Arnold enlisted in the 3rd Light Horse in August 1914, at the age of 25. He had worked as a shepherd on Williamwood at Ross before signing up. He served at Gallipoli and in the Sinai and Palestine campaign. During the war, Arnold sent several cables home to reassure family about his health and that of his fellow Light Horse men from Ross, Jack Cook and Alan Burbury.
Arnold reached the rank of second lieutenant. His reporting officer described him as a ‘Good leader, good instructor in drill and minor tactics, [and] physically strong’.
After the war he returned to farm work, becoming manager of Williamwood. At both the 1921 and 1925 unveilings at the Ross War Memorial, he commanded the guard of honour. He was also the chairman of the Ross Athletics Club.
He died in 1927 at the age of 38.
Arnold’s story is part of our exhibition: Our Grateful Thanks and Loving Remembrance, a moving and deeply personal exhibition remembering the soldiers whose names are immortalised on the Ross War Memorial.
