The remnants of Manteuffel's strike force were pulled back for one final attempt to take Bastogne.[83] Panzer Lehr began to move into its new positions,[86] after US 4th Armored Division, the spearhead of George Patton's US Third Army, began its attack to relieve Bastogne[87] and a corridor to the surrounded 101st Airborne was created.[88] Panzer Lehr was then involved in the unsuccessful operations to close the corridor,[89] and finally the exhausted division was pulled out of the battle.
