Force H was a British naval formation during the Second World War. It was formed in late-June 1940, to replace French naval power in the western Mediterranean removed by the French armistice with Nazi Germany. The force occupied an odd place within the naval chain of command. Normal British practice was to have naval stations and fleets around the world, whose commanders reported to the First Sea Lord via a flag officer. Force H was based at Gibraltar but there was already a flag officer at the base, Flag Officer Commanding, North Atlantic. The commanding officer of Force H did not report to this Flag Officer but directly to the First Sea Lord, Admiral of the Fleet Sir Dudley Pound.

Hunt for the Admiral Graf Spee

[edit]

In anticipation of the outbreak of Word War 2 on 3 September 1939 the German Kriegsmarine had already deployed the two heavy cruisers Admiral Graf Spee and Deutschland as commerce raiders in the North and South Atlantic. When these ships started operating against British and French ships in October 1939, the British and French navy responded by forming eight hunting groups, named Force F, G, H, I and Force K, L, M and N. These forces were composed of cruisers, fast battlecruisers and airplane carriers. Force H was stationed in Cape of Good Hope and was composed of the British heavy cruisers Sussex and Shropshire. By December 1939 Deutschland had returned to German port and the Admiral Graf Spee was found by Force G, damaged in the Battle of the River Plate and subsequently scuttled at Montevideo. With the threat of German raiders gone, the hunting groups were disbanded and Force H ceased to exist.[1]

Operation Catapult

[edit]
Main article: Attack on Mers-el-Kébir

The surrender of France created a void in the Western Mediterranean. On 27 June Vice admiral James Somerville was appointed as commander of Force H stationed In Gibraltar. It was an independend command directly responsible to the Admiralty in London. The first operation that Force H took part in was connected with the reason for its formation. French naval power still existed in the Mediterranean, and the British Government viewed it as a threat to British interests. It was feared that the Vichy government of Philippe Pétain would hand the ships over to Germany, despite a vow that that would never happen. This would almost certainly tip the balance decisively against Britain in the Mediterranean. Consequently, Force H was ordered to execute Operation Catapult.[2]

The most powerful of the remaining French forces was in port at Mers-el-Kébir in Algeria. It consisted of the French battleships Strasbourg, Dunkerque, Bretagne and Provence, and six destryers. Force H steamed to off the Algerian coast, and an envoy was sent to the French commander. Various terms were offered, including internment of the fleet in a neutral country, joining the British forces, or scuttling the fleet at its berths.[3] However, the commander of the French forces reported only the scuttling option to his superiors, and was consequently ordered to fight the British. The reasons for the omission have been debated by many. It is often thought that the anti-British bias of the French commander was to blame.[citation needed] The result of the action was that Dunkerque and Provence were damaged and put out of action, Bretagne was destroyed with heavy loss of life, but Strasbourg and four destroyers could escape to Toulon, a French base on the Mediterranean coast of metropolitan France.[4]

Convoy operations

[edit]
Main article: Malta Convoys

After this unpleasant operation, Force H settled down to its more normal operations. These involved general naval tasks in the western basin of the Mediterranean. Prominent amongst these tasks was fighting convoys through to Malta. The early convoys came through with relatively light losses. That changed in 1941, when the Germans sent the Luftwaffe's X. Fliegerkorps to Sicily; its bombers took a high toll of both warships and merchantmen. Also, from 1942 the improved combat efficiency of the Regia Aeronautica (and especially of its SM.79 torpedo bombers) and of the Regia Marina's submarines posed a far greater threat to these convoys than the 1940 Italian opposition.

In November 1940, screening convoys to Malta, Force H made an important contribution to Operation MB8, and the resulting success of Operation Judgement, the attack on Taranto harbour.[5]

"Sink the Bismarck!"

[edit]
Main articles: Battle of the Denmark Strait and Last battle of the battleship Bismarck

The most famous incident involving Force H in 1941 did not occur in the Mediterranean, but in the Atlantic Ocean. The German battleship Bismarck had sailed in company with the heavy cruiser Prinz Eugen to attack commercial shipping. She went far to the north of the UK, passing southwest through the Denmark Strait between Iceland and Greenland. There, she was intercepted by a British force made up of the battleship Prince of Wales and the battlecruiser Hood. The engagement was a disaster for the Royal Navy; Prince of Wales was damaged and Hood's magazine exploded, breaking the ship in half. Only three out of 1,418 crew aboard were rescued from the sinking. Every Royal Navy unit available was then given the task of destroying Bismarck.

Force H set sail from Gibraltar to intercept Bismarck with the aircraft carrier Ark Royal, the battlecruiser Renown and the light cruiser Sheffield. Bismarck had not come out of the Denmark Strait engagement completely unscathed: a shell from Prince of Wales had ruptured the ship's fuel tanks, causing her to lose oil. The commerce-raiding cruise was thus cut short, and the ship headed for the port of Brest in occupied France. Bismarck was temporarily lost to the Royal Navy after she evaded the radar of the shadowing cruisers Suffolk and Norfolk. She was found again, but the only way of stopping her was if something slowed the ship down. To try to do this, Ark Royal launched a strike with her Fairey Swordfish torpedo bombers. However, the aircrews were wrongly informed of the location of Sheffield and attacked her instead, mistaking her for Bismarck. The torpedoes that the Swordfish had dropped carried a new type of magnetic detonator which proved too unreliable. A second strike was flown carrying the older, and more reliable, contact detonator. Bismarck was found and a torpedo jammed her steering gear. Unable to evade the British ships closing in, the German battleship was scuttled following incapacitating battle damage dealt by a force including King George V and Rodney.

Britain at rock bottom

[edit]

The end of 1941 saw the nadir of British naval fortunes in the Mediterranean. The Mediterranean Fleet lost the services of HMS Illustrious to bomb damage, HMS Barham was sunk off Crete by U-331, and its two remaining battleships were put out of action by an Italian raid on Alexandria. Force H in its turn suffered as well: Ark Royal was sunk by U-81 in November 1941. It was only the lack of action by the Italians that prevented a complete disaster for British fortunes. The most urgent task during the first part of the year was supplying Malta. The island had been under heavy attack for many months and supply convoys had to be escorted by many ships and aircraft to stand any chance of getting through. Malta was kept from starving but it was very close. Operation Pedestal, the most escorted convoy in the Second World War, delivered enough supplies in August to keep Malta going.

Amphibious assaults and the end of Force H

[edit]

Force H was not actually extant for a portion of 1942. It was stripped bare in May to provide ships for the assault on Vichy French forces at Diego Suarez in Madagascar during Operation Ironclad. This operation succeeded, but many[who?] argue that it was a waste of British naval resources at a critical time in the war.

November saw the turning point of the conflict. Operation Torch saw British and American forces landed in Morocco and Algeria under the British First Army. Force H was reinforced to cover these landings. The two main threats were the Italian fleet and French forces. In the end, only French forces fought, and the most significant battles took place at Casablanca where only American naval units supported the operations.

The end of the campaign in North Africa saw an interdiction effort on a vast scale. The aim was to cut Tunisia completely off from Axis support. It succeeded, and 250,000 men surrendered to the 18th Army Group, a number equal to those who surrendered at Stalingrad. Force H again provided heavy cover for this operation.

Two further sets of landings were covered by Force H against interference from the Italian fleet. Operation Husky in July 1943 saw the invasion and conquest of Sicily, and Operation Avalanche saw an attack on the Italian mainland at Salerno.

Following the Allied landings on Italy itself, the Italian government surrendered. The Italian fleet mostly escaped German capture and much of it formed the Italian Co-Belligerent Navy. However, two German Fritz X radio-controlled missiles did hit and sink the battleship Roma, killing the Commander-in-Chief of the Italian Royal Navy (Regia Marina), Admiral Carlo Bergamini.

With the surrender of the Italian fleet, the need for heavy units in the Mediterranean disappeared. The battleships and aircraft carriers of Force H dispersed to the Home and Eastern Fleets and the command was disbanded. Naval operations in the Mediterranean from now on would be conducted by lighter units.
