Appendix XV Organisation of Allied Submarines September 1944

ON 12TH SEPTEMBER 1944, Rear Admiral GE Creasy CB CBE DSO MVO hoisted his flag as A(S) in place of Rear Admiral CB Barry, who had had to relinquish the appointment a month earlier because of illness. Rear Admiral Creasy was not a submarine specialist. He came from the Headquarters of the Allied Naval Command of the Expeditionary Force where he held the appointment of Chief of Staff during the Normandy landings. Formerly he had been in the Admiralty as the Director of Anti-Submarine Warfare at the height of the Battle of the Atlantic. Previously he had commanded the new battleship Duke Of York in the Home Fleet and before that the First Destroyer Flotilla. He was of wide experience in the service and an officer of outstanding ability destined for high rank. The Submarine Command was indeed fortunate to secure the services of this exceptional officer. Admiral Creasy, on his arrival, found three Chief Staff Officers, all submarine specialists, to assist him. Captain GBH Fawkes CBE RN was Chief Staff Officer(Operations), Captain GC Phillips DSO GM RN was Chief Staff Officer(Administration and Personnel) and Captain JRS Brown RN was Chief Staff Officer(Material).

Rear Admiral Creasy brought with him very definite ideas on the fundamental purpose of the submarine branch in the Royal Navy. With his experience of the Battle of the Atlantic he was certain that the submarine was the greatest menace to our command of the sea. He was, however, strongly opposed to the British abolitionist policy in fashion after the First World War, and believed that this would have been fatal to us if it had been adopted. We would then probably not have developed asdic, or for that matter, any other anti-submarine measures. He believed that we should develop the submarine to the maximum, and should be in the lead in this in the navies of the world. Our anti-submarine methods would then have the most modern opposition against which to develop. He was, in common with many officers experienced in anti-submarine matters, critical of the British submarine branch for failing, between the wars, to warn them of the dangers of the night surface attacks and of the pack tactics employed by the U-boats. He was far from happy with the views of the staff of A(S), when intelligence of the 'schnorchel' was first obtained, who poured cold water on it and referred to it as a dangerous device for a submarine and nothing to worry about!1 British submarine development during the war had been confined mostly to small changes found necessary during their operations. No new type of submarine had as yet been put into service and the three prewar T, S and U-classes had been mass-produced and only slightly improved. The principal developments introduced had been the wholesale silencing of machinery so that it could not be picked up by hydrophones; the introduction of radar and a slight increase in diving depth obtained by using welding and higher-grade steel. A magnetic ground mine launched from the torpedo tubes had been developed. There were also such minor improvements as air conditioning, air purification, flashless cordite for guns, the magnetic non-contact pistol for torpedoes and the mine detecting unit for the asdic set. All of this had been developed to help our submarines in their operations against the Germans, Italians and Japanese, who had only inferior asdic sets and low powered radar, neither of which caused us very much concern. British submarine development, as shown in the new A-class under construction, emulated the submarines of the US Navy: it was to be a fast submarine on the surface fitted with centimetric radar. The American submarine tactics in the Pacific were basically the same as those used by the Germans before 1943 in the Atlantic, but with the addition of radar and very high frequency voice radio. They were proving devastating against the Japanese. However they would not have worked against our anti-submarine forces in the Atlantic. They would have been defeated by radar in ships and aircraft and by efficient asdic. This the Germans already knew and they had embarked on a more radical stage of submarine development. This was to produce boats that would counter radar by remaining submerged continuously. This was first to be done by fitting 'schnorchel' to existing U-boats. The price, however, was that they lost their surface mobility. Furthermore 'schnorchel' did nothing to protect them against asdic and they became, in fact, more vulnerable than before as they found it too dangerous to attack on the surface at night, and so lost their immunity from detection by asdic. To help against asdic they had developed decoys to confuse the escorts, and homing torpedoes with which to attack them.

The next stage of German submarine development was more fundamental and that was the design of the type XXI and type XXIII U-boats. In these, submerged qualities were greatly increased at the expense of surface qualities. In addition to an improved 'schnorchel', they would have enlarged high capacity batteries and powerful electric motors to give them a submerged speed of 16 knots or so. This should render them practically immune to attack by the slow sinking depth charge and would greatly decrease the effectiveness of the new 'Squid' and 'Hedgehog' ahead throwing weapons. These German plans had been revealed to us by the cryptographers2. Intelligence also indicated that U-boats of even greater submerged speed and endurance were being developed in Germany. These reports caused great alarm in the Admiralty. If effective counter measures were to be devised, fast, submerged submarines must be available for experimental purposes and for training. They must be available before the new German U-boats, which were known to be building in quantity, came into service. The first suggestion was to modify an S-class submarine to give a submerged speed of 12 knots. Seraph had already been put in hand at high priority to be streamlined and given high capacity batteries to meet this need. The second important move was to fit a dummy 'schnorchel' to a training submarine on which to practise attacks. Vulpine was so fitted and these two measures received fresh impetus from Rear Admiral Creasy, who also obtained Admiralty approval to fit three British submarines with full workable 'schnorchels'. He accepted that this device was not required operationally at present, but it would be available for realistic trials with anti-submarine devices and could be fitted to all operational submarines should this become necessary.

Rear Admiral Creasy did not at once propose any alterations to the main British submarine building programme. The end of the campaign in the Mediterranean provided a number of modern U-class submarines, which were of too limited endurance for use in the Far East. These were now available to replace most of the elderly pre-war submarines now employed for training and allowed the older submarines, which were becoming difficult to maintain, to be scrapped. There were, however, a number of V-class still building which were now surplus to requirements and some of these were transferred to the French, Greek and Norwegian Navies and later to the Danish Navy too. A problem of immediate concern to A(S) was the performance of the CCR pistol for torpedoes. Meetings were held with the Admiralty and the results analysed. At the end of 1944 it had been reluctantly concluded that the number of premature explosions were such that the non-contact setting, which detonated the torpedo under the target with much greater effect than against the side, could no longer be used. In future all torpedoes must be set to hit and to fire on contact. There were many other important issues for the new A(S) to decide, especially the strength and logistics of the submarines in the Far East and he decided he must visit the area as soon as possible.

THE STRATEGIC SITUATION IN HOME WATERS when Rear Admiral Creasy took command was that the Allied armies had broken out of the Normandy bridgehead and had over run most of France. German garrisons were, however, cut off in Bordeaux, La Rochelle, Lorient and Nantes. The German U-boats had abandoned their French bases and had retired to Norway or Germany itself. Most of them were now fitted with 'schnorchel' and they had begun their inshore campaign close around the British Isles. The coastal route to north Norway was now of increased importance to the Germans. Since the Finnish armistice with the Soviets in September, they had to supply an army of eight divisions fighting the Russians in the Far North entirely by this route. The minelaying by Bomber Command in the Baltic had caused the Swedes so many casualties that they refused to let their ships go to German ports and so practically all the iron ore had now to use the Norwegian coastal route even in summer. Of the German main units, only the damaged Tirpitz remained in Norway with four destroyers at Alten Fjord. Although she was never expected to be fully operational again, our intelligence believed that she would shortly be able to move at slow speed. Tirpitz and five destroyers in fact made a short sortie from Alten Fjord into the Arctic for exercises between 31st July and 1st August. The other German main units were all in the Baltic: the pocket battleship Scheer was at Kiel and Lutzow at Swinemunde but the battle cruiser Gneisenau was out of action at Gdynia. The cruisers Prinz Eugen, Hipper, Leipzig, Koln, Nurnberg and Emden were all believed to be ready for sea.

At the beginning of September, when Rear Admiral Creasy took over, there were six Allied submarines operational in Home waters but another nineteen were doing trials and were working up and most of them were to go to the Far East. Six submarines were employed on submarine training and eighteen on anti-submarine training while another twenty-four were refitting. The six operational submarines were Sceptre, Satyr, Venturer and Viking and the French Rubis and the Norwegian Ula. Sceptre was in the Third Submarine Flotilla in the Clyde and the others in the Ninth Flotilla at Dundee. In August the nights became long enough for submarines to patrol off the Norwegian coast and it was decided to use the six operational submarines against the German coastal traffic, while the working up patrols by new and refitted submarines would continue to be for anti U-boat purposes in the Shetlands area. Submarines, now that they had been joined by other forces in the attack on the Norwegian coast route, had become very much the junior partners for this task. In addition to the intensive mining campaign in the Baltic by Bomber Command, Coastal Command had now moved strong anti-shipping striking forces north and Norwegian Motor Torpedo Boats were now stationed in the Shetlands. The Home Fleet also made periodical strikes and minelays with carrier borne naval aircraft and surface ships. There were plenty of targets for all but there were also problems in operating so many forces in the same area, especially for Coastal Command and our submarines.

The first submarine to return to the Norwegian coast was Satyr (Lieutenant TS Weston DSC RN), who patrolled off Skudenes between 18th and 27th August. On 20th she attacked a convoy of four ships with three escorts firing five torpedoes at a range of 2200 yards. There was no result except an ineffective counter attack and she either missed or the CCR pistols failed or prematured. Two days later off Egeroy she had another chance and fired six torpedoes at a convoy of five ships with eight escorts at a range of 2500 yards, but although explosions were heard at approximately the right interval, these were torpedoes hitting the cliffs. Satyr was relieved by Viking (Lieutenant R Bannar Martin DSC RN), who patrolled in the Karmay and Lister area from 30th August to 5th September. On 1st, she attacked a supply ship in convoy at a range of 5000 yards with four torpedoes with CCR pistols and heard explosions at the right time but these must have been prematures as the ship was not hit. On 4th, she sighted a large tanker with six escorts and fired another salvo of four torpedoes at 3000 yards with the same negative result. Venturer (Lieutenant JS Launders DSC* RN), off Skudenes from 5th-16th September, had better luck or was more skilful. On 11th she fired a full salvo of four torpedoes, which hit and sank Vang of 678 tons at a range of 1300 yards. Two days later she fired another full salvo of four torpedoes at a range of 1200 yards, hitting and sinking Force of 499 tons. Both ships had escorts but their size was greatly over-estimated. These torpedoes had CCR pistols but were set to run at a depth of eight feet and may have exploded on contact. Nevertheless they did not fire prematurely.

Allied convoys to North Russia were started again in August and although the Luftwaffe in Norway was much weaker than before, they were still menaced by a strong force of U-boats. Tirpitz, although by no means operational, was believed to be nearing the stage where she would be able to move. It was, however, thought that the few Allied operational submarines available would be better employed against the coastal traffic in Norway rather than to patrol off Alten Fjord to cover the convoy against a sortie by Tirpitz. In any case the Soviet submarines were active on the north coast of Norway. Four boats were out in the second half of August and they made four attacks. M201 sank the patrol vessel V6112 off Persfjord and S15 hit and damaged a ship of 5483 tons off the Nordkyn but she was towed in.

In September it was decided to make another X-craft attack on the floating dock in Bergen. X24, the same craft as before but under a new Commanding Officer, was selected for this operation. X24 (Lieutenant HP Westmacott DSC RN) left the Shetlands on 7th September towed by Sceptre (Lieutenant IS McIntosh DSO DSC RN). On the passage, heavy weather was encountered and an officer was lost overboard from an X-craft and drowned. X24 was slipped off Feje and entered Bergen successfully. She laid her charges under the dock on the morning of 11th and withdrew without further incident. That night she made contact with Sceptre and was towed back to Balta Sound in the Shetlands. This perfectly executed attack damaged the dock beyond repair and also seriously damaged Sten of 1820 tons and Kong Oscar II of 914 tons, which were alongside at the time.

It is appropriate here to note what the future plans were for X-craft at this time. During 1944 it seemed clear that the best targets for X-craft were the heavy ships of the Japanese Navy in the Far East. The depot ship Bonaventure (Captain WR Fell OBE RN) was already available to carry six X-craft and to maintain them and was capable of giving them a worldwide strategic mobility. A new class of X-craft was therefore designed especially for the Far East. They were known as XE-craft and they were practically the same as the X20-class except that they had a more streamlined casing and were fitted with air conditioning machinery3. Twelve XE-craft were ordered from the Broadbent group and by the end of 1944, the first six XE-craft had been completed and were sent to Bonaventure forming the Fourteenth Submarine Flotilla under the command of Captain Fell. Six T-class submarines of the Fourth Submarine Flotilla had been fitted to tow them and, anticipating the long distances involved in the Far East, each XE-craft was allowed two passage crews as well as her operational crew. The Fourteenth Submarine Flotilla sailed for the Far East by the Panama Canal during February 1945.

Immediately after towing X24 back to the Shetlands, Sceptre sailed to relieve Venturer off Skudenes. On 20th September, she fired three torpedoes at a range of 1000 yards at a small merchant ship and missed. This time the CCR pistol could not be blamed as the torpedoes were fitted with the old fashioned contact pistols. The same day, after dark, she made contact with a convoy at 11,000 yards by radar. She made a surface attack and fired a full salvo of six torpedoes at a range of 2200 yards securing four hits on two ships and sinking Vela of 1180 tons and the escort vessel M132. These torpedoes were also fitted with old-fashioned contact pistols. Sceptre left patrol on 21st September and the French submarine Rubis arrived on 24th and laid 32 mines off Egeroy. This field was most successful and sank KnuteNelson of 5749 tons, Claire Hugo Stinnes of 5295 tons and the escort vessels UJ1715 and UJ1106. Satyr (Lieutenant TS Weston DSO DSC RN) patrolled off Tennholm from 24th September to 2nd October but the visibility was bad throughout this period and she only sighted one small ship on 30th. She fired four torpedoes with CCR pistols set to non-contact at a range of 1400 yards but without result. During September too, Seascout (Lieutenant JW Kelly RN), Thrasher (Lieutenant Commander MFR Ainslie DSO DSC RN) and Trump (Commander EF Balston DSO RN) carried out anti U-boat working up patrols in the North Sea and east of the Orkneys but saw nothing.

In October Ula (Kapteinloytnant RM Sars) patrolled off Lister but sighted nothing and Sceptre (Lieutenant IS McIntosh DSO DSC RN) arrived to relieve her. Our intelligence kept us informed of the positions of the German minefields off the Norwegian coast behind which their convoys were routed. Our submarines were therefore able to penetrate the mine barriers and patrol submerged behind them by day lying in wait for the convoys. By night, however, they had to withdraw to seawards to charge their batteries. At this time, however, the Germans decided that their convoys should only proceed at night and so avoided attack by our submarines, which were out at sea charging. On the night of 21st/22nd September, Sceptre sighted a large convoy off Egersund from outside the minefields. She fired four torpedoes in a surface attack at a range of 3500 yards across the barrier. She heard two hits and, in fact, sank UJ1111, one of the escorts, which broke in half and blew up. She also sank a ship of 2207 tons. The Germans then suspended all traffic for twenty-four hours. Sceptre went home on 26th and was relieved by Satyr (Lieutenant TS Weston DSO DSC RN) who had a blank patrol before returning to base on 7th November. Meanwhile Rubis (Capitaine de Corvette H Rousselot) had put to sea with another load of mines, which she laid off Feje on 18th October. This field, however, did not sink anything. Viking (Lieutenant R Bannar-Martin DSC RN) had been sent to patrol farther north and was off Bodo from 3rd to 19th October. The weather was very bad but on 14th, she sighted a northbound convoy in Fleinvaer and fired four torpedoes at 1500 yards, hitting and sinking the Norwegian Standard of 1286 tons. During October too, Silene (Lieutenant Commander HRB Newton DSC RN), Varne (Lieutenant IG Raikes DSC RN) and Seadog (Lieutenant EA Hobson DSC RN) carried out anti U-boat working up patrols east of the Shetlands but saw nothing. The German U-boats were now nearly all fitted with 'schnorchel' and so did not need to surface on passage either by day or night, and this was probably the reason that our patrols never seemed to sight them.

So far, since the return of our submarines to the Norwegian coast, they had sunk, by X-craft, mines and torpedoes, a floating dock, six ships of 14,687 tons and four escort vessels and had damaged two more ships of 2734 tons. Other forces had been busy too. Naval aircraft from Home Fleet aircraft carriers, in a series of strikes, sank three ships of 3,145 tons and three minor war vessels, and damaged twelve more ships of various types. Coastal Command air strikes sank twelve ships of some 8000 tons and an escort vessel and our Motor torpedo boats four ships of 10,960 tons, and another three minor war vessels. These results were making it difficult for the Germans to keep their army supplied in North Norway and were substantially cutting down their imports of iron ore. In most of these anti-shipping operations there was little mutual interference. The naval aircraft laid mines and made their attacks inside the leads where our submarines could not go. Our submarines attacked where the traffic was forced into the open sea by geography. In anti U-boat operations, however, Coastal Command found themselves severely hampered by the bombing restrictions necessary to protect our submarines. With the need to give our submarines reasonable freedom of action and to allow for navigational errors by ships and aircraft, the areas covered by the bombing restrictions were very large, as a glance at the map will show. During October, there were discussions between A(S) and the Admiralty with Coastal Command to try and resolve the matter. In the end, the Admiralty decided not to send submarines to southwest Norway for a trial period of three weeks starting on 1st November to give Coastal Command a free hand against U-boats south of 62 30' N. The Russians deployed five submarines on the north coast of Norway in September but without success, and their own aircraft sank Shch402 in error.

November was a stormy month but eight submarines made patrols. Four of these were working up and their areas were in the middle of the North Sea, south east of the Shetlands, where they might catch a U-boat on passage. These submarines were Torbay, Solent, Scythian and the Norwegian Utsira, and none of them saw anything. Of the operational boats, Ula (Kapteinloytnant RM Sars) was sent north to patrol off Fro Havet from 4th-24th November and Venturer (Lieutenant JS Launders DSC* RN) to the north of the Lofotens off And Fjord from 10th- 19th. Ula's patrol was blank but on 11th, Venturer sighted a U-boat on the surface. She was able to close to 2000 yards and fire four torpedoes, one of which hit and sank U771. This boat was one of the Panther Group operating in the Arctic against the convoys to North Russia. She then closed the coast to land supplies for the clandestine shipping-reporting organisation. The day after Venturer sank U771, Bomber Command finally sank Tirpitz. She had been moved to Tromso and thirty-two Lancaster bombers, each carrying a 12,000 lb. bomb attacked her from high altitude. Three direct hits and two near misses caused her to blow up and capsize. The only seagoing warships of the German Navy now left in Norway were four fleet destroyers. In the middle of November, the Home Fleet took advantage of the absence of our submarines from southwest Norway and sent in the cruisers Kent and Bellona, with four destroyers, to the vicinity of the Lister Light. Here they attacked a convoy sinking a merchant ship and five escort vessels. The three-week period free of bombing restrictions for Coastal Command was now over and on 18th November, two submarines left Lerwick to resume patrols in this area. Sokol took up a position off Skudenes and Rubis laid 32 mines on 24th off Egersund. This field caught and severely damaged Castor of 1683 tons.

Analysis of the three weeks clear field for Coastal Command off the southwest coast of Norway showed that their anti-submarine aircraft had achieved nothing. Five U-boats had, however, been seen by anti- shipping strike aircraft and one had been attacked by an aircraft with no depth charges. With Venturer's success against U771 during the same period, it was decided that submarines should continue to operate off the southwest coast of Norway. Coastal Command now questioned the anti U-boat working up patrols by submarines which denied considerable areas to their aircraft. Here they were on firmer ground. No U-boat had been sunk by a submarine on a working up patrol for over two years. A(S) was reluctant to give up these patrols. They were ideal as a final exercise for submarines before carrying out patrols against opposition, and it was desirable that they should conduct them on the Home station under the supervision of Captain(S) Third Submarine Flotilla. At first, however, the Admiralty came down on the side of Coastal Command and no working up patrols were carried out during December and Sleuth had to leave for the Far East without a working up patrol. Subsequent discussions, however, arrived at a compromise with Coastal Command, and working up patrols were resumed in January 1945.

Three patrols were carried out in December 1944. Utsira (Loytnant S Valvatne) patrolled off Fro Havet between 11th and 17th December. On 14th, she sighted a U-boat with a small escort early in the morning. She fired a full salvo of four torpedoes at a range of 2000 yards but she missed. Two days later she got another chance off Halten, this time at a range of 1000 yards and she fired her second full salvo of four torpedoes. This time she thought she had hit but it proved to be a premature by a CCR pistol. Venturer's patrol was off Egeroy and Obrestadt from 15th-28th but she saw nothing at all. The third patrol was another minelaying sortie by Rubis. She laid 32 mines off Jaederens on 19th and was back in Dundee for Christmas. This minefield sank the escort vessels UJ1113 and UJ1116; the minesweeper R402 and the merchant ship Weichselland of 3583 tons. Rubis was now due for refit but because of the shortage of refitting yards and her age, it was decided not to take her in hand. France now having been liberated, it was possible to send her crew on leave. Rubis, since the fall of France in 1940, had laid 683 mines sinking fourteen ships of 21,410 tons and damaging another of 1683 tons. Her mines also sank seven minor war vessels and damaged a U-boat. She also sank a ship of 4300 tons by torpedo. Rubis, under her two able Commanding Officers (Capitaines de Corvette GEJ Cabanier and H Rousselot) fought a splendid war, and she was a great credit to her country and now a sad loss to her comrades of the British submarine branch.

It had originally been hoped that the Germans would have been defeated by the end of 1944. The German attacks with V1 and V2 weapons, the failure to cross the lower Rhine at Arnhem, the time taken to open the port of Antwerp and the German counter offensive in the Ardennes, however, all delayed matters. On 1st January 1945, therefore, although most of France and Belgium had been liberated, the main armies were still well short of the Rhine and most of Holland remained in enemy hands. On the eastern front, the Red Army had reached the frontiers of Germany. In Norway, a large German army of 170,000 men in the far north was also retreating, and the enemy hoped to withdraw it to the Narvik area to defend the vital iron ore mines. A large amount of shipping had been amassed there for this purpose. Although the end for Germany was in sight and clearly only a matter of time, the Admiralty were seriously alarmed that a new campaign with the Type XXI and Type XXIII U-boats was about to begin, and they were pessimistic about coping with it. The conventional U-boats using the 'schnorchel' had already virtually countered radar in anti-submarine warfare, especially when used from aircraft, and the U-boat campaign in inshore waters was only being held by a huge force of surface escorts using asdic. The Type XXI, with its high underwater speed, not only threatened to render counter attacks using asdic ineffective, but also to restore some of the mobility totally submerged which the conventional U-boats had lost when 'schnorchelling'. The German Navy had a huge building programme of Type XXI U-boats and some fifty were nearing completion.

Our submarine policy, except for the conversion of half a dozen S-class into fast anti-submarine targets and the fitting of more dummy 'schnorchels' to the U-class, remained unchanged. The use of our submarines on anti U-boat patrols against the Type XXI did not show promise. Indeed the introduction of the 'schnorchel' seemed already to be responsible for a dearth of sightings: the considerable effort expended on these patrols by submarines working up had produced no results at all. U771 sunk by Venturer was caught on the surface and this type of attack was unlikely to occur with the Type XXI. The policy therefore was continued of sending most of our submarines to the Far East, and only keeping a few operational boats at home.

AT THE BEGINNING OF 1945, there were few operational submarines at home, but eight others were working up and doing trials. Utsira (Loytnant. S Valvatne) patrolled off Fro Havet from 6th-19th January. On 11th just before midnight, she sighted a U-boat escorted by an anti-submarine trawler and fired four torpedoes at 800 yards but they had CCR pistols and they fired prematurely so the U-boat escaped. After this disappointment she had to wait four days for another target. On 16th she sighted what she took to be a small merchant ship two hours after midnight. She fired a salvo of four torpedoes at a range of 1200 yards and this time the CCR pistols did not let her down. She secured a hit and sank the German Naval Auxiliary V6408 of 1281 tons. Venturer (Lieutenant JS Launders DSC* RN) patrolled off Skudenes from 18th- 25th January but was severely handicapped for most of the time by having one engine out of action. However on 20th she fired four torpedoes at a convoy at a range of 3500 yards but missed. Two days later in a night attack she fired four torpedoes at another convoy at 6000-6500 yards on a late track. Surprisingly one torpedo hit and sank Stockholm of 618 tons. Agreement was now reached with Coastal Command to send four working up submarines on anti U-boat patrols. Seanymph (Lieutenant MI Usher RN) was placed east of the Orkneys from 3rd-17th, as was Dolfijn (Luitnant ter zee 1e Kl Maas) from 6th- 11th. Taciturn (Lieutenant Commander ET Stanley DSO DSC RN) was off the east coast of Scotland from 23rd- 30th and finally Sibyl (Lieutenant HR Murray RN) was placed in a similar area. Not one of these submarines even sighted a U-boat and the only incident was that Dolfijn was machine gunned by an RAF Mosquito aircraft in a total attack restriction area. Her periscopes and bridge were damaged putting her out of action for a month.

Three of the large German destroyers, which had been intended as escort for Tirpitz, left for Germany on 26th January. There were no submarines on the Norwegian coast at the time. Venturer had just left Fro Havet for base. The German ships were, however intercepted and engaged by the cruisers Diadem and Mauritius off Bergen and were damaged.

In February, A(S) set off on his Far East tour, which lasted over a month. He conferred with C-in-C of the British Pacific Fleet and C-in-C, East Indies. He also conferred with the United States Commanders in the Pacific and settled the composition and disposition of the British submarines in the East Indies and the Pacific for the rest of the war. These will be dealt with later in the Chapters dealing with the Far East. It will be recalled that it was the plan to have forty boats operational in the Far East by January 1945. Due to delays in the building programme, especially of the A-class, and in the refits of other types, the total number operational was, on Rear Admiral Creasy's arrival, less than thirty, and did not reach forty until the end of April. The problem was not manpower, there were, in fact, another seven submarines in the Far East for anti-submarine training, but these were V-class and of too short endurance to be used on operations. To keep forty submarines operational would have needed a fourth submarine flotilla east of Suez. The liner Montclare had been converted in the USA as depot ship. She, however, had been taken by the Admiralty for duty in the Pacific Fleet Train and was no longer available. It was, however, decided, and this was approved by the Admiralty in April, that all long-range submarines of the T and A-classes should be sent east and three short range T-class (Torbay, Thrasher and Trident) should be employed in the East Indies. The available S-class, some fourteen boats, would be divided equally between the Pacific and East Indies.

While A(S) was away, operations in Home waters continued as before. Venturer (Lieutenant JS Launders DSO DSC* RN) patrolled off Feje from 4th February to 15th. On the forenoon of 9th she detected a U-boat by hydrophone effect on her asdic and then sighted a periscope on the bearing. Lieutenant Launders stalked the enemy for an hour, plotting her course and speed using asdic and making a few sightings of her periscope. Just after noon he fired four torpedoes set to depths of 30 and 36 feet at a range of 2000 yards, and aimed by hydrophone bearing on asdic. One hit was obtained and U864 was sunk and lost with all hands. Although Venturer never sighted a 'schnorchel', it seems likely from the amount of noise the U-boat was making, that she was, in fact, 'schnorchelling'. The sighting of the periscope was probably due to its liberal use when 'schnorchelling' and the fact that it was arranged in the U-boats to look over the top of the 'schnorchel' and so was generally high out of the water. The other three submarines that patrolled during February saw nothing. These were Viking (Lieutenant R Bannar-Martin DSC RN) off Fro Havet from 16th February to 4th March; Dolfijn (Luitenant ter zee 1e Kl Maas) east of the Orkneys from 5th-16th February and the Free French Morse4 from 14th-24th February in the same area.

In March, the Germans began to withdraw from Norway and there was a marked decrease in their antisubmarine and air activity, so much so that it was considered safe to send submarines on their working up patrols to the Norwegian coast. A total of eight submarines were sent out, half of which were on their first working up patrol. Sidon (Lieutenant HC Gowan RN) was the first away and patrolled off Andoy from 8th-23rd March but saw nothing. Stubborn (Lieutenant AG Davies RN) was next and was off Feje from 9th-18th also having a blank patrol. The veteran Venturer (Lieutenant JS Launders DSO DSC* RN) was out again, this time off Fro Havet, sailing on 14th. On the 19th, early in the morning, she attacked a convoy of four merchant ships with five escorts. She fired four torpedoes at a range of 6000 yards hitting and sinking Sirius of 918 tons. On 21st, she fired another four torpedoes at a merchant ship at 6000 yards, just after midday, but this time she missed. Dolfijn (Luitenant ter zee 1e Kl Maas) relieved Stubborn off Feje sailing on 17th. On the afternoon of 24th she sighted an inward bound U-boat but she was unable to get within range before the U-boat entered the leads. Utsira (Loytnant S Valvatne), Turpin (Lieutenant Commander JS Stevens DSO* DSC RN), Viking (Lieutenant R Bannar-Martin DSC RN) and Spearhead (Lieutenant Commander RE Youngman DSC RNR) left for patrol between 29th and 31st. Utsira made the last patrol of a Norwegian submarine in Home waters under British operational command. On the evening of 5th April she attacked a large convoy off Fro Havet firing four torpedoes at a range of 1300 yards, hitting and sinking Torridal of 1381 tons with three of them. She then suffered the last counter attack with depth charges in Home waters and, although there were no less than ten escorts, she was undamaged. Viking had a blank patrol off Egeroy but the new submarine Spearhead off Kors Fjord had contacts with U-boats on two occasions. At midday on 23rd March she saw a U-boat on the surface, but it dived almost at once and was not sighted again until it was inside Kors Fjord and no attack was possible. Three days later another U-boat traversed Spearhead's area without being detected and was only sighted when she surfaced inside Kors Fjord.

In April, four submarines crossed the North Sea to patrol off Norway. The brand new Totem (Lieutenant Commander MBSt John DSC RN) was off Kors Fjord from the 8th to the 19th April but saw nothing. The equally new Tapir (Lieutenant JCY Roxburgh DSO DSC RN) patrolled off Feje from 5th to 16th and on 12th April, early in the morning, heard the hydrophone effect of a U-boat on asdic. The U-boat then obligingly surfaced and Tapir fired six torpedoes at a range of 3200 yards, hitting and sinking U4865. This was the last success of the war by one of our submarines in Home waters. Venturer (Lieutenant JS Launders DSO DSC* RN) relieved Tapir off Kors Fjord and Varne (Lieutenant IG Raikes DSC RN) was sent to patrol off Skudenes. On 19th, intelligence suddenly came in that Prinz Eugen was northbound in the Sound. It had always been possible that the German Navy would attempt a final break out as they had contemplated doing in 1918.

Venturer was ordered to patrol off Egersund and Varne off Lister and other submarines in harbour were brought to short notice. On 21st, fresh intelligence revealed that Prinz Eugen was in harbour at Copenhagen and the panic died down. Most of the rest of the German heavy ships had by now been put out of action in German ports by Allied bombers and only Prinz Eugen and Nurnberg were fit for sea. Varne left patrol on 24th and Venturer next day. The hours of darkness were now becoming short, and no more patrols were ordered on the coast of Norway. The war was, in any case, nearly over. On the same day that Venturer left patrol, the American and Russian armies met on the Elbe and on 29th the German army in Italy surrendered. On 7th May, the Germans signed an instrument of unconditional surrender. This was in the nick of time. The first of the Type XXIII U-boats, U2336, sank two ships off the Firth of Forth on 6th May and a number of Type XXI U-boats were about to start operations.

With the German capitulation, the British submarine command was heavily involved in the surrender of the U-boats. The operation was under the overall direction of C-in-C, Western Approaches, but A(S) was required to provide inspection parties as well as for the care and administration of the U-boats once they had been surrendered. Planning for this operation had been in progress since Rear Admiral Creasy's return from the Far East in March. The surrendered U-boats were to be concentrated at Loch Ryan in Scotland and at Lisahally in Northern Ireland.

THE SUBMARINE CAMPAIGN IN HOME WATERS during the last seven months of the war in Europe was on a very small scale. There were never more than half a dozen operational submarines allocated to the area, and twenty-three of the patrols were made by new and refitted submarines working up and destined for the Far East. The fitting in of submarines with the operations of the Home Fleet and Coastal Command posed some problems. The weakness of the Luftwaffe and our good intelligence, which told us where the German minefields were, coupled with the fact that, at this time of year, there was no problem with constant daylight, meant that the opposition was far less than in former years. In fact not a single submarine was lost in this period, and only one was damaged and that was the Netherlands Dolfijn by an RAF aircraft. Altogether thirty-four patrols were made on the Norwegian coast in this period, eight of which were by submarines working up. They attacked five U-boats firing twenty torpedoes and sank U771, U864 and U486. They also attacked nineteen convoys sinking eight ships totalling 7841 tons and the escort vessels M132 and UJ1111. The four minefields laid by Rubis sank three ships of 14,627 tons and five minor warships and damaged another merchant ship of 1683 tons. The fifteen anti U-boat working up patrols round the Orkneys and Shetlands achieved nothing at all. When these results are compared with the results by other forces against enemy shipping, they seem small, but when added to them, they constituted a useful bonus6.

It is fair to comment that probably at least one more U-boat and several more ships would have been sunk but for the premature firing of the CCR pistol. It may seem odd that these pistols were tolerated for so long. However the CCR pistol had very great advantages. Not only was the damage done by an explosion under a ship much greater than a hit on the side, but it also allowed torpedoes to be run deeper. This meant that they could be fired in a rougher sea and the tracks would be less distinct. It also made it possible to attack shallow draught ships with success and also submerged U-boats. There was therefore reluctance to abandon it without very definite evidence that it was proving ineffective. It was not easy to be sure whether a CCR pistol had failed in a given attack, or had just missed. Prematures were not always seen, because the submarine was normally taking avoiding action to clear the torpedo tracks after firing, and would not be looking. In any case all new warheads were fitted with CCR pistols and the older types were out of production. The decision made at the end of 1944 to set all CCR pistols to contact only and to run them shallow to hit, was inevitable and the only way to ensure that they did not fire prematurely.

This book is really no place to speculate on what would have happened if the Germans had had time to deploy large numbers of Type XXI and Type XXIII U-boats at sea. We can merely note that if they had proved a serious menace, our submarines might well have been able to operate with some success against them. The attack by Venturer on U864 and the Tapir on U486, demonstrated that 'schnorchelling' U-boats could be detected and sunk by a submarine on patrol. It was probable that, had the war continued and the Type XXI become a serious menace, our submarines could have been developed and trained to be useful anti-submarine weapons against 'schnorchelling' U-boats on passage and their strength could have been greatly increased in Home waters for this purpose at the expense of the Far East.

In the New Year's Honours of 1945, Captain RS Warne, commanding the Third Submarine Flotilla, received the CBE, not only for the work of operational submarines under his command, but for bringing forward and working up a large number of new and refitted submarines. Lieutenant Launders of Venturer received the DSO for sinking U771 and a Bar for sinking U864. Lieutenant Westmacott of X24 also received a DSO for sinking the floating dock in Bergen. Capitaine de Corvette Henri Rousselot of Rubis was presented with a second Bar to his DSC when his submarine returned to France and ceased to be under British operational control. A bar to the DSC was awarded to Lieutenant Roxburgh of Tapir for sinking U486, an exploit that surely merited greater recognition. Finally Lieutenant McIntosh of Sceptre was Mentioned in Despatches for his patrols in September and October 1944, in which he sank four ships.
