Trench Mortar Batteries and Groups Introduction Each division had a trench mortar group, which was composed of one heavy battery and three medium batteries. Each infantry brigade had a light trench mortar battery which contained eight mortars organized into four batteries. A GHQ letter of 15 December 1915 authorized the formation of two light trench mortar batteries in each brigade. Another GHQ letter (9 September 1916) authorized that the two brigade batteries be combined, taking the brigade number for the new battery designation (RG 9 III, vol. 4339, folder 6, file 4). The establishment apparently consisted of the officer commanding, four section officers and 60 other ranks. 1
