intelligence that had indicated that the Germans would attempt to force a group of battleships through the Strait of Gibraltar to strengthen the Italian fleet. After the French fleet got underway, reconnaissance aircraft reported spotting an enemy fleet steaming toward Gibraltar. Supposing the aircraft to have spotted the Italian battle fleet steaming to join the Germans, the French increased speed to intercept them, only to realize that the aircraft had in fact located the French fleet. The fleet then returned to port, marking the end of Strasbourgs last wartime operation. On 22 June, France surrendered to Germany following the Battle of France. Under the terms of the Armistice, Strasbourg and Dunkerque would remain at Mers-el-Kébir. Mers-el-Kébir The only test in battle for Strasbourg came in the attack on Mers-el-Kébir on 3 July. The British, misinterpreting the terms of the armistice as providing the Germans with access to the French fleet, feared that the ships would be seized and pressed into service against them despite assurances from François Darlan, the Chief of the Naval General Staff, that if the Germans attempted to take the vessels, their crews would scuttle them. Prime Minister Winston Churchill then convinced the War Cabinet that the fleet must be neutralized or forced to re-join the war on the side of Britain. The British Force H, commanded by Admiral James Somerville and centered on the battlecruiser and the battleships , and , arrived off Mers-el-Kébir to coerce the French battleship squadron to join the British cause or scuttle their ships. The French Navy refused, as complying with the demand would have violated the armistice signed with Germany. To ensure the ships would not fall into Axis hands, the British warships opened fire at 17:55. Strasbourg was tied alongside the mole with her stern facing the sea, so she could not return fire. Immediately after the British started shooting, Gensoul issued the order to get underway and return fire. Strasbourg, at that time commanded by Capitaine de vaisseau (Ship of the line captain) Collinet, was the first large warship to slip her mooring, following four destroyers on their way out of the harbor. Debris from near misses showered the ship as she made her way through the port; some of these fragments dented or punched holes in her hull, and burning debris scorched her deck. A salvo of shells near-missed the ship at 18:00. As the vessels cleared
