Napoleon, finding Blucher gone, turned his attentions to Wellington, expecting to find him still at Quatre Bras; but, as we have said, the Duke was now on his retreat to Waterloo. Buonaparte dispatched his cavalry in hot haste after him, and they came up with his rear at Genappe, where the British had to pass through a narrow street, and over a narrow bridge across the Dyle. There the French came with such impetus that they threw the light cavalry into confusion; but the heavy dragoons soon rode back, and drove the French with such effect before them, that they made no further interruption of the march. Without an enemy at their rear the march was repugnant enough to the soldiers. British soldiers abominate anything like a retreat. They had heard of the defeat of the Prussians at Ligny; and this retrograde movement looked too much of the same character to please them. Besides, it was raining torrents all the way; and they had to tramp across fields up to the knees in mud. At five in the evening, however, the Duke commanded a halt, and took up his position on ground which thenceforth was to be immortal. He was on the field of Waterloo! Long before this the position had attracted his attention, and he had thought that had he to fight a battle anywhere in that part of the country, it should be on that ground. About two miles beyond the village of Waterloo, which has been chosen to bear the name of this famous battle, and about a mile beyond the hamlet of Mont St. Jean, there stretches across the Charleroi road a ridge of some elevation. On this Wellington posted his army, his left extending to a hamlet called La Haye, and his right across the Nivelles road, to a village and ravine called Braine Merbes. These two roads united in the highway to Brussels, just behind the hamlet of Mont St. Jean, and close behind the centre of Wellington's position was the farm of Mont St. Jean; a little below his centre, on the Charleroi road or causeway, leading through Genappe to Quatre Bras, whence they had come, was another farmhouse, called La Haye Sainte. On Wellington's right, but down in the valley near the Nivelles road, lay an old château, with its walled orchard, and a wood beyond it, called Hougomont--a contraction of Château-Gomont. Below this position ran a valley, and from it ascended opposite other rising grounds, chiefly open cornfields; and along this ascent, at about half a mile distant, Buonaparte posted his army, shutting in by his right the château of Hougomont, and commanding it from the high ground. Nearly opposite to Wellington's centre stood a farmhouse, enclosed in its orchards, called La Belle Alliance. There Buonaparte took his stand, and kept it during all the fight--each commander being able to view the whole field. Close behind Wellington the ground again descended towards Mont St. Jean, which gave a considerable protection to his reserves, and kept them wholly out of the observation of the French.
