The Battle of Rautu was a 1918 Finnish Civil War battle, fought in Rautu, Finland (now Sosnovo, Leningrad Oblast, Russia) from 21 February to 5 April 1918 between the Finnish Whites and the Finnish Reds supported by the Russian Bolsheviks. The battle was fought by the Rautu railway station, taken by the Reds in late February and soon sieged by the Whites. After weeks of trench warfare, the Whites launched their decisive attack and finally smashed the Red defense on 5 April. The last two days of the Rautu battle were one of the most fierce of all the Finnish Civil War battles. The battle is known as the massacre in the "Death Valley", where more than 400 fleeing Reds were killed by machine gunfire. Unlike any other Finnish Civil War battle, the number of Russian Bolshevik troops was remarkable. The Russian interest is explained by Rautu's location only 60 kilometers north of Saint Petersburg. The Bolsheviks were concerned that the Finnish Whites and their ally Germany would launch an attack against the city along the Rautu railway. The Whites, in turn, were protecting their front on the western side of the Karelian Isthmus.
