6 Warnie had just begun thinking of entering the Army Service Corps, the one career he was always sure he wanted, while his father favoured a job with the London and North Western Railway.
The Army Service Corps, which supplied food, weapons and other necessities to the troops, began in 1794 as the Corps of Waggoners. Over time it evolved until in 1888 it was recreated the Army Service Corps. In 1918, in recognition of its good work, it became the Royal Army Service Corps. It was renamed the Royal Corps of Transport in 1965. See John Fortescue, The Royal Army Service Corps: A History of Transport and Supplies in the British Army, vol. I (1930). Volume II by R. H. Beadon was published in 1931.
