Throughout the 13th, the German Corps, horse and foot, sprang forward, displaying that alacrity and hardihood which had marked their conduct from the outset of the war. The Dragoon brigade of the Guard swooped down upon Dieulouard, and finally sundered the direct railway communication between Chalons and Metz. Two other cavalry brigades, forming the 5th Division, entered Pont à Mousson early in the morning, and were followed by half the 10th Corps from Delme. In order to hide, as far as possible, the movements of the Second Army, an entire division of cavalry, the 6th, was employed; one brigade extending from Courcelles sur Nied, to Borny on the Moselle, and the other posted at Verny supporting the front line, and linked itself by patrols to the 5th at Pont à Mousson. The 1st Division of Cavalry, during the forenoon, crossed the Nied at Pange, and occupied the villages to the right and left, so that a continuous line of mounted men stretched from the Nied to the Moselle. Behind this barrier, the several Corps toiled forward in full security. At the close of the day, however, only one-half the 10th Corps was over the Moselle, the other moiety being one march to the rear; the head of the 3rd Corps stood at Buchy; the 9th at Herny; the 12th at Chemery; the 2nd, now complete, at St. Avold; the Guard at Lémoncourt, and the 4th at Chateau Salins. By this time, the Third Army, except the 6th Corps, and the Baden Division which had been directed upon Strasburg, had made its way through the defiles of the Vosges, had emerged into the valley of the Upper Saar, and was, therefore, in direct communication with the Second Army; so that the German host occupied a wide region extending from Sarrebourg to villages in front of Metz; yet at the vital points the Corps stood near enough to support each other should it be necessary to assemble on a field of battle. The passage of the Vosges had been obstructed only by nature and the forts of Bitsche and Phalsbourg. These were turned, and the hardships of cross roads and restricted supplies had been overcome. The divisions trickled through the valleys on a broad front, gathering up as they touched the Saar and the country of lakes about Fenestrange. As Phalsbourg did not command the railway, that important highway fell into the hands of the Germans. The tunnels in the Zorn valley west of Saverne had not been destroyed, and the whole line was complete, yet it could not be used for the transport of troops and stores until a later period. On the 13th, when the First Army was closing in on the French outside Metz, and the Second heading for the Moselle, the Third quitted the Upper Saar, and, once more expanding, approached on a broad front the valley of the Meurthe. During the next day, when their comrades were hotly engaged with the enemy, they reached the banks of that stream, and their forward cavalry rode into the streets of Lunéville and Nancy, the old capital of Lorraine.
