[1] Initially there were two Delegations formed, one for the Polish areas annexed by Germany, and one for the General Government.
On 9 January 1944 it was turned into a Council of National Unity (Rada Jedności Narodowej), the parliament of underground Poland.
Despite several instances of successful cooperation with the Soviet Union, most of the Polish representatives and commanders were soon arrested by the NKVD and sent to Russian prisons or to the Gulag.
After the Uprising's suppression, most of the Delegation's members left Warsaw with the civilian population and managed to evade the Germans.
They were promised safe conduct beforehand but immediately arrested by the NKVD, and brought to Moscow, where they were brutally tortured for several months and tried in a staged Trial of the Sixteen.
