View images taken during Operation Market Garden in World War II. In September 1944, after the Allies achieved success at Normandy and the liberation of Paris, British Field Marshal Montgomery conceived an attack in the Netherlands to weaken the German army and open a path to Germany to cripple the Nazi forces and end the war. The operation was called Market Garden. Market referred to the airborne forces (a combined Allied effort), and Garden referred to the ground forces (British). It was the largest airborne and glider operation in history. But German resistance proved too strong, and Operation Market Garden failed.
