'Dünkirchen' was a German and Croat pair of operations ('Dünkirchen I' and 'Dünkirchen II') against the partisan forces of Marshal Josip Broz Tito in the Krasić region of the puppet state of Croatia in German-occupied Yugoslavia (27 June/17 July 1944).

Undertaken between 27 June and 2 July, 'Dünkirchen I' was designed to surround and destroy the partisan 8^th Assault Division and 34^th Division in villages centred on Krasić, 11.25 miles (18 km) to the north of Karlovac in the Zumberak mountain region. The Axis force concentrated for this operation comprised, as its German element, the 1^st Don-Kosaken-Reiterregiment of Generalleutnant Hellmuth von Pannwitz’s 1^st Kosaken-Kavalleriedivision, 1^st Reserve Jägerregiment, and 1 and 2/4^th SS Polizeiregiment 'Kroatien', and, as its Croat element, elements of the 5^th, 13^th and 30^th Ustase Battalions, and 4/2^nd Garrison Brigade.

After surrounding the area, the Axis forces began to tighten the net round the area with advances from Ozalj, Draganić, Jastrebarsko and Samobor. The fighting was heavy at times, and see-sawed for almost six days. The partisans successfully defended most of the liberated area around Krasić, and the Germans called off the operation on 2 July.

The partisans then returned immediately to their attacks on the Axis lines of communication between Karlovac and Zagreb, which made a resumption of the operation necessary as 'Dünkirchen II'. Undertaken on 8/17 July, 'Dünkirchen II' involved elements of the partisan 15^th Division as well as the original 8^th Assault Division and 34^th Division, while the Axis force now comprised two regiments of von Pannwitz’s 1^st Kosaken-Kavalleriedivision and the 1^st Reserve Jägerregiment and, as the Croat component, Ustase Pukovnik Tomislav Rolfss 3^rd Ustase Brigade and Podpukovnik Slavko Miletić's 2^nd Garrison Brigade.

Resuming at the point they had desisted on 2 July, the Germans and Croats once again closed on the Krasić area in the Zumberak. The Cossacks and Ustase burned and looted a number of villages as they advanced and eventually captured Metlika, 9.3 miles (15 km) to the west of Krasić and just over the border in Slovenia. The partisans managed to evade a direct confrontation, and the Axis operation concluded on 16 July.

According to the German reports, the Axis losses in both operations were 44 men killed and 221 wounded, while those of the partisans were claimed as 603 men counted dead, several hundred other men estimated killed and wounded, and 19 captured.
