What day did Poland surrender to the Nazis?
Witold Pilecki
On 17 September, the Soviet Union invaded eastern Poland following the Molotov–Ribbentrop Pact. The Polish government formally surrendered to Nazi Germany on 27 September 1939, but Pilecki and many of his men continued fighting as partisans. His division was disbanded on 17 October, with parts of it surrendering to the enemy. Pilecki went into hiding in Warsaw with his commander Major Włodarkiewicz. On 9 November 1939, the two men founded the Secret Polish Army ("Tajna Armia Polska", TAP), one of the first underground organizations in Poland. Pilecki became organizational commander of TAP as it expanded to cover Warsaw, Siedlce, Radom, Lublin, and other major cities of central Poland.
