I forgot to post this photo.

I knew the author of this book and this is what he told me.
A comment from Darrell Knight.
The Canadians fighting at Dunkirk - with their British AOP counterparts - appear to have been the last Canadian combatants up to the cease-fire at 1530 British double summer time...no report of another RCAF aerial battle (that I know of) exists, and the Canadian Army called a cease-fire on the ground across Holland and Europe on Saturday, 5 May 1945. Bev was the last to range his guns at Dunkirk , and was interrupted by the cease fire declaration on the HF.
There was an article that came out in the Ottawa Citizen some years ago, about Ray Irwin having fired the last Canadian shot of the war in Europe . Technically this was incorrect, and I sought to correct the error in the book. The B Flight clerks logged the departure and return of each sortie flown (15 operational flights from ALG Wormhout to action-stations over Dunkirk on Monday, May 7, 1945...two days after all fighting had ended in Holland and Germany). In fact, Bev was the last combatant in the air over Dunkirk , when the cease-fire was called (there had also been a British Flight of Auster Vs in the air). I gave the accolade to the whole Flight (and a mention to the British Flight) but in the order they had participated, however, as it was a day-long action involving the Flight's five pilots and six of the observers, including my Dad, #K8712 Gunner Ray Knight.
