from the Drava River. Overarching German military structure OKW (Oberkommando der Wehrmacht) was the overarching military command for the German army in WW2, while the OKH (Oberkommando des Heeres) was officially a high command operating under OKW. Adolf Hitler was the Commander-in-chief of OKH, while also being the supreme commander of OKW. Finding itself issuing more and more direct orders, OKW eventually became responsible for Western and Southern commands, while OKH was responsible for Eastern commands. This operational overlap caused by the centralized command led to disagreements, shortages, waste, inefficiencies, and delays, often escalating to the point where Hitler himself would have to give the final ruling on a matter. For Operation Spring Awakening, the area for the new offensive was set on the borderline between OKW (Army Group F) and OKH (Army Group South), and this would cause troubles. Army Group E wanted to assemble its troops north of the Drava River by February 25, but Army Group South was not prepared to start the offensive this early due to the ongoing Operation Southwind; subsequently, the OKW and Hitler grew more impatient. The chosen course of action on 25 February, "Lösung C2", favored the quicker and farther-reaching joint operation of the 2nd Panzer Army and 6th SS Panzer Army, while "Lösung B" opted to first secure the left flank of the main thrust "Frühlingserwachen" (between Lake Velence and the Danube) before moving south toward the 2nd Panzer army. Guderian was in favor of "Lösung C2" because this plan would shorten the time the 6th SS Panzer Division would need to stay in Hungary. The OKW and OKH did not use common terminology for parts of the offensive, as OKH referred to the entire offensive as Frühlingserwachen, while the OKW referred to the operation attacking north of the Drava as "Waldteufel". Army Group South and the OKH could not agree on how to best utilize the 1st Cavalry Corps. OKH wanted to send the Corps south-west to the 2nd Panzer army, a move Army Group South Commander Otto Wöhler saw of little use since the 2nd Panzer army would have a lower chance of success compared to the main attacking thrust of “Frühlingserwachen”. Wöhler wanted to use the 1st Cavalry Corps on the eastern shore of Lake Balaton, as German intelligence reported that "the enemy is still the weakest between Lake Balaton and the Sárviz Channel". To further complicate matters,
