Private Frederic Oliver [Oliver] Gray enlisted in the First World War on 23 May 1916, at the age of 20. He joined his older brother, Oberlin, as a stretcher bearer with the 3rd Australian Field Ambulance. The brothers chose to join the medical corps because, as Quakers, they conscientiously weren't able to take up arms. Oliver was a farmer and living in Tasmania when he joined. He embarked from Melbourne on the Euripides, on 11 September 1916. He disembarked in Plymouth on 6 October 1916. Within two months he proceeded to France. On 24 august 1918, Oliver was in France with Oberlin, when Oberlin was hit by a shell. Oliver carried Oberlin out of the field, and remained with him until he was put in an ambulance and taken to the 55th Casualty Clearing Station in Daours. Oberlin died there a few hours later. Oliver survived the war and lived into his 90's.
