As the opening phase of Operation Catapult, the French squadron at Alexandria in Egypt was dealt-with via negotiations. This proved possible primarily because the two commanders—Admirals René-Emile Godfroy and Andrew Cunningham—were on good personal terms. In contrast, a British ultimatum to place the bulk of the remainder of the French fleet out of German reach was refused. The fleet was located at Mers-el-Kebir in Algeria, so on 3 July 1940 it was largely destroyed by bombardment by the British "Force H" from Gibraltar (Admiral James Somerville). The Vichy French government broke off all ties with the British as a result of this attack and the Vichy French Air Force ("Armée de l'Air de Vichy") even raided British installations at Gibraltar.
