At sundown of August 20, 1914, Von Buelow was in position before Namur, three miles from its defenses. Darkness fell upon a hot and sultry August atmosphere. Presently the flashes and boom of the German guns began a bombardment of the trenches between forts Cognelee and Marchovelette. It continued through the night. But the Belgian fortress guns were outranged. It would have been a mere waste of ammunition to reply. Neither could the Belgian infantry venture on a counterattack, for the Germans were clearly observed in overwhelming strength. At the outset the Germans devoted their efforts to clearing the trenches of the Belgian infantry, leaving the forts for subsequent demolition. The unfortunate Belgian infantry, therefore, could do nothing but fire intermittent rifle volleys, without any effect upon the Germans. They bravely bore this storm of shells for ten hours. Not a man who lifted his head above the German machine gun-swept parapets but was not instantly killed or wounded. Thus the majority of the officers were killed, and the ranks within the trenches decimated. Toward morning on August 21, 1914, the Belgians could stand the tornado of death no longer. The demoralized troops fled from the trenches, leaving the gap between forts Cognelee and Marchovelette open. The Germans then opened fire on the forts. In comparison with the new German siege howitzers, the old-fashioned Belgian guns proved to be weak weapons. The tremendous pounding of the German shells not only smashed the fort cupolas, and crumpled into ruin the interior stone and steel protective armor, but quickly put the Belgian guns out of action. Thus while fort Maizeret received some 1,200 German shells at the speed of twenty to the minute, it was able to reply with only ten shots. Forts Marchovelette and Maizeret were the first to fall. Seventy-five men of the Marchovelette garrison were found dead amid its ruins--nearly its total complement. [Illustration: French Invasion of Alsace-lorraine.]
