2nd Light Division in the area of Woźniki. After heavy fighting, it withdrew towards Zawiercie, which caused a breach in the defensive line, enabling the Germans both to bypass Polish fortifications in Upper Silesia, and to attack the 7th I.D. from the rear. As a result, the 7th I.D. was destroyed on Sept. 2, and its remaining units retreated to the forests near Koniecpol. This defeat enabled German XVI Panzer Corps to move towards Kielce without any problems. Since Polish Army did not have any reserve units east of Częstochowa, Edward Śmigły-Rydz ordered a detachment of the PZL.23 Karaś bombers to attack the advancing panzers. The attack, however, did not result in a success, and the advance of the Wehrmacht continued. In the south, the Wehrmacht attacked on Sept. 2 in two spots - Mikołów/Pszczyna, and Wysoka/Rabka. Near Pszczyna, Polish 6th I.D. failed to halt the 5th Panzer Division, and in the morning of the same day, the 2nd Panzer Division was stopped in the Battle of Jordanów. At the same time, however, the Germans won the Battle of Węgierska Górka. In the afternoon of September 2, the situation of Kraków Army turned critical. German panzers attacked in large formations in the area of Koziegłowy in the north, and in the area of Jordanów in the south. Furthermore, breach of the Polish lines near Pszczyna caused another problem, as it gave the Germans an opportunity to bypass the Upper Silesian fortifications. As a result, General Szylling, in a conversation with Marshall Śmigły-Rydz stated that it was necessary to withdraw from Upper Silesia and Zaolzie, and to retreat towards Kraków. The Marshall gave tentative permission at 16:00 on Sept. 2, urging Szylling to press his soldiers to do their best. In the evening of September 2, the situation deteriorated further, as Kraków Cavalry Brigade was pushed behind the Warta, and the distance to the retreating remnants of the 7th I.D. was some 30 kilometres. German 2nd Light Division entered this gap, advancing towards Żarki. The Luftwaffe bombed Polish towns and rail junctions, General Szylling was unable to locate the positions of his divisions, and to get in touch with their commandants. At 18:00, Szylling once again talked with Śmigły-Rydz, and 30 minutes later, the Marshall agreed to the withdrawal of Kraków Army to the line marked by the Nida and Dunajec rivers. It was a difficult decision, as it meant that
