However, the last known "cursed soldier", Józef Franczak, was killed in an ambush as late as 1963, almost 20 years after the Soviet take-over of Poland.
As Stalinist repression intensified over the following years, 50,000 residents of these countries used the heavily forested countryside as a natural refuge and base for armed anti-Soviet resistance.
Resistance units varied in size and composition, ranging from individually operating guerrillas, armed primarily for self-defense, to large and well-organized groups able to engage significant Soviet forces in battle.
An armed resistance movement against the communist government in Romania was active from the late 1940s to the mid-1950s, with isolated individual fighters remaining at large until the early 1960s.
After the overthrow of Nicolae Ceauşescu in 1989, the details about what was called “anti-communist armed resistance” were made public, thanks to the declassification of the Securitate archives.
