Hundred Years' War
Historians commonly divide the war into three phases separated by truces: the Edwardian War (1337–1360), the Caroline War (1369–1389), and the Lancastrian War (1415–1453). Local conflicts in neighbouring areas, which were contemporarily related to the war, including the War of the Breton Succession (1341–1365), the Castilian Civil War (1366–1369), the War of the Two Peters (1356–1369) in Aragon, and the 1383–85 crisis in Portugal, were availed by the parties to advance their agendas. Later historians adopted the term "Hundred Years' War" as a historiographical periodisation to encompass all of these events, thus constructing the longest military conflict in European history.
Hundred Years' War
The Battle of Crécy was a complete disaster for the French, largely credited to the longbowmen and the French king, who allowed his army to attack before it was ready. Philip appealed to his Scottish allies to help with a diversionary attack on England. King David II of Scotland responded by invading northern England, but his army was defeated and he was captured at the Battle of Neville's Cross, on 17 October 1346. This greatly reduced the threat from Scotland. In France, Edward proceeded north unopposed and besieged the city of Calais on the English Channel, capturing it in 1347. This became an important strategic asset for the English, allowing them to safely keep troops in northern France. Calais would remain under English control, even after the end of the Hundred Years' War, until the successful French siege in 1558.
