He flew for the 303 Kosciuszko Squadron. Very interesting book written on the named A Question of Honor By Lynne Olson abd Stanley Cloud.

Great book. The "Question of Honor" cut many ways - the pilots who flew for the honor of Poland, the RAF's honor in their treatment of the unit during the war (they didn't want to cut the foreigners loose, so the Poles almost had to go off the reservation to get into their first scraps), and especially the dishonorable way the Poles were treated at war's end.
Many of these guys were flight instructors, the best of the best and enormously skilled. Olson suggests their reputation for being overly aggressive hot dogs likely came more from their uberness compared to the average BoB pilot, as the Poles were confident enough to dive in where the doctrinaire feared to tread.
