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.
Robert de Crull
The years of Crull's service as administrator of the navy (1359–78) were difficult ones for England. Edward III had achieved a succession of victories in France enabling him to secure great possessions. This had been another chapter in the ongoing Hundred Years War. His claim to the French throne seemed to be about to be realised. In 1359, he began a campaign to complete that undertaking. However, after a number of battles well into 1360 the outcome was still in doubt, and Edward was forced to accept the Treaty of Bretigny wherein he renounced his claim to the French throne so that he could secure full sovereignty of the possessions he had in France.
