The French staff apparently had designed a campaign in Upper Alsace and the Vosges, but the throwing of a brigade from Belfort across the frontier on the extreme right of their line on August 6 would seem to have been undertaken chiefly with a view of rousing patriotic enthusiasm. French aeroplane scouts had brought in the intelligence that only small bodies of German troops occupied the left bank of the Rhine. Therefore the opportunity was presented to invade the upper part of the lost province of Alsace--a dramatic blow calculated to arouse the French patriotic spirit. Since the Germans had expended hardly any effort in its defense, leaving, as it were an open door, it may have been part of the strategic idea of their General Staff to draw a French army into that region, with the design of inflicting a crushing defeat. Thus French resistance in the southern Vosges would have been weakened, the capture of Belfort, unsupported by its field army, a probability, and a drive beyond into France by the German forces concentrated at Neubreisach made triumphant. Doubtless the French General Staff fully grasped the German intention, but considered a nibble at the alluring German bait of some value for its sentimental effect upon the French and Alsatians. Otherwise the invasion of Upper Alsace with a brigade was doomed at the outset to win no military advantage. On August 7, 1914, the French dispersed a German outpost intrenched before Altkirch. Some cavalry skirmishing followed, which resulted in the French gaining possession of the city. As was to be expected, the citizens of Altkirch welcomed the French with enthusiasm. The following morning the French were permitted an uncontested advance to Muelhausen. That such an important manufacturing center as Muelhausen should have remained unfortified within striking distance of the French frontier, that the French entered it without being compelled to fire a shot, was a surprise to everyone with the probable exception of the German and French General Staffs. The citizens of Muelhausen repeated the joyous ovation bestowed on the French troops in Altkirch. The French uniform was hailed as the visible sign of deliverance from German dominion, and the restoration of the lost province to their kindred of the neighboring republic. The climax of this ebullition was reached in a proclamation issued by direction of General Joffre. "People of Alsace," it ran, "after forty years of weary waiting, French soldiers again tread the soil of your native country. They are the pioneers in the great work of redemption. What emotion and what pride for them! To complete the work they are ready to sacrifice their lives. The French nation with one heart spurs them forward, and on the folds of their flag are inscribed the magical names Liberty and Right. Long live France! Long live Alsace!"
