Interestingly, both commanders ordered an all-out offensive for 6 September 1914. Fate, however, was not so patient. The battle would break out a day earlier at a little village northwest of Meaux named Villeroy. The Kaiser’s forces had spent the first month in the west, apparently successfully executing the Schlieffen Plan to perfection, but Joffre had spotted the weaknesses of the overly ambitious strategy and prepared a perfect counterstroke. The swinging right flank of the German advance was exposed as it passed Paris. A new French army was created to attack the German First Army to the northeast of Paris. However, a reserve corps of the First Army was lingering behind the lines just where the new French Six Army started to deploy near Villeroy. The shelling started, the battle was joined, and heavy casualties were taken by the advancing French. However, the German First Army was now aware that a hitherto unknown French force had appeared on its flank. In turning to face them they had begun a domino effect through all five German armies about to attack between Paris and Verdun.
