HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) torpedoed and sank the Italian passenger ship Dalmatia L. (3352 GRT, built 1903) south-west of Capo dell'Armi in position 37°45'N, 15°30'E. Dalmatia L. was escorted by the torpedo boat Giuseppe Sirtori.

Dalmatia L. was hit in the forward section and was abandoned by her crew but she did not sink immediately. Sirtori was joined by the torpedo boat Giuseppe Cesare Abba which had observed the torpedoing from a distance. Depth charges were dropped and then efforts were made to take the stricken vessel in tow. The tug Titano arrived to take in charge of the towing and part of the crew of Dalmatia L. returned aboard their ship but at 0140/26 she finally broke in two and foundered.

Escort was provided by the destroyers Ugolino Vivaldi, Lanzerotto Malocello, Nicolo Zeno, Maestrale, Strale and Premuda, and the torpedo boats Pallade and Calliope. The torpedoes were spotted by an escorting aircraft which machine-gunned them to give the alarm and the convoy altered course to avoid them. Unione was missed ahead and astern by two torpedoes. The destroyer Vivaldi depth charged the submarine.

(All times are zone -1)
1125 hours - Sighted two merchant vessels and three destroyers bearing 040°. Enemy course was 250°. Started attack.

HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) ended her 9th war patrol (8th in the Mediterranean) at Malta. (3)

6 Apr 1942
HMS P 34 (Lt. J.W.D. Coombe, RN) departed Malta for her 10th war patrol (9th in the Mediterranean). She was ordered to patrol near Capo Santa Maria di Leuca to operate against traffic from Taranto to the Adriatic.

Lt. Coombe had taken command vice Lt. Harrison for this patrol in order to give Lt. Harrison a rest.

For the daily positions of HMS P 34 during this patrol see the map below.

(3)

7 Apr 1942
HMS P 34 (Lt. J.W.D. Coombe, RN) is ordered to proceed to position 37°00'N, 16°14'E to intercept a southbound enemy merchant vessel. (3)

8 Apr 1942
HMS P 34 (Lt. J.W.D. Coombe, RN) is ordered to proceed to her original patrol area. (3)

12 Apr 1942
At 0924 hours (zone -1) HMS P 34 (Lt. J.W.D. Coombe, RN) was shaken by a violent explosion while in position 39°45'N, 18°29'5"E. The submarine was blown to the surface. The fore hatch lifted and admitted a quantity of water. All lights in the after part of the ship were extinguished. Three depth gauges in the control room were put out of action and considerable other damage was done. P 34 had a lucky escape after hitting a mine. This was most likely a mine laid by the minelayer Barletta in June 1940 (minefield 4 AS).

P 34 altered course to get clear of the coast to make good defects and to establish if she could remain on patrol. In the afternoon most damage had been repaired and it was decided to remain on patrol. P 34 had meanwhile received a signal to take up a patrol position in the Ionian Sea. (3)

13 Apr 1942
As it was likely that enemy 'heavy units' might be met Lt. Coombe decided that the depth settings of the torpedoes were to be altered. It was then found out that due to the explosion of the previous day the torpedoes could not be retracted from the tubes nor that they could be fired. The defects could not be repaired at sea so Lt. Coombe had no other choice than to abandon the patrol and HMS P 34 set course back to Malta. (3)

16 Apr 1942
HMS P 34 (Lt. J.W.D. Coombe, RN) ended her 10th war patrol (9th in the Mediterranean) at Malta. (3)

29 Apr 1942
HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) departed Malta for Alexandria. Due to heavy enemy air attacks it had been decided to retire the small number of submarines currently based at Malta to Alexandria.

For the daily and attack positions of HMS P 34 during this patrol see the map below.

(4)

15 Jun 1942
At 0615 hours (zone -3) HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) spotted the Italian battlefleet. An air attack was in progress and the ships were maneuvering all over the place. P 34 was unable to obtain a favourable firing position.

At 1012 hours, while approaching a damaged Trento-class cruiser this ship was seen to sink as a result of torpedo hits by HMS P 35 (Lt. S.L.C. Maydon, RN). P 35 had gone deep to evade but Lt. Harrison sat front row and was able to confirm that the cruiser had sunk. [This was indeed Trento.] (4)

24 Jun 1942
HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) makes a torpedo attack on German U-boat U-77 south of Crete in position 34°20'N, 24°09'E. All torpedoes fired however missed their target.

It was however thought that the target had been sunk but this was not the case.

(All times are zone -3)
0735 hours - Heard HE bearing 045°.

0740 hours - Sighted a German U-boat bearing 060° at long range. Enemy course was 140°, speed 10 knots by Asdic. Started attack.

0800 hours - In position 34°20'N, 24°09'E fired four torpedoes from 7000 yards.

0807 hours - Heard a loud explosion. HE of the target stopped immediately. Nearly two minutes later a second loud explosion was heard. This was thought to be a internal explosion on board the U-boat. It is thought the U-boat had been hit and sunk. (4)

27 Jun 1942
At 1500 hours (zone -3), in approximate position 32°31'N, 28°32'E, HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) sighted a German u-boat at a range of 9000 yards. P 34 closed submerged at high speed but the u-boat dived before a favourable attack position could be obtained.

However, there were no U-boat in this area (U-372 and U-453 were more than 60 miles to the south). This may have been HMS P 31 (Lt. J.B.de B. Kershaw, RN) also returning to Alexandria. (4)

Passage of the Straits of Gibraltar and organization of escort forces.

The convoy then passed the Straits of Gibraltar during the night of 9/10 August 1942 in dense fog but despite this the convoy was detected by German and Italian spies and reported.

After passing the Straits of Gibraltar the convoy was organized as follows;
The actual convoy was protected a large force of warships until the whole force would split up before entering the Sicilian narrows after which ‘Force X’ under command of Rear-Admiral Sir H.M. Burrough, CB, DSO, RN was to accompany the convoy to the approaches to Malta where they would be met by the Malta Minesweeping Flotilla, which was then to sweep the convoy into the harbour. Force X was made up of the following ships:
Licht cruisers: HMS Nigeria (flagship), HMS Kenya,, HMS Manchester.

Sinclair), HMS Wishart and HMS Vansittart. Escort destroyer: HMS Zetland. Also attached were the aircraft carrier HMS Furious (for Operation Bellows, the launching of Hurricane fighters for Malta. HMS Furious only carried four Albacore aircraft for A/S searches after the Hurricanes had been launched) and the ‘spare’ destroyers HMS Keppel (Cdr. J.E. Broome, RN), HMS Malcolm, HMS Venomous, HMS Vidette (Lt.Cdr. E.N. Walmsley, DSC, RN), HMS Westcott, HMS Wolverine, HMS Wrestler and HMS Amazon. These ‘spare’ destroyers were to take the place of destroyers in the screen ‘Force Z’ if needed, escort HMS Furious during her return passage to Gibraltar after she had completed Operation Bellows and / or strengthen the escort of ‘Force R’.

Then there was also ‘Force R’, the fuelling force. This force was made up of the following ships:
Corvettes: HMS Jonquil (Lt.Cdr. R.E.H. Partington, RD, RNR), HMS Spiraea (Lt.Cdr. R.S. Miller, DSC, RNR), HMS Geranium (T/Lt. A. Foxall, RNR) and HMS Coltsfoot (T/Lt. the Hon. W.K. Rous, RNVR).
Rescue tug: HMS Salvonia.
RFA tankers: RFA Brown Ranger (3417 GRT, built 1941, Master D.B.C. Ralph) and RFA Dingledale (8145 GRT, built 1941, Master R.T. Duthie).

Before we give an account of the passage of the main convoy we will now first describe the operations taking place in the Eastern Mediterranean (Operations MG 3 and MG 4), the launching of the Hurricane fighters for Malta by HMS Furious (Operation Bellows) and the return convoy from Malta (Operation Ascendant) as well as on submarine operations / dispositions.

Diversion in the Eastern Mediterranean.

As part of the plan for Operation Pedestal the Mediterranean Fleet had to carry out a diversion in the Eastern part of the Mediterranean. Before we go to the operations in the Western Mediterranean we will first give an account of the events in the Eastern Mediterranean.

It was at this time not possible to sent any supplies from Egypt to Malta as all supplies and forces were much needed for the upcoming land battle at El Alamein it was agreed that ‘a dummy convoy’ would be sent towards Malta with the object of preventing the enemy to direct the full weight of their air and naval power towards the Western Mediterranean.

In the evening of 10 August 1942 a ‘convoy’ (MG 3) of three merchant ships departed Port Said escorted by three cruisers and ten destroyers. Next morning one more merchant ship departed Haifa escorted by two cruisers and five destroyers. The two forces joined that day (the 11th) and then turned back dispersing during the night. The Italian fleet however did not go to sea to attack ‘the bait’.

The forces taking part in this operation were:
From Port Said:
Merchant vessels City of Edinburgh (8036 GRT, built 1938), City of Lincoln (8039 GRT, built 1938) and City of Pretoria (8049 GRT, built 1937) escorted by the light cruisers HMS Arethusa (Capt. A.C. Chapman, RN, flying the flag of Rear-Admiral I.G. Glennie, RN), HMS Euryalus (Capt. E.W. Bush, DSO, DSC, RN), the AA cruiser HMS Coventry (Capt. R.J.R. Dendy, RN) and the destroyers HMS Jervis (Capt. A.L. Poland, DSO and Bar, DSC, RN), HMS Kelvin (Cdr. M.S. Townsend, OBE, DSC and Bar, RN), HMS Pakenham (Capt. E.B.K. Stevens, DSO, DSC, RN), HMS Paladin (Cdr. A.F. Pugsley, RN) and the escort destroyers HMS Dulverton(Lt.Cdr. W.N. Petch, OBE, RN), HMS Hurworth (Lt.Cdr. J.T.B. Birch, RN), HMS Eridge (Lt.Cdr. W.F.N. Gregory-Smith, DSC, RN), HMS Hursley (Lt. W.J.P. Church, DSC, RN), HMS Beaufort (Lt.Cdr. S.O’G Roche, RN) and HMS Belvoir (Lt. J.F.D. Bush, DSC and Bar, RN).

From Haifa:
Merchant vessel Ajax (7797 GRT, built 1931) escorted by the light cruisers HMS Cleopatra (Capt. G. Grantham, DSO, RN, flagship of Rear-Admiral P.L. Vian, KBE, DSO and 2 Bars, RN), HMS Dido (Capt. H.W.U. McCall, RN), the destroyers HMS Sikh (Capt. St.J. A. Micklethwait, DSO and Bar, RN), HMS Zulu (Cdr. R.T. White, DSO and Bar, RN), HMS Javelin (Cdr. G.E. Fardell, RN) and the escort destroyers HMS Tetcott (Lt. H.R. Rycroft, RN) and HMS Croome (Lt.Cdr. R.C. Egan, RN).

After dark on 11 August 1942 the force turned back and the City of Pretoria returned to Port Said escorted by HMS Eridge and HMS Hursley. The City of Edinburgh, escorted by HMS Beaufort and HMS Belvoir proceeded to Haifa. The City of Lincoln escorted by HMS Dulverton and HMS Hurworth proceeded to Beirut and finally the Ajax, escorted by HMS Tetcott and HMS Croome returned to Haifa. HMS Dido had to return to Port Said with hull defects. She was escorted by HMS Pakenham, HMS Paladin and HMS Jervis.

HMS Cleopatra, HMS Arethusa, HMS Sikh, HMS Zulu, HMS Javelin and HMS Kelvin then proceeded to carry out another diversion (Operation MG 4). They bombarded Rhodos harbour and the Alliotti Flour Mills during the night of 12/13 August but did little damage. On the way back HMS Javelin attacked a submarine contact in position 34°45’N, 31°04’E between 0654 and 0804 hours. She reported that there was no doubt that the submarine was sunk but no Axis submarines were operating in this area so the attack must have been bogus. This force returned to Haifa at 1900/13.

Operation Bellows.

During operation Bellows, the aircraft carrier HMS Furious, started 37 Spitfire which were to proceed to Malta, when south of the Balearic Islands. The Admiralty had decided to carry out this operation at the same time as Operation Pedestal.

HMS Furious remained with the convoy until 1200/11. She then launched the Spitfires for Malta in 5 batches between 1230 and 1515 hours. During these flying off operations she acted independently with the destroyers HMS Lookout and HMS Lightning. After having launched the last batch of Spitfires she briefly re-joined to convoy until around 1700 hours when she split off and set course for Gibraltar escorted by the destroyers HMS Malcolm, HMS Wolverine and HMS Wrestler. These were joined shortly afterwards by HMS Keppel and HMS Venomous.

Around 0100/12, HMS Wolverine, rammed and sank the Italian submarine Dagabur which was trying to attack HMS Furious. Around 0200 hours, HMS Wolverine reported that she was stopped due to the damage she had sustained in the ramming. HMS Malcolm was detached to assist her.

At 1530/12, the destroyer HMS Vidette joined the screen. The force then entered Gibraltar Bay around 1930/12. The damaged HMS Wolverine arrived at Gibraltar at 1230/13 followed by HMS Malcolm around 1530/13.

Operation Ascendant

On 10 August 1942 the empty transports Troilus (7648 GRT, built 1921) and Orari (10107 GRT, built 1931) departed Malta after dark for Gibraltar. They were escorted by the destroyer HMS Matchless (Lt.Cdr. J. Mowlam, RN) and the escort destroyer HMS Badsworth (Lt. G.T.S. Gray, DSC, RN). They first proceeded to the south of Lampedusa, then hugged the Tunisian coast as far as Galita Island. Near Cape Bon they encountered the Italian destroyer Lanzerotto Malocello that was laying a minefield. They had a brief gunfight but this was soon ended as both sides were thinking the enemy was Vichy-French. The remained of the passage to Gibraltar was uneventful and the convoy arrived at Gibraltar shortly before noon on 14 August 1942.

Submarine operations / dispositions.
Eight submarines took part in the operation; these were HMS Utmost (Lt. A.W. Langridge, RN), HMS P 31 (Lt. J.B.de B. Kershaw, DSO, RN), HMS P 34 (Lt. P.R.H. Harrison, DSC, RN), HMS P 42 (Lt. A.C.G. Mars, RN), HMS P 44 (Lt. T.E. Barlow, RN), HMS P 46 (Lt. J.S. Stevens, DSC, RN), HMS P 211 (Cdr. B. Bryant, DSC, RN), HMS P 222 (Lt.Cdr. A.J. MacKenzie, RN). Two of these were to carry out normal dived patrol to the north of Sicily, one off Palermo, the other off Milazzo which is futher to the east. The other six submarines were given alternative patrol lines south of Pantelleria, one od which they were to take up at dawn on 13 August 1942, according to the movements of enemy surface ships that might threathen the convoy from the westward. When the convoy had passed the patrol line, which it should have done by that time, the submarines were to proceed on the surface parallel to the convoy as a screen and to dive away clear of the convoy at noon. It was expressly intended that they should be seen on the surface and reported by enemy aircraft in order to deter enemy warships from attacking the convoy.

Enemy warships did go to sea but as soon as it was clear that the enemy ships could not reach the convoy the sunmarines were ordered to dive and retire. These six sumarines had no contact with the enemy. One of the the two submarines off the north coast of Sicily, HMS P 42, managed to torpedo two Italian cruisers near Stromboli on the morning of 13 August 1942.

Now we return to the main convoy to Malta.

Passage eastwards after passing the Straits of Gibraltar.

10 and 11 August 1942.

After passing through the Straits of Gibraltar in the early hours of 10 August 1942, in dense fog, the convoy was first sighted by an Italian passenger aircraft, which sighted the convoy in the afternoon of the same day. German reconnaissance aircraft started shadowing the convoy from dawn on the 11th, and thereafter they or Italian aircraft kept the convoy under continuous observation, despite the effort of the fighters from the carriers to shoot them down or drive them off. At 1315 hours, HMS Eagle, was hit an sunk by torpedoes from the German submarine U-73 which had penetrated the destroyer screen. At that moment there were thirteen destroyers in the screen, the remainder was away from the main convoy, escorting HMS Furious during the flying off operations of the Hurricane fighters for Malta or oiling from and screening ‘Force R’ which was several miles away. Between 1430/10 and and 2030/11 no less then three cruisers and twenty-four destroyers fuelled from the two oilers of ‘Force R’.

At the time of the torpedoing of HMS Eagle the convoy was in four columns, zigzagging at 13 knots, with the heavy ships stationed close round it and a destroyer screen ahead. HMS Eagle was on the starboard quarter of the convoy. She was hit on her starboard side by four torpedoes which had dived through the destroyer screen and the convoy columns undetected and then torpedoed and sank the Eagle in position 38°05’N, 03°02’E (Another source gives 03°12’E but this might be a typo). The carrier sank quickly in about 8 minutes, 926 of her crew, including the Commanding Officer, were rescued by the destroyers HMS Laforey and HMS Lookout and the rescue tug HMS Jaunty. At the time of her sinking, HMS Eagle had four aircraft on patrol. These landed on the other carriers. All other aircraft were lost with the ship. The survivors picked up were later transferred to the destroyers HMS Keppel, HMS Malcolm and HMS Venomous that were to escort HMS Furious back to Gibraltar. The tug HMS Jaunty that had been involved in picking up survivors was never able to rejoin the convoy due to her slow speed.

Late in the afternoon air attacks were expected so Vice-Admiral Syfret ordered the destroyer to form an all-round screen. Indeed the air attacks started around sunset, 2045 hours. The last destroyers had just returned from oiling from ‘Force R’. The enemy aircraft that were attacking were 36 German bombers and torpedo aircraft, Ju 88’s and He 111’s, most of which attacked the convoy but a few attacked ‘Force R’ to the southward. The Junkers arrived first, diving down from 8000 feet to 2000 / 3000 feet to drop their bombs. They claimed to have hit an aircraft carrier and one of the merchant ships. Then the Heinkels attacked, they claimed to have torpedoed a cruiser but during the attacks no ship was hit. The British fighter cover was unable to attack / find the enemy in the failing light. Four enemy aircraft were claimed shot down by the ships AA fire but it appears only two JU 88’s were in fact shot down.

12 August 1942

At 0915/12 another wave of German aircraft attacked the convoy. Some twenty or more JU 88’s approached the convoy out of the sun ahead. They were intercepted by fighters about 25 miles from the convoy. About a dozen got through to the convoy, making high-level or shallow dive-bombing attacks individually but without any result. Eight German aircraft were claimed to be shot down by the fighters and two more by AA guns from the ships. The fighters meanwhile were also busy dealng with shadowers, three of which are claimed to have been shot down before the morning attack. Around this time destroyers were also busy with numerous submarine contact which were attacked by depth charges.

Around noon the enemy launched heavy air attacks from the Sardinian airfields. Seventy aircraft approached which were heavily escorted by fighters. They attacked in stages and employed new methods.

First ten Italian torpedo-bombers were each to drop some sort of circling torpedo or mine a few hundred yards ahead of the British force, while eight fighter bombers made dive-bombing and machine-gun attacks. The object at this stage was clearly to dislocate the formation of the force and to draw anti-aircraft fire, making the ships more vulnerable to a torpedo attack which soon followed with over forty aircraft. They attacked in two groups, one on either bow of the convoy. The next stage was a shallow dive-bombing attack by German aircraft, after which two Italian Reggiane 2001 fighters, each with a single heavy armour-piercing bomb were to dive bomb on one of the aircraft carriers, whilst yet another new form of attack was to be employed against the other carrier, but defects in the weapon prevented this attack from taking place.

The enemy attack went according to plan besides that the torpedo attack was only made half an our after the ‘mines’ were dropped instead of five minutes. British fighters met the minelaying aircraft, they shot down one of them as they approached. The remaining nine aircraft dropped their ‘mines’ at 1215 hours in the path of the force, which turned to avoid the danger. The mines were heard to explode several minutes later. Only three of the fighter-bombers of this stage of the attack appear to have reached as far the screen, but HMS Lightning had a narrow escape from their bombs.

The torpedo-aircraft appeared at 1245 hours. Their number were brought down a bit due to British fighters. The remaining aircraft, estimated at 25 to 30 machines, attacked from the port bow, port beam and starboard quarter. They dropped their torpedoes well outside the screen some 8000 yards from the merchant ships which they had been ordered to attack. The force turned 45° to port and then back to starboard to avoid the attack.

In the next stage, around 1318 hours, the German bombing attack, the enemy scored their one success. These aircraft were also intercepted on their way in but about a dozen of about twenty aircraft came through. They crossed the convoy from starboard to port and then dived to 3000 feet. They managed to damage the transport Deucalion which was leading the port wing column. More bombs fell close to several other ships.

Finally, at 1345 hours, the two Reggiane fighters approached HMS Victorious as if to land on. They looked like Hurricanes and HMS Victorious was at that time engaged in landing her own fighters. They managed to drop their bombs and one hit the flight deck amidships. Fortunately the bomb broke up without exploding. By the time HMS Victorious could open fire both fighters were out of range.

The Deucalion could no longer keep up with the convoy and was ordered to follow the inshore route along the Tunisian coast escorted by HMS Bramham. Two bombers found these ships late in the afternoon, but their bombs missed. At 1940 hours, however, near the Cani Rocks, two torpedo aircraft attacked and a torpedo hit the Deucalion. She caught fire and eventually blew up.

The convoy passed some 20 miles north of Galita Island and spent the afternoon avoiding enemy submarines which were known to be concentrated in these waters. There were innumerable reports of sightings and Asdic contacts and at least two submarines proved dangerous. At 1616 hours, HMS Pathfinder and HMS Zetland attacked one on the port bow of the convoy and hunted her until the convoy was out of reach. HMS Ithuriel, stationed on the quarter, then attacked, forced the enemy to surface and finally rammed her. She proved to be the Italian submarine Cobalto. Meanwhile HMS Tartar, on the starboard quarter, saw six torpedoes fired at close range at 1640 hours, and the next destroyer in the screen, HMS Lookout sighted a periscope. Together they attacked the submarine, continuing until it was no longer dangerous. There was no evidence this submarine was sunk.

At 1750 hours, HMS Ithuriel, which was on her way back to the convoy after sinking the Italian submarine Cobalto was attacked by a few dive-bombers, when still a dozen miles astern of the convoy. At this time the convoy came under attack by aircraft stationed on Sicily. This force numbered nearly 100 aircraft. Ju.87 dive-bombers as well as Ju.88’s and SM-79’s all with a strong escort of fighters. The enemy started attacking at 1835 hours, the bombers attacking from both ahead and astern which last was the direction of the sun. The torpedo aircraft came from ahead to attack on the starboard bow and beam of the convoy.

The Italian SM-79’s torpedo bombers dropped their torpedoes from ranges of about 3000 yards outside the destroyer screen, and once again the convoy turned away to avoid them. However the destroyer HMS Foresight was hit by a torpedo and disabled. The bombers chose HMS Indomitable as their main target. She was astern of HMS Rodney at the time on the port quarter of the convoy. Four Ju.88’s and eight Ju.87’s came suddenly out of the sun and dived steeply towards HMS Indomitable from astern. Some of the Ju.87 came down to 1000 feet and the carrier received three hits and her flight deck was put out of action. Her airborne fighters eventually had to land on HMS Victorious. HMS Rodney meanwhile had a narrow escape when a bomber attacked from ahead. One enemy aircraft was claimed to have been shot down by AA fire from the ships while the fighters claimed nine more although there were about twice as much enemy fighters in the air then British.

HMS Tartar took the damaged HMS Foresight in tow and proceeded westward for Gibraltar. Next day, as they were shadowed by enemy aircraft, and enemy submarines were known to be in the area, it was decided to scuttle the cripple before both ships might be lost. HMS Tartar then torpedoed HMS Foresight a few miles from Galita Island.

Passage through the narrows, 12-13 August 1942, and the loss off HMS Manchester.

These last air attacks took place about 20 nautical miles west of the Skerki Channel and at 1900 hours, when the attacks were clearly over, Vice-Admiral Syfret turned away with ‘Force Z’. It was now up to Rear-Admiral Burrough with ‘Force X’ to take the convoy to Malta.

At 2000 hours, when the convoy was changing it’s formation from four to two columns, the convoy was attacked by Italian submarines. The submarine Dessiè attacked a freighter with four torpedoes and claimed three hits. The sound of the torpedo hits was however not caused by her attack but by an attack by the Axum which hit three ships, HMS Nigeria, HMS Cairo and the tanker Ohio.

HMS Nigeria had to turn back to make for Gibraltar escorted by the escort destroyers HMS Derwent, HMS Wilton and HMS Bicester. Rear-Admiral Burrough transferred his flag to the destroyer HMS Ashanti. The stern of HMS Cairo had been blown off and she had to be sunk as she was beyond salvage with both engines also out of action. She was scuttled by HMS Pathfinder. The Ohio meanwhile managed to struggle on.

At this time the convoy was still trying to form up the the submarine attacks messed things up and right at thus time the convoy was once more attacked from the air in the growing dusk at 2030 hours. About 20 German aircraft, Ju-88’s made dive bombing and torpedo attacks, hitting the Empire Hope with a bomb and the Clan Ferguson and Brisbane Star with torpedoes. The first of these ships had to be sunk (by HMS Bramham, the second blew up but the last eventually reached Malta. Soon after this attack, at 2111 hours, HMS Kenya was torpedoed by the Italian submarine Alagi. She was able to evade three of the four torpedoes but was hit in the bow by the fouth. She was however able to remain with the convoy.

The situation was then as follows. HMS Kenya and HMS Manchester with two merchant ships, and with the minesweeping destroyers HMS Intrepid, HMS Icarus and HMS Fury sweeping ahead, had passed the Skerki Channel and were steering to pass Zembra Island on the way to Cape Bon. HMS Ashanti, with Rear-Admiral Burrough on board was fast overhauling these ships. The other two destroyers HMS Pathfinder, HMS Penn and the escort destroyer HMS Ledbury, were rounding up the remaining nine merchant ships. The escort destroyer HMS Bramham was also catching up after having escorted the single Deucalion until she sank.

On learing about the fate of HMS Nigeria and HMS Cairo, Vice-Admiral Syfret detached HMS Charybdis, HMS Eskimo and HMS Somali to reinforce Rear-Admiral Burrough. It would take these ships several hourse to catch up with the convoy.

The main body of the convoy passed Cape Bon around midnight. Fourty minutes later enemy Motor Torpedo Boats appeared and started to attack. Their first victim was HMS Manchester which was torpedoed at 0120/13 by the Italian MS 16 or MS 22. She had to be scuttled by her own crew. Many of her ships company landed in Tunisia and were interned by the Vichy-French but about 300 were picked up by destroyers (first by HMS Pathfinder, and later by HMS Eskimo and HMS Somali. These last two destoyers then set off towards Gibraltar.)

Four and possibly five of the merchant ships were also hit by the Motor Torpedo Boats. These were the Wairangi, Rochester Castle, Almeria Lykes, Santa Elisa and probably the Glenorchy. They were attacked between 0315 and 0430 hours about 15 nautical miles south-east of Kelibia whilst taking a short cut to overhaul the main body of the convoy. Four were lost, only the Rochester Castle survived and she managed to catch up with the main body of the convoy at 0530 hours. The Glenorchy was sunk by the Italian MS 31, the other four, of which the Rochester Castle survived as mentioned earlier, were hit by the German S 30 and S 36 as well as the Italian MAS 554 and MAS 557.

Shortly before 0530 hours HMS Charybdis, HMS Eskimo and HMS Somali had joined the main body of the convoy making the force now two cruisers and seven destroyers with the transports Rochester Castle, Waimarama and Melbourne Star. The damaged tanker Ohio was slowly catching up. With her was the escort destroyer HMS Ledbury. Astern of the main body was the Port Chalmers escorted by the destroyer HMS Penn and the escort destroyer HMS Bramham. The destroyers recued the crew of the Santa Elisa when the passed by the abandoned ship which was afterwards finished off by a German bomber. The Dorset was proceeding without escort and lastly the damaged Brisbane Star was still keeping close to the Tunisian coast independently, intending to steer towards Malta after nightfall.

At 0730 hours, Rear-Admiral Burrough, sent back HMS Tartar and HMS Somali to Kelibia to assist HMS Manchester and then go to Gibraltar. When they arrived they found out that the Manchester had been scuttled several hours earlier so they rescued those of her crew that had not reached the shore yet and then made off to Gibraltar as ordered. Besides crew of the Manchester they also picked up survivors from the Almeria Lykes and Wairangi.

The next encounter with the enemy was an air attack on the main body of the convoy at 0800 hours by German bombers. About 12 Ju.88’s made a shallow diving attack coming down from 6000 feet to 2000 feet to drop their bombs. Two dived on the Waimarama hitting her several times and she blew up immediately, one of the bombers was even destroyed in the explosion. HMS Ledbury saved some of her crew out of the blazing sea. At 0925 hours, when the Ohio, Port Chalmers and Dorset where with the main body again, a few Ju.87’s escorted by Italian fighters attacked. They dived down to 1500 to 1000 feet. HMS Kenya leading the port column, and the Ohio last ship but one in the starboard column, had narrow escapes. One of the enemy aircraft crashed on board the Ohio just after having released it’s bomb after being damaged by gunfire from the Ohio and HMS Ashanti. Another aircraft was claimed to have been shot down by fighters from Malta that had been patrolling overhead since daybreak.

Arrivals at Malta 13-15 August 1942.

At 1050 hours, about 20 bombers, mostly Ju.88’s with a few Ju.87’s, came in to attack. Target was the Ohio and she received four or five near misses and her engines were disabled. At the same time the Rochester Castle in the port column was near-missed and set on fire but she continued with the convoy. The Dorset which was astern of her was hit and stopped. The convoy went on leaving the Dorset behind with the Ohio and two destroyers.

At 1125 hours the last air attack on the main body took place. Five Italian SM.79’s attacked with torpedoes and almost hit the Port Chalmers as the torpedo got stuck in the paravane. Further attacks on the main body were held of by fighters from Malta. At 1430 hours, four minesweepers from Malta joined the main body of the convoy, these were HMS Speedy (Lt.Cdr. A.E. Doran, RN, with the group’s commander A/Cdr. H.J.A.S. Jerome, RN on board), HMS Hebe, HMS Rye and HMS Heyte. Also with them were seven Motor Launches; ML 121, ML 126, ML 134, ML 135, ML 168, ML 459 and ML 462. HMS Rye and two of the ML’s were sent towards the damaged Ohio which was ‘vital for Malta’, according to A/Cdr. Jerome.

At 1600 hours, Rear-Admiral Burrough, set course to the west with his two cruisers and with five destroyers. The Port Chalmers, Melbourne Star and Rochester Castle arrived in Grand Harbour around 1800 hours with the force of A/Cdr. Jerome. The Rochester Castle was by that time very low in the water, she had just made it into port on time.

Out were still the Ohio, Dorset and the Brisbane Star. The valuable Ohio had been helpless with HMS Penn and HMS Bramham. When HMS Rye arrived at 1730 hours, HMS Penn took the Ohio in tow. Meanwhile HMS Bramham was sent to the Dorset but soon afterwards German bombers came again and the ships were attacked repeatedly until dark. Both merchantman were hit around 1900 hours and the Dorset sank.

At daylight on the 14th HMS Ledbury arrived to help bringing the Ohio to Malta. HMS Speedy also soon arrived on the scene with two ML’s. The rest of his force he had sent to search for the Brisbane Star. At 1045 hours, enemy aircraft made their last attempt, causing the parting of the tow. Fighter from Malta shot down two of the attackers. The tow was passed again and the slow procession went on and in the morning of the 15th the vital tanker finally reached Malta.

The Brisbane Star had by then also arrived. She left the Tunisian coast at dusk on the 13th. Aircraft had attacked her unsuccessfully and one of the attackers was shot down by a Beaufighter escort that had been sent from Malta. She arrived at Malta in the afternoon of the 14th.

Italian surface ships to operate against the convoy ?

The convoy had experienced the violence of the enemy in every shape except that of an attack by large surface ships. Yet Italian cruisers and destroyers had been at sea to intercept and attack it. Two light cruiser had left Cagliari in the evening of 11 August 1942 and the heavy cruisers Gorizia and Bolzano from Messina, and a light cruiser from Naples had sailed on the morning of the 12th. That evening reconnaissance aircraft reported one heavy and two light cruisers with eight destroyers about 80 nautical miles to the north of the western tip of Sicily and steering south. It would have been possible for this force to meet the convoy at dawn on the 13th so the shadowing aircraft was therefore ordered in plain language to illuminate and attack. This apparently influenced the Italians as they had limited air cover and they turned back at 0130/13 when near Cape San Vito. At 0140 hours the aircraft reported that it had dropped its bombs but no hits had been obtained. Similar orders were signalled, in plain language, to relief shadowers and to report the position of the enemy force to the benefit of imaginary Liberator bombers in case the Italians would change their minds and turn back. They however held on to the eastward.

The submarine HMS P 42 sighted them around 0800/13 off Stromboli and attacked with four torpedoes claiming two hits. She had in fact hit the heavy cruiser Bolzano which was able to proceed northwards and the light cruiser Muzio Attendolo which managed to reach Messina with her bows blown off. The other cruisers went to Naples. Following the attack P 42 was heavily depth charged by the destroyers but managed to escape.

In fact the following Italian ships had been at sea; heavy cruisers Gorizia, Trieste, Bolzano, light cruisers Eugenio di Savoia Raimondo Montecuccoli, Muzio Attendolo. They were escorted by eleven destroyers; Ascari, Aviere, Camicia Nera, Corsaro, Fuceliere, Geniere, Legionaro, Vincenzo Gioberti, Alfredo Oriani, Grecale and Maestrale.

The return to Gibraltar.

The British ships returning to Gibraltar had better fortune. Having left the convoy off Malta in the afternoon of the 13th, they rounded Cape Bon around 0130/14 and from that point until past Zembra Island they successful ran the gauntled of E-boats laying in wait.

at 0450/14, near the Fratelli Rocks, a submarine fired torpedoes at HMS Ashanti from the surface. She was nearly rammed by HMS Kenya, which was next astern of the ‘flagship’ (Rear-Admiral Burrough was still in HMS Ashanti). The inevitable shadowers arrived soon after daylight to herald their air attacks that began at 0730 hours. They lasted until around 1315 hours. German bombers came in first with three attemps by a few Ju.88’s. This was followed by a more severe attack with about 30 bombers, Ju-88’s and Ju-87’s between 1030 and 1050 hours. An hour later 15 Savoia high-level bombers attacked followed until 1315 hours by torpedo-carrying Savoia’s. Around 20 aircraft attacking single or in pairs. Also aircraft are though to be laying mines ahead. Several ships were near missed, but no further damage was sustained. After these attacks the British were left alone and in the evening they joined ‘Force Z’.

Vice-Admiral Syfret had gone as far west as 01’E where he ordered the damaged carrier HMS Indomitable to proceed to Malta with HMS Rodney and a destroyer screen made up of HMS Ithuriel, HMS Antelope, HMS Amazon, HMS Westcott, HMS Wishart and HMS Zetland. He then turned back to the east to make rendez-vous with Rear-Admiral Burrough. HMS Rodney, HMS Indomitable, HMS Ithuriel, HMS Antelope, HMS Amazon, HMS Westcott, HMS Wishart and HMS Zetland arrived at Gibraltar in the evening of the 14th.

A few hours before they arrived the damaged HMS Nigeria and her escort had also entered port, as had HMS Tartar, HMS Eskimo and HMS Somali. On her way back HMS Nigeria had been attacked by torpedo-bombers and a submarine but she had not been hit.

Conclusion.

Out of the fourteen ships that had sailed only five arrived ‘safe’ at Malta. This was not a very high score also given the very heavy escort that had been provided also taken in mind that an aircraft carrier, a light cruiser, an AA cruiser an a destroyer had been lost and two heavy cruiser had been damaged. But the convoy had to meet very heavy air attacks by over 150 bombers and 80 torpedo aircraft, all in the space of two days. Also these aircraft were protected by fighter in much greater strength that the carriers and Malta could provide. And there were also the enemy submarines and E-boats.

The spirit in which to operation was carried out appears in Vice-Admiral Syfret’s report: ‘ Tribute has been paid to the personnel of His Majesty’s Ships, both the officers and men will desire to give first place to the conduct, courage, and determination of the masters, officers, and men of the merchant ships. The steadfast manner in which these ships pressed on their way to Malta through all attacks, answering every maneuvering order like a well trained fleet unit, was a most inspiring sight. Many of these fine men and their ships were lost. But the memory of their conduct will remain an inspiration to all who were privileged to sail with them. ‘ (7)

HMS P 34 (Lt. P.R.H. Harrison, DSC, RN) fired four torpedoes against an enemy convoy in the central Mediterranean about 45 nautical miles south-west of Schiza Island, Greece in position 36°17'N, 21°03'E. All torpedoes fired missed their target.

The convoy consisted of Ravello (6142 GRT, 1941), Manara (7124 GRT, 1942), Sestriere (7991 GRT, 1942) and Ankara (4768 GRT, 1937) escorted by the destroyers Aviere, Legionario, Fuciliere, Bombardiere, Geniere, Camicia Nera, Corsaro, Freccia and Lampo and the torpedo boats Pegaso, Partenope and Procione. Ravello and Sestriere reported to have been missed by the torpedoes, Lampo dropped intimidation depth charges and Aviere who had sighted the torpedo tracks carried a depth charge attack but signalled the results as negative.

(All times are zone -2)
0823 hours - Sighted patrolling aircraft to the North-West. The convoy we were warned about must be approaching.

0835 hours - Sighted masts and funnels of the approaching convoy bearing 305°.

0840 hours - Started attack on the convoy which was soon seen to be made up of three large merchant ships in line ahead. Many destroyers formed the escort. Several aircraft were also overhead. The leading merchant vessel was an older type of about 6000 tons, the other two were modern ones of 9000 tons.

0921 hours - In position 36°17'N, 21°03'E fired four torpedoes at the rear ship from 7000 yards. Seventeen seconds after firing the first torpedo there was a very heavy explosion just ahead of P 34. The first torpedo must have prematured after running off its safety range.

0927 hours - Heard a torpedo exploding giving a running range of 8000 yards corresponding with the range on firing of 7000 yards.

0936 hours - A counter attack commenced by three destroyers using hydrophones. Several patterns of depth charges were dropped rather close but to shallow. P 34 was at 120 feet at the time.

1030 hours - An Asdic fitted destroyer took over the hunt from the other three.

1056 hours - The destroyer passed overhead and dropped a pattern of four depth charges very close causing some damage.

1226 hours - After hearing no HE and no Asdic transmissions for a while started to return to periscope depth.

1236 hours - Head Asdic transmissions on the starboard beam.

1238 hours - At periscope depth. Saw a destroyer at a range of 2500 yards on our starboard beam. Went deep again. The destroyer was in Asdic contact.

1258 hours - The destroyer passed overhead and dropped a pattern of 5 depth charges which were again very close causing some more damage. This was followed by another pattern a bit further off about one minute later. P 34 remained deep for the remainder of the afternoon.

1700 hours - Returned to periscope depth. Nothing in sight. During the counter attack a total of 83 depth charges had been counted.

1715 hours - Went ahead on the port shaft. This resulted in clouds of black smoke which soon filled the submarine. A fire had started, as a result of damage from the depth charging, when starting up the motor so the port motor was placed out of action.

1744 hours - Surfaced for 5 minutes to clear the boat of the smoke.

2124 hours - Surfaced and set course to return to Malta as a result of the damage inflicted by the depth charging. (8)
