In January 1945 a trainload of 250 Jews who had been rejected as workers at a mine in Goleschau in Poland arrived at Brünnlitz. The boxcars were frozen shut when they arrived, and Emilie Schindler waited while an engineer from the factory opened the cars using a soldering iron. Twelve people were dead in the cars, and the remainder were too ill and feeble to work. Emilie took the survivors into the factory and cared for them in a makeshift hospital until the end of the war. Schindler continued to bribe SS officials to prevent the slaughter of his workers as the Red Army approached.
As the Soviet armed forces advanced, the SS closed down the camps in eastern Poland and made efforts to conceal what had happened. The gas chambers were dismantled, the crematoria dynamited, and the mass graves dug up and corpses cremated. From January to April 1945, the SS sent inmates westward on "death marches" to camps in Germany and Austria.
On 1 January 1945, Hitler and his generals launched Operation North Wind. The goal was to break through the lines of the US 7th Army and French 1st Army to support the southern thrust in the Ardennes offensive, the final major German offensive of the war. After limited initial gains by the Germans, the Americans halted the offensive. By 25 January, Operation North Wind had officially ended.
Hitler transferred his headquarters to the Führerbunker ("Leader's bunker") in Berlin on 16 January 1945, where he (along with Bormann, his secretary Else Krüger, and others) remained until the end of April.
On the night of 17 January 1945, the Germans fled the city, and the students reclaimed the ruined seminary. Wojtyła and another seminarian volunteered for the task of clearing away piles of frozen excrement from the toilets. Wojtyła also helped a 14-year-old Jewish refugee girl named Edith Zierer, who had escaped from a Nazi labour camp in Częstochowa.
Truman's nomination was dubbed the "Second Missouri Compromise" and was well received. The Roosevelt–Truman ticket achieved a 432–99 electoral-vote victory in the election, defeating the Republican ticket of Governor Thomas E. Dewey of New York and running mate Governor John Bricker of Ohio. Truman was sworn in as vice president on January 20, 1945.
In 1944, Planck's son Erwin was arrested by the Gestapo following the attempted assassination of Hitler in the 20 July plot. He was tried and sentenced to death by the People's Court in October 1944. Erwin was hanged at Berlin's Plötzensee Prison in January 1945. The death of his son destroyed much of Planck's will to live.
On 25 January 1945, despite Himmler's lack of military experience, Hitler appointed him as commander of the hastily formed Army Group Vistula (Heeresgruppe Weichsel) to halt the Soviet Red Army's Vistula–Oder Offensive into Pomerania. Himmler established his command center at Schneidemühl, using his special train, Sonderzug Steiermark, as his headquarters.
