The decision adopted by the Great Head-quarters at Buzancy were, as usual, anticipated, and the Commander-in-Chief of the Meuse Army, before the formal orders reached him, had directed the Guard and the 12th Corps to cross the river, by the bridge at Pouilly, constructed on the 30th, and a new one made at Létanne soon after daybreak on the 31st. The Saxon cavalry commander, indeed, taking with him a squadron at dawn, rode down the right bank, then shrouded in fog, as far as Mouzon, entered the town with four lancers, and crossed the bridge to the faubourg. Thereupon a Prussian battalion instantly passed over and took possession of the town. This adventurous squadron had actually captured prisoners and many wagons loaded with provisions. When the two divisions of cavalry, preceding the infantry advance, rode towards Douzy and Carignan, they struck the tail of Lebrun’s Corps, and fired into the distant columns which Ducrot, on the other side of the Chiers, was leading by the hill roads to Francheval. In fact, by noon the Guard horsemen were masters of Carignan and such provision stores as the French had not time to destroy; and the Saxons, passing through Douzy, had fallen upon a convoy on the right bank. The fire of infantry forced them back upon the town, but they held that and the unbroken bridge until the advance guard of the 12th came up in the afternoon and established themselves in the place. The Prussian Guard meanwhile, after a long march, had reached, with its leading battalions, Porru aux Bois and Francheval, the main body halting between Sachy and Missincourt, and the cavalry remaining in the rear. Thus, the Saxon Prince’s Army had secured all the bridges over the Chiers and the important passage at Mouzon, where the 4th Corps stood on both banks of the Meuse. The outposts formed a chain from the right bank of the river in front of Douzy, through Francheval to the Belgian frontier, at that point only nine miles from the Chiers, and sixteen from the Meuse. This narrow belt of territory was thus barred against French enterprise; the road to Montmédy and Metz was definitely closed. The Saxon Prince did not push farther westward, because he knew that the Great Staff had planned a passage of the Meuse below Sedan for the next day, and, therefore, he did not wish to alarm the French. Enough had been done and his troops needed rest, especially the Guard, the whole of which had marched during the day upwards of thirty miles, and the advance guards more. No wonder the French were astounded at the “prodigious marches” made by Germans, whom they had considered to be incapable of such energy and endurance. Some share of the French disasters must be attributed to that fatal form of error—contempt for the enemy.
