Operation Market Garden was an Allied military operation during the Second World War fought in the German-occupied Netherlands from 17 to 25 September 1944. Its objective was to create a salient spanning 62 miles (100 km) into German territory with a bridgehead over the Nederrijn (Lower Rhine River), creating an Allied invasion route into northern Germany. This was to be achieved by two sub-operations: seizing nine bridges with combined American, British and Polish airborne forces ("Market") followed by British land forces swiftly following over the bridges ("Garden").
The airborne operation was undertaken by the First Allied Airborne Army with the land operation by the British Second Army, with XXX Corps moving up the centre supported by VIII and XII Corps on their flanks. The airborne soldiers, consisting of paratroops and glider-borne troops numbering around 35,000–40,000, were dropped at sites where they could capture key bridges and hold the terrain until the land forces arrived. The land forces consisted of ten armoured and motorised brigades with approximately 800 tanks and 50,000 soldiers. The land forces advanced from the south along a single road partly surrounded by flood plain on both sides. The plan anticipated that they would cover the 62 miles (100 km) from their start at the Belgian–Dutch border to the Arnhem bridge across the Lower Rhine in 48 hours. About 100,000 German soldiers were in the vicinity to oppose the allied offensive. It was the largest airborne operation of the war up to that point.
