It was in the last week of February that the news reached the Earl of Peterborough that Marshal Tesse had left Saragossa, and was marching toward Lerida. This was two days after the unsuccessful attempt to surprise the enemy's camp near Alcira; and, menaced as Valencia was by a force greatly superior to his own, he could not leave the city, which in his absence would speedily have succumbed to the attack of Las Torres. He walked quickly up and down his room for some minutes and then said:

"Captain Stilwell, I cannot leave here myself, but I will send you to the Marquis of Cifuentes. You have shown the greatest activity and energy with me, and I do not doubt that you will do equally well when acting independently. I will give you a letter to the marquis, saying that you are one of my most trusted and valued officers, and begging him to avail himself to the fullest of your energy and skill. I shall tell him that at present I am tied here, but that when the enemy reach Barcelona, I shall at all hazards march hence and take post in their rear and do what I can to prevent their carrying on the siege. In the mean time I beg him to throw every obstacle in the way of their advance, to hold every pass to the last, to hang on their rear, attack baggage trains, and cut off stragglers. He cannot hope to defeat Tesse, but he may wear out and dispirit his men by constant attacks. You speak Spanish fluently enough now, and will be able to advise and suggest. Remember, every day that Tesse is delayed gives so much time to the king to put Barcelona in a state of defense. With my little force I cannot do much even when I come. The sole hope of Barcelona is to hold out until a fleet arrives from England. If the king would take my advice I will guarantee that he shall be crowned in Madrid in two months; but those pig headed Germans who surround him set him against every proposition I make. You had better start tonight as soon as it gets dark, and take a mounted guide with you who knows the country thoroughly.
