SUMMA: Russian assault on Mannerheim Line (2/1/40)

Summa, Finland

The Battle of Summa was fought between the Soviet Union and Finland, in two phases, first in December 1939 and then in February 1940. It was part of the Winter War and was fought near the village of Summa (now Soldatskoye) along the main road leading from Leningrad to Viipuri. First battle in December: The village of Summa was a gateway to the city of Viipuri. The Finns had built 41 reinforced concrete bunkers in the Summa area, and the defense line was stronger than elsewhere in the Karelianisthmus. However, the Finns had made mistakes in planning and nearby Munasuo swamp, east of Summa, had a kilometer wide gap in the line. At least 20 tanks drove through the line in the first day of battle, but the Soviets did not have proper co-operation between branches of service; tanks, artillery and troops fought their own battles. The Finns stood still in trenches and allowed the Soviet tanks to move behind the defense line on December 19th, as they did not have proper anti-tank weapons. After that the Finns repelled the Soviet main troops. Soviet tanks cut-off behind the line aimlessly attacked Finnish strongpoints, but once these were eliminated the threat was over. The Finns won the battle on 22 December.
