Considerable masses of the enemy were still in front of Mouzon, and upon these the batteries of the IVth Corps, as one after another they came into action, directed their fire. Two Bavarian batteries brought under their fire the bridge at Villers, lower down the river, and prevented it from being used. Then the suburb was carried after a fierce encounter, and here too the bridge across the Meuse was taken and held. The enemy, deprived of every way of retreat, received with a hot fire the 8th Division emerging from the valley of the Yoncq, but was gradually driven back towards the river. The French troops in front of the Bois de Givodeau were also in a hopeless plight; they were assailed by the 7th Division and XIIth Corps, and were dispersed after an obstinate struggle. By nightfall the French had ceased their resistance on the hither side of the Meuse. Many lagging stragglers were taken prisoners, others hid themselves in the copses and farmhouses, or tried to escape by swimming the river.
In this battle, as in the preceding ones, the attack suffered far heavier loss than the defence. The Army of the Meuse lost 3500 combatants, the preponderating loss falling on the IVth Corps. The French estimated their loss at 1800; but in the course of the day and on the following morning, 3000 prisoners, mostly unwounded, fell into the hands of the victors, with 51 guns, 33 ammunition and many other waggons, and a military chest containing 150,000 francs. And, what was of supreme importance, by the result of this battle the French army had been driven into an extremely unfavourable position.
While the IVth Corps had been chiefly sustaining the day's battle, the Saxon Cavalry had pushed forward on the right bank of the Meuse, and had reconnoitred towards Mouzon and Carignan. The Guard Corps reached Beaumont, and General von der Tann with the 1st Bavarian Corps was at Raucourt, having marched by way of La Besace with some slight skirmishing on the way. The IInd Bavarian Corps was assembled at Sommauthe, the Vth Corps had reached Stonne, the XIth, La Besace. Thus seven Corps now stood in close concentration between the Meuse and the Bar.
The King rode back to Buzancy after the battle, as all the villages in the vicinity of the battle-field were crowded with the wounded. Here, as previously at Clermont, was felt the great inconvenience of inadequate lodging for hundreds of illustrious guests and their suites, when, for once in a way for military reasons, head-quarters were established in a small village, instead of in a large town. Shelter for those officers whose duty it was to prepare the necessary orders for the morrow was only found late at night, and with considerable difficulty.
These orders instructed that on the 31st two Corps of the Army of the Meuse should cross over to the right bank of the river, to prevent the possibility of further progress of the French to Metz by way of Montmédy. Two Corps of the army besieging Metz were besides already posted in that direction about Etain and Briey. The IIIrd Army was to continue its movement in the northward direction.
As the situation had now developed itself, it already seemed within sight that the Army of Châlons might be compelled to cross over into neutral territory, and the Belgian Government was therefore asked through diplomatic channels to concern itself with its disarmament in that event. The German troops had orders at once to cross the Belgian frontier, should the enemy not lay down his arms there.
While the Vth French Corps was still fighting about Beaumont, and when the rest of the army had crossed the Meuse, General MacMahon had ordered the concentration of his army on Sedan. He did not intend to offer battle there, but it was indispensable to give his troops a short rest, and provide them with food and ammunition. He then meant to continue the retreat by way of Mézières, which General Vinoy was just then approaching with the newly-formed XIIIth Corps. The Ist Corps, which had arrived at Carignan early in the afternoon, detached two of its divisions to Douzy in the evening to check any further advance of the Germans.
Though any pursuit immediately after the battle of Beaumont was prevented by the intervening river, the retreat of the French soon assumed the ominous character of a rout. The troops were utterly worn out by their exertions by day and night, in continuous rain and with but scanty supplies of food. The marching to and fro, to no visible purpose, had undermined their confidence in their leaders, and a series of luckless fights had shaken their self-reliance. Thousands of fugitives, crying for bread, crowded round the waggons as they struggled forward to reach the little fortress which had so unexpectedly become the central rallying point of a great army.
The Emperor Napoleon arrived at Sedan from Carignan late in the evening of the 30th; the VIIth Corps reached Floing during the night, but the XIIth Corps did not arrive at Bazeilles until the following morning. The Vth Corps mustered at the eastern suburb of Sedan in a fearfully shattered state, followed in the afternoon of the 31st by the Ist, which, after many rear-guard actions with the German cavalry, took up a position behind the Givonne valley. To pursue the march to Mézières on that day was not to be thought of. The XIIth Corps had that same evening to show a front at Bazeilles, where the thunder of their cannon already heralded the arrival of the Germans. The destruction of the bridges there and at Donchery was ordered, but the order remained unexecuted, owing to the worn-out condition of the men.
August 31st.—Of the army of the Meuse the Guard and 12th Cavalry Divisions had crossed the Meuse at Pouilly, and by a pontoon bridge at Létanne, and swept the country between the Meuse and the Chiers. Following close upon the rear of the French and harassing them in skirmishes till they reached their new position, they brought in as prisoners numbers of stragglers. The Guard Corps then crossed the Chiers at Carignan and halted at Sachy; the XIIth pushed on to about Douzy on the Meuse,[21] while its advanced guard thrust ahead on the further side (of the Chiers) as far as Francheval. The IVth Corps remained at Mouzon.
