The progress of the Prussians and the famous manifesto of Brunswick contributed to hasten this movement. Prussia had joined Austria and the German princes against France. This coalition, to which the court of Turin joined itself, was formidable, though it did not comprise all the powers that were to have joined it at first. The death of Gustavus, appointed at first commander of the invading army, detached Sweden; the substitution of the count d'Aranda, a prudent and moderate man, for the minister Florida- Blanca, prevented Spain from entering it; Russia and England secretly approved the attacks of the European league, without as yet co-operating with it. After the military operations already mentioned, they watched each other rather than fought. During the interval, Lafayette had inspired his army with good habits of discipline and devotedness; and Dumouriez, stationed under Luckner at the camp of Maulde, had inured the troops confided to him by petty engagements and daily successes. In this way they had formed the nucleus of a good army; a desirable thing, as they required organization and confidence to repel the approaching invasion of the coalesced powers. The duke of Brunswick directed it. He had the chief command of the enemy's army, composed of seventy thousand Prussians, and sixty-eight thousand Austrians, Hessians, or emigrants. The plan of invasion was as follows:-- The duke of Brunswick with the Prussians, was to pass the Rhine at Coblentz, ascend the left bank of the Moselle, attack the French frontier by its central and most accessible point, and advance on the capital by way of Longwy, Verdun, and Châlons. The prince von Hohenlohe on his left, was to advance in the direction of Metz and Thionville, with the Hessians and a body of emigrants; while general Clairfayt, with the Austrians and another body of emigrants, was to overthrow Lafayette, stationed before Sedan and Mézieres, cross the Meuse, and march upon Paris by Rheims and Soissons. Thus the centre and two wings were to make a concentrated advance on the capital from the Moselle, the Rhine, and the Netherlands. Other detachments stationed on the frontier of the Rhine and the extreme northern frontier, were to attack our troops on these sides and facilitate the central invasion.
