79 Years Ago Today; Royal Navy bombs French fleet at Mers-el-Kbir; 1297 French sailors killed

The Attack on Mers-el-Kébir (3 July 1940) also known as the Battle of Mers-el-Kébir, was part of Operation Catapult. The operation was a British naval attack on French Navy ships at the base at Mers El Kébir on the coast of French Algeria. The bombardment killed 1,297 French servicemen, sank a battleship and damaged five ships, for a British loss of five aircraft shot down and two crewmen killed.

The attack by air-and-sea was conducted by the Royal Navy after France had signed armistices with Germany and Italy that came into effect on 25 June. Of particular significance to the British were the seven battleships of the Bretagne, Dunkerque and Richelieu classes, the second largest force of capital ships in Europe after the Royal Navy. The British War Cabinet feared already that France would hand the ships to the Kriegsmarine, giving the Axis assistance in the Battle of the Atlantic or Battle of the Mediterranean. Admiral François Darlan, commander of the French Navy, promised the British that the fleet would remain under French control but Winston Churchill and the War Cabinet judged that the fleet was too powerful to risk an Axis take-over.

After the attack at Mers-el-Kébir and the Battle of Dakar, French aircraft raided Gibraltar in retaliation and the Vichy government severed diplomatic relations with the United Kingdom. The attack created much rancour between France and Britain but also demonstrated to the world that Britain intended to fight on. The attack is controversial and the motives of the British are debated. In 1979, P. M. H. Bell wrote that "The times were desperate; invasion seemed imminent; and the British government simply could not afford to risk the Germans seizing control of the French fleet... The predominant British motive was thus dire necessity and self-preservation".

The French thought they were acting honourably in terms of their armistice with Nazi Germany and were convinced they would never turn over their fleet to Germany. Vichy France was created on 10 July 1940, a week after the attack and was seen by the British as a puppet state of the Nazi regime. French grievances festered for years over what they considered a betrayal by their ally. On 27 November 1942, the scuttling of the French fleet in Toulon foiled Operation Anton, a German attempt to capture the rest of the French fleet after the Allied invasion of Morocco and French Algeria in Operation Torch.

Ultimatum
The most powerful group of French warships was at Mers-el-Kébir in French Algeria, consisting of the old battleships Provence and Bretagne, the newer Force de Raid battleships Dunkerque and Strasbourg, the seaplane tender Commandant Teste and six destroyers under the command of Admiral Marcel-Bruno Gensoul. Admiral James Somerville of Force H, based in Gibraltar, was ordered to deliver an ultimatum to the French but the British terms were contrary to the German-French armistice terms. Somerville passed the duty of presenting the ultimatum to a French speaker, Captain Cedric Holland, commander of the carrier HMS Ark Royal. Gensoul was affronted that negotiations were not being conducted by a senior officer and sent his lieutenant, Bernard Dufay, which led to much delay and confusion. As negotiations dragged on, it became clear that neither side was likely to give way. Darlan was at home on 3 July and could not be contacted; Gensoul told the French government that the alternatives were internment or battle but omitted the option of sailing to the French West Indies. Removing the fleet to United States waters had formed part of the orders given by Darlan to Gensoul in the event that a foreign power should attempt to seize his ships.

Attack

The British force comprised the battlecruiser HMS Hood, the battleships HMS Valiant and Resolution, the aircraft carrier Ark Royal and an escort of cruisers and destroyers. The British had the advantage of being able to manoeuvre, while the French fleet was anchored in a narrow harbour and its crews did not expect an attack. The main armament of Dunkerque and Strasbourg was grouped on their bows and could not immediately be brought to bear. The British capital ships had 15-inch (381 mm) guns and fired a heavier broadside than the French. On 3 July, before negotiations were formally terminated, British Fairey Swordfish planes escorted by Blackburn Skuas from Ark Royal dropped magnetic mines in the harbour exit. The force was intercepted by French Curtiss H-75 fighters and a Skua was shot down into the sea with the loss of its two crew, the only British fatalities in the action.[16] French warships were ordered from Algiers and Toulon as reinforcements but did not reach Mers-El-Kebir in time to affect the outcome.[8]

A short while later, at 5:54 p.m., Churchill ordered the British ships to open fire against the French ships and the British commenced from 17,500 yd (9.9 mi; 16.0 km). The third British salvo scored hits and caused a magazine explosion aboard Bretagne, which sank with 977 of her crew at 6:09 p.m. After thirty salvoes, the French ships stopped firing; the British force altered course to avoid return fire from the French coastal forts but Provence, Dunkerque and the destroyer Mogador were damaged and run aground by their crews. Strasbourg and four destroyers managed to avoid the magnetic mines and escape to the open sea under attack from a flight of bomb-armed Swordfish from Ark Royal. The French ships responded with anti-aircraft fire and shot down two Swordfish, the crews being rescued by the destroyer HMS Wrestler. As the bombing had little effect, at 6:43 p.m. Somerville ordered his forces to pursue and the light cruisers HMS Arethusa and Enterprise engaged a French destroyer. At 8:20 p.m. Somerville called off the pursuit, feeling that his ships were ill deployed for a night engagement. After another ineffective Swordfish attack at 8:55 p.m., Strasbourg reached Toulon on 4 July.

On 4 July, the British submarine HMS Pandora sank the French aviso (gunboat) Rigault de Genouilly, sailing from Oran, with the loss of 12 of its crew. As the British believed that the damage inflicted on Dunkerque and Provence was not serious, Swordfish aircraft from Ark Royal raided Mers-el-Kébir again on the morning of 8 July. A torpedo hit the patrol boat Terre-Neuve, which was full of depth charges and moored alongside Dunkerque. Terre-Neuve quickly sank and the depth charges went off, causing serious damage to Dunkerque. The last phase of Operation Catapult was another attack on 8 July, by aircraft from the carrier HMS Hermes against the battleship Richelieu at Dakar, which was seriously damaged. The French Air Force (Armée de l'Air) made reprisal raids on Gibraltar, including a half-hearted night attack on 5 July, when many bombs landed in the sea and raids on 24 September by forty aircraft and the next day with more than a hundred bombers.
