October 31st, 1940
London and Alger - The Allied admiralty must face the facts: the pocket battleship Admiral Scheer disappeared between Stavanger and Bergen. It had certainly already managed to penetrate the screen of the British patrols and to pass in the Atlantic. Moreover, there are in Norway other German ships likely to come and play privateer - heavy cruisers, battlecruisers and, in a few months, the great battleship Bismarck itself will be ready to try the adventure. However, the Royal Navy lacks modern fast battleships; the King George V has just entered service and the Prince of Wales is not yet completed. The Italian threat seems to be under control for the time being, the French Admiralty agrees to deploy the battleship Richelieu, the heavy cruiser Algérie and the destroyers of the new 4th TD (Le Hardi, Casque, Epée and Fleuret) to Scapa Flow with the Home Fleet. To everyone's relief, Admiral Darlan, who had had the opportunity in early September, to state his opposition to this idea, declares himself in favor of it this time. To one of his collegues who was surprised by this, he replied: "But, my dear, now I am a minister!"
In addition, in application of the strategic orientations defined at the last Interallied council, the British Admiralty is reorganizing its forces. It plans to withdraw the battleships HMS Ramilies and Malaya from the eastern Mediterranean in November. In return, the Mediterranean Fleet will receive HMS Barham, so that the Allies, with at least three British battleships (Valiant, Warspite and Barham) and three French (Bretagne, Lorraine, Provence) [1] maintain a superiority of 2 to 1 against the Italian battleships.
As for the reinforcement of its forces in the Far East, the departure is decided in the short term of part of the Australian ships still engaged in the Eastern Mediterranean, namely the light cruiser HMAS Sydney and the destroyers Stuart and Vampire. The departure for the China Sea in January 1941 for the China Sea is decided for three of the large O class oceanic submarines, the Osiris, Otus and Otway. Of the two other surviving units, the Oswald, once repaired, will join Scotland for training with the 7th Flotilla, based at Holy Loch. The Olympus will remain in the Mediterranean for a few more months to compensate for the unavailability of the Perseus, under repair until April 1941. To cooperate with the French, the Royal Navy leaves the P [2] and R [3] class submarines, as well as the Rorqual.
For its part, the French Admiralty thoroughly revises its arrangements.
For the surface forces, in addition to the relocation of the Richelieu group, the favourable turn of events in the Mediterranean makes it possible to plan the next deployment to Gibraltar, in support of Force H, of the battlecruisers Dunkerque and Strasbourg. They are accompanied by the light cruisers Gloire, Georges-Leygues and Montcalm, as well as the destroyers of the 5th DCT, Chevalier-Paul, Tartu and Kersaint, all six of which are to be withdrawn from the eastern Mediterranean as soon as their presence is no longer required for Operation Accolade. It also authorizes the dispatch of several units in the Indian Ocean and Indochina, as well as, secondarily, in the Pacific, to counter the threat of German raiders. Eventually, a squadron will be formed in the China Sea, with three light cruisers [4] and eight destroyers. The avisos Amiral-Charner, D'Entrecasteaux, D'Iberville, Dumont-d'Urville and Bougainville are already sailing these distant seas. While waiting for the refurbishment of the large patrol boat Caraïbe (P6) [5], the auxiliary cruisers Aramis (X1), Victor-Schoelcher (X7) and Quercy (X20) will receive the reinforcement of its sister-ship, the Marigot (P1). The dispatch of two heavy cruisers was considered, but finally postponed. Indeed, the Regia Marina still has five units of this type [6]. However, the Royal Navy can only deploy one within the Mediterranean Fleet [7]. With the the Duquesne out of service for some time and the departure of the Algérie for Scapa Flow, the French Navy has only five or six cruisers left. That is just enough to obtain an Allied superiority of 6 to 5 for this category of ships.
After the end of its refit and modernization by an American shipyard, the Surcouf will stay in Martinique for some trials before joining the light cruiser Jeanne d'Arc (which went there after a short but active participation in Operation Marignan): for this purpose, it will use the Panama Canal [8].
The lesser tension in the Mediterranean has already allowed, at the end of Operation Marignan to send surface units to the Atlantic, notably the destroyers Albatros, Gerfaut, Vautour (7th DCT), which join their brothers of the Aigle [9] class, the Epervier, Milan and Aigle (11th DCT). They have also begun to reach the ocean, where they will patrol and escort convoys, along with the auxiliary cruisers that participated in operations Marignan and Cordite: the Colombie (X10), the three Els - El Djezaïr (X17), El Kantara (X16), El Mansour (X6) - while waiting for the Koutoubia (X4) and Ville d'Oran (X5) engaged in Accolade. All these redeployments free up the Casablanca and Dakar submarines, which were employed for a few months on futile patrols.
As for the submarine forces, the losses suffered since the beginning of the war lead the Admiralty to use an artifice to avoid reducing the number of submarine divisions. The Admiralty reduces the normal composition of the "1,500 ton" divisions from four to three units and the "1,100 ton" divisions from three to two units. Only the "600 ton" divisions remain for the time being composed, with some exceptions, of four vessels.
[1] Hypothesis taking into account the deployment in Gibraltar by the Marine Nationale of the Dunkerque and Strasbourg, which will be discussed below. Nevertheless, the two battlecruisers remain in a position to act in the Mediterranean.
[2] Pandora, Parthian, Perseus (in refit from October 1940 to April 1941), Proteus.
[3] Regent, Regulus, Rover.
[4] The Duguay-Trouin and Primauguet joining the Lamotte-Picquet to form a 6th Cruiser Division.
[5] Severely damaged in her fight on 7 October against the Italian auxiliary cruiser Ramb II.
[6] The Fiume was sunk at Taranto on August 24th, 1940. Raised, it will be in for many months of repairs. The Bolzano was more slightly damaged on September 6th by the submarine MN Pégase.
[7] Although none of the 15 heavy cruisers of the Royal Navy was sunk, 6 are unavailable due to damage inflicted by the enemy (Cumberland, Exeter, Kent) or major work in progress (London, Suffolk, Sussex).
[8] The treaties relating to the use of the canal allowed its crossing by armed vessels belonging to nations at war without violating the neutrality of the United States.
[9] As far as circumstances permit, these units will have their ASW capabilities upgraded, four depth charge launchers and two wake grenades replacing the 138 No. 5.piece.
