"When Castlereagh was at Chatillon with the ambassadors of the allied powers, after some successes of mine, and when I had, in a manner, invested the town, _he was greatly alarmed lest I might seize him_ and make him _prisoner_. Not being accredited as an ambassador, nor invested with any diplomatic character to France, I might have taken him as an enemy. He went to Caulincourt, to whom he mentioned that _he laboured under considerable apprehensions that I should cause violent hands to be laid upon him_, as he acknowledged I had a right to do. It was impossible for him to get away without falling in with my troops. Caulincourt replied, that as far as his opinion went, he would say that I should not meddle with him; but that he could not answer for what I might do. Immediately after, he (Caulincourt) wrote to me what Castlereagh had said, and his answer. I signified to him in reply, that he was to tell Castlereagh to make his mind easy, and stay where he was: that I would consider him as an ambassador. At Chatillon, (continued Bonaparte) when speaking about the liberty enjoyed in England, Castlereagh observed, in a contemptuous manner, that it was not the thing most to be esteemed in England; that it was an USAGE they were obliged to put up with; but that it had become an abuse, and would not answer for other countries." It will thus be seen that GRATITUDE, at least, ought to have prompted different conduct in Lord Castlereagh towards Napoleon; instead of which, the charges brought against Sir Hudson Lowe by Mr. O'Meara were not only deemed unworthy of inquiry, but his lordship actually dismissed the accuser from the British service. Thus a deserving and generous-minded officer was ruined, without even a hearing, for merely attempting to do an act of justice to the exiled Emperor of France! The charges against Sir Hudson Lowe, however, remained the same, and this summary mode of revenge inflicted on Mr. O'Meara was not at all calculated to acquit Lord Castlereagh from sharing in the accusation of wantonly oppressing Napoleon. Could any thing tend more to criminate his lordship than the sudden punishment of the accuser, while in the act of preferring his complaint? Grant that Mr. O'Meara had misconducted himself, and that he had thus given his employer a right to dismiss him, surely he ought not, in common honesty, to have done so till he had first given him every opportunity of making good his charges. His lordship's readiness to stigmatize, and even silence him, in this manner, wore any appearance but that of an honourable anxiety to meet and to defy his adversary. We cannot devote space sufficient to bring forward the charges of Mr. O'Meara; but the inquirer will find himself amply repaid for his trouble by their perusal. As Sir Hudson Lowe can only be looked upon as a cowardly ruffian, who scrupled not to _execute_
