Greetings ladies and gentlemen.

After nearly a year of wait, I finally received my grand-uncle's war file from Library and Archives Canada.

So from what I can read, he never went to the front... Even though my father told me that he wasn't the same upon his return in his family. (Which suggest he did fight.) But the fact he went AWL for four months suggest he didn't even cross the Atlantic.

Any veteran on this forum can enlighten me ?
