The Allied advance from Paris to the Rhine was one of the final Allied phases in World War II of the Western European Campaign. This phase spans from the end of the Operation Overlord (25 August 1944) incorporating the German winter counter offensive through the Ardennes (commonly known as the Battle of the Bulge) up to the Allies preparing to cross the river Rhine in the early months of 1945. This roughly corresponds with the official U.S. European Theater of Operations Rhineland and Ardennes-Alsace campaigns.
