On February 14, 1942, the Supreme Commander Gen. Władysław Sikorski established the Home Army (AK). It was a continuator of the Polish Victory Service (SZP) and the Union for Armed Struggle (ZWZ), formed to fight the German and Soviet occupying forces from 1939.
As part of publicising the events and tragedy of the Jewish population, Maria Kann, acting in the Council for Aid to Jews, as "Żegota", wrote a brochure containing a description of the creation of the Jewish resistance and the uprising in the Warsaw ghetto.
As part of the activities informing about the fate of the Jewish population, the Home Army published in November 1942 a booklet titled: "Liquidation of the Warsaw Ghetto. Reportage". The author of the booklet, which was printed in underground conditions in 2,000 copies, was Antoni Szymanowski, alias Brun.
On the night of 9-10 February 1940, the first 140 thousand Poles that lived in these areas were deported from the Eastern Borderlands occupied by the Soviet Union, mainly families of Polish military personnel, state officials, as well as forest and railway workers.
