In consequence of the Earl of Cardigan having ascertained that certain letters published recently in the _Morning Chronicle_, reflecting, as his lordship supposed, on his character as an officer and a gentleman, were written by Lieut. Tuckett, late of the same regiment (11th Hussars), the noble lord sent him, through Captain Douglas, of the 11th, a challenge, which was at once accepted, and Capt. Wainwright (half-pay) was the friend selected by Mr. Tuckett to arrange the preliminaries. An apology was demanded by the noble lord, to which the reply was, that if he would deny the allegations contained in the letters referred to, it should be given. Lord Cardigan declared that certain portions of those letters were true, but that the greater part were calumnies. On this, the apology was refused, and a meeting was the consequence. It took place on the afternoon of the 12th Sep., on Wimbledon Common. The first shot was ineffectual, on both sides; but, on the second fire, Mr. Tuckett received his adversary’s ball in the back part of the lower ribs, which traversed round to the spine. The ball was extracted, and Mr. Tuckett, after a time, recovered. Subsequently, warrants were issued, and Lord Cardigan and his second were brought before the Bench of Surrey Magistrates, at Wandsworth; and after several examinations, Lord Cardigan was committed for trial on the charge of “Shooting at Capt. H. Tuckett with a pistol, with intent to murder, or do him some bodily harm”; and his second, for aiding and abetting him. The charge was laid under “An Act to amend the Laws relating to Offences against the Person” (1 Vic., c. 85, s. 3), which makes the offence set forth in the charge, a felony, punishable, at the discretion of the Court, with transportation beyond the seas, for the term of his, or her, natural life, or for any term not less than fifteen years, or to be imprisoned for any term not exceeding three years. He was tried in the House of Lords, on 16 Feb., 1841, by his peers, and the case against him broke down through a technicality. His counsel, Sir William Follett, pointed out that the prosecution had failed in proving a material part of their case, inasmuch as no evidence had been given that Captain Harvey Garnett Phipps Tuckett was the person alleged to have been on Wimbledon Common on the 12th September last, and whose card only bore the name of Captain Harvey Tuckett. The peers present returned a verdict of “Not guilty,” with the exception of the Duke of Cleveland, who added “Not guilty, legally.”
