'Föhn' (ii) was a German and Croat operation against the partisan forces of Marshal Josip Broz Tito in the puppet state of Croatia in German-occupied Yugoslavia (20/23 March 1944).

The undertaking’s objective was the opening of the road between Bosanski Novi and Prijedor and the destruction of elements of the 4^th Assault Division in the area west of Banja Luka in western Bosnia.

The German forces involved were two reinforced battalions of Generalleutnant Emil Zellner’s 373^rd Division (kroatische) and the 2^nd Panzergrenadiersturmbataillon of General Dr Lothar Rendulic’s 2^nd Panzerarmee, and the Croat contribution the 1/13^th Jägerregiment of Pukovnik Zvonimir Stimaković's 4^th Jägerbrigade. There is little reference to this operation in war-time and post-war literature, but apparently went according to plan although the partisan main body avoided contact. The Germans admitted the loss of one man killed and claimed 89 partisans killed.
