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. (7)

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. (7)

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 (7)

Also taking passage in the convoy were the submarines HMS Trident (Lt. A.J.W. Pitt, DSO, RN), HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) and HMS Sea Scout (Lt. J.W. Kelly, RN) as well as 9 LCT's which were towed by some of the merchant vessels; These 9 LCT's were the following; HM LCT 480 (T/S.Lt. G.R. Sample, RNVR) which was being towed by the City of Lyons, HM LCT 488 (T/S.Lt. A.P.P. Thomas, RNVR) and HM LCT 489 (?) which were being towed by the Samfoyle, HM LCT 491 (T/Lt. W.C. Gray, RNVR) and HM LCT 7015 (T/S.Lt. D.H. Condick, RNVR) which were being towed by the Fort Finlay, HM LCT 494 (T/Lt. J. DSC, Murts, RNVR) and HM LCT 7014 (T/A/S.Lt. J.

The convoy was escorted by and the sloop HMS Fowey (A/Lt.Cdr. G.E. Newey, RNR) and the corvettes HMS Allington Castle (A/Lt.Cdr. P.A. Read, RNR) and HMS Knaresborough Castle (T/A/Lt.Cdr. J.F. Marchant, RNR).

The convoy encountered poor weather and by the 17th it had even worsened. Some of the landing craft were now suffering from the weather conditions. Due to the extreme weather conditions the convoy hove to A.M. on the 18th and additional escorts were requisted.

Late in the afternoon of the 18th, HM 480 had to be abandoned by her crew due to the damage she had sustained and water she had shipped from the weather, loose cargo and defective welds. The crew was picked up from Carley floats around 2200A/18 by HMS Allington Castle. She sank to the south of Ireland around 2330A/18 after having been scuttled with gunfire.

HM 488 had sustained damage during the night of the 17th/18th. Around 1000A/18, she slipped her tow and got underway under her own power to try to make for Milford Haven. More and more water entered the landing craft and when a pump failed it became apparent that she most likely would go down. HMS Knaresborough Castle then closed and it was attempted to abandon the landing craft. Some of the crew was taken off but ten men remained on board during the night of 18/19 and tried to keep the ship afloat. By 0415A/19 the ship had to be abandoned as it was about to sink. Red flares were fired and HMS Knaresborough Castle closed. While doing so the landing craft sank and only one of the ten men on board could be picked up. The other nine, including the landing craft's Commanding Officer drowned.

HM LCT 491 got into trouble during the early afternoon of the 18th and as a result she slipped her tow as did HM LCT 7015. By mid afternoon of the 18th she had shipped a very heavy sea which damaged the welding around the door in the bow. More big seas followed and the ship was shipping a lot of water. Around 0100A/19, HMS Allington Castle closed. Around 0330A/19, HM LCT 491 started to sink. HMS Allington Castle went alongside and managed to take off the entire crew.

HM LCT 494 parted her tow around 0845A/18. She was last seen during the afternoon of that day while under her own power. She must have sunk in the evening with the loss of the entire crew.

22 Jan 1945
HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) sank four sailing vessels with gunfire of the west coast of Siam.

1256FG/22 - 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 (24)

23 Jan 1945 (position 0.00, 0.00)
At 1314FG/23, HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) sighed a junk to the eastward of Koh Ngai in approximate position 07°25'N, 99°15'E. The junk was then taken under fire from long range. 30 rounds were expended in this 'long range gunnery practice'. The crew abandoned the junk but the result of the gunnery action was difficult to observe from long range. When the action was broken off the junk was seen to be still afloat. (31)

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

0555FG/27 - Dived in position 09°10'N, 98°06'E and proceeded southwards.

1248FG/27 - Surfaced and commenced a surface sweep along the coast.

1400FG/27 - 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.

1445FG/27 - 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 cargoes 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. (24)

28 Jan 1945 (position 7.06, 99.31)
HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) sank Japanese sailing vessels with gunfire and demolition charges of the west coast of Siam in position 07°06'N, 99°31'E.

1200FG/28 - 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.

1500FG/28 - 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.

1600FG/28 - Set course towards Trincomalee. (24)

1745FG/18, in position 06°21'N, 99°24'E sighted a junk of 20 tons. The crew was taken on board and later put on a fishing vessel. The cargo of the junk was rice, one sack of which was also put on board the fishing vessel. The junk was then sunk with gunfire. (24)

19 Mar 1945 (position 6.06, 100.13)
HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) sank three sailing vessels with gunfire to the south-east of Langkawi.

1350FG/19, Sighted a southbound motor driven two masted schooner of about 50 tons. Fired a warning shot and the schooner immediately heave to and the crew of 6 abandoned ship in their small boat. The vessel had a full cargo of mainly rice. The schooner was sunk by demolition charges. It started to rain heavily just as a junk was sighted to the North. Position was approximately 06°07'N, 100°00'E.

1530FG/19, The rain cleared and the junk was in sight. Fired a warning shot. The crew promptly abandoned ship in their small boat. The junk was sunk by gunfire.

1600FG/19, When about to open fire on a fully laden northbound junk of about 30 tons a Japanese aircraft broke through the clouds to the seaward. Dived. The aircraft most likely did not see the submarine as it was soon out of sight. Surfaced and sank the junk with gunfire. Position was 06°06'N, 100°13'E. Set course to the south of Penang. (24)

At 0526FG/22, Thrasher dived to the west of the Similan Islands in position 04°03.5'N, 100°11'E. The morning was spent carrying out reconnaissance of the area. Many small junks and sampans were observed to the eastward. All were thought to be fishing vessels and none were thought to be bigger then 10 tons.

During the afternoon Thrasher closed the islands and eventually passed between Rumbia and Lalang Island.

Shortly after 1800FG/22, Thrasher surfaced. This was earlier then intended as a storm was approaching. Two canoes were then launched which each made two trips to Lalang Island where four men were picked up and taken back to the submarine. The operation was completed in 49 minutes. Thrasher then vacated the area and subsequently set course to return to Trincomalee. (24)

18 Apr 1945
HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) begins her special operation, 'Operation Defraud'. A party was to be landed for a reconnaissance of Kamorta Island (Nicobar Islands). Following their reconnaissance they were to be picked up again.

At dawn on the 18th, Thrasher dived close northward of Katchall Island and proceeded eastwards towards Camorta Island arriving off the entrance to Expedition Harbour around 1100FG/18. Course was then altered to the north keeping approximately 1.5 miles from the shore. Later Thrasher turned to the south again. The reconnaissance was completed around 1600FG/18. Course was then altered to retire to seaward.

1930FG/18, Thrasher surfaced seven miles to the west of Camorta Island and commenced charging the battery.

2310FG/18, The boats were now on deck and Thrasher trimmed down, launched and took the boats in tow.

2335FG/18, Thrasher dived four miles west of the landing beach and proceeded inshore with the boats in tow. The sea was glassy calm and there was no wind and no swell.

0035FG/19, The boats were observed to slip their tow lines approximately eight cables from the shore. Thrasher then turned and proceeded to seaward.

[No log is available for this period so unfortunately no map can be displayed.] (24)

1 May 1945
HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) carries out special operation 'Ballast'. In operation 'Ballast' a party of six was landed at Parker Island in the Mergui Archipaligo.

At dawn on 30 April 1945, Thrasher dived to the west of the northern end of Bentinck Island. This was approximately 20 nautical miles from Parker Island. It was intended to arrive off the landing position about one hour before sunset and so reducing the time in the area before surfacing to a minimum, while still allowing ample time for a reconnaissance. Unfortunately, however, the spring tide had been badly underestimated and Parker Island was reached before mid-day. A most uncomfortable afternoon was then spent to the north of the Pickwick Group in a tide running at 3 to 3.5 knots.

At 1847FG/30, Thrasher surfaced. The sea was almost flat calm. There was a light westerly breeze resulting in no swell. It was completely overcast, dark clouds and rain in the offing. It was decided to anchor between Parker and Amie Islands. This was needed as it soon started to rain heavily and it would have been impossible to maintain position in the tideway.

At 2020FG/30, Thrasher dropped anchor in six fathoms and commenced getting the boats and stores on deck. Thrasher subsequently trimmed down and launched the boats. On completion of storing each boat they lay off on the end of a line awaiting the last boat.

At 2205FG/30, the last boat was ready and Thrasher weighed anchor. The intended landing position was in the large bay on the north-west side of the island. The entrance to this bay was one mile from the intended launching position. Owing to the distance involved it was decided that the submarine would accompany the boats as far as possible, partly to show them the way and also to be at hand if something would go wrong.

Unfortunately, all boats started up their engines and slipped before the anchor was weighed. It was very soon apparent that the motor canoes were not powerful enough and to make matters even worse their engines failed within a few minutes. By the time the anchor was up all five boats were almost out of sight and still going strong, but in the wrong direction. Eventually, after a quick chase, all boats were rounded up and taken in tow towards a position as close to the landing beach as possible. On reaching that position it was found that the engine of one boat could not be repaired and it had to be towed to the shore by the others.

At 0016FG/1, the party signalled having arrived on the beach safely though some boats had to use their paddles instead of engines. The landing had been completed just in time as it now began to rain in earnest. Thrasher then commenced to retire from the area. (24)

5 May 1945
Around 0745FG/5, HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) ended her 20th war patrol at Trincomalee. On entering harbour D/G and noise trials were carried out. (24)

0925FG/27 - Surfaced and sank the vessel with gunfire. Range was 3500 yards. 35 rounds were used for 5 hits. The crew of this coaster gives valuable information on shipping movements. Lt.Cdr. Ainslie decides to patrol further inshore.

1030FG/27 - Surfaced to sink another coaster. This one looks like the first one but larger than the first one, 80 to 100 feet in length. A warning shot caused the crew to abandon ship. Fire was then continued from 3200 yards. 38 rounds were fired for 6 hits.

1225FG/27 - Yet another coaster came in sight. Soon afterwards followed by a second and later a third. All vessels looked like the second coaster sunk this day. All three vessels were proceeding as close inshore as possible at two mile intervals. It was decided to surface as the second one had passed. Then fired warning shots at the first and third coaster hoping that their crews would abandon them. In this way it was possible to deal with at least two of them and possibly all three.

1315FG/27 - Surfaced and fired the warning shots. The second and third ships stopped at once but the first one that was at extreme range unfortunately was able to escape. The second vessel was sunk when the crew was clear. Range 4400 yards, 21 rounds. The third coaster was sunk from 5300 yards with 28 rounds. Dived and retreated to deeper water but remained in the vicinity.

1605FG/27 - Sighted a vessel approaching from the North which was later found out to be a motor schooner.

1635FG/27 - Surfaced and closed this vessel which was in deep water. The crew of nine were taken on board. Their small boat was filled with unwanted prisoners whose interrogation was complete. The schooner was 60 feet in length, and was powered by a two cylinder engine. It was sunk with gunfire.
