In September 1944, the Allies had launched Operation Market Garden, a major offensive from the Dutch-Belgian border across the south of the Netherlands through Eindhoven and Nijmegen toward the Rhine bridge at Arnhem, with the goal of crossing the Rhine and bypassing the Siegfried Line in preparation for the final drive toward Berlin. Allied airborne troops were defeated at the Rhine bridge in Arnhem and the advance stopped south of the Lower Rhine, resulting in a narrow salient that ran from the north of Belgium across the south-east of the Netherlands.
