Weidling prepared to take part in the Battle of the Seelow Heights, which was part of the broader Battle of the Oder-Neisse. Weidling's LVI Panzer Corps was in the centre, flanked by the CI Army Corps to his left and the XI SS Panzer Corps to his right. All three corps were part of General Theodor Busse's 9th Army, which was defending the heights above the River Oder. While all three corps were in generally good defensive positions, they were conspicuously short of tanks. Weidling's commander, Heinrici, recognised the shortage earlier in the day, as Hitler had ordered the transfer of three panzer divisions from Army Group Vistula to the command of recently promoted Field Marshal Ferdinand Schörner. In the middle of the Battle of Berlin, the leader of the Hitler Youth, Artur Axmann, visited Weidling's headquarters and told him that the youngsters of the Hitler Youth were ready to fight and were even now manning the roads in the 56th rear. Weidling argued it was futile for these teenage boys to be thrown into the battle. He told Axmann it was, "the sacrifice of children for an already doomed cause". Axmann did not withdraw them from the battle. By 19 April, with Schörner's Army Group Centre collapsing, Weidling's corps was forced to retreat west into Berlin. The German forces retreat from Seelow Heights during the 19th and 20th left no front line remaining. Commander of the Berlin Defence Area On 22 April, Hitler ordered that Weidling be executed by firing squad on receiving a report that he had retreated in the face of advancing Soviet Army forces, which was in defiance of standing orders to the contrary. Weidling had not actually retreated, and the sentence was called off after he appeared at the Führerbunker to clear up the misunderstanding. On 23 April, Hitler appointed Weidling as the commander of the Berlin Defence Area. Weidling replaced Lieutenant General (Generalleutnant) Helmuth Reymann, Colonel (Oberst) Ernst Kaether, and Hitler himself. Reymann had held the position only since March. The forces available to Weidling for the city's defence included roughly 45,000 soldiers in several severely depleted German Army and Waffen-SS divisions. These divisions were supplemented by the police force, boys in the compulsory Hitler Youth, and 40,000 men of the Volkssturm (militia). The commander of the central government district was SS-Brigadeführer Wilhelm Mohnke. Mohnke had been appointed to his position by Hitler and
