Operation Market Garden (September 17-September 25, 1944) was an Allied military operation in World War II. Its tactical objectives were to secure a series of bridges over the main rivers of the German-occupied Netherlands by large-scale use of airborne forces together with a rapid advance by armoured units along the connecting roads, for the strategic purpose of allowing an Allied crossing of the Rhine river, the last major natural barrier to an advance into Germany.
The operation was initially successful with the capture of the Waal bridge at Nijmegen on 20 September, but was a failure overall as the final Rhine bridge at Arnhem was never taken and a German counter-offensive destroyed the British 1st Airborne Division. The Rhine would remain a barrier to the Allied advance until March 1945. The defeat of Allied forces at Arnhem is considered the last major German victory of the Western Campaign.
