Fortunately for the Prussians, Moltke at Mainz took a different view. Receiving absolutely no intelligence from the front during the 7th, he telegraphed orders to the I. and II. armies (10.25 P.M.) to halt on the 8th, and impressed on Steinmetz the necessity of employing his cavalry to clear up the situation. The I. army had already begun the marches ordered by Steinmetz. It was now led back practically to its old bivouacs amongst the unburied dead. Prince Frederick Charles only conformed to Moltke's order with the III. and X. corps; the remainder executed their concentration towards the south and east. During the night of the 7th of August Moltke decided that the French army must be in retreat towards the Moselle and forthwith busied himself with the preparation of fresh tables of march for the two armies, his object being to swing up the left wing to outflank the enemy from the south. This work, and the transfer of headquarters to Homburg, needed time, hence no fresh orders were issued to either army, and neither commander would incur the responsibility of moving without any. The I. army therefore spent a fourth night in bivouac on the battlefield. But Constantin von Alvensleben, commanding the III. corps, a man of very different stamp from his colleagues, hearing at first hand that the French had evacuated St Avold, set his corps in motion early in the morning of the 10th August down the St Avold-Metz road, reached St Avold and obtained conclusive evidence that the French were retreating. Advance to the Moselle. During the 9th the orders for the advance to the Moselle were issued. These were based, not on an exact knowledge of where the French army actually stood, but on the opinion Moltke had formed as to where it ought to have been on military grounds solely, overlooking the fact that the French staff were not free to form military decisions but were compelled to bow to political expediency. Actually on the 7th of August the emperor had decided to attack the Germans on the 8th with the whole Rhine Army, but this decision was upset by alarmist reports from the beaten army of MacMahon. He then decided to retreat to the Moselle, as Moltke had foreseen, and there to draw to himself the remnants of MacMahon's army (now near Luneville). At the same time he assigned the executive command over the whole Rhine Army to Marshal Bazaine. This retreat was begun during the course of the 8th and 9th of August; but on the night of the 9th urgent telegrams from Paris induced the emperor to suspend the movement, and during the 10th the whole army took up a strong position on the French Nied.
