After a heavy Soviet offensive overran the last emergency airstrip in Stalingrad on 25 January, the Soviets again offered Paulus a chance to surrender. Paulus radioed Hitler once again for permission. Telling Hitler that collapse was "inevitable," Paulus stressed that his men were without ammunition or food, and he was no longer able to command them. He also said that 18,000 men were wounded and were in immediate need of medical attention. Once again, Hitler rejected Paulus' request out of hand, and ordered Paulus to hold Stalingrad to the death. On 30 January Paulus informed Hitler that his men were only hours from collapse. Hitler responded by showering a raft of field promotions by radio on Paulus' officers to build up their spirits and steel their will to hold their ground. Most significantly, he promoted Paulus to field marshal. In deciding to promote him, Hitler noted that there was no known record of a Prussian or German field marshal ever having surrendered. The implication was clear: Paulus was to commit suicide. Hitler implied that if Paulus allowed himself to be taken alive, he would shame Germany's military history.
