The losses of the attacking Guards were, in fact, enormous. In the course of half an hour five battalions lost all, the others the greater part of their officers, especially those of the higher grades. Thousands of dead and wounded marked the track of the troops, who, in spite of their losses, pressed forward. The ranks, as fast as they were thinned, closed up again, and their compact formation was not broken even under the leadership of young lieutenants and ensigns. As they got nearer to the enemy the needle-gun did good service. The French were driven from all their foremost positions, where, for the most part, they did not await the final struggle. By a quarter-past six the battalions had advanced to within 600 to 800 paces of Amanvillers and St.-Privat. The troops, weary from long combat, halted under the steeper slopes offering some, though small, protection, and in the trenches just abandoned by the enemy. Only four battalions now remained in reserve at Ste.-Marie, behind the German line, which now extended to a length of 4,000 paces. Every charge of the French cavalry and of Cissy's Division had been persistently repelled with the aid of twelve batteries of the Guards which had now put in an appearance; but the German troops, reduced, as they were, by untold losses, had to face two French Corps for thirty minutes longer before reinforcements came to their aid. It was nearly seven o'clock when, to the left of the Guards, two brigades of the Saxon infantry arrived on the field; the other two were still assembling in the forest of Auboue; their artillery, however, had for some time kept up a lively fire on Roncourt. When Bazaine, at three o'clock, received word that the Germans were extending the line to enclose his right wing, he ordered Picard's Division of the Grenadier Guards, posted at Plappeville, to advance to the scene of action. Though the distance was no more than a mile through the wooded valley on the right of the highway, his all-important reinforcement had not yet arrived at seven o'clock, and Marshal Canrobert, who was hardly able, by the most strenuous efforts, to check the advance of the Prussians, decided to rally his troops closer to the fortified town of St.-Privat. The retreat from Roncourt was to be covered by a small rearguard, as the border of the Bois de Jaumont was to be held.
