city of Vienna, 3) to stop the Soviet Advance. Interestingly, an additional side-objective was the hope that serious pressure on the Southern Soviet Fronts in Hungary would force the Soviet Command to divert some forces from its northern offensives headed to Berlin towards Hungary. Operation Süd was scheduled to start after a path to Budapest had been established. The operation would be considered a success if 1) Operation Konrad III could pin the Soviets between the Vértes mountains and the Danube, 2) the 8th Army could secure its Front in Northern Hungary, 3) if the incoming panzer armies could be refitted during transit to create the advantage of surprise. Four plans for Operation Süd were produced by high-ranking officials from Army Group South, the 6th SS Panzer Army, and the 6th Army: “Lösung A” by Fritz Krämer of the 6th SS Panzer Army; “Lösung B” and “Lösung C2” by Helmuth Von Grolman of Army Group South; and “Lösung C1” by Heinrich Gaedcke of the 6th Army. There was much fighting and bickering as to which plan should be implemented. The commander of Army Group South, Otto Wöhler, chose “Lösung B”. The four plans were sent to Guderian on 22 February for review, and Army Group South informed Army Group F commander Maximilian von Weichs on 23 February that the operation would commence on 5 March, in anticipation that Operation Südwind (G: South Wind) would have finished successfully by 24 February. If Operation Südwind was successful, Operation Süd's start could be deferred by 8–9 days. On 25 February, Hitler ordered Otto Wöhler, Maximilian von Weichs, and Sepp Dietrich to personally present the plans for Operation Süd to him, along with Guderian (OKH) and Alfred Jodl (OKW), at the Reich Chancellery in Berlin, where he ultimately chose “Lösung C2”. Guderian then ordered Otto Wöhler to increase the daily fuel allowance from 400 to 500 cubic meters (400k to 500k liters) of fuel on February 26, and by February 28 the specifics of the operation, now officially named “Operation Frühlingserwachen” (G:Spring Awakening), were completed. As per “Lösung C2”, 3 offensive prongs were planned, with the main attack of the 6th Army and 6th SS Panzer Army “Frühlingserwachen” being directed towards the Danube through Lakes Velence and Balaton; the 2nd Panzer Army’s “Eisbrecher” (G: Icebreaker) attacking eastward from the western end of Lake Balaton; and the LXXXXI Corps’ “Waldteufel” (G: Forest Devil) attacking north
