This was a mistake. The jubilant Spaniards, expecting to treat Napoleon as they had treated Dupont, had summoned the English to join them. Moore's orders were to assist them, and he prepared to obey, although he well knew what would be the consequences of Spanish hallucination. With one column he reached Salamanca on November thirteenth; the head of the other was at Astorga. His own division numbered only fifteen thousand men; the other was even smaller--ten thousand at the most. It was on that date that he learned of Napoleon's victories. Accordingly he halted to await the next move of the French. That move was against Madrid. Saragossa was besieged by Moncey, Lefebvre was thrown out to guard the right flank, and Ney to protect the left of the advancing columns; the march began on November twenty-eighth. The first obstacle was the mountain-range of Guadarrama, which had to be crossed by the pass of Somosierra. This defile was found to be strongly guarded; there were not only infantry stationed on the heights, but artillery also, sixteen guns being below the turn of the pass in a most advantageous position. In the early morning of the thirtieth the French infantry began to climb the cliffs on each side of the narrow gorge, and as the mists were heavy their movements were successfully concealed until the Spanish bivouacs were reached surprised, and dislodged. Simultaneously a regiment of Polish light horse was launched against the battery. Their charge was magnificent, and the gunners could fire only a single round before they were overpowered. By the ordinary breakfast hour the pass was free. On the evening of December second the whole army--infantry, cavalry, and artillery--was united on the heights of Chamartin before the gates of Madrid. Two days later, after a gallant resistance by its little garrison and the undaunted inhabitants, the city yielded to the superior strength of Napoleon, and proposed terms. After some parley these were accepted, but under the circumstances the Emperor felt that mildness must be seasoned by menace. There were disorders in the streets, incident to the new occupation by the French, and that fact he used as a plea to declare the capitulation null and the Spanish officers prisoners of war. Their men had escaped the day before.
