Of all Allied airmen, Polish pilots had had the most experience of fighting the Luftwaffe by the time the war came to Britain. As the Battle of Britain raged, they quickly proved themselves as highly aggressive and skilful interceptors, especially when flying the famous Spitfire. The Polish Air Force eventually became the largest non-Commonwealth Spitfire operator, using some 1,500 Mks I, II, V, IX and XVI to devastating effect. Top scoring USAAF ace of the ETO, Francis "Gabby" Gabreski and a whole host of other Allied and Commonwealth aces flew with Polish squadrons, adding even more to their fighting quality. Conversely, several Polish pilots were attached to other Allied squadrons throughout the war, demonstrating their prowess alongside airmen from a whole host of nations. From an expert on Polish fighter aviation, this is a peerless account of the fiery, talented Polish "Spit" pilots, whose country had been overrun and whose aggression and determination to shoot down Axis aircraft was unmatched.
