Royal Navy in 1939 - The Allies primary maritime tasks were based on the assumption Britain and France would go to war against the European Axis powers of Germany and Italy. The Royal Navy would be responsible for the North Sea and most of the Atlantic, although the French would contribute some forces. In the Mediterranean, defence would be shared between both Navies The Royal Navy, still the largest in the world in September 1939, included 60 submarines, mainly modern with nine building. They were reasonably well-equipped with effective guns, torpedoes and fire control. Approximately 21 were based in Home waters and four in the Atlantic. The main defined role for the Home Fleet submarines appears to be patrolling off southwest Norway and the German North Sea bases for surface raiders and U-boats on passage.

1939-45 - As the war progressed, the Royal Navy and its few Allied-manned submarines neither had the target opportunities of the German U-boats in the Atlantic Ocean nor the US submarines in the Pacific, and certainly in the early years suffered heavy losses for comparatively few gains at least in Axis warships. Yet once account is taken of such vital activities as the heavy merchant ship sinkings in the Mediterranean, certainly in the battle for North Africa, the many dangerous cloak-and-dagger operations so vital to Churchill's command to "set Europe alight", helping to cut Germany supply routes from Norway and Japanese ones to Burma, then the even more silent part of the "Silent Service" played a major role in clearing the seas of Axis shipping. The figures for merchant ship sinkings by British submarines are not complete but give some idea of their successes.


HM Submarine Storm

Perhaps one example would suffice to illustrate these otherwise cold statistics - HMS Storm, the first British submarine commanded by a RNVR officer, Commander Edward Young DSO, DSC RNV(S)R. After twelve months from January 1944 to January 1945 on patrol in the SE Asia area, his "Jolly Roger" recorded three torpedo sinkings, seven gunnery sinkings, one cloak-and-dagger special operation, and "the little schooner surmounting a row of dots ... for indicating the results of the Celebes patrol". He prefaces these comments by writing that "Storm's Jolly Roger boasted a small bag compared with those of many other, more famous submarines". ("One of Our Submarines" by Edward Young, 1953)

8th - On the last day of the Norwegian campaign the Polish “ORZEL” on passage to her patrol area and made famous after escaping from invaded Poland, was presumed mined. Another Allied boat was lost twelve days later.

20th - Dutch submarine “0-13” also on passage to her Norwegian patrol area was torpedoed in error by Polish “Wilk”. More recent research suggests she was more likely sunk 13 June 1940 in a German minefield in 5655'N-0340'E.

20th - As the damaged battlecruiser “Scharnhorst” headed for Germany from Norway, “Gneisenau” feinted towards Iceland. West of Trondheim she was torpedoed and damaged by British submarine “Clyde”. Both battlecruisers were out of action during the critical phases of the Battle for Britain until the end of the year.

Mediterranean

Italy Declared War - Italy declared war on Britain and France on the 10th. Two weeks later France was out of the war. Still on the 10th, Australia, Canada, India, New Zealand and South Africa declared war on Italy. The Royal Navy started with ten submarines based in the Eastern Mediterranean.

13th - Mediterranean Fleet submarines operated out of Alexandria on patrol off Italian bases and soon lost three of their number (1-3). At the time mines were usually blamed, but it turns out Italian anti-submarine forces were far more effective than expected. The first loss was “ODIN” (1) off the Italian coast in the Gulf of Taranto, sunk by the guns and torpedoed of destroyer “Strale”.

16th - The second British submarine “GRAMPUS” (2), minelaying off Augusta, Sicily was caught and sunk by large torpedo boats “Circe” and “Clio”.

Malta - By now Malta had almost ceased to be of any value as a base for attacking Rommel's supply lines, and most of his transports were getting through. The German and Italian bombing led to the loss, directly and indirectly, of numerous ships including four destroyers and four submarines: 1st - Submarines "P-36" and "PANDORA" were sunk in Malta and others of the 10th Flotilla damaged. "Pandora" had only recently arrived from Gibraltar on a supply trip. 4th - Greek submarine "GLAVKOS" was sunk in Malta. 14th - 10th Flotilla lost its most famous boat when "UPHOLDER" (Lt-Cdr Wanklyn VC) went missing. She attacked a convoy northeast of Tripoli and was presumed sunk in the counter-attack by destroyer escort "Pegaso". 27th - By this time the 10th Submarine Flotilla had been ordered to leave Malta. "URGE" sailed for Alexandria on the 27th, but failed to arrive.

Russian Convoy PQ18 - PQ18 left Loch Ewe in Scotland on the 2nd with over 40 merchantmen. Close escort was provided by 17 warships plus escort carrier "Avenger" and two destroyers. Two separate forces were in support - close cover was given by AA cruiser "Scylla" and 16 fleet destroyers and further out three heavy cruisers. More distant cover was by battleships "Anson" and "Duke of York", a light cruiser and destroyers to the northeast of Iceland. Home Fleet submarines were on patrol off the Norwegian Lofoten Islands and northern Norway. Of the original 40 ships, 27 reached Archangel on the 17th in exchange for three U-boats.

Mediterranean

Mid-September - Submarine "TALISMAN" left Gibraltar on the 10th with stores for Malta. She reported a U-boat off Philippeville, eastern Algeria on the 15th, but was not heard from again - presumed mined in the Strait of Sicily.

Early October - Submarine "UNIQUE" on passage from Britain to Gibraltar was last reported on the 9th off Land's End, south west England. She was never heard from again.

Mediterranean

French North Africa - In preparation for Operation 'Torch', US Gen Mark Clark landed in Algeria from submarine "Seraph" to help persuade the Vichy French authorities to support the coming Allied landings. Gen Giraud was to be smuggled from unoccupied France, again in "Seraph", to head pro-Allied Frenchmen.

19th - South of Pantelleria, submarine "Unbending" attacked an Axis convoy bound for Tripoli, sinking a transport and Italian destroyer "DA VERAZZANO".

North Africa - With the Second Battle of El Alamein, Gen Montgomery started the last and decisive British campaign against Axis forces in Egypt.

Since Operation 'Excess' in January 1941, two aircraft carriers, four cruisers, 16 destroyers and five submarines had been lost in the many attempts to supply and reinforce the island, and in the heavy air attacks launched against the George Cross island.

24th - Off northwest Sicily, "UTMOST" was lost to Italian destroyer escort "Groppo".

DECEMBER 1942
