It was most active in the Łódź Voivodeship, but also in the neighboring provinces of northern Upper Silesia, eastern Poznań and western Kielce.
KWP's creator and leader (since June 1946) was Captain Stanisław Sojczyński (nom de guerre "Warszyc").
Under his leadership, the organization promoted self-defense from Red Army units and liquidation of the most zealous servants of the regime, but also KWP was engaged in requisitions of necessary means.
In August 1945 KWP was strengthened by hundreds of members of the disbanded Home Army, who decided to continue fighting for free Poland.
In the night of April 19/20 of that year, KWP's unit under Jan Rogolka (nom de guerre "Grot") temporarily captured the town of Radomsko, releasing 57 persons incarcerated in local prison by the UB.
