On the German side the victory at St Privat was at once followed up by the headquarters. Early on the 19th the investment of Bazaine’s army in Metz was commenced. A new army, the Army of the Meuse (often called the IV.), was as soon as possible formed of all troops not required for the maintenance of the investment, and marched off under the command of the crown prince of Saxony to discover and destroy the remainder of the French field army, which at this moment was known to be at Châlons.
The operations which led to the capture of MacMahon’s army in Sedan call for little explanation. Given seven corps, each capable of averaging 15 m. a day for a week in succession, opposed to four corps only, shaken by defeat Campaign of Sedan. and unable as a whole to cover more than 5 m. a day, the result could hardly be doubtful. But Moltke’s method of conducting operations left his opponent many openings which could only be closed by excessive demands on the marching power of the men. Trusting only to his cavalry screen to secure information, he was always without any definite fixed point about which to manœuvre, for whilst the reports of the screen and orders based thereon were being transmitted, the enemy was free to move, and generally their movements were dictated by political expediency, not by calculable military motives.
Thus whilst the German army, on a front of nearly 50 m., was marching due west on Paris, MacMahon, under political pressure, was moving parallel to them, but on a northerly route, to attempt the relief of Metz.
So unexpected was this move and so uncertain the information which called attention to it, that Moltke did not venture to change at once the direction of march of the whole army, but he directed the Army of the Meuse northward on Damvillers and ordered Prince Frederick Charles to detach two corps from the forces investing Metz to reinforce it. For the moment, therefore, MacMahon’s move had succeeded, and the opportunity existed for Bazaine to break out. But at the critical moment the hopeless want of real efficiency in MacMahon’s army compelled the latter so to delay his advance that it became evident to the Germans that there was no longer any necessity for the III. army to maintain the direction towards Paris, and that the probable point of contact between the Meuse army and the French lay nearer to the right wing of the III. army than to Prince Frederick Charles’s investing force before Metz.
The detachment from the II. army was therefore countermanded, and the whole III. army changed front to the north, while the Meuse army headed the French off from the east. The latter came into contact with the head of the French columns, during the 29th, about Nouart, and on the 30th at Buzancy (battle of Beaumont); and the French, yielding to the force of numbers combined with superior moral, were driven north-westward upon Sedan (q.v.), right across the front of the III. army, which was now rapidly coming up from the south.
During the 31st the retreat practically became a rout, and the morning of the 1st of September found the French crowded around the little fortress of Sedan, with only one line of retreat to the north-west still open. By 11 A.M. the XI. corps (III. army) had already closed that line, and about noon the Saxons (Army of the Meuse) moving round between the town and the Belgian frontier joined hands with the XI., and the circle of investment was complete. The battle of Sedan was closed about 4.15 P.M. by the hoisting of the white flag. Terms were agreed upon during the night, and the whole French army, with the emperor, passed into captivity.
(F. N. M.)
Thus in five weeks one of the French field armies was imprisoned in Metz, the other destroyed, and the Germans were free to march upon Paris. This seemed easy. There could be no organized opposition to their progress,[4] and Paris, Later operations. if not so defenceless as in 1814, was more populous. Starvation was the best method of attacking an overcrowded fortress, and the Parisians were not thought to be proof against the deprivation of their accustomed luxuries. Even Moltke hoped that by the end of October he would be “shooting hares at Creisau,” and with this confidence the German III. and IV. armies left the vicinity of Sedan on the 4th of September. The march called for no more than good staff arrangements, and the two armies arrived before Paris a fortnight later and gradually encircled the place—the III. army on the south, the IV. on the north side—in the last days of September. Headquarters were established at Versailles. Meanwhile the Third Empire had fallen, giving place on the 4th of September to a republican Government of National Defence, which made its appeal to, and evoked, the spirit of 1792. Henceforward the French nation, which had left the conduct of the war to the regular army and had been little more than an excited spectator, took the burden upon itself.
The regular army, indeed, still contained more than 500,000 men (chiefly recruits and reservists), and 50,000 sailors, marines, douaniers, &c., were also available. But the Garde Mobile, framed by Marshal Niel in 1868, doubled this figure, and the addition of the Garde Nationale, called into existence on the 15th of September, and including all able-bodied men of from 31 to 60 years of age, more than trebled it. The German staff had of course to reckon on the Garde Mobile, and did so beforehand, but they wholly underestimated both its effective members and its willingness, while, possessing themselves a system in which all the military elements of the German nation stood close behind the troops of the active army, they ignored the potentialities of the Garde Nationale.
