This is Sir Arthur (whose valour and skill, began so well, but ended so ill)
Who beat the French, who took the Gold, that lay in the City of Lisbon.

Windham, writing in his Diary under date of the 16th September, probably sums up the thoughts of most British statesmen of the time: “At Chesterford heard report of news; said to be excellent, but without particulars. Feasted upon the hopes of what I should meet at Hockrill. Alas! quanti de spe decidi! it was the news of the convention with Junot. There never was surely such a proceeding in the history of wars or negotiations. There is no bearing the thought of it.”

A Court of Inquiry was instituted. Dalrymple and Burrard were recalled, and together with Wellesley, were examined before a board of officers, which included General David Dundas and Lord Moira, at Chelsea Hospital. The finding of the Court was non-committal “respecting the fitness of the Convention in the relative situation of the two armies,” doubtless because a unanimous “verdict” could not be arrived at, but the members definitely declared “that unquestionable zeal and firmness appear throughout to have been exhibited by Lieut.-Generals Sir Hew Dalrymple, Sir Harry Burrard, and Sir Arthur Wellesley....” In commenting on the judgment thus expressed, Sir Herbert Maxwell notes that the two senior officers were never employed again, adding, “Similar eclipse might have fallen upon Sir Arthur, but for the efforts of Castlereagh and other powerful friends, whose confidence in their General was never shaken.”

In the following January (1809) the House of Lords and the House of Commons expressed their thanks to General Wellesley for the victories of Roliça and Vimiero.

“It is your praise,” said the Speaker in the Commons, “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 characterized 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. It is, therefore, with the highest satisfaction, that, in this fresh instance, I now proceed to deliver to you the thanks of this House....”

Wellesley’s reply was made in three well-chosen sentences, without the slightest attempt at rhetoric. In the House of Lords Vimiero was spoken of as “a signal victory, honorable and glorious to the British arms.” The resolutions of the peers, which included high appreciation of the behaviour of the non-commissioned officers and privates, were conveyed to Sir Arthur by the Lord Chancellor, and acknowledged by their recipient in a short letter, the most important paragraphs of which are as follows:

“I have received the mark of distinction which the House of Lords have conferred upon me with sentiments of gratitude and respect proportionate to the high sense I entertain of the greatness of the honor which it carries with it; and I shall have great pleasure in communicating to the Officers and the troops the distinguished reward of their exemplary conduct which their Lordships have conferred upon them.

“I beg leave, at the same time, to express to their Lordships my thanks for the expressions of personal civility with which your Lordship has conveyed to me the commands of the House.”

These signs of approval must have been entirely satisfactory to Sir Arthur after the bitter criticisms of the previous months, but what he particularly valued was a handsome service of plate, worth intrinsically £1000, but sentimentally beyond price, presented to him by the brigadier and field officers who were associated with him in the victory at Vimiero. They, at any rate, had implicit faith in their General.
