At the beginning of June 1940, Primary School No. 1 was turned into a prison for the second time by a group of SS-men who came to Skarżysko. Arrests were carried out and prisoners from Kielce, Starachowice, Iłża, Opatów, Ostrowiec and Sandomierz began to be brought back. On June 29, those arrested were taken to the "Brzask" forest and shot there. The Murder at Dawn was part of the A-B Action against the Polish intelligentsia carried out throughout the General Government. It is estimated that about 760 people lost their lives in the Brzask forest.
