Josip Broz Tito (far right) with his ministers and staff

Operation Rösselsprung was a combined airborne and ground assault by the German XV Mountain Corps on the Supreme Headquarters of the Yugoslav Partisans during World War II. Launched on 25 May 1944, the operation was aimed at the Partisan leader Marshal Josip Broz Tito (pictured) and his headquarters. It is associated with the Seventh Enemy Offensive. The operation involved direct action via an airborne assault by the 500th SS Parachute Battalion and a planned subsequent link-up with ground forces, including Home Guard forces of the Independent State of Croatia and collaborationist Chetniks. Tito, his principal staff and Allied military personnel escaped. The operation failed due to fierce Partisan resistance, the failure of the various German intelligence agencies to share the limited intelligence available on Tito's exact location, and the lack of contingency planning by the commander of the German airborne force.
