“Among the group of [Private Hilaire] Dennis’ comrades who had departed before him was Private George Henry Allsop, a conscript from Woodstock, Ontario, who had joined in London, Ontario just days before Dennis. It is likely that Private Allsop, serving with the 18th Battalion, was the first Canadian conscript to be killed in action when he fell in battle near Neuville-Vitasse on 10 June 1918 – a full two months before it is generally thought that Canadian conscripts first saw action.”
