Hello
Kapitan Józef Mańczak (Jozef Manczak) was one of the most important hero of polish aviation in years 1919-1925.
He was born in Poznan in 1896. He finished aviation school in Darmstadt.
During world war I he was served in german's units (also on Richthofen's unit).
After war he fought in polish-soviet war in 1920. He was murdered in April 1940 by soviet's bandits in Katyn. I'm interested in his duty in german's unit durnig World War I.
