in that quarter. It simply announced that the Prussian outposts in front of Charleroi were engaged. It might be the commencement of a real attack in this direction, but it might also be a diversion in favour of an attack in some other direction, such as Mons. Not long after 15:00, William, The Prince of Orange arrived in Brussels, and informed Wellington that the Prussian outposts had been attacked and forced to fall back.

At the same time an express was despatched to Major General Dörnberg, requiring information concerning any movement that might have been made on the part of the French in the direction of Mons. Wellington ordered the following movements: Upon the left of the Anglo-allied army, which was nearest to
