Philip VI of Valois: A New Dynasty, A War Begins (1328–1350) · HIGH MIDDLE AGES
After Crécy, England seeks a lasting foothold. The siege of Calais succeeds in 1347: the town becomes a major English stronghold on the coast, key for logistics, raids, and diplomatic pressure.
Calais controls direct access to the English Channel: supplies from England, troop movement, ties with Flemish allies. The town serves as a bridgehead, difficult to retake.
With Calais, war changes scale: it is no longer merely a succession of campaigns, but a lasting territorial presence. The French monarchy must now think reconquest, finances, and endurance.
