Operational history

Despite several early successes, such as the Battle of Mokra on 1 September, where the Volhynian Cavalry Brigade stopped the German 4th Panzer Division, the army was forced to withdraw towards the

River under increasing German pressure. The German Army Group South under Gerd von Rundstedt struck along the lines dividing the Polish Army Łódź from Army Poznań and Army Kraków. Without any natural defences, and facing a significant enemy force while lacking support, Rómmel's army was easily outmanoeuvred and cut off from the rest of the Polish forces during the remainder of the battle of the Border, with most of its units being outflanked by the German Eighth Army and the German Tenth Army. Łódź was taken by the Germans on 8 September. By the beginning of the second week of fighting, Army Łódź had suffered heavy casualties and failed to carry out its task of defending its part of the Polish borders. General Rómmel advanced with a small contingent of forces through towards Warsaw, where he assumed command of the improvised Warsaw Army tasked with defending the Polish capital (see siege of Warsaw), but he left most of his forces behind. General Wiktor Thommée assumed command of the remaining units. Piotrków Group, or as it became known after its commander, Thommée's Group, was much more successful, managing to avoid encirclement, and after the Battle of Wola Cyrusowa (September 8) his corps' last battle was the defence of the Modlin fortress (capitulated on 29 September).

Organization

Army's commander was general Juliusz Rómmel. His chief of staff was colonel Aleksander Pragłowski. The Army also contained an Operational Group 'Piotrków' under general Wiktor Thommée. The Army also had smaller notable units, such as two armoured trains (no.52 and no.53).
