“The loss of the enemy must have been very great, if we may judge from the number of standards we have taken from him, and from the retrograde movements which he made; ours cannot be calculated till after troops shall have been collected. Before the disorder broke out, we had already experienced a very considerable loss, particularly in our cavalry, so fatally, though so bravely engaged. Notwithstanding these losses, this brave cavalry constantly kept the position it had taken from the English, and only abandoned it when the tumult and disorder of the field of battle forced it. In the midst of the night, and the obstacles which encumbered their route, it could not preserve its own organization. “The artillery has, as usual, covered itself with glory. The carriages belonging to the head-quarters remained in their ordinary position; no retrograde movement being judged necessary. In the course of the night they fell into the enemy’s hands. “Such has been the issue of the battle of Mont-St.-Jean, glorious for the French armies, and yet so fatal.” MARSHAL GROUCHY’S OFFICIAL REPORT TO NAPOLEON. “DINANT, June 20th, 1815. “It was not till after seven in the evening of the 18th of June, that I received the letter of the duke of Dalmatia, (Soult,) which directed me to march on St.-Lambert, and to attack general Bulow. I fell in with the enemy as I was marching on Wavre. He was immediately driven into Wavre, and general Vandamme’s corps attacked that town, and was warmly engaged. The portion of Wavre, on the right of the Dyle, was carried: but much difficulty was experienced in debouching, on the other side; general Gérard was wounded by a ball in the breast, whilst endeavouring to carry the mill of Bierge, in order to pass the river, but where he did not succeed; and lieutenant-general Aix had been killed in the attack on the town. In this state of things, being impatient to cooperate with your Majesty’s army on that important day, I detached several corps to force the passage of the Dyle and march against Bulow. The corps of Vandamme, in the mean time, maintained the attack on Wavre, and on the mill, whence the enemy showed an intention to debouch, but which I did not conceive he was capable of effecting. I arrived at Limal, passed the river, and the heights were carried by the division of Vichery and the cavalry. Night did not permit us to advance farther, and I no longer heard the cannon on the side where your Majesty was engaged.
