Hitchcock was too young to enlist when the First World War started in July 1914, and when he reached the required age of 18 in 1917, he received a C3 classification (“free from serious organic disease, able to stand service conditions in garrisons at home … only suitable for sedentary work”).[37] He joined a cadet regiment of the Royal Engineers and took part in theoretical briefings, weekend drills and exercises.
