major in the AIF. This policy was aimed at giving them a broad range of experience, which would benefit the Army, while not allowing them to outnumber the available post-war positions. While commanding the 18th Field Battery, Berryman saw action at the Battle of Passchendaele. For his service as a battery commander in this battle, he received a Mention in Despatches: In September 1918, he was awarded the Distinguished Service Order. His citation, signed by Major General Charles Rosenthal, read: Berryman was later nominated for a bar to his Distinguished Service Order for the September 1918 fighting, but this was subsequently downgraded to a second Mention in Despatches. He was wounded in the right eye in September 1918 while he was commanding the 14th Field Artillery Battery. Although his wound was serious enough to warrant hospitalisation, there was no permanent damage to his vision. It was however the end of his career as a battery commander, as the Army took the opportunity to transfer him to a staff post. From 28 October 1918 to 1 July 1919, he was brigade major of the 7th Infantry Brigade. With the war over, he returned to Australia in October 1919. Between the wars Berryman was appointed to the Staff Corps on 1 October 1920. Although he was entitled to keep his AIF rank of major as an honorary rank, his substantive rank—and pay grade—was still lieutenant. Promotion was painfully slow. He was promoted to captain and brevet major on 1 March 1923, but was not promoted to the substantive rank of major until 1 March 1935. Berryman attended the Royal Military Academy, Woolwich, from 1920 to 1923. On returning to Australia, he became an inspecting ordnance officer at the 2nd Military District. From its headquarters at Victoria Barracks, Sydney, the 2nd Military District administered the Army in most of New South Wales. He enrolled in a Bachelor of Science program at the University of Sydney. On 30 November 1925, he married Muriel Whipp. They eventually had a daughter and a son. Berryman discontinued his university studies to prepare for the entrance examination for Staff College, Camberley. Eighteen Australian Army officers sat the exam that year, but only Berryman and one other officer passed. Only two Australian officers were accepted into staff college each year, so Berryman's attendance from 1926 to 1928 marked him out as one of the Australian Army's rising talents. It
