] The battle can be divided into four phases: • 1 September: successful Polish defense of the outer positions near the
Brzeźce and
Wisła Wielka villages. • 2 September, morning: Polish defense of the main positions near Pszczyna. • 2 September, afternoon: battles near
Ćwiklice. • 3 September - 4 September: Polish successful separation and withdrawal, however they paid dearly (Polish withdrawal was successful mainly thanks to a diversionary counterattack on Ćwiklice made by two battalions from the 16th infantry regiment which gave time for other units to regroup and withdraw). During the second day of the battle Polish forces suffered a defeat and were forced to retreat. The main reason of their defeat (apart from huge German material and numerical superiority) was that the Polish commanders incorrectly predicted the direction of the main German attack on 2 September. As the result, the whole Polish plan of defense failed, because then it became impossible to activate a huge trap, which was prepared for German tanks, called the "big bag" trap, which was weak in front, but strong on its sides - with strong artillery assisting in attacking targets which entered the 'bag'. Also, overmuch certainty after great successes of the previous day (especially fierce, few hours-long combat - with use of the "big bag" trap - near Brzeźce village) contributed to Polish defeat. Because of their certainty, Polish commanders decided to make "the big bag trap" more shallow - which meant that it was less flexible, and Polish positions would be easier to crush if the defense was not successful (as it happened) - but on the other hand - if the defense was successful (which didn't happen since the unexpected direction and strength of the German main attack were deadly), the shallow "bag" would be more effective because the German attack would be stopped faster and with greater casualties for the enemy due to a greater concentration of firepower. The defeat suffered at Pszczyna (which also caused a loss of a significant percent of divisional artillery) forced the Polish High Command to pull back the entire frontline, and cede the territory of
Upper Silesia to the Germans. ;German equipment losses and Polish equipment losses and casualties (list may be incomplete)
