Okay, so I am looking at some photographs taken of D-Day, June 6, 1944, when the American, British, and Canadian armies landed in France. Most of the photographs are the usual standard routine seen-them-before photographs, but there are a couple of them, involving the Canadians landing on "Juno" beach, where these guys, instead of coming ashore bearing weapons, are carrying bicycles. Yes, bicycles, hundreds and hundreds of Canadians with bicycles, wading ashore under gun-fire. The text does not explain why. So then.....what were the Canadians doing with bicycles, and did such instruments have any effect on how the invasion went?
