It was a fatal error, and, too late, Napoleon saw it. It lost the day, for, at this critical period, the battle was drawn. The English could not advance, and, in consequence of the Emperor's having despatched ten thousand men to hold Bulow, the Prussian general, in check, the French were not in a position to follow up any advantage the cavalry charge might give them.

St. Just joined himself to General Kellermann's command and charged with them. They rushed off at a gallop, the thousands of hoofs making the ground shake beneath them. Again and again they dashed with desperate valor at the English infantry, but could make no permanent impression; frequently they broke the line opposed to them; but the stubborn Englishmen had a valor equal to their own, and always rallied, closing up their ranks as fast as they were broken. More and more furiously did the Frenchmen fight, but it was all of no avail. They had made their final throw, and it had proved a blank. Their loss of men was fearful, and, before reinforcements could be hurried up, Blucher, with his Prussians had come up.

This was the turning point of the day. From that moment, the French case was hopeless, and they had to admit defeat. The Retreat was sounded; but soon all order was abandoned, and it became a rout, and the cry of "sauve qui peut" went up. The worsted French scattered pell-mell in all directions.

St. Just, forced back in the rout that followed this welcome and almost indispensable accession to the strength of the "thin red line," of English, once more regained the Emperor's side.

Night was advancing and the Emperor could no longer direct his routed troops. It was too dark for practical orders either to be given, or, if given, carried out. But he still lingered, and was only forced away in the general rush, St. Just and two or three others with him.

Across that ghastly field they rode; and what a ride! Every now and then some bivouac fire, not yet expired, would flicker up in the darkness and show the flying Emperor to the host of wounded that bestrewed his path. Many of the poor creatures, when they recognized him, would raise themselves upon their elbows and, even while they groaned with pain, would faintly cheer, then sink back exhausted by their effort, only to be trampled to death alike by friend and foe in the mad flight of pursuer and pursued.

On and on and on the little party rode, wearied and dejected, almost without a word. A short halt was made at Genappe, merely to obtain fresh horses. At one o'clock on the morning of the 19th they reached Quatre Bras. Here they remained, and rested for an hour, and the Emperor despatched orders to try to check the rout and collect the scattered fragments of the army. Also St. Just says, to inform General Grouchy of their defeat.

At dawn the journey was resumed by way of Laon, and thence, by rapid stages, to Paris.

CHAPTER VI.

It was the 28th of June. Much had happened in the ten days that had elapsed since the battle of Waterloo. Napoleon had returned to Paris; had found both the Chamber of Peers and the Chamber of Representatives determined no longer to retain him as the ruler of the country; had abdicated in consequence; and was now on his way to Rochefort with the intention of escaping to the United States.
