Louis XIV. ordered the next campaign to be commenced by his troops on a scale of grandeur and with a boldness of enterprise, such as even Napoleon's military schemes have seldom equalled. On the extreme left of the line of the war, in the Netherlands, the French armies were to act only on the defensive. The fortresses in the hands of the French there, were so many and so strong that no serious impression seemed likely to be made by the Allies on the French frontier in that quarter during one campaign; and that one campaign was to give France such triumphs elsewhere as would (it was hoped) determine the war. Large detachments were, therefore, to be made from the French force in Flanders, and they were to be led by Marshal Villeroy to the Moselle and Upper Rhine. The French army already in the neighbourhood of those rivers was to march under Marshal Tallard through the Black Forest, and join the Elector of Bavaria and the French troops that were already with the Elector under Marshal Marsin. Meanwhile the French army of Italy was to advance through the Tyrol into Austria, and the whole forces were to combine between the Danube and the Inn. A strong body of troops was to be despatched into Hungary, to assist and organize the insurgents in that kingdom; and the French grand army of the Danube was then, in collected and irresistible might, to march upon Vienna, and dictate terms of peace to the Emperor. High military genius was shown in the formation of this plan, but it was met and baffled by a genius higher still.
