I learned from my father Wladyslaw Nowik that my grandfather fought in Falaise. Later I found much information including movies on YouTube about World War II and a polish general called general Maczek. Iguess my grandfather Jozef Nowik fought under his command because he was later also stationed in West-Germany.
“1 Dywizja Pancerna gen. Maczka w bitwie pod Falaise” (a movie in polish about the battle in Falaise on YouTube):
