Before us, and covering Metz, lay the French army, posted on the crest of a ridge extending north, and about its centre curving slightly westward toward the German forces. The left of the French position was but a short distance from the Moselle, and this part of the line was separated from the Germans by a ravine, the slopes, fairly well wooded, rising quite sharply; farther north, near the centre, this depression disappeared, merged in the general swell of the ground, and thence on toward the right the ground over which an approach to the French line must be made was essentially a natural open glacis, that could be thoroughly swept by the fire of the defenders.
The line extended some seven or eight miles. To attack this position, formidable everywhere, except perhaps on the right flank, the Germans were bringing up the combined forces of the First and Second armies, troops that within the past fortnight had already successfully met the French in three pitched battles. On the right was the First Army, under command of General Von Steinmetz, the victors, August 6, of Spicheren, near Saar, and, eight days later, of Colombey, to the east of Metz; while the centre and left were composed of the several corps of the Second Army, commanded by Prince Frederick Charles of Prussia, a part of whose troops had just been engaged in the sanguinary battle of Mars-la-Tour, by which Bazaine was cut off from the Verdun road, and forced back toward Metz.
At first the German plan was simply to threaten with their right, while the corps of the Second Army advanced toward the north, to prevent the French, of whose intentions there was much doubt, from escaping toward Chalons; then, as the purposes of the French might be, developed, these corps were to change direction toward the enemy successively, and seek to turn his right flank. But the location of this vital turning-point was very uncertain, and until it was ascertained and carried, late in the afternoon, the action raged with more or less intensity along the entire line.
But as it is not my purpose to describe in detail the battle of Gravelotte, nor any other, I will speak of some of its incidents merely. About noon, after many preliminary skirmishes, the action was begun according to the plan I have already outlined, the Germans advancing their left while holding on strongly with their right, and it was this wing (the First Army) that came under my observation from the place where the King’s headquarters were located.
