Charles Costain was married and working as a baker in July 1915 when he enlisted, being allotted to the 9th Battery. The couple had two children and another was on the way. Within months of landing in Egypt he was in trouble with authorities and over the next three years would face disciplinary actions on a number of occasions resulting in lost pay which would have affected his wife and family back home when his pay was stopped. Charles Costain returned home in May 1919. Three more children were born to the couple. In the late 1920’s the family moved to Queenstown where Charles worked as a miner. In May 1942, lowering his age, he enlisted as a signalman in World War 2, serving until June 1945 when he took his discharge. Charles died at Launceston on 14 August 1951.
