Grossdeutschland was with 48th Panzer Corps on the southern face of the salient during Citadelle. After Hitler called off the offensive, he parted out much of Manstein’s panzer divisions elsewhere. Grossdeutschland spent two or three weeks with Army Group Center, but with the German decision to evacuate the rump of the Orel salient, GD is on it’s way back south to deal with the new Soviet attack.
This is the beginning of the German practice of rushing panzer divisions from one crisis to the next.
Thanks for the clarification.
