Why does this account of the Petard Pinch not include Canada as one of the vital convoy links between Britain and North America, not to mention Canada's role in escorting and defending convoys from the depredations of the U-Boats? Mentioning only the convoys to and from the US does scant justice to Canada's contribution to the Battle of the Atlantic.
