The Battle of Arnhem was an airborne operation by the Allies, between the 17th and 26th of September 1944 during the Second World War, to secure a bridgehead over the Rhine, thereby opening the way for a thrust towards the Ruhr and a possible early end to the war. It was only partially successful, with 7,600 casualties. Arnhem itself was to be taken by the British while American troops were assigned bridges to the south of the city. Unfortunately, two divisions of the SSPanzer Corps were refitting in Arnhem when the British landed and penned the British troops in, while the American force captured the bridge at Nijmegen but were unable to secure the bridge at Elst. Despite the arrival of Polish reinforcements on the 21st of September, Montgomery ordered a withdrawal four days later. Research Battle of Arnhem
