World War II: At the beginning of the Battle of Remagen, Allied forces unexpectedly captured the Ludendorff Bridge, which possibly hastened the war's conclusion.

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Battle of Remagen was an 18-day battle during the Allied invasion of Germany in World War II. It lasted from the 7th to the 25th of March 1945 when American forces unexpectedly captured the Ludendorff Bridge over the Rhine intact. They were able to hold it against German opposition and build additional temporary crossings. The presence of a bridgehead across the Rhine advanced the Western Allies' planned crossing of the Rhine into the German interior by three weeks.

Operation Lumberjack was a military operation with the goal of capturing the west bank of the Rhine River and seizing key German cities, near the end of World War II in Europe. The First United States Army launched the operation in March 1945 to capture strategic cities in Nazi Germany and to give the Allies a foothold along the Rhine.

The Ludendorff Bridge, also known as the Bridge at Remagen, was a bridge across the river Rhine in Germany which was captured by United States Army forces in early March 1945 during the Battle of Remagen, in the closing weeks of World War II, when it was one of the few remaining bridges in the region and therefore a critical strategic point. Built during World War I to help deliver reinforcements and supplies to German troops on the Western Front, it connected Remagen on the west bank and the village of Erpel on the east bank between two hills flanking the river.
