On the assumption that the French were already prosecuting the retreat, the 6th Division had been ordered forward towards Etain by way of Mars la Tour, to bar the enemy also from the northern road to Verdun. When it reached the height of Tronville, whence could be seen how things really stood, the brigades wheeled to the right in the direction of Vionville and Flavigny. The artillery going on in advance, formed a formidable line of batteries, the fire of which prepared the way for a farther advance, and by half-past eleven the 11th Brigade had taken possession of Vionville in spite of heavy losses. From thence, and from the south, in conjunction with the 10th Brigade, an attack was then directed on Flavigny, which had been set on fire by shell-fire. The different detachments were hereabouts very much mixed, but by skilfully taking advantage of every fold of the ground, the individual regimental officers succeeded in getting their men steadily forward, in spite of the heavy fire of the hostile infantry and artillery. Flavigny was taken by assault, and one cannon and a number of prisoners fell into the hands of the brave Brandenburgers. Vionville, Flavigny and the northern end of the forest of St. Arnould constituted the points of support of the Prussian front now facing to the east; but this front was more than four miles long, and the whole infantry and artillery were engaged up to the hilt all in one line. The second line consisted only of the 5th and 6th Cavalry Divisions and half of the 37th Brigade near Tronville. The position of the French was one of great advantage. Their left flank leaned on Metz, their right was protected by formidable batteries on the old Roman road and a strong force of cavalry; and so they could await with confidence a frontal attack on the part of a venturesome enemy. The possibility of continuing the march to Verdun on this day, under the protection of a strong covering rearguard, was, no doubt, out of the question. Supposing the Marshal earnest above everything to effect his retreat, he could do so only by fighting hard for his right of way, and by so freeing himself from the enemy blocking his path.
