When the situation in the Karelian Front was getting too critical went Finnish diplomatic delegation to Moscow to negotiate for the terms of peace. Peace negotiation started on 8 March 1940. Finnish army was supported by Western countries and their sympathies were with Finland.

Soviet Union saw the danger that the on going war could escalate to an international crisis and so rattled tight rules for the peace. Finland had nothing to do but to accept the terms in the critical situation. So took the cease-fire effect on 13 March 1940 at 11.00 hours as told on the peace treatment. Finland had stopped the Red Army at the critical moment on the Gulf of Finland but suffered several area losses for the Soviet Union under the peace treatment or the peace of Moscow after 105 days of fighting.

Finnish Lentorykmentti 2 (Avition Regiment 2) had fought well with their obsolescent and small number of fighters like Fokker D.21s. Lentorykmentti 2 had flown 3486 flights and shot down 170 Soviet planes and damaged 70 other. This raised ten Finnish fighter aces but Finnish Air Force also suffered the loss of 23 fighters. In total, Finnish Air Force flew 5693 flights, downed 207 Soviet planes and lost 53 planes in combat. In addition Finnish AA gunnery shot down 314 Soviet planes.
