At 4.15 in the morning of February 21, 1916, the great battle began, the German guns deluging the sector with shells of every caliber that smashed and tore the French positions and surroundings until the very face of nature was distorted. French trench shelters vanished and in Caures Wood and La Ville Wood men were buried in the dugouts or blown to fragments. Telephone lines having been cut, communication could only be maintained by runners. News of the great destruction wrought by the German guns, far from depressing the French fighting units, had a stimulating effect. The French front lines crumbled away under the deluge of fire, but their occupants still clung tenaciously to the debris that remained. The German guns were everywhere, and it was useless for French aerial observers to indicate any special batteries for bombardment. The Germans had the greater number of guns and the heavier, but the French artillery was better served on the whole, and there was less reckless expenditure of ammunition. As an illustration of the brilliant work of the French artillery, an eyewitness has described the defense of a position southeast of Haumont Wood. Here one battery was divided into flanking guns in three positions--one to the southeast of Haumont Wood, a second to the south, and a third to the north of Samogneux. The two other batteries were to the south of Hill 312; there was also a supporting battery of six 90-mm. guns. In response to the German attack the French replied with a curtain of fire, but, unchecked by the fearful loss of life, they began to swarm in from all sides. "They reached Caures Wood by the crests between Haumont Wood and Caures Wood itself, and advanced like a flood on our positions. The section which attempted to hold them back adjusted its range to their rate of progress and mowed them down wave after wave. Swept by the storm of shells, the Germans continued to advance and some succeeded in making their way around to the rear of the guns. The French by this time had come to the end of their ammunition, but they did not lose their head, and, destroying their pieces, retreated, bringing a wounded sergeant major along with them." A battery of 90's on the Haumont knoll was forced to stop firing. Pierrard, an adjutant whose battery had ceased to exist, was dispatched by the commander to help. "Pierrard collected his companions and attached himself to the battery, which opened fire again with tremendous effect. Those guns were in action under him for forty-eight hours, during which he kept up constant communication with the group commander, the burden of his song being an incessant demand for ammunition for this truly epic duel with the Germans. "Unfortunately it was impossible to get supplies up. The Germans were so near that Pierrard and his men used their rifles against them; then, finding the position untenable, they blew up their guns and retired." It was during this retreat that the gallant Pierrard was killed.
