What day did Poland surrender to the Nazis?
Invasion of Poland
The Polish Air Force was not destroyed on the ground in the first days of the war. Though numerically inferior, it had been redeployed from major air bases to small camouflaged airfields shortly before the war. Only some trainers and auxiliary aircraft were destroyed on the ground. The Polish Air Force, despite being significantly outnumbered and with its fighters outmatched by more advanced German fighters, remained active until the second week of the campaign, inflicting significant damage on the Luftwaffe.[124] The Luftwaffe lost 285 aircraft to all operational causes, with 279 more damaged, and the Poles lost 333 aircraft.[125]
