At 0409 hours however the Officer of the Watch reported an aircraft attacking from the Starboard beam. The aircraft fired rockets but fortunately Shakespeare was not hit. The attack on the U-boat was now off course out of the question.

Later the same day HMS Shakespeare ended her 7th war patrol (4th in the Mediterranean) at Algiers. (6)

(All times are zone -1)
0303 hours - In position 39°01'N, 12°40'E a darkened object was sighted abaft the Starboard beam. The Officer of the Watch quite rightly turned stern on until the object had been identified.

0310 hours - Fired three torpedoes from 6000 yards. No hits were obtained as the speed was under-estimated.

The attack was unobserved and the torpedoes must have missed from a wide margin. (6)

The other submarine was Benedetto Brin. The two Italian submarines had sailed from Naples to attack the Salerno landings. The loss of Velella was tragic, she was the last Italian submarine to be lost by enemy action as in a few hours Italian submarines would be ordered to surrender to Allied forces.

(All times are zone -2)
1953 hours - The Asdic operator reported HE. It was nearly dark. Sighed two submarines steering a course of 135°. They were about 1 nautical mile apart. Started attacking the one who would be against the remaining light in the Western sky the longest. The other was soon lost against the land.

2003 hours - Fired a full salvo of 6 torpedoes from what was thought to be 1200 yards but was more like 800 yards in hindsight. No less than 4 hits were observed and the enemy submarine disintegrated. The other submarine was heard to continue its passage Southbound but at a higher speed.

2015 hours - Another submarine was heard going south but it was never sighted.

2114 hours - Surfaced to withdraw from the scene to report the 2 southbound submarines. (6)

8 Sep 1943
Off Licosa Point, at 1345 hours, HMS Shakespeare (Lt. M.F.R. Ainslie, DSC, RN) sighted a northbound Italian submarine but was prevented from attack as she was near her beacon position and did not want to compromise it. This was most probably Alagi returning to base because of defects. The British submarine remained on the bottom until 2135 hours when she surfaced and successfully contacted her escort, the US destroyer USS Cole and commenced her beacon duties. At 2340 hours, she transferred her beach pilots to USS PC-624. Around 0030/09 the beacon duties were completed and HMS Shakespeare set course for Algiers escorted by USS Cole until 12°00'E (6)

HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) sank four Japanese sailing vessels with gunfire of the west coast of Siam.

(all times are zone -6,5)
1256 hours - During investigation of the Butang Group of islands sighted a junk and surfaced. Ordered the crew to their small boat. Opened the range to 1500 yards and sank the junk (20 tons, no cargo) with 9 rounds of gunfire.

During this action a second junk was sighted to the eastward. Closed this junk. The junk was slightly smaller, estimated at 15 tons and was carrying a cargo of rubber. Took the crew on board and sank the junk with demolition charges. Set course to investigate Pulo Tenga.

While closing the islands sighted the sails of two more junks to the northward. Both junks were estimated to be 20 tons. One was empty and the other contained bicycles, one motor bicycle and some machinery. Both crews were taken on board before their junks were sunk. Also a small boat of one of the junks was taken on board to assist in the landing of the unwanted members of the junks crews.

In the evening all crewmembers of the junks (minus one) were landed at Pulo Mulon. Thrasher now proceeded northwards (20)

27 Jan 1945 (position 8.56, 98.13)
HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) sank three Japanese sailing vessels with gunfire of the west coast of Siam in position 08°56'N, 98°13'E.

(all times are zone -6,5)

1400 hours - In position 08°56'N, 98°13'E sighted three junks of about 60 tons each, northbound and close inshore a few miles south of Koh Gah.

1445 hours - Fired two warning shots which had the desired effect and the crews abandoned their ships very smartly. Fire was opened from 3000 yards as a closer range was not possible due to the shallow water. Two of the junks were sunk by gunfire sat this range. It is therefore unknown what their cargos consisted of. The third junk on being abandoned swung round and sailed towards deeper water. It was therefore possible to board her. The junk was found to carry a cargo of soap and nuts. The junk was sunk with demolition charges. Thrasher now continued southward. (20)

28 Jan 1945 (position 7.06, 99.31)

1200 hours - In position 07°06'N, 99°31'E the sails of a junk were sighted. While closing this junk a motor driven junk was sighted approaching the first one from the south-east. A third junk was being towed by this motor-junk. Continued to close and opened fire from 4000 yards. The motor driven junk quickly slipped its tow and departed the scene at its best speed. Despite several near misses this junk managed to escape. This was also because the gun jammed several times due to faulty ammunition. Both other junks (of 40 tons each) were sunk by gunfire.

1500 hours - Closed a southbound junk of 20 tons. The crew was taken on board and the junk, that was loaded with rice, was sunk by demolition charges. The crew was later put on board a fishing vessel with the exception of one Chinese.
