Schlacht um die Seelower Höhen
The sector in which most of the fighting in the overall offensive took place was the Seelow Heights, the last major defensive line outside Berlin. The Battle of the Seelow Heights, fought over four days from 16 until 19 April, was one of the last pitched battles of World War II: almost one million Red Army soldiers and more than 20,000 tanks and artillery pieces were deployed to break through the "Gates to Berlin", which were defended by about 100,000 German soldiers and 1,200 tanks and guns. The Soviet forces led by Zhukov broke through the defensive positions, having suffered about 30,000 dead, while 12,000 German personnel were killed.
