Roger Densham was first sent to Broadmeadows for military training and placed in the 13-18 Reinforcements of the 6th Battalion.

He remained there until 7 January, 1918, when he was detached from duty at Headquarters, Chelsea, for duty at Dartford. His record does not record his role, but he was probably a driver, or else, a mecahnic with the Motor Corps.
