Interesting. I currently own two WW2 Canadian Inglis Hi-Powers. They are great guns. The only good thing came out of the Dieppe raid was what NOT to do in future invasions. Looking back at it now, we have to remember that amphibious attacks were in their infancy at that time. Mistakes and sacrifices had to be made, and lessons learned to cut casualties in bigger operations down the road. I will admit that British High Command seemed rather cavalier with the use of “colonials” during dangerous operations.
I also have an Inglis that is one of my favorite Hi-Powers. Wasn’t Dieppe the debut of the Sten gun?
