04/03/1941 Platoon locality - D Coy. Cassini ref. 858615. (See also UORNs 5172, 2041, and 16286). A report on the reorganisation of the defences here in March 1941 states there are two posts on the sea wall which must be loopholed for flanking fire, and with a part-breastwork to cover the rear.
The existing wire was to be brought closer in and its apron and concertina wire thickened. Knife rests were set up on the road and track. The defence locality acted as local protection for the 6in guns of the adjacent battery. Accommodation for the platoon was at the Marine Inn.
