An emergency battery of two 12-pounder guns emplaced in August 1940, one on each of the inner pier heads. Initially B Battery, 509 Coast Regt; later 265 Coast Battery RA. This was a difficult command due to the need to detour several miles through Sunderland to get from No. 1 Gun on the north pier to No.
2 Gun on the south pier. Despite this, during a 1941 tour of inspection, it is described as a good battery with a note that it lacked a command post and overhead covers. Placed in care and maintenance in April 1944, abandoned December 1944.
