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.
Chevauchée
The chevauchée has gained recognition for its use during the Hundred Years' War between the Kingdom of England and the Kingdom of France. It was not a new tactic and had been used many times before; for example, William the Conqueror had used the tactic before the Battle of Hastings to encourage Harold to engage in a battle. The difference was that during the Hundred Years' War the tactic was used more frequently, on a larger scale and more systematically than before.
