During Operation Lumberjack, on 7 March 1945, troops of the U.S. Army's 9th Armored Division reached the Ludendorff Bridge during the closing weeks of World War II and were very surprised to see that the railroad bridge was still standing. German defenders had failed to demolish it, leaving it the only one of the 22 road and railroad bridges over the Rhine still standing. U.S. forces were able to capture the bridge. The unexpected availability of the first major crossing of the Rhine, Germany's last major natural barrier and line of defense, caused Allied high commander Dwight Eisenhower to alter his plans to end the war and may have shortened the war in Europe.
