"Commandant," said Ségur, "let us go, it is the Emperor's wish; the honors will be ours; Poles advance. Vive l'Empereur!" Napoleon wished to teach his soldiers that with the Spaniards they must not consider danger, but drive them wherever found.

The smoke of the skirmishers on the side hills mingled with the thick fog and vapors of the morning, and under this veil the brave cavalry of the Guard led the way fearlessly and rushed up the ascent. A brilliant cavalry officer, General Montbrun, at this time somewhat out of favor with the Emperor, advanced at the head of the Polish light horse, a young troop of elite which Napoleon had formed at Warsaw that he might have all nations and costumes in his Guard. General Montbrun with those gallant young soldiers dashed at a gallop upon the cannon of the Spaniards, and in defiance of a horrible fire of musketry. The first squadron received a discharge which threw it into disorder, sweeping down thirty or forty men in the ranks; but those that followed, passing beyond the wounded, reached the pieces, cut down the gunners and took all the cannon.

As the rushing steeds passed the Spanish infantry the latter fired and then threw down their guns, abandoned their intrenchments and fled. The brave San Juan, covered with blood, having received several wounds, strove in vain to stop his soldiers, who fled to the right and to the left in the mountains, leaving colors, artillery, 200 wagons with stores and almost all the officers in the hands of the victors. By the time the Emperor reached the top not only was the French flag found floating over Buitrago, but Montbrun's cavalry was pursuing the routed Spanish a league beyond the town.

Napoleon was delighted to have proved to his generals what the Spanish insurgents were, what his soldiers were, and in what estimation both were to be held, and to have overcome an obstacle which some had seemed to think extremely formidable. The Poles had about fifty men killed or wounded. That evening Napoleon complimented and rewarded the survivors and included in the distribution of his favors M. Philippe de Ségur who had received several shot wounds in this charge; he also destined him to carry to the Legislative Body at Paris the colors taken at Somosierra and appointed Montbrun general of division.

On the morning of the 2nd three divisions of French cavalry made their appearance on the high ground to the north-west of the capital. The inhabitants of Madrid for eight days had been preparing to resist an invasion. Six thousand regular troops were within the town, and crowds of citizens and of the peasantry of the adjacent country were in arms with them. The pavement had been taken up, the streets barricaded, the houses on the outskirts loop-holed and occupied by a strong garrison. Many persons, suspected of adhering to the side of the French, were put to death, and amid the ringing of the bells of churches and convents, a general uprising for all means of defense was in operation when the French cavalry appeared.

The day was the anniversary of Napoleon's coronation and of the battle of Austerlitz, and for the Emperor as well as his soldiers a superstition was attached to that memorable date. The fine cavalry, on beholding its glorious chief, raised unanimous acclamations, which mingled with the shouts of rage sent up by the Spaniards on seeing the French at their portals.

At noon the town was summoned to open its gates. The young officer carrying the message barely escaped with his life, the mob being determined to massacre him. Only the interference of the Spanish regulars saved his life by snatching him out of the hands of the assassins. The Junta directed a Spanish general to convey a negative answer to the summons of the French. When sent back he was assured that firing would commence immediately, although told that in resisting they would only expose a population of women, and children and old men to the slaughter, and was informed that the city could not hold out long against the French army.
