The 9th Division then penetrated the Siegfried Line near Monschau, then drove to the Rur River between Langerwehe and Düren. During the Battle of the Bulge in December 1944-January 1945, the 9th Infantry Division held the left shoulder of the "Bulge" near Monschau. The division then took part in the drive to capture the Rur River dams, then continued to drive to the Rhine River near Bonn. In March, 1945 Craig commanded all US troops at the Remagen Bridgehead until they resumed the offensive, including the 99th, 78th, and 9th Infantry Divisions. When the 9th Infantry Division resumed its offensive, it continued to the Ruhr Pocket and the Harz Mountains, then made contact with Soviet forces east of the Mulde River at the end of April.
