The means of mobilizing the North-German army had been reviewed year by year, in view of any changes in the military or political situation, by the Staff, in conjunction with the Ministry of War. Every branch of the administration throughout the country had been kept informed of all it ought to know of these matters. The Berlin authorities had likewise come to a confidential understanding with the army chiefs of the South-German states on all important points. It had been conceded that Prussia was not to be reckoned on for the defence of any particular point, as the Black Forest, for instance; and it was decided that the best way of protecting South Germany would be by an incursion into Alsace across the central part of the Rhine; which could be backed up by the main force assembled at that point. The fact that the Governments of Bavaria, Würtemberg, Baden, and Hesse, denuding their own countries as it were, were ready to place their contingents under the command of King William proves their entire confidence in the Prussian generals. As soon as this understanding was arrived at the other preparations could be made. The orders for marching, and traveling by rail or boat, were worked out for each division of the army, together with the most minute directions as to their different starting points, the day and hour of departure, the duration of the journey, the refreshment stations, and place of destination. At the meeting-point cantonments were assigned to each Corps and Division, stores and magazines were established; and thus, when war was declared, it needed only the Royal signature to set the entire apparatus in motion with undisturbed precision. There was nothing to be changed in the directions originally given; it sufficed to carry out the plans prearranged and prepared. The mobilized forces were divided into three independent armies on a basis worked out by the general of the Prussian staff. The First Army, under the command of General von Steinmetz, consisted of the VIIth and VIIIth Corps, and one division of cavalry; 60,000 men all told. It was ordered to encamp at Wittlich and form the right wing. The Second Army, under the command of Prince Frederick Charles, was 131,000 strong, and constituted the central army. It consisted of the IIId, IVth, and Xth Corps of Guards, and two divisions of cavalry. Its meeting-point was in the vicinity of Homburg and Neunkirchen. The Third Army, under the command of the Crown Prince of Prussia, was to form the left wing, near Landau and Rastat, a strength of about 130,000 men. It consisted of the Vth and XIth Prussian, and the Ist and IId Bavarian Corps, the Würtemberg and the Baden Field Divisions, and one division of cavalry. The IXth Corps, consisting of the 18th and the Hesse divisions, was united with the XIIth Royal Saxon Corps to form a reserve of 60,000 men, and was encamped before Mayence, to reinforce the Second Army, which was thus brought up to the strength of 194,000 men.
