The 2nd Armored Division landed in Normandy on 9 June 1944 under the command of then Major General Edward H. Brooks, operated in the Cotentin Peninsula and later formed the right flank of the Operation Cobra assault. It blunted the German attack on Avranches, then raced across France with the rest of the Third Army, reaching the Albert Canal in Belgium on 8 September. It crossed the German border near Sittard, 18 September to take up defensive positions near Geilenkirchen. On 3 October, the division launched an attack on the Siegfried Line from Marienberg, broke through, crossed the Wurm River and seized Puffendorf 16 November and Barmen 28 November
