Merchant shipping was an essential part of the war effort and their convoys carried vital supplies around the world to support our troops. Besides the protection offered by the Royal Navy escorts, the merchant ships were equipped with guns to deter airborne attacks. They were known as Defensively Equipped Merchant Ships.
The Maritime Royal Artillery was established in March 1940 when the Royal Navy was short of gunners to man the defensive armament on merchant ships working costal routes on the south and east coasts of England. The regiment started in Thornbury and was also disbanded in Thornbury with the rest of the maritime regiments in 1946. Initially, the Admiralty requested the regiment to provide 500 two-man light machine gun teams for the merchant coasters so originally 940 army personnel volunteered armed with Lewis or Bren guns to provide anti-aircraft defence for the vessels.
