Po dolinam i po vzgoriam

"Through Valleys and Over Hills" (Russian: По долинам и по взгорьям) or "Through Forests and Over Hills" (Serbo-Croatian: По шумама и горама / Po šumama i gorama), also known as the "Partisan's Song", is a popular Red Army song from the Russian Civil War.

Pyotr Parfyonov wrote the latest version of the song after the 1922 Battle of Volochayevka. It is sung to the melody of "Rozpryahayte, khloptsi, koni", a Ukrainian folk song.

The song has many versions in other languages, including Serbo-Croatian, Greek, German, French, Hungarian, Hebrew, Kurdish, and as well as in many languages of the Soviet Union. The song was adapted by the Yugoslav Partisans and used in World War II.
