Lord Castlereagh began his career in the Irish Parliament, by a motion for a committee to inquire into the representation of the people, with the ulterior object of a reform in Parliament. He made a good speech, and had a majority in the House, which he certainly did not expect, and I am sure did not wish for. He was unequal and unwilling to push that point to further trial: the matter cooled in a few days; and after the next division, was deserted entirely. Mr. Stewart, however, after that speech, was considered as a very clever young man, and in all points well taught and tutored by his father, whose marriage with the Marquess of Camden’s sister was the remote cause of all his future successes:—how sadly terminated!

At the period to which I allude, I feel confident nobody could have predicted that one of those young gentlemen would become the most celebrated general of his era, and the other the most unfortunate minister of Europe. However, it is observable, that to the personal intimacy and reciprocal friendship of those two individuals, they mutually owed the extent of their respective elevation and celebrity:—Sir Arthur Wellesley never would have had the chief command in Spain but for the ministerial aid of Lord Castlereagh; and Lord Castlereagh never could have stood his ground as a minister, but for Lord Wellington’s successes.

At my house the evening passed amidst that glow of well-bred, witty, and cordial vinous conviviality, which was, I believe, peculiar to high society in Ireland.

From that night I became somewhat intimate with Captain Wellesley and Mr. Stewart; and perceived certain amiable qualities in both. Change of times, or the intoxication of prosperity, certainly tends either to diminish or increase some natural traits in every man’s character, or to neutralise qualities which had previously been prominent. Indeed, if Lord Wellington had continued until now the same frank, plain, open-hearted man, he certainly must have been better proof against those causes which usually excite a metamorphosis of human character than any one who ever preceded him. Still, if possible, he would have been a greater man; at least, he would have better drawn the distinction between a warrior and a hero—terms not altogether synonymous.

Many years subsequently to the dinner-party I have mentioned, after Sir Arthur had returned from India, I one day met Lord Castlereagh in the Strand, and a gentleman with him. His lordship stopped me, whereat I was rather surprised, as we had not met for some time: he spoke very kindly, smiled, and asked if I had forgotten my old friend? It was Sir Arthur Wellesley whom I discovered in his companion; but looking so sallow and wan, and with every mark of what is called a worn-out man, that I was truly concerned at his appearance.—But he soon recovered his health and looks, and went as the Duke of Richmond’s secretary to Ireland; where he was in all material traits still Sir Arthur Wellesley—but it was Sir Arthur Wellesley judiciously improved. He had not forgotten his friends, nor did he forget himself. He told me that he had accepted the office of secretary only on the terms that it should not impede or interfere with his military pursuits; and what he said proved true, for he was soon sent, as second in command of the troops, with Lord Cathcart to Copenhagen, to break through the law of nations, and execute upon a Christian state and ancient ally the most distinguished piece of treachery that history records.

On Sir Arthur’s return he recommenced his duty of secretary; and during his residence in Ireland, in that capacity, I did not hear one complaint against any part of his conduct either as a public or private man. He was afterward appointed to command in Spain: an appointment which was, I then thought, expected by Sir John Doyle. I do not mean to infer the least disparagement to either the military or diplomatic talents of Sir John; but his politics, or at least those of his friends, were opposite, and he might have pursued a very different course to decide (for the time being) the fate of Europe.

A few days before Sir Arthur’s departure for Spain, I requested him and Lord Manners to spend a day with me, which they did. The company was not very large, but some of Sir Arthur’s military friends were of the party:—the late Sir Charles Asgill, the present General Meyrick, &c. &c. I never saw him more cheerful or happy. The bombardment of Copenhagen being by chance stated as a topic of remark, I did not join in its praise; but, on the other hand, muttered that I never did nor should approve of it.

“Damn it, Barrington!” said Sir Arthur, “why? what do you mean to say?”—“I say, Sir Arthur,” replied I, “that it was the very best devised, the very best executed, and the most just and necessary ‘robbery and murder’ now on record!” He laughed, and we soon adjourned to the drawing-rooms, where Lady Barrington had a ball and supper as a finish for the departing hero.

In 1815, having been shut up in Paris during the siege, I went out to Neuilly to pay a visit to the duke before our troops got into the city.—I had not seen him since the day above-mentioned; and he had intermediately much changed in his appearance, though seeming just as friendly.
