During the Hundred Years' War in 1360, following the Treaty of Brétigny La Rochelle again came under the rule of the English monarch. La Rochelle however expelled the English in June 1372, following the naval Battle of La Rochelle, between Castilian-French and English fleets. The French and Spanish decisively defeated the English, securing French control of the Channel for the first time since the Battle of Sluys in 1340. The naval battle of La Rochelle was one of the first cases of the use of handguns on warships, which were deployed by the French and Spanish against the English. Having recovered freedom, La Rochelle refused entry to Du Guesclin, until Charles V recognized the privileges of the city in November 1372.
