In strong contrast to the comradeship and mutual helpfulness displayed by the Prussian Generals, and the eagerness of their troops to hurry into the fight, was the strange vacillation of the Divisions in General Frossard's rear; of which three, indeed, were sent forward to his support, but only two came up, and that when the fight was already ended.
It has been vehemently asserted that the battle of Spicheren was fought in an ill-judged locality, and that it interfered with more important plans. It certainly had not been anticipated. But, generally speaking, a tactical victory rarely fails to fit in with a strategic design. Success in battle has always been thankfully accepted, and turned to account. By the battle of Spicheren the IInd French Corps was prevented from withdrawing unharmed; touch of the enemy's main force was obtained, and to the supreme Direction of the armies was afforded a basis for further resolutions.

Marshal MacMahon in his retreat had taken a direction which entirely severed his touch with Marshal Bazaine.
As he was not pursued, he could have used the Lunéville-Metz railway to effect his union with the French main army; for up to the 9th it was still open. But rumour had it that the Prussians had already appeared in Pont à Mousson, and the state of his troops did not permit him thus early to risk another engagement.
His Ist Corps, therefore, marched southwards on Neufchâteau, whence Châlons could be reached by railway. The Vth Corps was being shifted to and fro by contradictory orders from the Emperor's head-quarters. First it was to proceed to Nancy, then to take an opposite direction towards Langres. On arriving at Charmes it was ordered to Toul, but from Chaumont it was finally directed to proceed to Châlons. General Trochu had there located the newly-formed XIIth Corps, and behind this gathering point the VIIth Corps also managed to get away from Alsace and reach Rheims by rail by way of Bar sur Aube and Paris.
Thus by August 22nd a Reserve Army was formed, consisting of four Corps and two Cavalry Divisions, under the command of Marshal MacMahon, who, however, at a distance, as he was, of about 120 miles, was unable to render timely assistance to Marshal Bazaine, who stood directly in the line of the advancing enemy.
