Resistance in the Těšín Region

Most of the territory of the Těšín region became part of the Reich Province of Upper Silesia during the war; a smaller part (Frýdek) was in the Protectorate. Both Czech and Polish resistance groups were active in the region. As for the Polish ones, they were mainly the Armija Krajowa, which was almost dispersed in 1944, the resistance movement of the Polish Socialists (Polska Partia Socjalisztycna) and the Polish Peasant Party (Stonnictwo Ludowe), both of which continued to exist during the entire war despite several arrests. Out of the Czech groups, the Silesian National Council and the Jan Žižka Moravian-Silesian partisan unit, eliminated by the Gestapo in 1944, were active at the end of the occupation.

At the end of the war, Soviet intelligence units were active in the Těšín region, and a number of subversive actions were carried out by the A. M. Grinevsky "Nadozhny" unit; intelligence information for the advance of Soviet troops was obtained by the Avantgard unit.
