Edward III was the first English king to have a claim to the throne of France. His pursuit of the claim resulted in the Hundred Years' War (1337–1453), which pitted five kings of England of the House of Plantagenet against five kings of France of the Capetian House of Valois. Extensive naval raiding was carried out by all sides during the war, often involving privateers such as John Hawley of Dartmouth or the Castilian Pero Niño. Though the English won numerous victories, they were unable to overcome the numerical superiority of the French and their strategic use of gunpowder weapons. England was defeated at the Battle of Formigny in 1450 and finally at the Battle of Castillon in 1453, retaining only a single town in France, Calais.
