Allied victory Uprisings 1942 1943 1944 1945 The Nagykanizsa–Körmend offensive, carried out between 26 March and 15 April 1945, was part of the 3rd Ukrainian Front's Vienna offensive during World War II against Army Group South (including Hungarian and Croatian[citation needed]) forces defending the Kisbajom–Nagykorpád–Nagyatád–Heresznye defensive line north of the Drava river and west of Lake Balaton.

[1] The objective of the operation was to cut the Axis access to the oil wells and fuel processing plants in the Nagykanizsa region west of Lake Balaton for the protection of which the Army Group South force built up three defensive lines behind the natural water obstacle of the Mura river linked to the western shore of the lake.

The primary opponent on this sector of the front was the 2nd Panzer Army which included the LXVIII and XXII Mountain Corps.

The Bulgarian 1st Army breached the first two defensive Axis lines and crossed the Mura river.

On 7 May, they resumed their advance, which soon became a pursuit of a fleeing enemy and the capture of the remnants of the Wehrmacht and Hungarian troops.
