Fox was commissioned into the Oxfordshire and Buckinghamshire Light Infantry in April 1941 and was posted to the 7th Ox and Bucks.

When Fox was asked by Sweeney how things were, he replied, " Well, so far the exercise is going fine, but I can't find any bloody umpires.

"[1] Fox's platoon was then ordered by Major John Howard to assist in defending the area around both bridges by forming fighting patrols and moving to the nearby village of Benouville.

Fox was a member of the advance party of 2nd Ox and Bucks which was sent to India in August 1945 to prepare for an airborne assault in the Far East.

He was Military Assistant to the Governor of Cyprus Sir Hugh Foot, later Lord Caradon.
