to reconstruct Poland after the war. The best-known NCO schools included Warsaw's Agricola. The assault groups took part in "major sabotage", including armed struggle against the occupiers. The assault groups formed the backbone of the Home Army's special troops. They liberated prisoners from German prisons and transports, blew up railroad bridges, carried out executions ordered by special courts, and fought pitched battles against German forces. The assault groups in Warsaw were organised into several battalions, including the famous "Baszta", "Zośka", "Parasol" and "Wigry", which later took part in the Warsaw Uprising and were among the most notable and successful units on the Polish side. Other units, mainly in the Radom-Kielce area, joined the partisan units operating in the forests of the Świętokrzyskie Mountains.
