The monument commemorates the Battle of Gruszka, which took place on September 29-30, 1944.
The battle was fought during operations on the Eastern Front, between German troops and Polish and Soviet partisans.
In the morning of September 29, a group of about 1,500 people and commanded by Major Henryk Połowniak, pseudonym "Zygmunt", a People's Army group, composed of: "Freedom" and several other, smaller forest units were surrounded by 5,000 German soldiers and gendarmes in the area of the village of Gruszka, 20 kilometers north-west of Kielce.
The concentric attack carried out by the enemy led to the capture of Gruszka in the afternoon and the division of the defense of the People's Army into two isolated centers. Despite this success, the Germans failed to dismember the defensive formations of the partisans, who managed to break out of the encirclement in compact units on the night of 29/30 September. The group's losses amounted to about 50 killed and 70 wounded.
