Marshal Soult's 13:00 letter ordering Grouchy to move quickly to join Napoleon and to attack Bülow arrived after 18:00. Grouchy at once began gathering additional divisions and headed to Limal, arriving at 23:00, where he found that Pajol's cavalry had forced the bridge there. Prussian scouting cavalry noticed the strong French columns moving to Limal and the Prussian 12th Brigade moved covering forces to the area. The Prussians made a bayonet charge in an attempt to retake Limal, but without success. Night closed the major actions of the battle of Wavre, although outposts fired on each other all night.
