My eleventh Englishman is Major Hawker

"Dear Mum! I send you my warmest birthday wishes and hope that this will be your last birthday during the war. My eleventh Englishman is Major Hawker, twenty-six years old and commander of an English squadron. Prisoners have testified that he was the English Boelcke. I had the hardest fight I've ever had with him. Until I finally shot him down. Unfortunately, we lost our leader three days ago and an aircraft from our squadron eight days ago."
