  • The Independent Operational Group Polesie emerged on the 11th of September 1939. General Franciszek Kleeberg received orders from Polish Commander in Chief to defend a specific region. This area stretched between the Muchawiec and Prypeć rivers. The headquarters sat within the town of Pińsk. German forces had already broken through central defenses by that date. The group's mission was to prevent encirclement of Polish troops in the center of Poland. It formed from scattered reserve units and second-line formations. Most soldiers belonged to National Defense units or were still mobilizing. A notable exception included elite Border Protection Corps elements. The Riverine Flotilla of the Polish Navy also joined this new formation.

  • On the 22nd of September, Kleeberg found himself cut off from his superiors. He had initially followed orders to retreat toward the Romanian border after the Soviet invasion began on the 17th of September. Supplies ran critically low during this movement. The general decided instead to aid besieged Warsaw. His forces targeted the town of Dęblin where large stores of supplies existed. They crossed the Bug river near Włodawa before making this decision. After Warsaw capitulated on the 28th of September, Kleeberg planned partisan warfare from forest complexes near Świętokrzyskie Mountains. Units engaged Soviet Red Army forces during the days of the 29th and the 30th of September. These engagements resulted in tactical victories for the Polish side despite heavy pressure.

  • Polish units successfully defeated Soviet Red Army forces during late September. This occurred while the group was running low on ammunition and other critical resources. The confrontation happened as they moved westward after losing contact with high command. General Kleeberg redirected his troops away from the Romanian border to assist Warsaw. The fighting against Soviet forces took place between the 29th and the 30th of September. Despite numerical disadvantages, the Poles managed to score several tactical victories. These battles demonstrated the resilience of a force that had been fragmented by rapid German advances. The engagement proved that even isolated units could inflict significant damage on invading armies.

  • The final engagement began on the 2nd of October at the town of Kock. The SGO faced German XIV Mechanized Corps under overwhelming numerical superiority. Polish forces included the 50th Infantry Division nicknamed Brzoza and the 60th Infantry Division known as Kobryń. An improvised Cavalry Division Zaza also participated in these defenses. Total strength reached 18,000 soldiers across all divisions. Despite immense German advantages, the Polish army scored multiple tactical victories. They fought until supplies ran completely out including essential ammunition. The battle continued through early hours of the 6th of October when fighting finally ended. This represented the last organized regular unit of the Polish Army standing against invaders.

  • General Franciszek Kleeberg surrendered on the 5th of October 1939. He became the last Polish general to capitulate during the defensive war. Many soldiers dispersed instead of surrendering and continued guerrilla warfare. Major Henryk Dobrzański led one such Detached Unit of the Polish Army. His force remained active until spring 1940 and is credited as the first partisan unit. Kleeberg himself is considered among few September 1939 generals not defeated in battle. Other commanders like General Stanisław Maczek shared this undefeated reputation. The group sustained casualties over two weeks but received reinforcements from disintegrating units. Defenders of Sarny Fortified Area joined their ranks before final engagement. The legacy of Polesie Group extended far beyond its brief existence.
