Actions of the III Bavarian Corps in Lorraine 1914.
On 20 August, 1914, the German Sixth and Seventh Armies began their advance from the general area: Metz, Saarburg, and the Vosges, towards the French First and Second Armies. The Germans believed that at least an effort of double envelopment should be made. The situation seemed especially adapted for such a maneuver. During the last few days the French First and Second Armies had assembled the mass of their forces, between Saarburg and Mörchingen (Morhange), in order to oppose at the west slope of the Vosges Mountains an attack of the Germans.
The French flanks were weak, especially their left flank, which was exposed from Nancy to Mörchingen (Morhange). The German high command decided to have the III Bavarian Corps move quickly via Delm on Chateau Salins while the mass of the French forces were to be contained in the vicinity of Mörchingen. This Corps had been intentionally concealed in rear of the Rotte, north of the Wallersberg. The protection of the right flank of the corps was the mission of the 33d Reserve Division, which was to move forward against an enemy advance on Delm and prevent an enemy attack from the direction of Nancy.
The III Bavarian Corps began the advance against -the enemy at 5:00 AM, 20 August, from both sides of the Wallersberg; the 5th Bavarian Division on the left and the 6th Bavarian Division on the right. No enemy had been seen in front of this Corps for some time. During the previous evening only some weak French advance detachments had been observed in the vicinity of Lixingen.
Not knowing where the French would offer any resistance, both divisions refrained from making preliminary contacts. However, the zones or advance had been clearly and definitely designated. These measures undoubtedly prevented undesirable surprise. In addition, phase lines for the advance were also prescribed.
