A little later fresh reports came in, which indicated that the IXth Corps, should it proceed in the manner ordered, would not strike the enemy on his flank, but full on his front. The Prince, in the discretion of his high position, therefore determined that the Corps should postpone its attack till the Guard Corps should have been brought to bear upon Amanvillers. At the same time the XIIth Corps was to push on to Ste. Marie aux Chênes.

But while these orders were being expedited, there was heard from Verneville at twelve o'clock the roar of the first cannon shots.

The two Corps of the left wing had, moreover, of their own accord, taken an easterly direction, and the IIIrd Corps moved up in rear of the IXth to the Caulre farm.

General von Manstein, the commander of the IXth Corps, had observed from Verneville a French camp at Amanvillers, which apparently lay in negligent repose. From his standpoint it could not be discerned that to his left about St. Privat great masses of troops were in position. Thinking that in this camp he had the enemy's right wing before him, he determined to act on his original orders and at once take the foe by surprise. Eight of his batteries at once opened fire.

But the French troops showed great alacrity in moving up into their prepared positions. The isolated initiative of the single Corps naturally drew upon it not only the fire of the troops opposite to it, but also that of the hostile Corps to right and left.

In the effort to find a location affording something of shelter, the Prussian batteries had taken position in a fold of the slope looking towards Amanvillers, and facing to the south-east, where, however, they were exposed from the north, on the flank and even in the rear, to the fire of the enemy's artillery, as well as to the massed fire of his infantry.

To meet this, it was necessary to send forward the infantry battalions nearest at hand. They took possession of the eastern point of the Bois de la Cusse on the left, and on the right seized the farmhouses of L'Envie and Chantrenne, and forced their way into the Bois des Genivaux. Thus the front of the 18th Division in action extended along a distance of 4000 paces.

It had to endure very heavy loss from the circumstance that the French with their long-range Chassepôt rifles could afford to keep out of the effective range of the needle-gun; the artillery suffered exceptionally severely. One of the batteries had already lost forty-five gunners when the enemy's sharpshooters swarmed forward on it. Infantry protection was not available at the moment, and two guns were lost. By two o'clock the batteries still remaining in position were almost unserviceable, and no relief arrived till the Hessian Division reached Habonville, and brought up on the left of the distressed batteries, five batteries on either side of the railway, which diverted on themselves to a considerable extent the concentrated fire of the enemy. The batteries of the 18th Division, which had suffered most, could now be withdrawn in succession, but even in the act of retreat they had to drive off the pursuers by grape-shot.

The artillery of the IIIrd Corps and the Guard also came to the aid of the IXth, and those of the damaged guns of the last, which were still at all fit for service, were at once brought up again into the fighting line. Thus there was formed in front of Verneville and as far as St. Ail an artillery front of 130 pieces, whose fire now opposed the enemy's artillery with conspicuous success. Now that the IIIrd Corps was approaching Verneville and the 3rd Guard Brigade had reached Habonville, it was no longer to be apprehended that the French would succeed in piercing this line.

The main body of the Guard Corps reached St. Ail so early as two o'clock. General von Pape (commanding Ist Guard Division) at once recognized that by wheeling to the east he would not only not strike the enemy on that right flank of his which had to be turned, but would expose his own left flank to the hostile force occupying Ste. Marie aux Chênes. This town-like village, in itself extremely strong, and also strongly flanked by the main stronghold of the enemy's right, it was necessary to gain before making any further advance; but, in obedience to superior orders, the General had to await the co-operation of the Saxon Corps.
