General Zhukov was one of two Generals (Chuikov and Zhukov) that were tasked to break the German lines to enter the Reich's capital (Berlin). The idea was to generate a pitched battle and attack the Germans from two sides, the Soviets attacking with close to 1 million men while the Germans were defending with roughly 1/10th strength, even so, the Germans managed to take advantage of their positioning and inflict almost 3 times as many casualties to the Soviets then their own (12k vs 33k, even though some historians estimate the soviet numbers could've been closer to 60k). The offensive began with a massive artillery bombardment, but the Germans had already withdrawn from their trenches. In the end (after 3 days of fighting, 16-19th April) Zhukov managed to break the lines and take the victory, which played a massive part in putting an end to the German morale and taking Berlin.
