Of these facts he was ignorant, but the letters that he received from Lord William Bentinck and Colonel Graham, exposing the folly of the Spanish generals, reached him. On the 11th he crossed the frontier of Spain, marching to Ciudad-Rodrigo. On that day Blake was finally defeated, and one of the other armies completely crushed and dispersed. These events left a large French army free to act against the British. Sir John Moore, however, did not hear of this until a week later. He knew, however, that the situation was serious; and after all the reports of Spanish enthusiasm, he was astonished to find that complete apathy prevailed, that no effort was made to enroll the population, or even to distribute the vast quantity of British muskets stored up in the magazines of the cities. The general arrived at Salamanca with 4,000 British infantry. The French cavalry were at Valladolid, but three marches distant. On the 18th more troops had arrived, and on the 23d 12,000 infantry and six guns were at Salamanca. But Moore now knew of the defeat of Blake, and that the French army that had crushed him was free to advance against Salamanca. But he did not yet know of the utter dispersal of the Asturian army, or that the two armies of Castanos and Palafox were also defeated and scattered beyond any attempt at rallying, and that their conquerors were also free to march against him. Although ignorant of the force with which Napoleon had entered Spain, and having no idea of its enormous strength, he knew that it could not be less than 80,000 men, and that it could be joined by at least 30,000 more. His position was indeed a desperate one. Baird was still twenty marches distant, his cavalry and artillery still far away. It would require another five days to bring the rear of his own army to Salamanca, as only a small portion could come forward each day, owing to want of transport; and yet, while in this position of imminent danger, the Spanish authorities, through Mr. Frere and other agents, were violently urging an advance to Madrid. General Moore was indeed in a position of imminent danger; but the lying reports as to the strength of the Spanish army induced him for a moment to make preparations for such a movement. When, however, he learned the utter overthrow and dispersal of the whole of the Spanish armies, he saw that nothing remained but to fall back, if possible, upon Portugal.
