CAREY’S FORCE.—During the Second Battle of the Somme “a mixed force, including details, stragglers, schools personnel, tunnelling companies, army troops companies, field survey companies, and Canadian and American Engineers, had been got together and organised by Major-Gen. P. G. Grant, the Chief Engineer to the V. Army. On March 26 these were posted by General Grant, in accordance with orders given by the V. Army commander, on the line of the old Amiens defences between Mezières, Marcelcave, and Hamel. Subsequently, as General Grant could ill be spared from his proper duties, he was directed to hand over command of his force to Major-Gen. G. G. S. Carey. Except for General Carey’s force there were no reinforcements of any kind behind the divisions, which had been fighting for the most part since the opening of the battle.... On March 28 our line from Marcelcave to the Somme was manned by Carey’s Force, with the 1st Cavalry Division in close support.... On March 29 the greater part of the British front south of the Somme was held by Carey’s Force, assisted by the 1st Cavalry Division and such troops of the divisions originally engaged as it had not yet been found possible to withdraw. In rear of these troops, a few of the divisions of the V. Army were given a brief opportunity to reassemble” (Sir D. Haig’s Dispatches).
