A force was despatched to Portugal under the command of Sir Arthur Wellesley; but no sooner had he achieved some success than he found himself superseded by Sir Harry Burrard, who in turn had to give place to Sir Hugh Dalrymple. The consequence was, that the good accomplished by one commander was quickly undone by another, and in August a Convention--known as the Convention of Cintra--was signed, and the French army was allowed to return home scot free. This raised a storm of indignation among the citizens, and the king to pacify them promised an enquiry. He little liked, however, the City's interference in the matter, and said so:--"I should have hoped"--he told the Common Council who waited upon him--"that recent occurrences would have convinced you, that I am at all times ready to institute enquiries on occasions in which the character of the country or the honor of my arms is concerned; and that the interposition of the city of London could not be necessary for inducing me to direct due enquiry to be made into a transaction which has disappointed the hopes and expectations of the nation."[675] Wellesley and his two official superiors were thereupon ordered home to give an account of their conduct, the command of the army in Portugal being left in the hands of Sir John Moore, who soon afterwards lost his life at Corunna. [Sidenote: Scandal of the Duke of York, 1809.] The Convention of Cintra and the retreat of Sir John Moore, successful as that retreat had been, although costing him his own life, discouraged the government which now was called upon to meet an attack from another quarter. Early in the spring of 1809, the Duke of York, commander-in-chief, was charged by a militia colonel named Wardle, member for Okehampton, with having allowed his mistress, Mrs. Clarke, to dispose of commissions, and having himself participated in the proceeds of this nefarious traffic. The scandal was aggravated by a public investigation before the entire House of Commons, and although the duke was eventually acquitted of personal corruption, he felt compelled to resign his post. His acquittal disgusted the Common Council, who desired to place on record their belief that it was greatly due to that "preponderating influence" of which they had formerly complained. On the other hand they voted Wardle the Freedom of the City in a gold box (6 April).[676] In the course of a few months Wardle was himself sued by a tradesman for the price of goods with which he had furnished a house for Mrs. Clarke. This put a new aspect on the charges Wardle had brought and greatly diminished the feeling against the duke, who was soon afterwards restored to office. The City, however, still upheld Wardle, and not only refused to rescind their vote of the 6th April, but placed on record an elaborate statement showing how by his means, and in the face of unexampled threats and difficulties, a system of "scandalous abuse and corruption, not only
