During the Finnish Civil War, after the Battle of Helsinki, German troops who cooperated with the Whites in the fight against the Red Guards, conquered Klaukkala on April 19, 1918 from the Reds with the aim of getting the troops from Helsinki to Hämeenlinna. According to the Germans, the conquest of Klaukkala was a strict operation. The Red Guards defended the hill of the village in the "frustration of despair". They had good positions on the hill, but only four machine guns, possibly against the fourteen machine guns of the Whites. German sources recall that Klaukkala was captured by an assault in an hour and a half, which caught a total of 55 red prisoners.
