The Battle of Salla was fought between Finnish and Soviet troops near Salla in northern Finland during the Winter War. The Soviets had orders to advance through Salla to Kemijärvi and Sodankylä, and from there to Rovaniemi in just two weeks. From there they were to advance to Tornio and cut Finland in two. The Finnish troops managed to stop the Soviet advance just east of Kemijärvi. During the last days of February 1940 the Finnish troops were replaced with the Swedish, Norwegian and Danish volunteers of the Stridsgruppen SFK.

La batalla de Petsamo se libró entre las tropas finlandesas y las soviéticas en el área de Petsamo, en el extremo norte de Finlandia, en 1939 y 1940. Las tropas finlandesas estaban ampliamente superadas en número y fueron finalmente obligadas a retirarse, aunque lograron contener a los soviéticos más de lo previsto y causarles serias bajas en su avance, gracias al terreno y el clima extremo.
