The 2nd Division moved to France in March 1916. Berryman became a temporary captain on 1 April 1916, a rank which became substantive on 10 June 1916. In January 1917, he was posted to the 7th Infantry Brigade as a trainee staff captain. During the Second Battle of Bullecourt he served with 2nd Division headquarters. He was appointed to command the 18th Field Artillery Battery, and became a temporary major on 1 September 1917, which became substantive on 10 September 1917. This was as far as he could go, for Duntroon graduates could not be promoted above 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.
