The Soviet 7th Army, under command of Kirill Meretskov, was now ordered to launch a two-sided flank movement and a direct frontal attack.

Despite many problems, the troops of the Northwest Front advanced to Vyborg, and on the morning of 10 March, the 28th Rifle Corps seized a bridgehead at Vilajoki, which was over five kilometers wide.

At the same time, units of Cherevichenko's cavalry began advancing on the ice of the Gulf of Finland and concentrated on the island of Piisaari, from where he was preparing to bypass the city of Vyborg.

However, flooded areas, supply problems and constant Finnish counterattacks prevented the Red Army from achieving any more visible progress, and until 12 March, the fighting was so intense that both sides in this area reached a state of complete exhaustion.

The Finnish delegation finally accepted Molotov's peace conditions in Moscow on 12 March, and fighting ended the following day.
