The time had gone by when they might have taken advantage of their over-hasty mobilization; the inefficient condition of the troops had paralyzed every attempt at activity. France had been long waiting for the news of a victory, and something had to be done to appease public impatience. So, in order to do something, it was resolved (as is usual in such circumstances) to undertake a reconnoissance in force, and, it may be added, with the usual result. On August 2nd three entire Army Corps were set in motion against three battalions, four squadrons, and one battery in Saarbruecken. The Emperor himself and the Prince Imperial shared in the enterprise. The IIIrd Corps advanced on Voelklingen, the Vth through Saargemuend, the IInd on Saarbruecken. Saarbruecken was evacuated after a gallant defence and repeated counter-strokes, but the French did not press across the Saar; convinced, possibly, that they had wasted their strength in a stroke in the air, and had nowhere gained any insight into the dispositions of the enemy. The French military chiefs now hesitated for a long while between conflicting resolutions. Orders were given and recalled on the strength of mere rumours. The left wing was reinforced because 40,000 Prussians were supposed to have marched through Treves, the Guard received contradictory orders, and the bare apparition of a small German force about Loerrach in the Black Forest occasioned the order that the VIIth Corps must remain in Alsace. Thus the French forces were straggled over the wide area between the Nied and the Upper Rhine, while the Germans were advancing in compact masses towards the Saar. This scattered state of their forces finally induced the French leaders to divide them into two separate Armies. Marshal MacMahon took command, but only provisionally, of the Ist, VIIth, and Vth Corps, of which the latter had therefore to draw in to him from Bitsch. The other Corps remained under Marshal Bazaine, with the exception of the Imperial Guard, the command of which the Emperor reserved to himself. It had now become a pressing necessity to protect the left wing of the advancing IInd German Army against the French forces in Alsace, and the IIIrd Army was therefore ordered to cross the frontier on August 4th, without waiting any longer for its trains. The Ist Army, forming the right wing, was in complete readiness near Wadern and Losheim, three or four days' march nearer to the Saar than the IInd Army in the centre. It received the order to concentrate in the neighbourhood of Tholey and there halt for the present. For one thing, this army, the weakest of the three, could not be exposed single-handed to an encounter with the enemy's main force; and for another, it was available to serve as an offensive flank in case the IInd Army should meet the enemy on emerging from the forest zone of the Palatinate.
