The English batteries played upon them with round shot, and, as they came near, with grape and canister; but the horsemen rode on, and at a steady trot arrived within forty yards of the English squares, when with a shout they galloped forward, and in a moment the whole of the advanced batteries of the allies were in their possession; for Wellington's orders had been that the artillerymen should stand to their guns till the last moment, and then run for shelter behind the squares. The French cavalry paused for a moment in astonishment at the sight that met their eyes. They had believed that the British were broken and disorganized, but no sooner had they passed over the slope than they saw the British and German squares bristling with bayonets and standing calm and immovable.

The artillery on both sides had ceased their fire, and a dead silence had succeeded the terrible din that had raged but a moment before. Then with a shout the cavalry again charged, but in no case did they dash against the hedges of bayonets, from which a storm of fire was now pouring. Breaking into squadrons they rode through the intervals between the squares and completely enveloped them; but Lord Uxbridge gathered the remains of the British cavalry together, charged them, and drove them back through the squares and down the hill. Receiving reinforcements the French again advanced, again enveloped the squares, and were again hurled back.

While this was going on the battle was still raging round Hougoumont and La Haye Sainte, against which a portion of Reille's division had advanced; but the Germans resisted as obstinately as did the guards, and as the French cavalry retired for the second time the infantry fell back, and for a time the slope of the English position was again clear of the enemy.

For a time the battle languished, and then Napoleon brought up thirty-seven fresh squadrons of cavalry, and these, with the remains of those who had before charged, rode up the slope. But although they swept on and passed the British squares, they could not succeed in shaking them. A body of horse, however, sweeping down toward the Dutch and Belgians at the end of the line, these at once marched off the field without firing a musket, and the brigade of cavalry with them galloped away at full speed.

The position was a singular one; and had Napoleon ordered his infantry to advance in the rear of the cavalry, the issue of the day might have been changed. In appearance the French were masters of the position. Their masses of cavalry hid the British squares from sight. The British cavalry were too weak to charge, and most of the guns were in the possession of the French; but the latter's infantry were far away, and after sustaining the fire of the squares for a long time, the cavalry began to draw off. Lord Uxbridge now endeavored to persuade the Cumberland Hanoverian Hussars, who had not so far been engaged, to charge; but instead of obeying orders they turned and rode off, and never drew bridle until they reached Brussels, where they reported that the British army had been destroyed.

Adams' brigade were now brought up from the reserve, and drove back the French infantry and cavalry who had come up to the top of the crest beyond Hougoumont. On the other side Ney sent a column against La Haye Sainte. The Germans made a gallant stand; but they were cut off from all assistance, outnumbered, and were altogether without ammunition; and although they defended themselves with their bayonets to the end, they were slain almost to a man, and La Haye Sainte was captured at last. But beyond this the French could not advance; and though column after column moved forward to the attack on the crest, they were each and all beaten back.

It was now nearly seven o'clock in the evening, and the Prussians were engaged at St. Lambert, Napoleon having detached Lobau's corps to arrest their progress. Their march had been a terrible one. They had to traverse country roads softened by the rain; the men were up to their ankles in mud, guns and carriages stuck fast, and it was not until after tremendous efforts that the leading squadron of their cavalry passed through the wood of Wavre and came in view of the battle that was raging. It was then past four o'clock, and another hour passed before any considerable number of infantry arrived. It was at this time Napoleon sent Lobau against them. He was able for a time to resist their advance; but as fresh troops came up from the rear the Prussians began to win their way forward, and Napoleon was obliged to send two more divisions of the Young Guard to check them.

He now saw that all was lost unless he could, before the whole of the Prussian army arrived, break down the resistance of the British. He therefore prepared for a final effort. Ney was to collect all his infantry, and, advancing past La Haye Sainte, to fall upon the center of the British line. The guard, who had hitherto been held in reserve, was to pass Hougoumont and attack the left center. The cavalry were to follow in support.

A cannonade even more heavy and terrible than before, for the guns of the reserve had been brought up, opened upon the British, and the squares were now melting away fast. But no reinforcements could be sent to them, for the whole of the British troops were now in action, and their allies had for the most part long before left the field.

Every gun was brought to the front, the remains of the cavalry gathered together as a reserve; and some of the Prussians now approaching the left, the cavalry there were brought to the center to aid in the defense of the threatened point. Just as these arrangements were completed the enemy advanced in tremendous force from the inclosure of La Haye Sainte, and with their fire so completely mastered that of the remnants of the infantry, that their light guns were brought up to within a hundred yards of the British line and opened with grape upon the squares. Two Hanoverian battalions were almost annihilated, the brigade of the German legion almost ceased to exist.
