Napoleon’s Grand army for the invasion of Belgium was made up of the First, Second, Third, Fourth and Sixth Corps d’Armée; four Corps of Reserve Cavalry; and the Imperial Guard; a total of 116,124 men. The First Corps, under d’Erlon, consisted of the First, Second, Third, and Fourth Infantry Divisions, and the First Light Cavalry Division. In the early part of June, the Corps was stationed at Lille. The Second Corps, under Reille, consisted of the Fifth, Sixth, Seventh and Eighth Infantry Divisions, and the Second Light Cavalry Division. This Corps was quartered at Valenciennes. The Third Corps, Vandamme’s, comprised the Ninth, Tenth, and Eleventh Infantry Divisions, and the Third Light Cavalry Division, and was stationed at Mézières. The Fourth Corps, Gérard’s, was composed of the Twelfth, Thirteenth and Fourteenth Infantry Divisions, and the Seventh Light Cavalry Division. The Corps was stationed in Metz, Longwy, and Thionville. The Sixth Corps, Lobau’s, was made up of the Nineteenth, Twentieth, and Twenty-first Infantry Divisions; it was stationed at Laon. Grouchy commanded the four Corps of Reserve cavalry; these First, Second, Third, and Fourth Cavalry Corps were commanded by Pajol, Excelmans, Kellermann, and Milhaud respectively; they were mostly stationed between the river Aisne and the frontier. The Imperial Guard consisted of twelve regiments of infantry, two regiments of heavy cavalry, three of light cavalry, and thirteen batteries of artillery. The Guard left Paris for Avesnes early in June. To the First and Second Corps d’Armée were attached six batteries; to the Third and Fourth, five batteries; and to the Sixth, four batteries of artillery. This army was the best, in point of courage, warlike spirit, and devotion to himself, that Napoleon ever led. But the men were without discipline, and distrusted their leaders. Napoleon’s generals were not the best that had ever served under him. Ney was a tried veteran, the “bravest of the brave,” but he had just come over to Napoleon from Louis XVIII. Grouchy had never held an independent command. It is remarkable that _both_ Ney and Grouchy should have failed Napoleon in this, his last, campaign; but neither were fitted to the great trusts committed to them. Napoleon himself was not the same man who had beaten back the Allies a year previously at Montmirail, Montereau, and Champaubert, but he was still a master of strategy and the strongest man of France. _The First Movements of the French._ Napoleon began his concentration early in June. He moved the First Corps from Lille to Avesnes; the Second from Valenciennes to Maubeuge; the Third from Mézières to Chimay; the Fourth from Thionville to Rocroi; the Sixth from Laon to Avesnes; and the Guard from Paris to Avesnes.
