At the front, German resistance was falling away. Unprecedented numbers of prisoners were taken in the Battle of the Selle, and a new attack was quickly prepared. The French First Army and the British First, Third, and Fourth Armies were tasked with advancing from south of the Condé Canal along a thirty-mile front towards Maubeuge-Mons, threatening Namur. Together with the American forces breaking out of the forests of Argonne, this would, if successful, disrupt the German efforts to reform a shortened defensive line along the Meuse.
