Passage: The Battle of Tali-Ihantala (June 25 to July 9, 1944) was part of the Finnish-Soviet Continuation War (1941–1944), which occurred during World War II. The battle was fought between Finnish forces—using war materiel provided by Germany—and Soviet forces. To date, it is the largest battle in the history of the Nordic countries.The battle marked a point in the Soviet offensive when the Finnish forces first prevented the Soviets from making any significant gains. Earlier at Siiranmäki and Perkjärvi the Finns had halted advancing Soviet forces. The Finnish forces achieved a defensive victory against overwhelming odds.After the Soviets had failed to create any breakthroughs at Tali-Ihantala, Vyborg Bay, or Vuosalmi, the Soviet Leningrad Front started the previously planned transfer of troops from the Karelian Isthmus to support Operation Bagration, where they were encountering particularly fierce resistance. Though the Leningrad Front failed to advance into Finland as ordered by the Stavka, some historians state that the offensive did eventually force Finland from the war.
