Poznań which held 66,000 Germans, and continued its 80 km a day advance, leaving the 8th Guards Army to lay siege to the city, which they finally took on 23 February. Capture of Berlin Along with the 1st Ukrainian Front, 1BF then stormed Berlin in the climactic Battle of Berlin. Marshal Georgy Zhukov was appointed commander of the 1BF, in November 1944, for its last two great offensives of World War II. After the capture of Poland and East Prussia (its capture was finished on 25 April with capture of Pillau) from January–March 1945, the Soviets redeployed their forces during the first two weeks of April. Marshal Georgy Zhukov concentrated 1BF, which had been deployed along the Oder river from Frankfurt in the south to the Baltic, into an area in front of the Seelow Heights. The 2nd Belorussian Front moved into the positions being vacated by the 1BF north of the Seelow Heights. While this redeployment was in progress gaps were left in the lines and the remnants of the German II Army which had been bottled up in a pocket near Danzig managed to escape across the Oder. In the early hours of 16 April the Berlin Offensive Operation started with the objectives of capturing Berlin and linking up with Western Allied forces on the Elbe. The operation started with an assault on the Seelow Heights by 1BF and by Marshal Konev's 1st Ukrainian Front (1UF) to the south. Initially the 1BF had great difficulty smashing through the German lines of defence, but after three days they had broken through and were approaching the outskirts of Berlin. By 22 April 1BF had penetrated the northern and eastern suburbs of Berlin. They finished the encirclement of Berlin on 25 April when units of the 1BF and 1UF met at Kietzen west of Berlin. After heavy street by street and house to house fighting, General Weidling, the commander of Berlin's garrison, met with Marshal Chuikov and surrendered Berlin unconditionally at 15:00 hours local time on 2 May. Post-war On 8 May, after a signing ceremony in Berlin, the German armed forces surrendered to the Allies unconditionally and the war in Europe was over.
