Kozara (1962)

The Battle of Kozara, known as the "third offensive", is the hardest and most tragic battle led by the Yugoslav partisans in World War II. In June of 1942 the Germans and their collaborators decide to get rid of partisans and their stronghold in the woods of Mount Kozara in Northern Bosnia. They encircle the mountain and begin a mop up operation. Outgunned and outnumbered, the partisans must not only take care of themselves but try to protect thousands of refugees too.
