Sir Arthur Wellesley landed at the mouth of the river Mondego in Portugal on the 3rd of August. Here he received intimation that re-inforcements under Sir John Moore were about to be sent. Moore was his superior officer, and there was also Sir Hew Dalrymple and Sir Harry Burrard on their way, the former of whom would take the chief, and the latter, the second command of the army. There was but little time for Sir Arthur to strike the decisive blow, and although he was not the man to force a battle for the sake of fame, he could not but feel anxious for distinction in this new sphere before all opportunity should be cut off, by the arrival of his superiors in command. Fortune in this was on his side; and he had not been many days in Portugal before he was enabled to defeat the French at the pass of Roliça, and, on the 21st of August, to gain the battle of Vimeiro.

While this battle was at its height, Sir Harry Burrard arrived, but would not interfere with Sir Arthur's dispositions. The French were soon after beaten on the left, and Sir Arthur then urged on Sir Harry the advance of our right wing upon Torres Vedras, while our left would pursue the enemy: his object being to cut off Junot's retreat on Lisbon. No man now doubts that this was counsel wise as well as bold; but Sir Harry Burrard declined to take it, and the golden opportunity was lost. Sir Arthur, who carried military obedience almost to the extent of a chivalrous sentiment, submitted to the orders, though he did not acquiesce in the judgment of his superior officer; but he could not help saying to one of his officers who stood by, "well, then, we have nothing to do but to go and shoot red-legged partridges!" the common game of that part of Portugal.

Sir Arthur Wellesley's subsequent conduct to Sir Harry Burrard was highly honourable. He declared voluntarily before the Court of Inquiry that, though he still differed in opinion with Sir Harry as to the not advancing after the battle of Vimeiro, his opinion was, that Sir H. Burrard "had decided upon fair military grounds, in the manner which appeared to him to be the most conducive to the interests of the country;" and his belief, "that Sir Harry had no motive for his decision which could be supposed personal to him, or which as an officer he could not avow."

The untoward convention of Cintra, which followed the victory of Vimeiro, was received in England with one universal cry of indignation. Sir Arthur Wellesley was no farther implicated in it than that he signed it as one of the generals, although disapproving of it from the first. Pending the inquiry, instituted in England on the convention, he returned thither, and his evidence was satisfactory alike to the court and to the public.

On the 27th January, 1809, Sir Arthur received the thanks of parliament for the battle of Vimeiro. The speaker, in delivering the thanks of the House of Commons, said:—

"Amidst the contending opinions which have prevailed upon other questions, the public voice has been loud and general in admiration of your splendid achievements. It is your praise to have inspired your troops with unshaken confidence and unbounded ardour—to have commanded, not the obedience alone, but the hearts and affections of your companions in arms; and having planned your operations with the skill and promptitude which have so eminently characterised all your former exertions, you have again led the armies of your country to battle, with the same deliberate valour, and triumphant success which have long since rendered your name illustrious in the remotest parts of this empire. Military glory has ever been dear to this nation; and great military exploits, in the field or upon the ocean, have their sure reward in royal favour, and the gratitude of parliament."

Sir Arthur, in his reply, observed:—

"No man can value more highly than I do the honourable distinction which has been conferred upon me—a distinction which it is in the power of the representatives of a free people alone to bestow, and which it is the peculiar advantage of the officers and soldiers in the service of his majesty to have held out to them as the object of their ambition, and to receive as the reward of their services."

The opening allusion of the speaker to "contending opinions on other matters," was intended to mark the sense of the house that Sir Arthur Wellesley, at least, was free from blame as regarded recent transactions in the Peninsula. That the government thought so also, and had at last learned to appreciate the value of an officer whom they had so recently trammelled, was evidenced by the appointment of Sir Arthur, on the 2nd of April, to the command of the army in Portugal.

Towards the close of the previous year, complaint had been made, in the House of Commons, of Sir Arthur holding the office of secretary for Ireland while in the Peninsula. On the 14th of April, he resigned that office, and on the 22nd, he arrived at Lisbon and assumed the command of an army, disproportioned, indeed, to the service expected of it, and still more to that which they afterwards achieved, but strong in its confidence in a general who had never made a false step, or suffered a defeat.
