In September 1944, the Allies launched the largest airborne assault of the war, dropping paratroopers into the Netherlands in a bid to seize bridges over the Rhine and end the fighting by Christmas. This film from History Hit tracks the operation's collapse at Arnhem, where British forces landed too far from their objective and ran into German armor that intelligence had missed entirely. It lays out the planning behind the drop zones, the commanders who signed off on the risks, and the radio failures that left units unable to call for support once the fighting started. Archival footage of gliders, paratroopers, and the shattered town of Arnhem sits alongside expert commentary tracing exactly where the plan broke down, from Montgomery's ambitions to the ignored reports of German tanks in the area. The result is less a battle narrative than a case study in how a single bad assumption can unravel an entire campaign.
