Westport Battery (Harbour Mole Battery)

Westport was first defended by a pair of 12-pounder armoured gun trucks from 1910-1921. In 1942 a 5-inch US Naval gun was allocated to Westport. Construction began in June 1942 and the gun was mounted in July.

The battery went into Care and Maintenance in October 1943 and the gun was removed in August 1944.
