Black men who tried to enlist were routinely turned away by white recruiting officers. After the Black leaders managed to make a national issue of this rejection, the military finally decided to create an all Black unit in April 1916. The unit that resulted was the No. 2 Construction Battalion, the only segregated Black Battalion in the history of the Canadian Military. This camp was segregated for Blacks only for the No. 2 Construction Battalion in Jura, France.
You could add that men from Saint John were turned away at Camp Sussex. It would be nice to see the connection of the No. 2 Construction Battalion to Saint John.
