World War II: American troops seize the Ludendorff Bridge over the Rhine river at Remagen.

The Ludendorff Bridge (sometimes referred to as the Bridge at Remagen) 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.

It finally collapsed on 17 March 1945, 10 days after it was captured; 28 Army engineers were killed in the collapse while a further 63 were injured. Of those who died, 18 were actually missing, but presumably had drowned in the swift current of the Rhine River. While it stood, the bridge and newly established pontoon bridges enabled the U.S. Army to establish a bridgehead of six divisions, about 125,000 troops, with accompanying tanks, artillery pieces, and trucks, across the Rhine. Capturing the bridge shortened the war, and V-E Day came on May 8. After the war, the bridge was not rebuilt; the towers on the west bank were converted into a museum and the towers on the east bank are a performing-arts space.
