Hanbury-Tenison attended Eton and then served as an officer in the Irish Guards from 1943, firstly in Belgium and the Netherlands in late 1944 and then in Germany in 1945, where he was wounded.^[1]

He subsequently served in Romania and as political counsellor in Germany and Belgium. He left the service in 1975 and settled in the Welsh county of Gwent.
