Battle of Berlin


The Battle of Berlin, designated as the Berlin Strategic Offensive Operation by the Soviet Union, and also known as the Fall of Berlin, was one of the last major offensives of the European theatre of World War II.
After the Vistula–Oder Offensive of January–February 1945, the Red Army had temporarily halted on a line 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 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 disorganised Army and Waffen-SS divisions, along with poorly trained Volkssturm and Hitler Youth members. Over the course of the next week, the Red Army gradually took the entire city.
On 30 April, Hitler killed himself. The city's garrison surrendered on 2 May but fighting continued to the north-west, west, and south-west of the city until the end of the war in Europe on 8 May as some German units fought westward so that they could surrender to the Western Allies rather than to the Soviets.

Background

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 per day, taking East Prussia, Danzig, and Poznań, drawing up on a line east of Berlin along the Oder River.
The new Army Group Vistula, conducted Operation Solstice, 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, Soviet and Romanian forces conducted the Siege of Budapest. Three German divisions' attempts to relieve the 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 Operation Spring Awakening 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.
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.
No plans were made by the Western Allies to seize the city. The Supreme Commander [Western] Allied Expeditionary Force, General Eisenhower, lost interest in the race to Berlin and saw no further need to suffer casualties by attacking a city that would be in the Soviet sphere of influence after the war, envisioning excessive friendly fire if both armies attempted to occupy the city at once. The main Western Allied contribution to the battle was the bombing of Berlin during 1945. During 1945 the United States Army Air Forces launched mass day raids on Berlin and for 36 nights in succession, scores of Royal Air Force Mosquitos bombed the German capital, ending on the night of 20/21 April 1945 just before the Soviets entered the city.

Preparations

The Soviet offensive into central Germany, which later became East Germany, had two objectives. Stalin did not believe the Western Allies would hand over territory occupied by them in the post-war Soviet zone, so he began the offensive on a broad front and moved rapidly to meet the Western Allies as far west as possible. But the overriding objective was to capture Berlin. The two goals were complementary because possession of the zone could not be won quickly unless Berlin was taken. Another consideration was that Berlin itself held useful post-war strategic assets, including Adolf Hitler and the German nuclear weapons program. On 6 March, Hitler appointed Lieutenant General Helmuth Reymann commander of the Berlin Defence Area, replacing Lieutenant General Bruno Ritter von Hauenschild.
On 20 March, General Gotthard Heinrici was appointed Commander-in-Chief of Army Group Vistula, replacing Himmler. Heinrici was one of the best defensive tacticians in the German army, and he immediately started to lay defensive plans. Heinrici correctly assessed that the main Soviet thrust would be made over the Oder River and along the main east-west Autobahn. He decided not to try to defend the banks of the Oder with anything more than a light skirmishing screen. Instead, Heinrici arranged for engineers to fortify the Seelow Heights, which overlooked the Oder River at the point where the Autobahn crossed them. This was some west of the Oder and east of Berlin. Heinrici thinned out the line in other areas to increase the manpower available to defend the heights. German engineers turned the Oder's flood plain, already saturated by the spring thaw, into a swamp by releasing the water from a reservoir upstream. Behind the plain on the plateau, the engineers built three belts of defensive emplacements reaching back towards the outskirts of Berlin. These lines consisted of anti-tank ditches, anti-tank gun emplacements, and an extensive network of trenches and bunkers.
On 9 April, after a long resistance, Königsberg in East Prussia fell to the Red Army. This freed up Marshal Rokossovsky's 2nd Belorussian Front to move west to the east bank of the Oder river. Marshal Georgy Zhukov concentrated his 1st Belorussian Front, 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 1st Belorussian Front north of the Seelow Heights. While this redeployment was in progress, gaps were left in the lines; and the remnants of General Dietrich von Saucken's 2nd Army, which had been bottled up in a pocket near Danzig, managed to escape into the Vistula delta. To the south, Marshal Konev shifted the main weight of the 1st Ukrainian Front out of Upper Silesia and north-west to the Neisse River.
The three Soviet fronts had altogether 2.5 million men, 6,250 tanks, 7,500 aircraft, 41,600 artillery pieces and mortars, 3,255 truck-mounted Katyusha rocket launchers, and 95,383 motor vehicles, many manufactured in the US.

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.
On 19 April, the fourth day, the 1st Belorussian Front broke through the final line of the Seelow Heights and nothing but broken German formations lay between them and Berlin. The 1st Ukrainian Front, having captured Forst the day before, fanned out into open country. One powerful thrust by Gordov's 3rd Guards Army and Rybalko's 3rd and Lelyushenko's 4th Guards Tank Armies were heading north-east towards Berlin while other armies headed west towards a section of the United States Army's front line south-west of Berlin on the Elbe. With these advances, the Soviet forces drove a wedge between Army Group Vistula in the north and Army Group Centre in the south. By the end of the day, the German eastern front line north of Frankfurt around Seelow and to the south around Forst had ceased to exist. These breakthroughs allowed the two Soviet Fronts to envelop the German 9th Army in a large pocket west of Frankfurt. Attempts by the 9th Army to break out to the west resulted in the Battle of Halbe. The cost to the Soviet forces had been very high, with over 2,807 tanks lost between 1 and 19 April, including at least 727 at the Seelow Heights.
In the meantime, RAF Mosquitos conducted tactical air raids against German positions inside Berlin on the nights of 15 April, 17 April, 18 April, 19 April, and 20 April.

Encirclement of Berlin

On 20 April 1945, Hitler's 56th birthday, Soviet artillery of the 1st Belorussian Front began shelling Berlin and did not stop until the city surrendered. The weight of ordnance delivered by Soviet artillery during the battle was greater than the total tonnage dropped by Western Allied bombers on the city. While the 1st Belorussian Front advanced towards the east and north-east of the city, the 1st Ukrainian Front pushed through the last formations of the northern wing of Army Group Centre and passed north of Juterbog, well over halfway to the American front line on the river Elbe at Magdeburg. To the north between Stettin and Schwedt, the 2nd Belorussian Front attacked the northern flank of Army Group Vistula, held by Hasso von Manteuffel's 3rd Panzer Army. The next day, Bogdanov's 2nd Guards Tank Army advanced nearly north of Berlin and then attacked south-west of Werneuchen. The Soviet plan was to encircle Berlin first and then envelop the 9th Army.

The command of the German V Corps, trapped with the 9th Army north of Forst, passed from the 4th Panzer Army to the 9th Army. The corps was still holding on to the Berlin-Cottbus highway front line. Field Marshal Ferdinand Schörner's Army Group Centre launched a counter-offensive aimed at breaking through to Berlin from the south and entering in the 1st Ukrainian Front region, engaging the 2nd Polish Army and elements of the Red Army's 52nd Army and 5th Guards Army. When the old southern flank of the 4th Panzer Army had some local successes counter-attacking north against the 1st Ukrainian Front, Hitler unrealistically ordered the 9th Army to hold Cottbus and set up a front facing west. Next, they were to attack the Soviet columns advancing north to form a pincer that would meet the 4th Panzer Army coming from the south and envelop the 1st Ukrainian Front before destroying it. They were to anticipate a southward attack by the 3rd Panzer Army and be ready to be the southern arm of a pincer attack that would envelop 1st Belorussian Front, which would be destroyed by SS-General Felix Steiner's Army Detachment advancing from north of Berlin. Later in the day, when Steiner explained that he did not have the divisions to achieve this, Heinrici made it clear to Hitler's staff that unless the 9th Army retreated immediately, it would be enveloped by the Soviets. He stressed that it was already too late for it to move north-west to Berlin and would have to retreat west. Heinrici went on to say that if Hitler did not allow it to move west, he would ask to be relieved of his command.
On 22 April 1945, at his afternoon situation conference, Hitler fell into a tearful rage when he realised that his plans, prepared the previous day, could not be achieved. He declared that the war was lost, blaming the generals for the defeat and that he would remain in Berlin until the end and then kill himself.
In an attempt to coax Hitler out of his rage, General Alfred Jodl speculated that General Walther Wenck's 12th Army, which was facing the Americans, could move to Berlin because the Americans, already on the Elbe River, were unlikely to move further east. This assumption was based on his viewing of the captured Eclipse documents, which organised the partition of Germany among the Allies. Hitler immediately grasped the idea, and within hours Wenck was ordered to disengage from the Americans and move the 12th Army north-east to support Berlin. It was then realised that if the 9th Army moved west, it could link up with the 12th Army. In the evening Heinrici was given permission to make the link-up.
Elsewhere, the 2nd Belorussian Front had established a bridgehead deep on the west bank of the Oder and was heavily engaged with the 3rd Panzer Army. The 9th Army had lost Cottbus and was being pressed from the east. A Soviet tank spearhead was on the Havel River to the east of Berlin, and another had at one point penetrated the inner defensive ring of Berlin.
The capital was now within range of field artillery. A Soviet war correspondent, in the style of World War II Soviet journalism, gave the following account of an important event which took place on 22 April 1945 at 08:30 local time:
On 23 April 1945, the Soviet 1st Belorussian Front and 1st Ukrainian Front continued to tighten the encirclement, severing the last link between the German 9th Army and the city. Elements of the 1st Ukrainian Front continued to move westward and started to engage the German 12th Army moving towards Berlin. On this same day, Hitler appointed General Helmuth Weidling as the commander of the Berlin Defence Area, replacing Lieutenant General Reymann. Meanwhile, by 24 April 1945 elements of 1st Belorussian Front and 1st Ukrainian Front had completed the encirclement of the city. Within the next day, 25 April 1945, the Soviet investment of Berlin was consolidated, with leading Soviet units probing and penetrating the S-Bahn defensive ring. By the end of the day, it was clear that the German defence of the city could not do anything but temporarily delay the capture of the city by the Soviets, since the decisive stages of the battle had already been fought and lost by the Germans outside the city. By that time, Schörner's offensive, initially successful, had mostly been thwarted, although he did manage to inflict significant casualties on the opposing Polish and Soviet units, slowing down their progress.
