The assembling of the First Army appeared to be less threatened, as its route lay through neutral territory, and was protected by the garrisons of Trèves, Saarlouis, and Saarbrücken, the German outposts on the Saar. The First Army, 50,000 strong, was concentrated at Wadern, in the first days of August. The Second Army, which meanwhile had been increased to a strength of 194,000 men, had pushed forward its cantonments to Alsenz-Günnstadt, at the termination of the Haardt Mountains, a position which had been thoroughly reconnoitered by an officer of the Staff, and where the troops might boldly await an attack. The 5th and 6th Cavalry Divisions were reconnoitering the country in front. The regiments and squadrons of the Third Army were still gathering on both banks of the Rhine. The French so far had made no serious attempt at Saarbrücken; Lieutenant-Colonel Pestel was able to successfully withstand their petty attacks with one battalion and three squadrons of cavalry. It had meanwhile been observed that the French were moving further to the right, toward Forbach and Bitsch, which seemed to indicate that the two French Corps, known to be drawn up at Belfort and Strassburg, might purpose crossing the Rhine and marching on the Black Forest. It was therefore of very great importance to set the Third Army moving at the earliest opportunity, first to protect the right bank of the Upper Rhine by an advance on the left; secondly to cover the progress of the Second Army towards that point. A telegraphic order to that effect was dispatched on the evening of July 30th, but the General in command of the Third Army Corps desired to wait for the arrival of the Fourth and its baggage train. In spite of this hesitancy the Second Army was ordered to proceed towards the Saar, where the French were showing much uneasiness. The time had gone by when they might have taken advantage of their over-hasty mobilization; the condition of the men had prohibited any action. France was waiting for news of a victory; something had to be done to appease public impatience, so, in order to do something, the enemy resolved (as is usual under such circumstances) on a hostile reconnoissance, and, it may be added, with the usual result. On August 2d three entire Divisions were sent forward against three battalions, four squadrons, and one battery in Saarbrücken. The Emperor himself and the Prince Imperial watched the operations. The IIId Corps advanced on Völklingen, the Vth on Saargemünd, the IId on Saarbrücken. The Germans evacuated Saarbrücken after a gallant defence and repeated sorties, but the French did not cross the Saar. They may have convinced themselves that they had wasted their strength by hitting in the air, and had gained no information as to the resources and position of the enemy.
