In less than five days the assaulting troops sent forward over the plateau had penetrated the French positions to a depth of eight kilometres, and were masters of the most important elements of the defense of the fortress. Verdun and its bridges were only seven kilometres distant. The commander of the fortified region himself proposed to evacuate the whole right bank of the Meuse; the troops established in the Woevre were already falling back toward the bluffs of Cotes de Meuse. Most luckily, on this same day there arrived at Verdun some men of resource, together with substantial reinforcements. General de Castelnau, Chief of the General Staff, ordered the troops on the right bank to hold out at all costs. And on the evening of the 25th General Petain took over the command of the entire sector. The Zouaves, on the left bank, were standing firm as rocks on the Cotes du Poivre, which cuts off access from the valley to Verdun. During this time the Germans, pouring forward from Douaumont, had already reached the Cote de Froideterre, and the French artillerymen, out-flanked, poured their fire into the gray masses as though with rifles. It was at this moment that the 39th division of the famous 20th French Army Corps of Nancy met the enemy in the open, and, after furious hand-to-hand fighting, broke the backbone of the attack. [Sidenote: The German frontal drive checked.] That was the end of it. The German tidal wave could go no farther. There were fierce struggles for several days longer, but all in vain. Starting on the 26th, five French counter-attacks drove back the enemy to a point just north of the fort of Douaumont, and recaptured the village of the same name. For three days the German attacking forces tried unsuccessfully to force these positions; their losses were terrible, and already they had to call in a division of reinforcements. After two days of quiet the contest began again at Douaumont, which was attacked by an entire army corps; the 4th of March found the village again in German hands. The impetus of the great blow had been broken, however, after five days of success, the attack had fallen flat. [Sidenote: German flank attacks.] Were the Germans then to renounce Verdun? After such vast preparations, after such great losses, after having roused such high hopes, this seemed impossible to the leaders of the German army. The frontal drive was to have been followed up by the attack of the wings, and it was now planned to carrying this out with the assistance of the Crown Prince's army, which was still intact. In this way the scheme so judiciously arranged would be accomplished in the appointed manner. Instead of adding the finishing touch to the victory, however, these wings now had the task of winning it completely--and the difference is no small one. [Sidenote: Genius of Petain and Nivelle.]
