The two armies first came together on August 2d, near Saarbrück, on the frontier line of the hostile kingdoms. It was the one success of the French, for the Prussians, after a fight in which both sides lost equally, retired in good order. This was proclaimed by the French papers as a brilliant victory, and filled the people with undue hopes of glory. It was the last favorable report, for they were quickly overwhelmed with tidings of defeat and disaster. Weissenburg, on the borders of Rhenish Bavaria, had been invested by a division of MacMahon's army. On August 4th the right wing of the army of the Crown Prince Frederick attacked and repulsed this investing force after a hot engagement, in which its leader, General Douay, was killed, and the loss on both sides was heavy. Two days later occurred a battle which decided the fate of the whole war, that of Worth-Reideshofen, where the army of the crown prince met that of MacMahon, and after a desperate struggle, which continued for fifteen hours, completely defeated him, with very heavy losses on both sides. MacMahon retreated in haste towards the army at Chalons, while the crown prince took possession of Alsace, and prepared for the reduction of the fortresses on the Rhine, from Strasburg to Belfort. On the same day as that of the battle of Worth, General Steinmetz stormed the heights of Spicheren, and, though at great loss of life, drove Frossard from those heights and back upon Metz. [=Occupation of Alsace and Lorraine=] The occupation of Alsace was followed by that of Lorraine, by the Prussian army under King William, who took possession of Nancy and the country surrounding on August 11th. These two provinces had formerly belonged to Germany, and it was the aim of the Prussians to retain them as the chief anticipated prize of the war. Meanwhile the world looked on in amazement at the extraordinary rapidity of the German success, which, in two weeks after Napoleon left Paris, had brought his power to the verge of overthrow. Towards the Moselle River and the strongly fortified town of Metz, 180 miles northeast of Paris, around which was concentrated the main French force, all the divisions of the German army now advanced, and on the 14th of August they gained a victory at Colombey-Neuvilly which drove their opponents back from the open field towards the fortified city. [=The Situation at Metz=] It was Moltke's opinion that the French proposed to make their stand before this impregnable fortress, and fight there desperately for victory. But, finding less resistance than he expected, he concluded, on the 15th, that Bazaine, in fear of being cooped up within the fortress, meant to march towards Verdun, there to join his forces with those of MacMahon and give battle to the Germans in the plain.
