The Battle of Calais took place in 1350 when an English force defeated an unsuspecting French army which was attempting to take the city. Despite a truce being in effect the French commander Geoffrey de Charny had planned to take the city by subterfuge, and bribed Amerigo of Pavia, an Italian officer of the city garrison, to open a gate for them. The English king, Edward III, became aware of the plot and personally led his household knights and the Calais garrison in a surprise counter-attack. The French were routed by this smaller force, with significant losses and all their leaders captured or killed.
