Before this could be known, the authorities at headquarters had been convinced that at least the main forces of the enemy were still at Metz; misapprehension, however, prevailed as to the extension of their lines, and it was thought the French front did not reach beyond Montigny. The general in command of the Second Army was therefore instructed not to proceed further northward, but to join the IXth Corps in attacking the enemy's right wing, and move in the direction of Batilly with the Guards and the XIIth Corps. The First Army was not to attack in the front until the Second was ready to strike. In obedience to this, Prince Frederick Charles ordered the IXth Corps to march on to Verneville, and, in case the French right wing should be found there, to open battle by bringing a large force of artillery into action. The Guards were to continue their advance _via_ Doncourt to reinforce the IXth as soon as possible. The XIIth was to remain at Jarny for the present. A little later fresh reports came in which indicated that the IXth Corps, if proceeding in the manner ordered, would come upon the French centre, instead of their right wing. The Prince therefore determined that the Corps should postpone the attack till the Guards had done so at Amanvillers. At the same time the XIIth Corps was pushed on to Ste.-Marie-aux-Chênes. But, while these orders were being given, the first heavy firing was heard at Verneville. This was at twelve o 'clock. The two Corps on the left had, of their own accord, taken an easterly direction without waiting for orders, and the IId Corps moved up behind the IXth at the farm of Caulre. General von Manstein, in command of the IXth, had observed from near Verneville a French encampment at Amanvillers, apparently in a state of quietude. From that point of view the great masses of troops on their immediate left at St.-Privat were not visible. Mistaking this camp for the right wing, he determined to act on his first orders and take the foe by surprise. Eight of his batteries at once opened fire. But it did not take the French troops long to move into the position assigned to them. The independent action of a single Corps naturally exposed it not only to the fire of the troops opposite, but to an attack in flank. To obtain some shelter on the field, the Prussian batteries had taken up a position on the shoulder of the hill below Amanvillers facing the southeast, where they were exposed from the north, on the flank, and even in the rear to the fire of French artillery, as well as to the concentrated fire of their infantry. To meet this, the battalions nearest at hand were ordered forward. 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, forcing their way into the Bois des Genivaux. Thus the line of battle of the 18th Division gained a front of 4,000 paces.
