On April 23, Göring sent a radiogram to Hitler. Aware that Berlin was surrounded and the situation hopeless, the Reichsmarschall was prepared to step in and lead the Nazi Party. If he did not hear back by 10:00 p.m. that evening, he would assume the Führer was incapacitated and take command. Hitler did not respond until April 25, 1945, but his reaction was furious and determined: He ordered the SS to arrest his second in command.
