Łódź Army

Łódź Army was one of the Polish armies that took part in the defensive war of 1939. Formed in the spring of 1939, its primary mission was to cover the central sector of the Polish–German border and defend the vital industrial city of Łódź and the approaches to Warsaw from the west. The army, commanded by General Juliusz Rómmel, was heavily engaged from the first day of the Second World War, fighting major battles as part of the Battle of the Border before its remnants eventually withdrew to participate in the larger Battle of the Bzura.

History

The formation of the Łódź Army was ordered by the Polish General Staff in March 1939 as part of the broader mobilization plan "West" in response to escalating tensions with Nazi Germany. Its creation was a direct response to the German ultimatum to Lithuania and the subsequent occupation of the Klaipėda Region, which signaled Adolf Hitler's aggressive intentions. The army's operational area was strategically critical, situated between the stronger Poznań Army to the north and the Kraków Army to the south, tasked with delaying the advancing Wehrmacht forces. Its establishment reflected the overall Polish defensive strategy, which aimed to defend the entire border rather than concede territory initially, a plan heavily influenced by assurances from France and the United Kingdom.

Organization

At the outbreak of war, the Łódź Army was composed of four infantry divisions and two cavalry brigades, forming a relatively thin screening force. Its core units included the 2nd Legions Infantry Division under Colonel Edward Dojan-Surówka, the 10th Infantry Division, and the 28th Infantry Division. The mobile elements were the Kresowa Cavalry Brigade and the Border Cavalry Brigade. The army also had support from the Sieradz and Łęczyca National Defense units. This force was significantly outmatched by the opposing German 8th Army and 10th Army of Army Group South, commanded by General Gerd von Rundstedt, which possessed superior numbers, armor in the form of Panzer divisions, and overwhelming air support from the Luftwaffe.

Operational history

The Łódź Army's operational history was defined by intense combat from 1 September 1939. It faced the main thrust of the German 10th Army, including the XVI Panzer Corps, aimed directly at Warsaw. Key initial battles included the defense at the Battle of Mokra, where the Wołyńska Cavalry Brigade achieved a temporary success, and the fierce fighting around Piotrków Trybunalski. Despite determined resistance, Polish forces were unable to hold their positions against concentrated Blitzkrieg tactics, leading to a fighting retreat. By 6 September, the army's front was broken, and its disorganized units were ordered to withdraw towards the Vistula River. The remnants of the Łódź Army subsequently merged with the retreating Poznań Army and Pomorze Army to form the largest Polish counter-offensive of the campaign, the Battle of the Bzura.

Commanders

Throughout its brief existence, the Łódź Army had a single commander. General Juliusz Rómmel led the army from its formation until its effective dissolution in early September 1939. A cavalry officer and veteran of the Polish–Soviet War, Rómmel later assumed command of the improvised Warszawa Army during the defense of Warsaw. His chief of staff was Colonel Aleksander Pragłowski. The command structure operated from its headquarters in Łódź, coordinating with the overall Polish commander-in-chief, Marshal Edward Rydz-Śmigły.
