An armistice was signed in Moscow September 19 between the Soviet Union and Finland.
Finland had to make many limiting concessions: The Soviet Union regained the borders of
1940, with the addition of the Petsamo area. The Porkkala Peninsula was leased to the USSR
as a naval base in Porkkala for fifty years (but returned in 1956), and transit rights
were granted. Finland's army was to demobilize in haste. And Finland was required to expel
all German troops from its territory. As the Germans refused to leave Finland voluntarily,
the Finns had no choice but to fight their former supporters out of Finland in the Lapland
War
.
