The open country now declared in favour of Charles. Tarragona, Tortosa, Gerona, Lerida, San Mateo, threw open their gates. The Spanish Government sent the Count of Las Torres with seven thousand men to reduce San Mateo. The Earl of Peterborough, with only twelve hundred men, raised the siege. His officers advised him to be content with this extraordinary success. Charles urged him to return to Barcelona; but no remonstrances could stop such a spirit in the midst of such a career. It was the depth of winter. The country was mountainous. The roads were almost impassable. The men were ill-clothed. The horses were knocked up.
The retreating army was far more numerous than the pursuing army.
But difficulties and dangers vanished before the energy of Peterborough. He pushed on, driving Las Torres before him. Nules surrendered to the mere terror of his name; and, on the fourth of February, 1706 he arrived in triumph at Valencia. There he learned that a body of four thousand men was on the march to join Las Torres. He set out at dead of night from Valencia, passed the Xucar, came unexpectedly on the encampment of the enemy, and slaughtered, dispersed, or took the whole reinforcement. The Valencians could scarcely believe their eyes when they saw the prisoners brought in.
In the meantime the Courts of Madrid and Versailles, exasperated and alarmed by the fall of Barcelona and by the revolt of the surrounding country, determined to make a great effort. A large army, nominally commanded by Philip, but really under the orders of Marshal Tesse, entered Catalonia. A fleet under the Count of Toulouse, one of the natural children of Lewis the Fourteenth, appeared before the port of Barcelona, The city was attacked at once by sea and land. The person of the Archduke was in considerable danger. Peterborough, at the head of about three thousand men, marched with great rapidity from Valencia. To give battle, with so small a force, to a great regular army under the conduct of a Marshal of France, would have been madness. The Earl therefore made war after the fashion of the Minas and Empecinados of our own time. He took his post on the neighbouring mountains, harassed the enemy with incessant alarms, cut off their stragglers, intercepted their communications with the interior, and introduced supplies, both of men and provisions, into the town. He saw, however, that the only hope of the besieged was on the side of the sea. His commission from the British Government gave him supreme power, not only over the army, but, whenever he should be actually on board, over the navy also. He put out to sea at night in an open boat, without communicating his design to any person. He was picked up several leagues from the shore, by one of the ships of the English squadron. As soon as he was on board, he announced himself as first in command, and sent a pinnace with his orders to the Admiral. Had these orders been given a few hours earlier, it is probable that the whole French fleet would have been taken. As it was, the Count of Toulouse put out to sea. The port was open. The town was relieved. On the following night the enemy raised the siege and retreated to Roussillon. Peterborough returned to Valencia, a place which he preferred to every other in Spain; and Philip, who had been some weeks absent from his wife, could endure the misery of separation no longer, and flew to rejoin her at Madrid.
At Madrid, however, it was impossible for him or for her to remain. The splendid success which Peterborough had obtained on the eastern coast of the Peninsula had inspired the sluggish Galway with emulation. He advanced into the heart of Spain.
Berwick retreated. Alcantara, Ciudad Rodrigo, and Salamanca fell, and the conquerors marched towards the capital.
Philip was earnestly pressed by his advisers to remove the seat of government to Burgos. The advance guard of the allied army was already seen on the heights above Madrid. It was known that the main body was at hand. The unfortunate Prince fled with his Queen and his household. The royal wanderers, after travelling eight days on bad roads, under a burning sun, and sleeping eight nights in miserable hovels, one of which fell down and nearly crushed them both to death, reached the metropolis of Old Castile. In the meantime the invaders had entered Madrid in triumph, and had proclaimed the Archduke in the streets of the imperial city.
Arragon, ever jealous of the Castilian ascendency, followed the example of Catalonia. Saragossa revolted without seeing an enemy.
The governor whom Philip had set over Carthagena betrayed his trust, and surrendered to the Allies the best arsenal and the last ships which Spain possessed.
