The theatre of war was gradually increasing, and, in 1808, Sir Arthur received orders to embark for Corunna and oppose the victorious armies of France, now assembled under chiefs whose fame resounded through the whole of Europe; for Spain had been invaded, and England sought to measure her strength in the field with that of Napoleon. The fleet was directed towards Oporto, and Sir Arthur effected his landing in Portugal in the face of the brave regiments of the great army, at the time when Junot was assuming a regal position at Lisbon: the monarchy of the house of Braganza appeared at this period like a brilliant ring, which was successively fitted on the finger of all the adventurous chiefs, despatched as a sort of disgrace to Portugal by Napoleon. General Junot compromised the army by his want of capacity and his vain pretensions, and the 21st of August was marked by the battle of Vimiera, where the attack was commenced by the French. The complete destitution of the army rendered a treaty necessary, and by the miserable capitulation, called the Convention of Cintra, it was agreed that the French should evacuate Portugal and return into France with their arms and baggage. Sir Arthur did not sign this convention, and the real author of it, Sir Hew Dalrymple, being violently attacked by the opposition, Sir Arthur quitted the army to be present at the debates, and at the trial of Sir Hew by a court-martial. The Convention of Cintra has been greatly blamed by Lord Byron in his poem of "Childe Harold." Dalrymple was deprived of his command, and he was succeeded by Sir Arthur Wellesley, who landed at Lisbon on the 22d of August, 1809. By the direction of Napoleon, the most bitter ridicule was cast upon him in the _Moniteur_; those wretched declamations against his adversaries were a weak and contemptible trait in the emperor's character, shewing a spirit of littleness in the midst of all his great qualities. The following is the article he dictated in Paris, with a mixture of folly and presumption:-- "We are very well pleased Lord Wellington should command the armies, for, with the disposition he evinces, he will meet with great catastrophes.... Sir John Moore and Lord Wellington shew no symptoms of the provident forethought which is so essential a quality in warlike operations, which leads people to do nothing but what they can maintain, and to undertake nothing but what offers a probability of success: Lord Wellington has not shewn more talent than the cabinet of St. James's. To attempt to support Spain against France, and to enter into a struggle with France upon the Continent, is to form an enterprise which will cost dear to those who have attempted it, and occasion them nothing but disasters."
