This 1944 frontline documentary chronicles the Red Army’s entry into Bulgaria, showing its collaboration with Bulgarian partisans and the expulsion of Nazi occupying forces. Produced as Front-line Special Issue No. 8, it features operators from multiple Soviet documentary units capturing both military advance and civilian reactions. While some sources (e.g. Barnouw) place Roman Grigoryev in a field role, the official credit is for Mariyana Fideleva as director.
