Air cover departed after giving him a position and permission to depart. Reported no contacts, and all planes out. Raining in torrents, and seas are mountainous; decided to remain on surface and patrol south of lifeguard station. Had intended to close beach off of SHIOHO ISLAND for submerged patrol but low visibility and heavy seas preclude maintenance of periscope watch subcargoes.

1115
Sighted FBLY bearing 180°T, range 10 miles, on northerly course. Exchanged calls by radio, and identified him as I.O JI.2.1.

(C) NAVY
The weather from Pearl to Saipan and from Saipan to the area was clear and calm.
From the time of entering the area, the skies were overcast practically all the time. Average force of the wind was about 3, and the sea averaged about force 2-3. There were a few calm clear days south of thirty-two degrees north, but they were a rare exception to the rule of overcast skies and choppy seas. I am usually were frequent. During the first eight days in the area, the wind and sea was from the east and north east, but thereafter they were variable, generally being from north west to south west. The weather changed very rapidly, being overcast and choppy one moment and clear and calm a very short time later. The wind was subject to very quick changes in force and directions.
The atmosphere was always heavy, particularly close to land.

(D) TIDAL TACTICAL UNIT
The currents close to the mainland, were, in one rail, as noted in the pilots and on the charts. On 20 July and the night of 20-21 July, in the KIAHO IADA, the current was observed to set 213° with a drift of 1 knot. On 22 July, in the same area, off KATOLIK SAII, the current set 290°; drift 0.6 knots.
As indicated on the Streamline current chart prepared by the PICT, weather Control, south of 32 degrees north and east of 135 degrees east the currents are variable and unpredictable. The set in this area varied from north west to south west with a drift of 0.5-1.0 knot. On rare occasions the current in this area was observed to set from north to east.

(E) NAVIGATIONAL AID.

Attack: Day submerged.

(T) 1: 1

No evidence of mine laying or mine sweeping was seen.
At 1337 on 20 June, exploded and sank one type 93, model unknown.
Japanese sea mine. Mine was fairly new, by appearance, exploded a brick red.
Used 50 cell, machine gun to sink it because of less probability of explosion
than with 20mm. Erected 40 rounds.
At 1605 on 29 June, sank one type 93, model one Japanese sea mine, of
now appearance and well preserved. Put numerous holes in mine with counter-
bined fire from 50 cell, and 20mm, machine guns before mine finally sank.
At 1735 on 29 June, sank and exploded another type 93, model one mine.
Fire from 20mm, started mine to smoke, and it was soon that small land hole
plate on top of mine was missing. Several holes were put in case by 20mm.
Fire, but mine was finally exploded by third hit by rounding automatic rifle.
This mine was covered with barricades and was much older in appearance than
mine sank previously that c.afternoon.
At 1058 on 2 July, sank one type 93, model one Japanese sea mine. Put
numerous holes in it with combined fire from cartridge, 1, and 50 cell.
Machine guns, before it sank.

2002 on 2 July, exploded and sank another type 93, model one mine. This was new in appearance. 50 cell, machine gun fire, after several hits, caused the mine to commence smoke. Smoke increased in intensity for a period of about two minutes, and then mine exploded with a low order explosion, blowing complete top half inch into the air.

It 1148 on 3 July, sank a mark 6, model one Japanese sea mine. This mine was covered with a heavy coat of barnacles, and was scuttled. Several hits from 50 cell. machine gun fire triggered cras., and mine sank.

It 1350 on 3 July, exploded a type 93, model one mine, new in appearance and well preserved, with ten rounds from Browning automatic. This explosion was closest yet came in effect, causing quite a jar and to round pieces of mine case all over, some landing on deck.

It 0815, 4 July sank a type 93, model one mine, new in appearance, with fire from but and 50 cell. machine gun, puncturing case, and causing mine to smoke. No explosion.

It 0720, 5 July sank a type 93, model one mine with fire from 50 cell. machine gun, causing it to smoke and subsequent sink. No explosion.

It 0745, 5 July sank another type 93, model one mine with fire from 50 cell. machine gun, puncturing case.

It 0914, 5 July sank another type 93, model one mine with fire from 50 cell. machine gun, puncturing case, and causing mine to smoke. No explosion.

Very noisy

intermittent noise.

The noise in the port shaft varies from slight to very pronounced, with the roll of the ship. It is believed that the noise is caused by the use of the cylinder liner, No. 2 main engine; - During the early part of the patrol, No. 1 cylinder liner devolved a small crack in the water jacket adjacent to the water junction connection. The engine was kept in commission the remainder of patrol, operated only when using four engines.

(c) No. 2 I.C. motor generator: - This motor generator will not carry more than approximately 35% of its rated load. No reason for this can be advanced.

2. Construction and Repair: - No major defects were experienced with the execution of excessive leakage around both periscope, which failed to respond to any and all treatment.

Upon entry into Pearl for refit, Carlock became aware as used on both periscopes. A new type 4.1 periscope was installed in the No. 1 position, and neoprene reshelled.

During training period both periscopes lacked excessively, and neoprene packing was removed and flex installed prior to departure for patrol. Throughout the patrol it all details periscope lacked excessively and were extremely hard to train. No. 1 periscope was causing the most inconvenience. Prior to our last refit period both periscope, when packed with the Carlock neoprene, were easy to turn and light. No. 1 periscope was causing the most inconvenience.

1. U.S.S. SILVERFILES (SS236) - I report of Portsmouth war Patrol.

Transmissions: Transmissions on ship-shore frequencies were made with good results considering the interference and the amount of traffic.

On July after initial call up to PIF on 8470 loss, we were told to wait. W/ay was 30 minutes. Signal strength was 3-2 to 5-3 with interference at times 5-5 taking communication difficult.

On 29 June our first call up to PIF was made at 10022. We were told to wait until he had received an urgent. Meanwhile PIF evidently finished the urgent as he accepted another message with our star reccomence. Go ahead was received at 11402, and the order at 11473. Delay was 1 3/4 hours. Signal strength 3-2 to 5-3 again with considerable interference. During this period it was necessary to secure watch on lifeguard circuit.

The first time the TEL-5 refused to double during initial call up to PIF, PIF allowed raters by giving a go-ahead.

Material failures: The TEL-5 refused to double in the first H.F. cap. Tunnels occurred three times. Tunnels was perfect but transmission was on 1235 loss. Instead of 8470 loss. This was one factor of major transmission troubles last patrol and the resultant leak of deliverability resulted in effective use of IRPL-10.

Between Pearl and Saipan the TEL-5 gave very poor reception. Saipan check showed poor frequency band switch re-encryption control and low sensitivity. The receiver was exchanged.

(2) RADAR

The SJ-1 was operated at night and during very cold of low visibility. To prevent possible detection it was keyed at two minute intervals. For-formance was excellent throughout the patrol, and except for minor tube failures and on infrequent vertical jitter if the cross trace were no defects.

The ST radar was not used except to obtain ranges on land while sun-argued. Operation was satisfactory.

A tentatively surprise was the over-ance of the SD and damaged by the addition of the SD-5 receiver and indicator. The SD was keyed at one and two minute intervals during daylight and at night when IFT or deviance air-brake radars were intercepted by the H.F. radios were obtained on 1-29s out to forty and fifty miles.

(3) SOUND GEAR AND SOUND CONDITIONS

The TDI was rammed continuously on the surface. The equipment held up well with only minor defects, easily repaired. No contacts were made on this instrument. As the major portion of the patrol was on the surface, little use was made of the QO-JK or the JP and little opportunity was had to note sound condition.

* Once transcribed, this report is no longer subject to further transfer to hospital.

The performance of duty of all hands, in a patrol so lacking of contacts, was excellent. New men proved generally satisfactory. Regular instruction periods were held for non-qualified personnel, and all new men made considerable progress toward qualification. The personnel situation with one or two exceptions is generally good, and most men tactically scheduled for transfer at the conclusion of the patrol can be replaced from the lower ratings on board.

(U)  HIDDEN AND RADIO COUNTER ERRORS:

The LAF was equipped with directional LBI antennas during last refit. Sensitivity was much lower with these than with the old stub antennas. They worked as well as could be expected on high signal strength interference, but the intercept system leaves much to be desired. Switching the ship is a clumsy and ineffective way of determining direction. A power transformer burned out in the LAF-5 and this, speaker provided was lacking on waiting. A jury rig put the equipment in operation again but the sensitivity was disappointing.

The following interceptions were made on the LAF:

Communication Countermeasure

I. Jamming - 1. No jamming was encountered on any S/M/RFO frequency.
2. The usual filterable G/T was encountered on ship-snore frequencies. Of note was interference caused by stations M/F and N/M.
3. TORACO frequencies all had continuous jamming with the exception of a short period after shifting frequency. Consisted of 2 jamming with some occasional of the bag pipe variety. Jamming was fairly effective but could be filtered and co-iod through if signal was not too weak.

— page 33 —
4. As the majority of transmission on 0475 kcs. was by voice, jamming was most effective on this circuit. Circuit operated to be monitored, as on WOPICO, by a look-in receiver as jamming was negligible during the day and strong at night. There were three types; at 2811322 June, weak ineffective but wipc transmission was heard. At night voice jamming was at red pressure the same words or expressions, which partially looked the circuit but was more of a nuisance value to an effective jamming. GW was used almost continuously at night blocking out or badly distorting weak signals, at note were MDI calling MDI, with USS and USS sending nothing but 's and their calls.

5. 3310 and 7915 had frequent CW jamming which could be filtered and which would not have been very effective if the signals were not so weak.

6. The HMS receiver does not have adequate filter units.

II. Location: From 0622 to 0701 on 28 June. 20 second classes were covered by hard on 500 kcs. A were unable to obtain a bearing. No call was sent. There was an accurate frequency setting, the note was serial, and signal was S-5. Collected to be an emulation of distress signal.

5. Very windy in this area made determination of probable position three days later subject to large error.

4. A better system for locating in this air cover is needed. Our copying of messages and FOK schedules was interrupted frequently over a period of several hours while trying to home in our cover.

5. Especially during carrier strikes there is a need for a clearing house to check over and verify reports of downed planes. On one day we made two "side" trips of about 20 miles from or station at full speed on four main carriers to reach a reported position of a downed pilot, only to find after getting there that instead of 40 miles bearing 180 from a reference point, the correct position was 180 miles bearing 040 from that point in one case, and in the other case, it was 25 miles bearing 180 from a point other than the one first used in the message. If possible, obititing planes should be asked to verify position by shackled position to an information center, and then have this center notify the closest submarine.

5. The method presently in use in establishing identification is good, except for night raids by alert 29s when returning to base, and assist in directly overhead. Unless it is possible to establish contact with each one on the, it is impossible to determine that they are friendly. If each plane would contact each submarine as they approach them, it would cause our minds a bit, at least.

7. If required league duty, when picking up or searching for downed pilots, is interesting duty. I rate of the crew brightened considerably when we started out after our first pilot, and it was a pleasure to pick up our trio, my new crew aboard for our start trip back to Guam. But the days spent out in the middle of the area with no calls for service were long and "decadent". It is recommended that insofar as practicable boats be rotated between the "close-in", and the "far out" stations to avoid a lowering of morale, and to give all boats a possible chance for contacts along the coast at the Empire, and possibly to see the raids in progress.

To: The Commander in Chief, U.S. S.T.T. F.I.T.
Via: (1) The Commander Submarine Force, 2nd Submarine Fleet, (2) The Commander in Chief, U.S. S.T.T. F.I.T.
Subj. ect: U.S. Submarine Force, 2nd Submarine Fleet.

1. The lieutenant was still on the ship when the command of the submarine was given. The submarine was sunk on 24 July 1945.

2. The lieutenant was relieved of his command on 22 July 1945 and Lieutenant S. V. Surtchi, U.S. Navy from the U.S.S. S.T.T. D.T. on 24 July 1945.

3. Only one enemy plane and one enemy submarine were contacted. The morning of 14 July a periscope was seen on an armed steamer. The submarine, which was 40 tons, was two 14-2 torpedoes from the stern tubes, depth set at 12 feet. The depth of the torpedoes were listed as 12 feet. The torpedoes were 12 feet long and 9 feet wide. The submarine was 12 feet long and

: 2. This report will be destroyed prior to entering patrol area.

CONFIDENTIAL:
TERM OF DURATION: 30 May to 30 July 1945.
SUBJECT: The fourteenth war patrol of the SILVER SIDES, under the command of Commander J. C. Nichols, U.S. Navy, was devoted to lifeguard duty in waters south of Shikoku and Honshu.

3. Late in this patrol, the navy long days spent by the SILVER SIDES in thoroughly covering her lifeguard area in the face of adverse weather conditions, was rewarded with the opportunity of rescuing - first, a U.S. Army fighter pilot, and two days later, a Navy fighter pilot. The SILVER SIDES had one contact with a shipping during this patrol, a small armed steam trawler which was attacked by torpedoes without success.

4. Awa i of Submarine Combat Insignia for this patrol is authorized.

5. The Commander Submarine Force, Pacific Fleet, congratulates the commander's officer, officers, and crew of the SILVER SIDES for adding another successful patrol to the long illustrious record of this fighting ship.
