of 1373 was successful, seeing, amongst other events, the burning of a Castilian merchant convoy at Saint-Malo. In retaliation, Fernando Sanchez de Tovar, who had succeeded Boccanegra as Major Admiral of Castile after his death in 1374, joined forces with the French admiral Jean de Vienne against England. Naval supremacy in the English channel, won in the battle of La Rochelle, allowed the allied fleet to plunder and burn the Isle of Wight and the English ports of Rye, Rottingdean, Winchelsea, Lewes, Folkestone, Plymouth, Portsmouth and Hastings between 1374 and 1380. Even an English army raised by the Earl of Arundel was defeated in a land battle at Lewes. In 1380 the joint fleet sailed up the Thames and burned Gravesend, over 20 miles east of London.
