Things are accomplished in war which do not fit into the framework of its largest stories, and tend, therefore, to be lost. Overshadowed by the great story of Waterloo, the work which Lord Uxbridge and his Horse did on that afternoon of Saturday the 17th of June is too often forgotten.
The ability and the energy displayed were equal.
The first deployment to meet the French advance, the watching of the retirement of Wellington's main body, the continual appreciation of ground during a rapid and dangerous movement and in the worst of weather, the choice of occasional artillery positions--all these showed mastery, and secured the complete order of Wellington's retreat.[15]
The pursuit was checked at its most important point (where the French had to cross the river Dyle at Genappe) by a rapid deployment of the cavalry upon the slope beyond the stream, a rapid unlimbering of the batteries in retreat, and a double charge, first of the Seventh Hussars, next of the First Life Guards.
These charges were successful, they checked the French, and during the remainder of the afternoon the pursuit to the north of the Dyle slackened off until, before darkness, it ceased altogether.
Indeed, there was by that time no further use in it. The mass of Wellington's army had reached, and had deployed upon, that ridge of the Mont St Jean where he intended to turn and give battle. They were in a position to receive any immediate attack, and the purposes of mere pursuit were at an end.
Facing that ridge of the Mont St Jean, where, at the end of the afternoon and through the evening, Wellington's troops were already taking up their positions, was another ridge, best remembered by the name of a farm upon its crest, the "Belle Alliance." This ridge formed the natural halting-place of the pursuers. From the height above Genappe to the ridge of the Belle Alliance was but 5000 yards; and if a further reason be quoted for the cessation of the pursuit and the ranging into battle array of either force, the weather will provide that reason.
The soil of all these fields is of a peculiar black and consistent sort, almost impassable after a drenching rain. The great paved high road which traverses it was occupied and encumbered by the wheeled vehicles and by the artillery. A rapid advance of infantry bodies thrown out to the right and left of the road, and so securing speed by parallel advance, was made impossible by mud, and the line grew longer and longer down the main road, forbidding rapid movement. From mud, that "fifth element in war" (as Napoleon himself called it), Wellington's troops--the mass of them at least--had been fairly free. They had reached their positions before the downpour. Only the cavalry of the rearguard and its batteries had felt the full force of the storm. Dry straw of the tall standing crops had been cut on the ridge of the Mont St Jean, and the men of Wellington's command bivouacked as well as might be under such weather.
