The 1759 invasion preparations expose the port’s central weakness. Brest stood on a relatively infertile peninsula and depended on coastal shipping for food, timber, and raw materials. A large army therefore could not simply be assembled beside the fleet, forcing France to gather troops and transports farther south around Vannes and the Gulf of Morbihan. Blockade attacked the sustaining system behind French naval power as well as the warships themselves.
