11. Battle of Suomussalmi (1939-1940)
In one of the Winter War’s most iconic battles, Finnish troops on skis raided and cut off Soviet columns deep in snowy forests. Mastery of winter guerrilla tactics gave Finland the edge, resulting in a decisive, morale-boosting victory. The battle is considered the war’s clearest, most important, and most significant Finnish victory in the northern half of Finland.
