In September of 1939 Poles remained unbroken at the gates of Warsaw. The city was given up after more than two weeks of a siege by the agreement of September 28th. After a week German troops entered the capital of Poland. This place is connected to Stanisław Franciszek Sosabowski. Lieutenant at that time Sosabowski was assigned to command all Polish troops fighting in the area of Grochów (part of Praga). Despite constant bombardment and German attacks repeated every day, Sosabowski managed to hold his objectives at relatively low cost in manpower. On 26 September 1939, the 21st Infantry Regiment led by Sosabowski bloodily repelled the last German attack. Later the war Sosabowski ran away from a German POW camp, commanded in France 1940 and became general. He fought in the Battle of Arnhem leading the Polish 1st Independent Parachute Brigade.
