[7] Similarly, by October 1941, the forces of the VI Corps had formed a defensive line along – and in parts south of – the river Svir between the lakes Ladoga and Onega.

[9] Following a series of Soviet attacks between December 1941 and April 1942,[10] the Svir front stabilized into stationary or trench warfare.

[15] On 9 June 1944, Soviet forces began the Vyborg–Petrozavodsk offensive by assaulting the positions of the Finnish IV Corps on the Karelian Isthmus.

[16] By then end of 10 June, the Soviets had broken the Finnish main defensive positions and pushed the Finns to the secondary VT-line.

[22] Due to the increased importance of the western Karelian Isthmus, effective 22 June the Finnish forces to the west of Vuoksi were divided between two corps.

[26] Starting from 22 June, the Soviet Leningrad Front planned for the 59th Army to enter Finland proper via an amphibious operation over the Vyborg Bay.

The main Soviet assault began on 4 July, and quickly led to the Finns losing most of the bay islands.

As a result, the sector became largely passive to the end of the war, and the attempted Soviet strategic breakthrough had failed.
