 After leaving France, Moore's group crossed the Siegfried Line and reached the Rhine before being withdrawn to Verdun, where they stayed for three weeks without supplies.As it turned out, the Germans had built their infantry along the Siegfried Line and had launched the Battle of the Bulge, which forced Moore's division to fight their way back to the line and losing approximately 12,000 men in the process.On one mission during the battle, Moore and a German-speaking Jeep driver entered a German-occupied town that also served as a Wehrmacht area regimental headquarters.
