Found this on the Mons pocket. Actually surprised the Germans had troops that could surrender...
To the north, advancing on the flank of 21 Army Group, Hodges' First Army was encountering more, but still relatively unsubstantial, opposition. When the Normandy front had collapsed in late July, Hitler had realized that he might need to make a stand between the Seine and the German frontier, and he had, accordingly, ordered the construction of field works along the Somme and Marne Rivers. By the time the jumbled remnants of his western armies reached the Somme line in late August, however, they were too exhausted, disorganized, and demoralized to hold the position. First Army soon cracked the defenses, forcing the Germans to withdraw to the West Wall, a system of fortifications along the German border. As fragments of German formations passed across First Army's front, Bradley saw a chance to cut off their retreat, and he ordered Hodges to turn his direction of advance from northeast to north. Near Mons, in a pocket formed by its three corps, First Army bagged 25,000 prisoners, demolishing what little remained of the German Seventh Army. The coup at Mons cleared the way to the West Wall, and a jubilant Hodges told his staff on 6 September that, with ten more days of good weather, the war would be over.
