units and the Royal Engineers Fortress Company were withdrawn, with their roles taken up respectively by the BMA and the new Bermuda Volunteer Engineers (BVE), raised in 1931. The coastal artillery forts and batteries were all mothballed or permanently removed from use except for St. David's Battery, which continued in the role of Examination Battery, watching over the channel through which shipping passed through Bermuda's surrounding barrier reef. The regular army infantry battalion was replaced by a company detached from whatever battalion was deployed to Jamaica (the unit on garrison continued to be replaced every three years). This consequently increased the requirement for part-time infantrymen. As the manpower requirements of the artillery had been reduced with the closure of most of the batteries, a new unit, the Bermuda Militia Infantry, was raised, grouped administratively with the BMA and likewise recruiting black soldiers, in 1939. That year, with war imminent, a new coastal artillery battery, with two 6 inch RBL guns, was built on a hill within Warwick Camp, intended to prevent naval vessels from bombarding the Royal Naval Dockyard from off Bermuda's South Shore. As with St. David's Battery, the guns were manned by the BMA and the Defence Electric Lights by the BVE. Second World War During the Second World War, as had been the case during the First World War, the units posted to Bermuda to provide the regular infantry company on garrison included reserve units from the Canadian Army (as the Canadian Militia had been renamed in 1940), embodied for the duration of the war. At the start of the war a company of the 2nd Battalion, King's Shropshire Light Infantry was on deployment to Bermuda. They were succeeded by the Canadian Army's Winnipeg Grenadiers in 1940, a company of the 4th Battalion, Queen's Own Cameron Highlanders (including future Major Donald Henry "Bob" Burns, MC, who would be a Second-in-Command of the Bermuda Regiment, Town Crier of St. George's, and Guinness world record holder for loudest human speaking voice) in 1942, and a company of the Canadian Pictou Highlanders from 1942 to 1946. As during the First World War, the part-time units were again mobilized for the duration (The Bermuda Militia Artillery and the Bermuda Volunteer Engineers at mid-day on 24 August 1939, in anticipation of the 1 September invasion of Poland by Germany, and preparatory to the 3 September declaration of war against Germany, with the
