Between the wars he attended the Royal Naval College, Greenwich from 1927 to 1928, and later served on the staff of the Commander-in-Chief Africa Station and of the Plans Division at the Admiralty before being appointed Assistant Secretary of the Committee of Imperial Defence in 1936.[2]
He served in the Second World War as Senior Assistant Secretary in the War Cabinet Office.[2] He was present at virtually every major decision during that period, attending all the major conferences—Washington, Cairo, Tehran, Yalta and Potsdam—and was instrumental in establishing what became known as the Cabinet War Rooms (now known the Churchill War Rooms).[3]
After the war Hollis became Deputy Secretary (Military) to the Cabinet in 1947 and Commandant General Royal Marines in 1949.[2] He was credited with saving the Royal Marines from being disbanded,[4] and retired in July 1952.
