 After the war, Berryman took charge of Eastern Command, an appointment he held from March 1946 until his retirement at age 60 in April 1954. Berryman became known for his involvement in charitable organisations such as the War Widows Association, and as head of the Remembrance Drive Project. For this and his commitment to beautifying the Army barracks, Berryman became colloquially known in the Army as "Frank the Florist".
