9. The Battle of Tannenberg Line (1944)
Estonia’s forested highlands saw Soviet and German troops endure harsh rain and freezing temperatures. Muddy, then frozen ground hampered movement, testing supply chains and morale as both sides fought for strategic control. The battle culminated in a German victory, with the Soviet forces suffering significant casualties. The Tannenberg Line became a symbol of the intense and grueling nature of warfare in the region.
