Nice thread!
Adolf Galland had a scrap with Robert Stanford Tuck in the Battle of Britain.
They shot down each others wingmen before disengaging.
When Tuck was later shot down and captured they met and found this out over dinner.
Galland is told to have said something like "That makes us even Stevens"
Always admired Galland to his gentelmanly behaviour towards the allied pilots, - wonder how many of them he took to dinner!
Must be able to dig up more of those stories, - if I do I'll add it.
