Puyi was terrified to hear that the Mongolian People's Army had joined Operation August Storm, as he believed that the Mongols would torture him to death if they captured him. The next day, Yamada told Puyi that the Soviets had already broken through the defense lines in northern Manchukuo, but the Kwantung Army would "hold the line" in southern Manchukuo and Puyi must leave at once. The staff of the Salt Tax Palace were thrown into panic as Puyi ordered all of his treasures to be boxed up and shipped out; in the meantime Puyi observed from his window that soldiers of the Manchukuo Imperial Army were taking off their uniforms and deserting. To test the reaction of his Japanese masters, Puyi put on his uniform of Commander-in-Chief of the Manchukuo Army and announced "We must support the holy war of our Parental Country with all our strength, and must resist the Soviet armies to the end, to the very end". With that, Yoshioka fled the room, which showed Puyi that the war was lost. At one point, a group of Japanese soldiers arrived at the Salt Tax Palace, and Puyi believed they had come to kill him, but they merely went away after seeing him stand at the top of the staircase. Most of the staff at the Salt Tax Palace had already fled, and Puyi found that his phone calls to the Kwantung Army HQ went unanswered as most of the officers had already left for Korea, his minder Amakasu killed himself by swallowing a cyanide pill, and the people of Changchun booed him when his car, flying imperial standards, took him to the railroad station.
