In 1339, there had been discontent among the Genoese mercenaries hired by the French, whose commander had not been passing on their pay. Believing the fault lay with their French paymasters, a deputation sought an audience with the French king in August. The deputation was jailed, causing the Genoese crews to mutiny and return to the Mediterranean. When the mutinous sailors arrived back to Genoa, they led an uprising that overthrew the ruling patricians. The new regime was disinclined to enter into new contracts with the French. When several ship captains were persuaded to do so, they were bribed by English agents to renege. In January 1340 the English successfully raided the port of Boulogne, where the majority of the French galley fleet was drawn up on the harbour beach and was inadequately guarded. Taking advantage of a mist the English surprised the French and destroyed 18 galleys, 24 other ships, large stocks of naval equipment and much of the harbour district before being driven off. The French were left with only 6 galleys, which they supplemented with 22 oared barges.
