The division formed a significant part of the ground force used by XV Mountain Corps in Operation Rösselsprung, which was launched on 25 May 1944, with the objectives of killing or capturing the Partisan leader Josip Broz Tito, and destroying his headquarters at Drvar. The division was responsible for two of the nine coordinated thrusts converging on the Partisan stronghold in the Drvar-Bosanski Petrovac area. The first thrust consisted of the 384th (Croatian) Infantry Regiment, referred to as "Kampfgruppe Willam" after its commander. The 384th Regiment group was to advance east at 5 am on 25 May from the village of Srb towards Drvar. "Kampfgruppe Willam" had the primary responsibility for relieving then taking command of 500th SS Parachute Battalion who would land by parachute and glider in Drvar on 25 May, and the regiment was then to attack in the direction of Bosanski Petrovac. The second thrust consisted of a battalion group from the division, which was to set out at 5 am on 25 May from Lapac and drive east through Kulen Vakuf to capture the crossroads at Vrtoče. If necessary, they were then to advance north-west towards Bihać to open the road.
