The Battle of the Dnieper was a military campaign that took place in 1943 on the Eastern Front of World War II. One of the largest operations of the war, it involved almost 4,000,000 troops at a time stretched on a 1,400 kilometres (870 mi) front. For four months, the eastern bank of the Dnieper was recovered from German forces by five of the Red Army's fronts, which conducted several assault river crossings to establish several lodgements on the western bank. Kiev was later liberated in the Battle of Kiev.
