As a Yank,

...
I would be remiss in pointing out that although Operation Jubilee was primarily a Canadian and British affair, there were also a contingent of U.S. Army Rangers who participated. About 50 Rangers, if I remember the number correctly, of the 1st Ranger Battalion were the First US soldiers to see action on the ground against the German's in WWII. The 3 KIA became the First US ground soldiers killed in the ETO.
That being said, I fully understand that overwhelming importance of Canadian and British contributions and actions at Dieppe. No time more so then the day I visited the cemetery at Brookwood where many of the men who fell that day rest eternally.
Dieppe has always been a facsinating subject to me. And despite it popularly being considered
'a ill conceived plan that was doomed to fail', I firmly believe that the lessons learned at Dieppe were vital to the sucess on the Normandy landings.
I was at Dieppe myself a few years back. I remember standing on the beach, or more accurately what was horribly called a 'beach', looking at the terrain, and thinking just how improbable it was for success but how those brave boys went ahead and tried anyway.
I will go home this evening and peruse my photo collection to see if I have anything to add to Owen's great post. Somehow, during my visit there in 2004 I missed the Commonwealth Cemetery. An oversight I hope to make up someday.
