Made a colonel in October 1940, Krebs returned briefly to Moscow in March 1941 as deputy military attaché to General of Cavalry Ernst August Kostring. Because of Kostring's illness, Krebs was acting attaché until the German invasion of the Soviet Union in June. In January 1942, he became chief of staff of Ninth Army. He held the same post in Army Group Center (under Field Marshal Günther von Kluge) beginning in March 1943 and Army Group B (under Field Marshal Walther Model) in September 1944.
Krebs was promoted to Generalmajor (U.S. equiv. brigadier general) in February 1942, Generalleutnant (U.S. equiv. major general) in April 1943, and General der Infanterie (U.S. equiv. lieutenant general) in August 1944. In February 1945, Adolf Hitler ordered Krebs assigned to Berlin, where he succeeded Colonel General Heinz Guderian as acting German army chief of staff following the latter's dismissal on 27 March. With Hitler's suicide on 30 April 1945, Krebs's final duty was to act as the liaison with the Soviets regarding the surrender of the Berlin garrison. Krebs crossed their lines on 1 May to inform the Soviets of Hitler's death and to attempt to negotiate an armistice. His hopes were quickly dashed by the commander of the Eighth Guards Army, General Vasily Chuikov, who insisted on unconditional surrender. Krebs returned to Hitler's bunker, advised Josef Goebbels and Martin Bormann of the situation, and then committed suicide on 1 or 2 May 1945, although his body was never found.
