On January 30, 1943, Hitler appointed Friedrich Paulus, commander of the Wehrmacht’s 6th Army, as field marshal in Stalingrad… in exchange, Paulus promised never to surrender and to give up his own life rather than be captured.

Twelve hours later, Paulus surrendered to the Red Army, ridiculously breaking his promise and humiliating Hitler, accepting all Soviet demands and asking for mercy in exchange for repentance and collaboration with the USSR.

Hitler’s anger at Paulus’ humiliation was such that he ordered the Gestapo to kidnap his children, Ernst and Olga, and his wife, whom they wanted to force to renounce her married name. They were sent to a Nazi prison in the Alps on Hitler’s direct orders.

After Paulus’ capture, the Soviets put all the Nazi soldiers from his 6th Army to work clearing rubble in the city of Stalingrad, where they destroyed 90% of the buildings… The Soviets then sent the Nazis to break rocks in Siberia. Of the more than 100,000 Nazis captured in Stalingrad, only 6,000 survived, most thanks to the criminal Khrushchev, who released them after Stalin’s death. Paulus was one of them.

Paulus became an informant for the USSR, renounced his ideology, and even joined an anti-Nazi commission organized by the Soviets, from where he asked Hitler to surrender and give up. Paulus also testified at the Nuremberg Trials and accused his own Nazi friends of crimes for which they would receive the death penalty.
