THREE:In June Massena advanced, and laid siege to Ciudad Rodrigo. This was almost within sight of Wellington's lines. The town was defended by a Spanish garrison, and Wellington was called upon to co-operate by attacking the besiegers. This he offered to do if Romana would undertake to prevent the march of Regnier from Estremadura on his rear the while; but Romana would not undertake to maintain himself against Regnier if the British force under General Hill crossed the Tagus. Wellington, whose object was to defend Portugal and not Spain, therefore lay still; and the Spaniards, after a brave defence, were compelled to capitulate on the 10th of July. Then there was a wild cry of indignation raised against Wellington by the Spaniards, and even by his own officers, that he should see a place taken from our allies, under his very eyes, and not attempt to relieve it. The French taunted him with it in the Moniteur, and regarded it as a great sign of his weakness. But none of these things moved Wellington. He knew what he had to dowhich was to defend Portugaland he had made his plans for doing it; but this was not by exposing his small army in any situation to which the Spanish chose to call him, while, at the same time, they declined to co-operate with him. He soon had the division of Marshal Ney upon his outposts, where he fell in with our light division under General Craufurd. Wellington had ordered that, on attack, Craufurd should retire on the main body in order, because he did not wish to reduce his small numbers in skirmishes, but to reserve them for favourable occasions; but Craufurd, being hotly pursued, turned and gave the French a severe rebuff, killing and wounding above one thousand of Massena's men. Craufurd, having driven the French back three times, made a masterly passage, by a bridge, over the Coa, and joined the main army.Argyll, who received the news of the retreat about four in the afternoon of that day, occupied Perth with Dutch and English troops by ten o'clock the next morning. They had quitted Stirling on the 29th, and that night they encamped on the snow amid the burnt remains of the village of Auchterarder. Argyll and Cadogan followed the advanced guard and entered Perth on[32] the evening of the 1st of February; but the remainder of the troops did not arrive till late at night, owing to the state of the roads and the weather. Some few of the rebels, who had got drunk and were left behind, were secured. The next day Argyll and Cadogan, with eight hundred light foot and six squadrons of dragoons, followed along the Carse of Gowrie to Dundee. Cadogan, in a letter to Marlborough, complained of the evident reluctance of Argyll to press on the rebels. When he arrived at Dundee on the 3rd, the rebel army was already gone. He and Cadogan then separated, taking different routes towards Montrose. Cadogan, whose heart was in the business, pushed on ahead, and on the 5th, at noon, reached Arbroath, where he received the news that the Pretender had embarked at Montrose and gone to France. In this manner did the descendant of a race of kings and the claimant of the Crown of Great Britain steal away and leave his unhappy followers to a sense of his perfidious and cruel desertion. His flight, no doubt, was necessary, but the manner of it was at once most humiliating and unfeeling. The consternation and wrath of the army on the discovery were indescribable. They were wholly broken up when Argyll reached Aberdeen on the 8th of February.
