Battle of Berlin

The Battle of Berlin, designated the Berlin Strategic Offensive Operation by the Soviet Union, was the final major offensive of the European theatre of World War II.

Following the Vistula–Oder Offensive of January–February 1945, the Red Army had temporarily halted on a line 60 km (37 mi) east of Berlin. On 9 March, Germany established its defence plan for the city with Operation Clausewitz. The first defensive preparations at the outskirts of Berlin were made on 20 March, under the newly appointed commander of Army Group Vistula, General Gotthard Heinrici.

When the Soviet offensive resumed on 16 April, two Soviet fronts (army groups) attacked Berlin from the east and south, while a third overran German forces positioned north of Berlin. Before the main battle in Berlin commenced, the Red Army encircled the city after successful battles of the Seelow Heights and Halbe. On 20 April 1945, Hitler's birthday, the 1st Belorussian Front led by Marshal Georgy Zhukov, advancing from the east and north, started shelling Berlin's city centre, while Marshal Ivan Konev's 1st Ukrainian Front broke through Army Group Centre and advanced towards the southern suburbs of Berlin. On 23 April General Helmuth Weidling assumed command of the forces within Berlin. The garrison consisted of several depleted and disorganized Wehrmacht and Waffen-SS divisions, along with poorly trained Volkssturm and Hitler Youth members. During the next week, the Red Army advanced towards the city centre overcoming tenacious and desperate German house to house resistance.

Before the battle was over, Hitler and a number of his followers committed suicide. The city's garrison finally surrendered on 2 May; however, fighting continued to the north-west, west, and south-west of the city until the end of the war in Europe on 8 May (9 May in the Soviet Union) as German units fought westward so that they could surrender to the Western Allies rather than to the Soviets.

Background
Starting on 12 January 1945, the Red Army began the Vistula–Oder Offensive across the Narew River; and, from Warsaw, a three-day operation on a broad front, which incorporated four army Fronts. On the fourth day, the Red Army broke out and started moving west, up to 30 to 40 km (19 to 25 mi) per day, taking East Prussia, Danzig, and Poznań, drawing up on a line 60 km (37 mi) east of Berlin along the Oder River.

The newly created Army Group Vistula, under the command of Reichsführer-SS Heinrich Himmler, attempted a counter-attack, but this had failed by 24 February. The Red Army then drove on to Pomerania, clearing the right bank of the Oder River, thereby reaching into Silesia.

In the south the Siege of Budapest raged. Three German attempts to relieve the encircled Hungarian capital city failed, and Budapest fell to the Soviets on 13 February. Adolf Hitler insisted on a counter-attack to recapture the Drau-Danube triangle. The goal was to secure the oil region of Nagykanizsa and regain the Danube River for future operations, but the depleted German forces had been given an impossible task. By 16 March, the German Lake Balaton Offensive had failed, and a counter-attack by the Red Army took back in 24 hours everything the Germans had taken ten days to gain. On 30 March, the Soviets entered Austria; and in the Vienna Offensive they captured Vienna on 13 April.

Between June and September 1944, the Wehrmacht had lost more than a million men, and it lacked the fuel and armaments needed to operate effectively. On 12 April 1945, Hitler, who had earlier decided to remain in the city against the wishes of his advisers, heard the news that the American President Franklin D. Roosevelt had died. This briefly raised false hopes in the Führerbunker that there might yet be a falling out among the Allies and that Berlin would be saved at the last moment, as had happened once before when Berlin was threatened (see the Miracle of the House of Brandenburg).
