    Operation MARKET GARDEN was an unsuccessful Allied military operation, fought in the Netherlands and Germany. It was the largest airborne operation up to that time.

    The plan of action consisted of two operations...

    Market: airborne forces of the First Allied Airborne Army to seize bridges under tactical command of I Airborne Corps

    and

    Garden: ground forces of the Second Army to move north spearheaded by XXX Corps.

    London was suffering badly from V-1 and V-2 attacks launched from the Netherlands, and Churchill was desperate that something be done. Allied generals were asked for plans to eliminate the threat and the only thing offered was what Field Marshal Montgomery had originally proposed for the D-Day invasion, which was quickly modified into Operation MARKET GARDEN.

    Montgomery's goal was to force an entry into Germany over the Lower Rhine. He wanted to circumvent the northern end of the Siegfried Line and this required the operation to seize the bridges across the Meuse River and two arms of the Rhine as well as several smaller canals and tributaries. Crossing the Lower Rhine would allow the Allies to encircle Germany's industrial heartland in the Ruhr from the north. It made large-scale use of airborne forces, whose tactical objectives were to secure the bridges and allow a rapid advance by armored units into Northern Germany.

    It was a grandiose plan that ended after nine days in a costly defeat.

    Operation MARKET GARDEN has remained a controversial battle for several reasons. Perhaps it was just a good plan that was poorly executed. Or perhaps it was more a matter of timing. The Germans, under Field Marshal Walther Model, were in the process of withdrawing from much of the area. Had the Allies waited just a few more days before launching the operation, it could well have turned out differently.

    Several bridges between Eindhoven and Nijmegen were captured at the beginning of the operation but the advance of the ground forces of XXX Corps was delayed by the demolition of a bridge over the Wilhelmina Canal, an extremely overstretched supply line at Son.

    Regardless, the failure of Market Garden ended Allied expectations of finishing the war by Christmas 1944.
