Ludendorff Bridge

The Ludendorff Bridge was in early March 1945 a critical remaining bridge across the river Rhine in Germany when it was captured during the Battle of Remagen by United States Army forces during the closing weeks of the European part of World War II. Built in World War I to help deliver reinforcements and supplies to the German troops on the Western Front, it connected Remagen on the west bank and the village of Erpel on the eastern side between two hills flanking the river.

Midway through Operation Lumberjack, on 7 March 1945, the troops of the 1st U.S. Army approached Remagen and were surprised to find that the bridge was still standing. Its capture, two weeks before Field Marshal Bernard Montgomery's meticulously planned Operation Plunder, enabled the U.S. Army to establish a bridgehead on the eastern side of the Rhine. After the U.S. forces captured the bridge, German forces tried to destroy it multiple times.
