[12] He transferred to the Medical Branch of the Royal Air Force on the formation of the new service on 1 April 1918[13]—taking a permanent commission as a flight lieutenant in 1920[14]—and ultimately reaching the rank of acting air vice marshal by 1945 when he was appointed Commander of the Order of the British Empire.

[2][15] The younger son, George Henry Fosbroke Power, died at the Second Battle of Ypres in 1915 when he was serving as a lieutenant in 6th Battalion, Middlesex Regiment.

After his home was damaged in an air raid in 1940, Power moved in with his son at 53 Murray Road, Northwood, Middlesex, where he died on 18 May 1941.
