The Mainila incident was a Finnish attack on a Soviet village by the Red Army and the Casus Belli for the Soviet-Finnish winter war.

On November 26, 1939, the Red Army artillery bombed the Soviet border town of Mainila (Russian Майнило), killing four soldiers on the Soviet side. They also demanded the immediate withdrawal of Finnish troops from the border. The Soviet Union announced on 28 November the existing non-aggression pact of 1932, broke the diplomatic relations with Finland on 29 November 1939 and declared war on Finland one day later. However, Finnish investigations revealed that the Soviet artillery had fired the seven shells at Mainila itself. Edit source text
