The Seven anti-Partisan offensives, known by some sources in the former Yugoslavia as the Seven Enemy offensives (Serbian, Croatian: Sedam neprijateljskih ofanziva/ofenziva), is a group name for seven major Axis military operations on the territory of former Yugoslavia during World War II, undertaken against the Yugoslav Partisans. The First anti-Partisan Offensive (First Enemy Offensive), the attack conducted by the Axis in autumn of 1941 against the "Republic of U?ice", a liberated territory the Partisans established in western Serbia. In November 1941, German troops attacked and reoccupied this territory, with the majority of Partisan forces escaping towards Bosnia. It was during this offensive that tenuous collaboration between the Partisans and the royalist Chetnik movement broke down and turned into open hostility.
