Where did Pattons advance start from when targeting bastogne?

Patton's advance towards Bastogne during the Battle of the Bulge began from the area around the town of Luxembourg City. After the German offensive had encircled the town, Patton's Third Army launched a counteroffensive on December 26, 1944, intending to relieve Bastogne. The rapid maneuvering of his forces was crucial in breaking the siege and supporting the besieged American troops.
