In 1940 the French went back on their promise and handed captured Luftwaffe crews back to the Germans not to the RAF as agreed !!

I understand the numbers were very high including 400 pilots including 21 BF110 crews ( 12 pilots and 9 gunners )

Winston Churchill commented " they will be used to bomb this country and force our airmen to shoot them down again"......as in many cases they did.

However, were any future aces / Experten in this batch of released crews, that later in the war caused the Allies a problem ?
Also what difference if any would the loss of these crews had made on the Luftwaffe during the soon to arrive Battle of Britain.

Can i just add this is not a snipe at the French, just a genuine question
