Lieutenant General Snow retired from the army in September 1919. He was appointed Colonel of the Suffolk Regiment in October 1918 but exchanged that distinction for the colonelcy of his own old regiment, the Somerset Light Infantry. This he held for ten years until 1929.
Snow had suffered a serious hip injury when he fell from his horse during the Battle of the Aisne in September 1914. He remained a cripple to his death and in his later years became largely confined to a wheelchair. Yet, he never lost his good spirits and was always excellent company. Much of his time in later years was devoted to charitable works. He became chairman of the National Institute for Crippled Boys in Kensington, established in 1865 to provide boarding, clothing and education to destitute, neglected or ill-used crippled boys between the ages of twelve and eighteen. The building in which the institute was housed was inconvenienced by a large coal depot which had been constructed nearby on surplus railway land. One of Snow’s last activities was the planning of the removal of the institution to a more suitable site outside London. He died at his home in Kensington Gate, London on 30 August 1940, aged 82.
