Input: Question: What role had Otto Skorzeny been previously? Passage:Operation Panzerfaust (Unternehmen Panzerfaust) was a military operation to keep the Kingdom of Hungary at Germany's side in the war, conducted in October 1944 by the German Wehrmacht. When German dictator Adolf Hitler received word that Hungary's Regent, Admiral Miklos Horthy, was secretly negotiating his country's surrender to the advancing Red Army, he sent commando leader Otto Skorzeny of the Waffen-SS and former special forces commander Adrian von Folkersam to Hungary. Hitler feared that Hungary's surrender would expose his southern flank, where the Kingdom of Romania had just joined with the Soviets and cut off a million German troops still fighting the Soviet advance in the Balkan peninsula. The operation was preceded by Operation Margarethe in March 1944, which was the occupation of Hungary by German forces, which Hitler had hoped would secure Hungary's place in the Axis powers.
