Kozara Offensive
The Kozara Offensive (also known as Operation West-Bosnien) was fought in 1942 on and around the mountain of Kozara in northwestern Bosnia. It was an important battle of the Yugoslav Partisan resistance movement in World War II. It later became an integral part of Yugoslav post-war mythology, which celebrated the courage and martyrdom of outnumbered and outgunned Partisans and civilians. Certain sources mistakenly identify the Kozara Offensive as part of Operation Trio.
