) along a pontoon bridge, August 1941. The corps headquarters was formed from the peace-time III Corps. Consisting of the
2nd,
15th and
18th Divisions, II Corps was part of the Finnish General HQ's reserve during the
Finnish invasion of East Karelia of the Continuation War. Before the invasion, II Corps was responsible for the defense of the important industrial area of Upper-
Vuoksi, which was deemed vulnerable to a
Soviet attack. After the forces of the
Army of Karelia had reached
Lake Ladoga, the corps joined the invasion with the objective of capturing the
Khiytola–
Elisenvaara area under the command of
Taavetti Laatikainen. By taking control of the region, the corps severed the Soviet land connection north of Lake Ladoga. Having achieved its initial objectives, the Corps continued in the direction of the eastern
Karelian Isthmus. This resulted in several Soviet divisions being cut off along the shore of the lake, which in turn enabled the II Corps to reach the river
Vuoksi. By creating a bridgehead over the river in the region of
Baryshevo, the Corps put pressure on the Soviet forces engaged in the area of
Vyborg. Following the capture of
Petrozavodsk later in 1941, the Corps was reconstituted in that area from forces both already in the region and from those moved from the Karelian Isthmus. Consisting of the
4th,
8th and
14th Divisions, as part of the Army of Karelia, the corps was to advance north from Petrozavodsk towards
Kondopoga, and from there towards the isthmus between
Medvezhyegorsk and
Lake Segozero. The advance halted in
Povenets–Lake Segozero region by December 8th, 1941, and the corps would stay in the region until 1944. == 1942–44 trench warfare phase ==
