MEMORANDUM. “Having given the Duke of Wellington the usual satisfaction for the affront he conceived himself to have received from me, through my public letter of Monday last, and having thus placed myself in a different situation from that in which I stood when his grace communicated with me, through Sir Henry Hardinge and Lord Falmouth, on the subject of that letter, before the meeting took place, I do not now hesitate to declare, of my own accord, that, in apology, I regret having individually published an opinion which the noble duke states, in his memorandum of yesterday, to have charged him with disgraceful and criminal motives in a certain transaction which took place nearly a year ago. I also declare that I shall cause this expression of regret to be inserted in the Standard newspaper, as the same channel through which the letter in question was given to the public.” * * * * * A copy of the preceding correspondence having been sent by Sir Henry Hardinge to the evening papers of the same day, the following memorandum was published by Lord Falmouth on Monday the 22nd:— * * * * * “Lord Falmouth first became concerned in the affair between the Duke of Wellington and Lord Winchilsea shortly before he met Sir Henry Hardinge on the subject, on the evening of Thursday, the 19th. Until that time, Lord Falmouth knew nothing whatever either of the previous correspondence, or of the publication which had led to it, beyond having seen the letter in the Standard newspaper. It may seem material to state, that when Sir Henry called upon Lord Falmouth, at twelve o’clock at night, with the proposal to omit the words affixed to No. 6 in parenthesis, it was after Lord Winchilsea’s answer, No. 7, had been shown to the Duke of Wellington. This point is not quite clear in the publication of Saturday. Immediately after Lord Winchilsea had received his grace’s fire, and had fired in the air, Lord Falmouth was the first to propose satisfactory reparation for Lord Winchilsea’s publication of his opinion in the Standard newspaper. Lord Falmouth distinctly declared on the ground, that it never was a question with him whether that publication was wrong, but merely whether Lord Winchilsea was in a situation honourably to subscribe to the terms proposed, after he (Lord Falmouth) was requested to undertake the business. Before the parties took their ground. Lord Falmouth delivered a sealed letter, which he had received from Lord Winchilsea on Friday night, to Sir Henry Hardinge, who returned it after the affair had been settled.” BETWEEN CAPT. HELSHAM AND LIEUT. CROWTHER. April 1, 1829.
