I suggest you restudy DDAY. American paratroopers captured nearly all of their objectives, some before the landings even started. I'm not minimizing anything the brits or canadians or australians did on DDAY because they sacrificed tremendously, but compared to what the US went through at Omaha Beach, the landings at Sword, Juno, and Gold were cake walks. The Canadians did meet fierce resistance at Juno beach, and they certainly had a rough go of it, but Omaha was the most heavily defended beach on the Contentin Peninsula. We lost about 2400 guys in under a single day there, and the only way the beachhead could be established was through the efforts of the US Rangers. They scaled sheer cliffs under heavy fire to take out gun emplacements above the beach. When they got up, they were totally exposed. What's worse, the guns had been moved, so they had to search for them under continuing fire for hours. So badass...anyway, I'm not minimizing Canada, they were an integral part of the invasion force. I wrote a big research paper on why the atlantic wall failed during DDAY, so this stuff is fresh in my mind.
Also, consider the Pacific War-some of the most brutal battles of WWII.
If you want real Canadian pride, look up Vimy Ridge-the first time the Canucks fought together as a national unit. Amazing story. I'm damn proud of you all when I read about that.
