The city of Calais surrenders after a protracted siege to the English following the English defeat of a French relief fleet in the battle of Crotoy. It will remain in English hands for more than 200 years.

Calais is a French major port city in the Pas-de-Calais department, of which it is a subprefecture. Calais is the largest city in Pas-de-Calais. The population of the city proper is 67,585; that of the urban area is 144,488 (2022). Calais overlooks the Strait of Dover, the narrowest point in the English Channel, which is only 34 km (21 mi) wide here, and is the closest French town to England. The White Cliffs of Dover can easily be seen from Calais on a clear day. Calais is a major port for ferries between France and England. The Channel Tunnel has connected Calais and Folkestone since 1994.
