The II Corps was a unit of the Finnish Army during the Continuation War. During the war the corps participated in combat first northwest of Lake Ladoga and on the Karelian Isthmus before moving to the Povenets–Lake Segozero region by late 1941. During the Soviet offensive of 1944, the corps conducted a fighting retreat to the region of Ilomantsi, with parts of its forces participating in the subsequent Battle of Ilomantsi.

The Vyborg–Petrozavodsk offensive or Karelian offensive was a strategic operation by the Soviet Leningrad and Karelian Fronts against Finland on the Karelian Isthmus and East Karelia fronts of the Continuation War, on the Eastern Front of World War II. The Soviet forces captured East Karelia and Vyborg/Viipuri. After that, however, the fighting reached a stalemate.
