In September 1944, the Allies launched a plan to end the war before Christmas by seizing nine bridges across the Netherlands in a single airborne strike. This History Hit documentary follows that plan, Operation Market Garden, from its ambitious start to its collapse at the ninth and final crossing, Arnhem. Historians walk through the fighting at Nijmegen and along the supply corridor troops nicknamed Hell's Highway, using period footage and maps to show how delays on the ground, broken radio communications, and unexpectedly strong German armor turned a fast-moving plan into a siege. The British 1st Airborne Division, dropped too far from its objective and cut off from relief, ends up making a doomed stand at the bridge itself. The film treats the operation as a case study in how a good plan on paper can unravel through small failures compounding, and closes on the cost: an entire division effectively destroyed in what was, at the time, the largest airborne operation of the war.
