The trio, all members of the 16th Battalion of the Canadian Expeditionary Force, died during the Battle of Hill 70 in August 1917. The identities of the Manitoba soldiers were established through a combination of "historical, genealogical, anthropological, archaeological, and DNA analysis," the DND reports. Private Donegan, an Ottawa-born railway clerk, had been in France for just under four months when he was killed at age 20. Two of his brothers, John and Gavin, were also killed in the Great War, falling in Belgium and France respectively. He was 22 when he died on the first day of the Hill 70 battle.
