For the next three years, the Finns did little to contribute to the battle for Leningrad, maintaining their lines. Their headquarters rejected German pleas for aerial attacks against Leningrad and did not advance farther south from the Svir River in occupied East Karelia (160 kilometres northeast of Leningrad), which they had reached on 7 September. In the southeast, the Germans captured Tikhvin on 8 November, but failed to complete their encirclement of Leningrad by advancing further north to join with the Finns at the Svir River. On 9 December, a counter-attack of the Volkhov Front forced the Wehrmacht to retreat from their Tikhvin positions in the River Volkhov line.
