IN BARRACKS SQUARE in old Helsinki stands an unusual monument to a war. A towering sculpture of a soldier’s winter snowsuit, its polished steel body is pierced with large round holes, as if still standing after a strafing by cannon fire. It is Finland’s national memorial to the winter war of 1939-40. During that conflict, Finnish troops withstood a huge Soviet force for 105 days, inflicting heavy casualties on the invaders before succumbing to the Red Army’s larger numbers. The Soviet Union imposed harsh terms, taking 10% of its neighbour’s territory. Peace proved fragile, and Finland was soon swept up into the second world war, fighting with Nazi Germany against the Soviet Red Army from 1941-44.
