Four armies were selected for the operation. First was the Sixth Panzer Army, under SS General Sepp Dietrich—newly created on 26 October 1944, it used the most senior and the most experienced "Waffen-SS": the 1st SS Panzer Division "Leibstandarte Adolf Hitler" as well as the 12th SS Panzer Division "Hitlerjugend". The 6th Panzer Army was the northernmost attack force. It was ordered to capture Antwerp.
