Confronting this gap, on the plateau behind the Meurthe, between Luneville and St. Die, with advanced posts about Ramberville, and a strong wide-stretching cordon of cavalry still further forward, the Third German Army, consisting of the 13th Würtemberg, and 1st and 2d Bavarian Army Corps, under the command of Leopold, Prince Regent of Bavaria, is to take up its position. The Prince is to make demonstrations from time to time to hold in position the French field-forces on its flanks and rear. If threatened in palpably overwhelming strength, the army has a line of retreat across the Middle Vosges open, striking back in the passes as it retires. Should the gap be judged practical by-and-by because of the withdrawal of the French field-forces to participate in the _mêlée_ in the interior of France, instructions how to act will, of course, be sent from the Imperial Headquarters. As soon as the mobilisation of the active army is complete, the Landwehr is to be mobilised with all speed to the last man, and got into readiness to reinforce the armies already in the field, for the Fatherland will be contending against heavy odds, and will need the devotion of all its sons. It should be said that the 2d (Pomeranian) Army Corps is retained in Germany for the protection of the northern coast. THE FRENCH PLAN OF CAMPAIGN. While these preparations have been made by Germany, France has not been idle. According to the latest telegrams from Paris, the original plan of campaign devised by the French Etat-major has undergone modification, now that it has become virtually certain that the main German advance is to be made through Belgium. The contingency that a contributory stroke may be made in that direction had, indeed, been in a measure provided for originally. To meet it four Army Corps were to take up an initial position in the fortress-bound triangle, La Fere-Soissons-Laon. Two were to be on the Meuse between Mouzon and Dun to confront a possible German entrance between Montmedy and Longwy. Three were allotted to the frontier on the extreme south-east, since Italy is a member of the Triple Alliance. The garrison of the Government of Paris was not to move. The remaining ten corps were destined for the eastern frontier from Verdun to Belfort.
