Philip Arthur Lavoie, Service No. 747698
115th Battalion Canadian Expeditionary Force, Saint John, New Brunswick, Canada fought in the Somme, Passchendaele, Ypres, was wounded 3 times, promoted in the field, gassed in the trenches. I would be interested to find more members of his Battalion. I have purchased his military file from the Canadian Archives.
