In World War II the Bridgwater and Taunton Canal formed part of the Taunton Stop Line, designed to prevent the advance of a German invasion. Pillboxes can still be seen along its length. The first bombs fell on Bridgwater on 24 August 1940, destroying houses on Old Taunton Road, and three men, three women and one child were killed. Later a prisoner of war camp was established at Colley Lane, holding Italian prisoners. During the preparations for the invasion of Europe, American troops were based in the town.
