In November 1349, Charles de la Cerda, a soldier of fortune, son of Luis de la Cerda, and member of a branch of the Castilian royal family, sailed from northern Spain, commissioned by the French, with an unknown number of ships. He intercepted and captured several English ships laden with wine from Bordeaux and murdered their crews. Later in the year de la Cerda led a Castilian fleet of 47 ships loaded with Spanish wool from Corunna to Sluys, in Flanders, where it wintered. On the way he captured several additional English ships, again throwing the crews overboard.
