On September 12, 1944, the greatest battle in Radomsko's history was fought, the Battle of Evin. The platoon of the General Bema's III Brigade AL stood for battle against a ten-fold larger German army. Nazi forces had 200 standard vehicles (about 6,000 people) as well as armoured vehicles. The enemy repeatedly hit all sides of the grouped People's Army. Thanks to the heroic resistance the enemy plan failed. The losses of the enemy were estimated at approximately 100 killed and 200 wounded. Several vehicles of the enemy were eliminated by the AL's mines, of which one of the cars was filled with a group of German officers who were all killed. When all units of the victorious Poles gathered, it was found that the losses amounted to 12 killed partisans, 11 wounded, and several missing. Later, the actions of Stanisław Sojczyński in the AK also troubled the Germans in the area, as he fought many battles against the Germans during the war. After 1945, he continued to fight, turning his attention to fighting the Red Army.
The significant losses during the war earned the town the nickname of 'Banditenstadt' given by the defeated Germans, meaning 'City of Bandits'. In modern times, the fans of local team RKS Radomsko took pride in the fact the town had such strong resistance to occupying forces and have a flag named "Banditenstadt".
