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.
Hundred Years' War (1337–1360)
In late October 1342, Edward III arrived with his main army at Brest, and retook Vannes. He then moved east to besiege Rennes. A French army marched to engage him, but a major battle was averted when two cardinals arrived from Avignon in January 1343 and enforced a general truce, the Truce of Malestroit. Even with the truce in place, the war continued in Brittany until May 1345 when Edward eventually succeeded in taking control.
