We ourselves were present at a remarkable trial for duelling, about eighteen or twenty years ago, at the Old Bailey, before the late excellent and very learned Baron Bayley, on which occasion he also laid down the rule of law respecting duelling, with uncompromising firmness and straightforwardness. This was the case of Captain Helsham, who had shot Lieutenant Crowther in a duel, at Boulogne. There were rumours of foul play having been practised; and a clergyman, the brother of the deceased, made strenuous and persevering efforts to bring Captain Helsham to trial. The latter continued, for some time after the duel, in France, though anxious to return to England; and after (as we have heard) taking the opinion of a well-known counsel at the criminal bar--who advised him that he could not be tried in this country for a duel fought in a foreign country not under the British crown--he came to England, where he was instantly arrested, under Stat. 9 Geo. IV. c. 31, § 7, which had been passed two or three years previously--viz., in 1828--and must have altogether escaped the notice of the counsel in question. That act authorises the trial, in England, of any British subject charged with having committed any murder or manslaughter abroad, whether within or without the British dominions, as if such crimes had been committed in England. Captain Helsham was admitted to bail to meet the charge, and, having duly surrendered, took his place at the bar of the Old Bailey, at nine o'clock on a Saturday morning.
