Was Dieppe (Aug18) a failure that helped the Allies postpone the Second Front that Russia had been pleading for since 1941? Was it deliberate ? Instead of a Western Front against Germany in France the Allies invaded Italy, not much of a threat to anyone, but an enemy. Germany had to intervene there, so that may have helped Russia. The Second Front didn't come until Normandy in 1944, a year before Germany's surrender and accelerated the murderous bombing of German (and French) cities and their civilians.
No doubts at all about the valour of our Canadian soldiers. I've been thanked in the streets of Dieppe..
