The Allies dropped 35,000 paratroopers behind enemy lines to seize a bridge too far. A British intelligence officer had photos of SS Panzer tanks parked nearby. His warnings were dismissed.
In September 1944, with Germany reeling after the Normandy breakout, Field Marshal Montgomery proposed an audacious plan: drop three airborne divisions behind German lines in the Netherlands to seize a series of bridges, creating a 60-mile corridor straight into northern Germany. Allied ground forces would race up the corridor, cross the Rhine at Arnhem, and potentially end the war by Christmas.
The plan had a critical flaw that intelligence tried to flag: aerial reconnaissance photos showed SS Panzer divisions refitting near Arnhem — exactly where the British 1st Airborne Division was supposed to land. Major Brian Urquhart, the intelligence officer who raised the alarm, was sent on medical leave for 'nervous exhaustion.' The SS tanks were not incorporated into the planning.
Operation Market Garden began September 17, 1944, with the largest airborne assault in history: 34,876 paratroopers landing across a narrow corridor in the Netherlands. The American 82nd and 101st Airborne Divisions seized most of their objectives, taking the bridges at Eindhoven and Nijmegen in brutal fighting. But at Arnhem, the British 1st Airborne ran directly into the two SS Panzer divisions and was cut to pieces.
The British paratroopers at Arnhem fought for nine days with what they had — light weapons designed for a 48-hour operation. A small force under Lieutenant Colonel John Frost held the north end of the Arnhem bridge for four days against Panzer tanks, buying time that proved insufficient. Radio equipment failed. Reinforcements couldn't get through. German forces methodically reduced the British perimeter, capturing or killing nearly everyone inside it.
Operation Garden — the ground assault by XXX Corps — moved up a single road through Dutch countryside, exactly as German commanders expected. The road was flanked by terrain impassable to tanks, and German forces blew bridges and set ambushes that repeatedly stopped the advance. The column was never fast enough to relieve Arnhem before the paratroopers were overwhelmed.
Of the 10,000 British paratroopers who landed at Arnhem, roughly 2,000 escaped back across the Rhine after nine days. Over 6,000 were captured and nearly 1,500 killed. Operation Market Garden was the largest Allied defeat of the final year of the war, and the war would not end in 1944. The Rhine crossing that might have been decisive in September would not happen until March 1945 — at a cost of six more months of fighting.
