The ASC HT Companies in the Divisional Trains
Each Division of the army had a certain amount of transport under its own command, known as the Divisional Train. It was the ‘workhorse’ of the Division in terms of carrying stores and supplies, providing the main supply line to the transport of the brigades of infantry and artillery and other attached units. It initially comprised 26 officers and 402 other ranks of the Army Service Corps, looking after 378 horses, 17 carts, 125 wagons and 30 bicycles. These comprised a headquarters and 4 Horsed Transport Companies (one for each infantry Brigade and one for Divisional HQ and other troops). The Train moved with the Division. In all, there were 364 ASC Companies of this type.
