The Right Column, under GROUCHY, comprising the Cavalry Corps of PAJOL and EXCELMANS, moved by its right, and took post, as did also the Light Cavalry Division under Lieutenant General MAURIN, belonging to the Fourth _Corps d'Armée_, on the right of GÉRARD, and showing front towards the Villages of Tongrines, Tongrenelle, Boignée, and Balatre. GROUCHY disposed this Cavalry so as to protect GÉRARD from any attempt which the Prussians might make to debouch in his rear from Mont Potriaux or Tongrenelle; as also to watch any hostile movements on their Left, and to divert their attention from the Centre. PAJOL's Corps, which was formed on the Right, detached along the cross road which leads to Namur. The Villages of Boignée and Balatre being situated on the French side of the valley, and occupied by Prussian Infantry, GROUCHY was supplied with two Battalions from GÉRARD's Corps. The 1st and 2nd Squadrons of the 3rd Kurmark Landwehr Cavalry belonging to THIELEMANN's Corps, which had been posted in advance, upon the Fleurus road, retired skirmishing until they reached the barrier at the Bridge, whither they were pursued by the French Cavalry. Here, however, the latter were checked and driven off by the 3rd Battalion of the 4th Kurmark Landwehr, belonging to Colonel Luck's Brigade. The Imperial Guard and MILHAUD's _Cuirassiers_ were halted in reserve, the former on the left, and the latter on the right, of Fleurus. The numerical strength of the French Emperor's forces prepared to engage with the Prussian Army amounted to:-- Infantry, 43,412 Cavalry, 12,614 Artillery, 6,856 ------ Total, 62,882 men, with 204 guns. If to this we add LOBAU's Corps, which was on the march from Charleroi, the total amount of available force was:-- Infantry, 51,564 Cavalry, 12,614 Artillery, 7,788 ------ Total, 71,966 men, with 242 guns. The Prussian Army in the Field amounted to:-- Infantry, 73,040 Cavalry, 8,150 Artillery, 3,437 ------ 84,617 Deduct loss of first Corps on 15th June, 1,200 ------ Total, 83,417, with 224 guns. As soon as the direction of the Enemy's movements for attack became sufficiently manifest, BLÜCHER made such further disposition of his force as appeared to him requisite to meet that attack.
