By April 1945, victories by Allied and Russian forces had reduced the once formidable German state to a shadow of its former self. Due to increased Allied air attacks on Berlin, Hitler had relocated his headquarters from the Reich Chancellery to the Fuhrerbunker, an underground complex that would serve as the command center for the remnants of the Third Reich earlier in the year. 19th April saw the Soviet Army mobilize its troops to encircle Berlin. Hitler had gone above on 20 April 1945, his 56th birthday, to award the Iron Cross to boys from the Hitler Youth.
It was on 22 April 1945 that Hitler, in an afternoon meeting, learned that Soviets were entering the northern suburbs of Berlin meeting no resistance. It enraged Hitler, who denounced the Army, and made him realize the war was lost. Hitler decided to stay in Berlin rather than flee south.
