This undated photograph shows one of the two Canadian submarines, CC-1 or CC-2, near an American cruiser, likely during the trip from Esquimalt to Halifax.

Acquired at the start of the war to defend the west coast, in mid-1917 the submarines were moved to Halifax in preparation for a voyage to reinforce Allied forces in the Mediterranean. This arduous voyage took almost four months due to mechanical problems, and since both submarines' diesel engines were worn out by the end, they remained in Halifax for the rest of the war.
