The Rhine River represented Nazi Germany's last natural defensive barrier. Approximately 766 miles long with an average width of 1,300 feet, the U.S. Army Corps of Engineers deemed it "totally unfordable, even at low water." General George C. Marshall wrote that he "dreaded the advance to the Rhine more than any other operation during the war."
By March 1945, of the original 47 Rhine bridges (22 road and 25 railroad), the Germans had systematically destroyed nearly all:
- Hohenzollern Bridge at Cologne — March 6
- Bonn bridge — March 8
- Kronprinz Wilhelm Bridge at Urmitz — March 9
When American scouts spotted the Ludendorff Bridge still standing on March 7, 1945, it was the only intact crossing from Switzerland to the Baltic Sea.
Hitler's Bureaucratic Failure
Hitler's October 1944 orders regarding bridge demolition ironically contributed to Remagen's survival. After an American bomb accidentally triggered the premature destruction of the Mülheim Bridge in Cologne, Hitler mandated that demolition charges could only be set when the enemy was within five miles, and bridges could only be destroyed by written order from the commanding officer.
This bureaucratic delay, combined with a shortage of proper explosives—only 300kg of weak industrial Donarit arrived instead of the requested 600kg of military TNT—meant the demolition charges failed to bring down the bridge.
"The Crime of Remagen. It broke the front along the Rhine."
— General Albert Kesselring
