A month later, Saucken commanded the 2nd Army in Prussia and provided logistical support to the Evacuation of East Prussia. In April, his army was renamed to Army East Prussia. On 8 May, Saucken received notice that he had been awarded the Knight's Cross with Oak leaves, Swords, and Diamonds, making him the last of 27 officers to receive this award. Though an airplane stood by to evacuate him, he refused to leave his troops when they surrendered to the Red Army on the following day of 9 May 1945.
