In late February 1945, XX Corps crossed the Saar River, penetrated the Siegfried Line, occupied Trier, and seized bridges across the Moselle River.
​Part 1 - Clearing the Saar-Moselle Triangle
The Saar-Moselle Triangle, the region in Germany between the Saar and Moselle Rivers in the extreme southwestern Rhineland-Palatinate, is shown on the accompanying map. A timeline follows. 
  • 14 Jan: XX Corps' 94th Infantry Division begins probing attacks on the Siegfried Switch, aka the Orscholz Switch, a fortified strip reaching from Nennig on the Moselle River to Orscholz at a bend in the Saar River. The Switch forms the base of the Saar-Moselle triangle, the other sides being the Moselle River and its major tributary, the Saar. The 94th Division continues its costly attacks intermittently for a month.
  • 19 Feb: The 94th Infantry Division completes penetration of the western portion of the Switch.
  • 20 & 21 Feb: The 10th Armored Division, supported by additional units, overruns the Saar-Moselle Triangle.
