed most of the time, accompanied by heavy overcast.

West of LUZON the seas were quieter, but a long heavy swell prevailed. Skies in this area were generally clear.

Northwest of LUZON heavy seas and overcast were again encountered.

(D) TIDAL INFORMATION
In general, the current in the SOUTH CHINA SEA set toward 185°T to 220°T, drift varied from 1.5 to 3.3 knots.

West of LUZON little drift was noticed - usually less than .3 knot.

The change in direction of current from south to north when crossing the middle of the SOUTH CHINA SEA from the west as predicted by the Shilling Directions was most noticeable.

Northwest of LUZON a slight southerly set was experienced.

(E) NAVIGATIONAL AIDS
No new navigational aids were found. No navigational lights were observed to be in operation.

Navigation in the SOUTH CHINA SEA was difficult because of the currents and overcast.

The LORAN equipment installed during the last refit proved most satisfactory when within range of LORAN stations. The equipment fulfilled the highest expectations.

(J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS

The conditions of visibility on the night of 7-3 December were such that the PADDLE could not have been sighted at a range of 2,000 yards at the very extreme, however the escort started firing at us, deflection right on, at a range of 7,000 yards. It is thought that this convoy had one detector equipped escort on each bow. To encounter the port bow "detector" and lost him at about the time the MINGO started drawing off the starboard bow "detector". In going in for an attack as the MINGO was pulling out, we unintentionally passed the two escorts that the MINGO had in tow at about 5,500 yards, a range we would have avoided were it not for the high relative speed of thirty-six knots, yet neither of those escorts detected us. If they had detector equipment, it is possible that it is highly directional and was trained on the MINGO. As both escorts were close together, it is believed that one non-detector-equipped escort trailed along keeping position on the detector. Visibility was actually such that we were not sighted prior to firing at 2,000 yards and then only in the illumination from the oil fire.

On 31 December a motor-boat believed to be a sound listening boat patrolled by us off CAIMAN POINT. Shortly after he disappeared in the north a PC patrolling southward carried out a random depth charge attack 3,000 yards away from the PADDLE.

The most effective anti-submarine measure encountered was the radar equipped airplanes operating night and day. It is believed that planes search at a fairly high altitude (witness the number of SD contacts on initial APR contacts) and then drop down very low to cut down the sea-return on their cathode ray tube and to get under our SD pattern. It is further believed that planes then came down the "counter-bearing", rocking the plane right and left a few degrees, and reducing radar power as they approach so as to create the illusion on our APR of not closing the distance. Several instances of radar planes using consistent power but "keying" have been noticed - in other words a contact would come in weakly, then disappear; then come in stronger and disappear; then stronger still and disappear. While clearing the bridge on the "barge" instance, a very strong signal came in and a plane passed within two miles of the ship, very low.

— page 303 —
29 November 1944 - The Pitometer Log went out of commission and required constant work and attention during the patrol. Trouble was experienced in particular with a broken pump drive coupling, corroded bellows pivot arm bearings, and electrical maladjustment.

(L) RADIO

All radio equipment functioned with but minor casualties. Reception of fox broadcasts was generally fair, except in the area northeast of LUZON where PM was blanked out for periods up to six hours daily. VIXO reception was best on the 9MC band at night, 12 and 16MC during daylight. Several of VIXO's frequencies, while strong enough, seemed to have a constant small drift of frequency requiring continuous tuning.

Transmissions to CTF 71 Wore all cleared on the 4145 series with VIXO answering on BAKERS. This procedure enabled the PADDLE to remain on the air for a much shorter period than during previous patrols when answering was all done on the calling frequency.

Wolf pack communications wore satisfactory in spite of various station shifts. Frequency shifts were carried out in accord-ance with WONAOO 2 but the advantages of this were partly nullified by frequent transmitter tuning during the first ten minutes of each new frequency period by various units. PADDLE was able at all times to clear messages without previous tuning and usually with little output registering on the transmitter. CW is still the most reliable method of transmission although this may prove unhandy when using the conning tower remote control station.

(M) RADAR

The SJ-a radar gave satisfactory performance during this patrol. Maximum range on a ship target was 24,550 yards, on a probable heavy cruiser.

No operational time was lost and no failures occurred but continual trouble was experienced in keeping satisfactory sensitivity. Four 721-A tubes were used. The spare allowance in this item is inadequate to maintain the radar in top operating condition throughout a patrol.

Subject: U.S.S. PADDLE (J263) - Report of Seventh War Patrol.

(M) RADAR (Cont'd.)

The SD radar gave good operation with no failures. Ranges were satisfactory, but as in the past, low flying aircraft were not usually picked up.

APR

The addition of an SPA pulse analyser increased the value of the APR. Atmospheric and internal interference could usually be quickly differentiated from bonfire radar contacts, and the action of a contact is more quickly and easily discovered by sight than by sound, although the phones were used continuously as before. Random noise or internal interference constantly triggered the pulse repetition frequency counting circuit so that weak contacts usually would not give a p.r.f. reading, however as soon as the signal strength increased enough to override the random noise, accurate p.r.f. readings were obtainable. The SPA unit was operated at all times when the APR was in use.

(N) SOUND

Sound conditions were generally good in the SOUTH CHINA SEA and WEST LUZON areas in spite of the heavy weather.

No echo-ranges were attempted.

(O) DENSITY LAYERS

In the SOUTH CHINA SEA there was a noticeable absence of gradients - usually only one degree down to 200 feet.

At 1500, 1 December 1944, an eight degrees negative gradient was found in position Lat. 10°34' S, Long. 115°37' E, between periscope depth and 120 feet.

(P) HEALTH, FOOD AND HABITABILITY

The health of officers and crew was exceptionally good this patrol.

Food was adequate and well prepared.

1. The SEVENTH war patrol of the U.S.S. PADDLE was conducted in the SOUTH CHINA SEA and the WEST LUZON areas. The PADDLE was one of three submarines forming a coordinated attack group. The patrol was of fifty-five days duration.

2. Only three contacts were made worthy of torpedo fire, and of those three, only one could be closed for attack. This was a convoy of tankers heavily escorted by many destroyers and destroyer escorts. The scries of attacks made by the PADDLE on this convoy were outstanding in aggression and tenacity, the results were extremely satisfactory. A summary of the attacks follows:

TORPEDO ATTACK NO. 1 - 7 December 1944 - This was a surface radar attack made late in the evening against a Japanese destroyer or destroyer escort that had detected, probably by radar, the PADDLE and was chasing it firing all types of guns in the chase. The PADDLE fired three Mark 23 torpedoes in a "down the throat" attack; however, the destroyer or destroyer escort changed course prior to the arrival of the torpedoes and returned to the convoy. It is possible that the torpedoes were sighted and that this discouraged any further anti-submarine measures on the part of the escort vessel.

TORPEDO ATTACK NO. 2A - 8 December 1944 - About an hour and a half later the PADDLE was able to close in on the convoy of tankers again and making another surface radar attack, the PADDLE fired six Mark 23 torpedoes at a large enemy tanker obtaining four good hits which immediately set the tanker on fire. The tanker sank shortly afterwards.

1. The seventh war patrol of the PADDLE, under the command of Lieutenant Commander J. P. F. Patrick, U.S. Navy, was conducted in the South China Sea and West Coast areas. The PADDLE patrols in a coordinated attack group along with the U.S.S. HERRERA (SS364) and the U.S.S. LAPON (SS260), with the commanding officer of the HERRERA in command of the group. Later she patrolled with the U.S.S. BEGUIN (SS319), the U.S.S. FLASH (SS249), the U.S.S. LION (SS247), and the U.S.S. HOE (SS255), with the commanding officer of the HERRERA in command of the group; as well as at times conducting an independent patrol.

2. This alert and aggressive patrol resulted in three worthwhile contacts, one of which could be closed for attack. This contact consisted of a convoy of four large tankers with seven escort ships. Two atoll, aggressive attacks were made. The first attack, which was unsuccessful, was delivered on a destroyer which had detected the PADDLE and was attempting to drive her away from the convoy. In the second attack, made in the face of heavy gun fire from the escorts, one destroyer and one large tanker were sunk.

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

4. The Commander Submarine Force, Pacific Fleet, congratulates the commanding officer, officers, and crew for adding another aggressive and successful patrol to the PADDLE's already illustrious record. The PADDLE is credited with having inflicted the following damage upon the enemy during this patrol:

Four days for voyage repairs, most of which work extended over into the eight day training period which followed. Commander L.D. Jac Gregor, U.S.N., Training Officer, was most helpful in his suggestions and constructive criticisms. Fired all torpedoes for hits.

During the voyage repair and training period, the following equipment was installed:

Torpedo Detector Modification to QB Sound Gear. Installed RBS receiver in Radio Room and relocated RBB to wardroom. Installed SCR-610. Installed 66AJO antenna. Installed LFR-5AX and antenna. During one days delay for dry-docking for work on negative tank liquidometer, completed blast-phone instillation of D.C.D.I.

Two days for loading, and ready for sea on 15 May 1945.

From various printed matter formulated plans for petrol, some points of which follow:

(a) "Hill not use SD radar at all, except just prior to surfacing, at which time it will be kept once at 50 feet to detect any close overhead planes. At all other times will depend upon an efficient LR watch and efficient lookouts to detect aircraft.

(b) "Hill search for surface targets during periods of low visibility using the ST Radar, listening every ten minutes on the SD to detect presence of similar radar. Based decision for search on ST on fact that deep probability cannot detect it, plus results of study of its performance which showed consistently greater range on some target than St since departure Bay 1/2c - for instance our 2,0,1, escort into SHIP - 15,520 yards on ST, 14,250 yards on SD.

(c) "Hill must at all times on surface while making dive on deep or loose or less.

(c) "Hill 2 - zig zag at all times.

(c) From centre of last five months (with most aircraft on contacts of last two months), will escort calculate in following positions:

2344 (I) In position Lct. 34°06'E, Long. 126°12'E, divcd. Fired one each of MAE, MAC, and FTS. Turned to northward and ran about a quarter of a mile. Bottomed in 21 fathoms. Scoured everything except gyro. Decided this action to be best, as poor sound conditions, soft mud bottom, currents and pest experience echo-ranging for a bottomed submarine under more favorable conditions had showed the more in- possibility of locating the submarine. Would have to get into deeper water before they could get magnetic plenus out at dawn. JP was invaluable in keeping track of the three targets. Heard much echo-ranging and occasional scares.

9 June 1945

0353 (I) All echo-ranging appeared to be fairly weak and to the northnortheast. Decided to move to deeper water.

0356 (I) Off the bottom. Standing out to southward, piloting past three foot shoal by JP and JK bearings on surf noises from spot.

0543 (I) Group commenced another high speed attack down to southwest to the east of us, then across to the northeast about 500 yards. Very strong sound indicated changing speed while on passage, fading of scares indicated frequent zigzags. Considered characteristics and tactics of hunter-killer group and decided on evasion.

— page 329 —
9 June 1945 (Cont'd.)
0730 (I) Bottomed in 190 feet of water. Persistence of search of group as they swept back and forth across our path, reappearing forward of our beam, dictated laying low for a while.

0830 (I) During the next fifteen minutes, group dropped a total of sixteen depth charges off to the southward.

1200 (I) Noon position: Let. 3403N, Long. 12606E.

25 June 1945
0424 (I) In position 18 miles, 120°T, from SHOEHEI TAO, dived for submerged patrol, heaving failed to close coast to desired position because of having been engaged in chasing and tracking verious, numerous ST contacts picked up at 12,000 to 18,000 yards. In each case target tracked at speeds of from 0 to 3 knots, and were closed to 8,000 yards and identified from bridge in moonlight as sailing junks. Extreme ranges probably result of surface trapping, as we received SJ interference from two other boats believed to be 110 miles away. Commenced closing beach submerged with the aid of a 3 knot northwesterly current. During forenoon had some small craft traffic as on the twenty-third. One small vessel, a steam driven "motor launch" class of 30 tons (EU), passed close aboard in position Lat. 38°48'N, Long. 121°26'E at 0948, bound for EN TO. Charted depth this position 24 fathoms, with heavy surf nearby. (Ship Contact #9).

Simultaneously received garbled contact report on us on coordinated attack frequency from SPOT, but as SPOT's position was not given therein and his SJ interference was weak, assumed for present that we might both have contact on a target between us, because as far as we knew, SPOT should be at least twenty three miles away. Picked up some SD on I.P.R. Sunk SPOT our position on coordinated attack frequency. SPOT asked us if we had received TRINITE dispatch 070707 to which we replied in the negative and asked for the dispatch. Naturally closed SPOT then broke off tracking. Decided we had missed TRINITE dispatch 070707 on trim dive this afternoon between 1631 and 1647.

2004(I) Date: 8 June 1945. Lat. 33°38'N, Long. 126°22'E.

Description: Small, leden, Japanese FE(EU) of about 2,000 tons, unscorcted, bound from S.ISHU on island of S.ISHU TO to KOREA. RICHIPILAGO.

Ships Sunk or Damaged: None.

Damage Determined by: None.

Target Draft: 7 feet. Course: 005°T. Spced: 10 knots. Range: 1500.

Type Attack: Day submerged periscope attack using Type 4 periscope with ST rengos from the time target was picked up on ST at 7,500 yards until target was closed to 3,300 yards, at which time attack was shifted to 1,411' periscope and a mast height obtained using range generated since last ST set-up (about 15 seconds). Continued attack on 1,411' periscope with solution continually chocking like a sub-school set-up. No echo-range attempted because of exact determination of set-up from ST date and determination of mast-height.

End of run explosions were heard five and one half and seven minutes after firing first torpedo. Sound tracked torpedoes on proper bearing, apparently running properly. After first torpedo explosion, took 35 set-up on target and found that observed and generated set-up should within two degrees and 35 yards. Torpedoes may have failed to hit because of large gyro angle necessitated by events prior to firing which dictated above choice of firing set-up.

TARGET DATA - DATABASE INFLICTED

Description: Target was leading ship of a pair of pursuing submarine chasers of the 20-1 class (EC) that had detected us as we were making a night surface approach on them. Conditions of visibility were such that we were detected by radar, either from a station on a near island or by the sub chasers themselves.

Ships Sunk or Damaged: None.

Damage Determined by: None.

Target Draft: 5 feet. Course: 264°T. Speed: 10 knots. Range: 2300 yds.

ON SHIP DATA

Speed: 16 knots. Course: 262°T. Depth: Surface. Angle: Surface.

FIRE CONTROL AND TORPEDO DATA:

Type Attack: Night surface. Contacted two sub chasers by SJ radar while picking our way through south-eastern approaches to NIKIOTSU SUDO. Commenced surface tracking for attack on starboard quarter of target group as they proceeded in company. Keying SJ radar to obtain set-up. Noticed blinker light signalling from island on the other side of targets, then shortly thereafter near target headed toward. Stung stern to end him for storm shot, whereupon he gave us a fifty degree port angle on the bow - came right for bow shot. Target again headed toward quickly. Stung to bring stern tubes to bear. Target opened up with a 3" gun, fairly close. Fired two torpedoes and commenced opening at full power.

Sunk: One Japanese sailing cargo carrier of 100 tons (E).
Damage determined by: "Intense target disintegrate. Remains caught fire."

DETAILS OF ACTION:
Closed target to 1200 yards and tore it up completely with ten rounds of 5" IC. Closed to 50 yards and set it on fire with four cruses of 20mm ammunition. Left burning, mass of wreckage on surface of water. Spotting as in Gun Attack No. One (a).

(I) MINES
Twenty seven floating mines were contacted this patrol including the probable mine that we struck before dawn on 7 July. All mines sighted were either sunk or exploded except for this mine and the one we were shooting at on 2 June when we had a possible torpedo contact on the TD.

Fifteen mines exploded and ten were sunk as a result of .30 caliber rifle fire.

(J) ANTI-SUBMARINE TERRORIST ATTACKS
The Jap Hunter-killer group contacted on 8 and 9 June had one member who used 2M K. sound gear. This was probably a fairly experienced team as they stuck to the job for twenty-one hours (possibly more), spent at high speeds, and zig-zagged frequently while sweeping. Their surface gunfire was quite accurate, and after they built up to speed, it could probably be impossible to evade them on the surface. The Hunter-killer group contacted in the DARIH area on 25 June seemed less effective.

3. (I) RADIO (Cont'd.)
4. Three .006 Mf condensers, two in the transmitter end one in the receiver, exploded possibly due to condensation and continuous operation and inadequate cooling resulting in overheating the set and exceeding the limits of these condensers.
5. The remote control unit in the coming tower was used frequently, and an effort will be made to provide a similar station on the bridge in portable form during the coming refit.
6. (II) RADAR MATERIAL
7. The addition of an ST unit during the recent Navy Yard overhaul provided a means of searching without the possibility of being DFI'd. The ST was used only after an ST contact and was then keyed. The ST was manned continuously in the area at night and during periods of low visibility.
8. With proper tuning, ST ranges were superior to ST, but a slight variation in periscope height detunes the ST with a great reduction in range. Then in use, it is necessary to keep a constant check on ST tuning. With some experience, ST bearings could be obtained with an accuracy of about 3 degrees, by turning the periscope for maximum pitch height.
9. Spotting for both the 5th gun and the 40th was accomplished by using the ST to correct ranges, and No. 1 periscope to give deflection errors. The video beam pattern of the ST enables much easier and quicker spotting, with better fire control, then was possible using the ST.
10. ST operation in general was very satisfactory, and the experience gained in its use will make it increasingly valuable in the future. Technically, no major difficulties were encountered with the equipment, except the need for constant checking on the tuning to insure maximum sensitivity. Five crystal detectors (Item Y-1) in the r-f line were used. Either the crystals are not designed for the type of operation given the set, or we had an especially poor lot, as frequent replacements were necessary to give good operation. If this condition is typical, an increase in the allowance of this item is recommended.

(U) RADAR AND RADIO COUNTER-MEASURES

No identified Japanese air-borne radar "as encountered, and only one possible ship-borne signal. All others appeared to be shore based, early-warning, air search radar.

One such installation was observed through the periscope on GYU TO, east of SAIISHU TO. A large bed spring type antenna, with a slight tilt of about four degrees, seemed to be mounted on the roof of a small building. The frequency could not be established positively in later checks, but apparently it was 155 Kcgs.

(U) - RADAR AND RADIO COUNTER- MEASURES (Cont'd.)

Another possible installation was observed near the lighthouse at CHOSAN KUN, but no details could be observed because of the range. The antenna appeared to be a large bed spring type similar to the first.

No radar or sonar countermeasures were encountered. Radio countermeasures consisted of C.W. jamming and at one time a noise modulated signal.

(V) REMARKS:
It is regretted that torpedo results were not better, but any one or all of the following factors may have been the cause:

Possible deep running or erratic torpedoes.
Possible shallow draft targets.
Intense desire to sink enemy shipping, causing ship to shoot at small targets that would not have been attacked several months ago.

It is felt that the material condition of the ship in general is much better than usual after coming out of a very yard overhaul - this is probably a direct result of the excellent workmanship of the Bethlehem Steel Company Submarine Repair Basin resulting from the close cooperation between ship's officers and crew with the Steel Company representatives and workmen during the overhaul, and the subsequent untiring attention to details of routine and upkeep by ship's officers and men.

The floating mine concentration in the YELLOW SEA has seemed to have moved northward about forty miles.

Probably no shipping whatsoever crosses the YELLOW SEA any more. SHANGHAI-EMPIRE traffic is probably exposed to submarine attack only just south of PORT ARTHUR and off CHOSUN KIT at the letter piece 6 to 7 knot currents will make submerged patrols very difficult.

Subject: U.S.S. FADDLE (SS263) - Report of Eighth War Patrol, Comments on.

1. The eighth war patrol of the U.S.S. FADDLE under the command of Lieutenant Commander J. F. PITZ-PATRICK, U.S. Navy, was conducted in the Yellow Sea and East China Sea and covered a period of sixty-five (65) days, thirty-six (36) of which were spent in assigned areas. The FADDLE was a unit of the concerted search and attack group, consisting of six submarines under the command of Lieutenant Commander G. L. STREET, U.S. Navy, commanding officer of the U.S.S. TIRANTE.

2. Area coverage was excellent. Only eight days were spent submerged out of the thirty-six (36) days in the area. Torpedo targets were scarce. Three torpedo attacks were made, none of which were successful. A possible attack on a Japanese RO Class submarine was frustrated by the appearance of friendly planes which caused the Jap to dive. C notact could not be regained.

ATTACK NO. 1. This was a submerged daylight attack on a small 500 ton SC proceeding unescorted, and hugging the coast line. Three Mk 18-2 torpedoes were fired from the bow tubes on an 80" port track, with average gyro angles 12 ft, torpedo run of 2100 yards, torpedo depth set at 3 feet. Set-up was excellent but all torpedoes missed. Two torpedoes exploded on the beach. At least one hit should have been obtained with the spread used. Misses cannot be explained.

ATTACK NO. 2. This was a day submerged attack on a single unescorted FB of about 2000 tons. Tracking was done by ST radar until the latter stages of the approach. Two electric torpedoes were fired from the stern tubes on a 135" Port track, depth set at 3 feet, torpedo run 1500 yards. Gyro angles were large, 57 ft. The spread used (1/4"L, 1/4"R) was inadequate, giving a linear spread of about 60 feet between torpedoes. Misses were probably due to the large gyro angles, shallow draft of target, inadequate spread, or combination of these factors.

ATTACK NO. 3. While chasing the above target to retain contact, SJ radar contact was made on two patrol boats at a range of 3100 yards. After tracking targets, a night surface radar approach was started. Before reaching a firing position, the FADDLE was detected. One patrol boat turned toward the submarine and opened

fire with about a 3 inch gun. PADDLE fired two Mk 18-2 torpedoes from stern tubes on a small starboard track at 2300 yards range, torpedoes set at 2-1/2 foot depth, gyro angles 22°R. Both torpedoes missed probably because of the shallow draft of the target and the small track angle. PADDLE began retiring on the surface with enemy shells straddling her. Second patrol boat took up the chase and began overhauling the submarine at 23 knots. Shortly thereafter a third vessel was detected by radar, joining the chase and PADDLE was forced to dive. These three vessels turned out to be a Hunter-Killer group which was exceedingly persistent in their search. They kept the PADDLE down for 21 hours. Upon diving the Commanding Officer fired several beacons and then bottomed in soft mud in 21 fathoms of water. These tactics were successful in preventing the searching vessels from locating the submarine. Sixteen depth charges were dropped, but no damage was sustained by the PADDLE either from the depth charges or the enemy gunfire.

3. The PADDLE took advantage of every opportunity to destroy enemy small craft encountered. The shooting was excellent in all cases with the percentage of hits being very high.

GUN ATTACK NO. 1. On the morning of 8 June, while submerged, two small motor picket boats were sighted. PADDLE made a "battle surface" and at an average range of 1500 yards demolished one boat with six 5 inch hits out of eight rounds fired. During this action two Jap "Bettys" were sighted 8 miles distant. PADDLE stopped to reduce her wake and when planes went on their way without detecting the submarine, the second picket boat was closed to a range of 150 yards and demolished with 20mm gunfire. Enemy did not return the fire.

GUN ATTACK NO. 2. On the night of 27 June, a ship was sighted in the moonlight. Upon closing range, target was identified as a Japanese two-masted sailing picket boat of about 50 tons. Two 5 inch hits out of 5 fired at 1200 yard range disintegrated the target. Wreckage was then raked with 20mm fire from 50 yards range. Enemy did not return the fire.

GUN ATTACK NO. 3. Early on the morning of 2 July, two Jap sailboat pickets of about 50 tons each, were sighted. Range was closed to 1200 yards and one boat was demolished with six 5 inch hits. Second boat was demolished with 54 rounds of 40mm fire from 350 yards range. No return fire was encountered.

GUN ATTACK NO. 4. An hour and a half after attack No. 3, above, CJ radar contact was made on a target at 8000 yards range in a heavy fog. Target tracked at 6 knot speed. When fog lifted target proved to be a four-masted Jap schooner of about 250 tons. Another ship

of the same class and size was sighted anchored four miles away with sails down. Range was closed on the anchored schooner to 1200 yards, and schooner was demolished with 10 rounds of 5 inch, plus raking the wreckage with 20mm fire from 75 yard range. The other schooner doused sail and the crew abandoned ship. FADDLE closed to 980 yards range and one Mk 18-2 torpedo set at 1-1/4 foot depth was fired as a test shot, with small gyro angle and on a 90° track. It missed. Target was then demolished with 8 hits out of 11 rounds of 5 inch, plus raking the wreckage with 20mm.

GUN ATTACK NO. 5. During the afternoon of 2 July a brand new sailing cargo carrier of about 100 tons was sighted and from 1200 yards range, was demolished with 10 rounds of 5 inch. Wreckage was set on fire by 20mm fire from 50 yard range.

4. During the patrol several junks and fishing boats were investigated but were found to be Chinese and were not molested.

5. Twenty-seven floating mines were encountered, including one which the FADDLE apparently struck during darkness but fortunately did not explode. Twenty-five of the mines were destroyed by rifle fire. Ten sank and fifteen exploded.

6. Enemy aircraft contacts were few. On 6 June a low flying plane got into four miles before being detected, and dropped one small bomb, not close, after FADDLE dived and went deep.

7. Patrol boat activity was moderate. The Hunter-Killer group which searched for the FADDLE for 21 hours was exceptionally persistent and apparently on the "First team".

8. The FADDLE was exceptionally clean and shipshape upon her return from patrol. Her material condition is good. The FADDLE will be given a normal refit by the U.S.S. TROITERS during which period all defects will be corrected.

9. The health of the officers and crew is very good and the state of morale very high. One man was transferred at sea to another submarine returning to port five weeks before patrol ended because of a fungus infection of the skin which did not respond to the treatments available aboard ship. The loss of three fingers of the right hand by Lieutenant (junior grade) A. R. TROITERS, U.S. Navy in the painful accident which occurred on the night of 12 July while he was attempting to fire the Mk I signal projector, is regretted. The excellent manner in which Chief Hammacist's Mate G. J. ORBECK, U.S. Navy took care of this injury is praiseworthy. A separate report of the investigation of this accident is being submitted by the commanding officer.

Subject: U.S.S. PADDLE (SS263) - Report of Eighth War Patrol.
(15 May to 13 July 1945).

1. The eighth war patrol of the PADDLE, under the command of Lieutenant Commander J. P. Fitz-Patrick, U.S. Navy, was conducted in the Yellow Sea - East China Sea Area. The PADDLE, U.S.S. SEA DEFIL (SS400), and U.S.S. BOQUILL (SS396) formed a coordinated attack group with the commanding officer of the RONQUIL as group commander.

2. The PADDLE made numerous contacts with small craft and anti-submarine vessels during this aggressive, well conducted patrol. Four torpedo attacks were made on small ships which unfortunately were not successful. The excellency of the gunnery fire control party and gun crews was well demonstrated in three gun actions which accounted for the destruction of eight miscellaneous enemy small craft.

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

4. The Commander Submarine Force, Pacific Fleet, congratulates the commanding officer, officers and crew of the fighting ship PADDLE for this well conducted patrol and regrets that more worthwhile targets were not available. The Force Commander also congratulates the commanding officer, Lieutenant Commander Fitz-Patrick, upon the completion of his seventeenth war patrol which is believed to be a record number. The PADDLE is credited with having inflicted the following damage upon the enemy during this patrol:

| 2 - MIS (Motor Driven Picket Boats) | 50 tons each) (EC) | 100 tons (Gun Attack No. 1) |
