Hundred Years' War (1415–53)
The Lancastrian War was the third and final phase of the Anglo-French Hundred Years' War. It lasted from 1415, when King Henry V of England invaded Normandy, to 1453, when the English lost Bordeaux. It followed a long period of peace from the end of the Caroline War in 1389. The phase was named after the House of Lancaster, the ruling house of the Kingdom of England, to which Henry V belonged.
Truce of Espléchin
The Hundred Years' War had started in 1337. In 1340 Edward III of England, returned to France by sailing across the English Channel only to find his landing blocked by a large French and Genoese fleet at Sluys. The English won the resulting naval battle, which took place on 24 June 1340. The English navy was ably assisted by their allies, principally Flemings from Sluys and nearby Bruges who watched the fight from the shore and kept any French sailors from escaping.
