When Luther enlisted at Inverell in February 1916, he stated he was born to Mrs Elizabeth Moss of Bugle, Cornwall, England and that his age was twenty five. He was working as an Attendant for Mr. James Campbell of Inverell and was a member of the Rifle Club. Luther joined other district men to form the Second Contingent of The Kurrajongs who departed Inverell together on 29 February 1916.
He became a member of the 33rd Battalion, 2nd Reinforcement which trained at Armidale and Rutherford before sailing from Australia on HMAT A15 Port Sydney in September 1916. They arrived in England on 27 October and were taken to camp at Salisbury Plain. In February 1917 Luther was medically examined and found to be unfit due to ‘chronic eczema’, ‘wasted legs’ and poor development. In May he was attached for duty with the 3rd Australian Auxiliary Hospital in England.
Private Moss returned to Australia in August 1919. Two months later the Inverell Times 28 October 1919 reported that Private Moss had brought home the flag presented to the 33rd Battalion 2nd Reinforcements just before their departure for War. This flag had been made at Inverell by Mrs. Le Brun Brown.
Luther Moss is remembered at Inverell where his name is inscribed on the town’s World War 1 Honor Roll.
