Witness: It was then nearly 7 o’clock. On arriving at the Common, I saw the entire party collected near to the Windmill, and the post-chaise proceeding in that direction. Having dismounted, and left the horse in the care of a countryman, I proceeded to where the chaises were standing, and then I saw the defendants walking away, from them, some yards down, to a hollow part of the ground, each party apparently making arrangements about the duel. They then stopped, and as I approached Col. Parquin, seeing two letters in one hand, and the two swords produced, in the other, I took them from him. At that time, the pistols produced, in a case, were lying on the ground, near to another brace, which were wrapped up in paper. Some conversation passed between Count D’Orsay and Col. Parquin, which appeared to be whether the combat was to be fought with pistols or with swords, and the Count asked me what I wanted; my authority for interfering; and who it was that gave me information of the circumstance. At that moment, Inspector Partridge, accompanied by Sergt. Otway and other constables, came up, and, on Col. Ratcliffe taking the pistols from the case, he was taken into custody. I instantly went to him, and, shewing him my staff, told him I was an officer, and that I was, in duty, bound to take him into custody, for attempting to commit a breach of the peace. Count D’Orsay requested to be told who it was who had given the information, and, on being refused, the entire party were quietly conveyed to the station house. Mr. Jardine: Have you since ascertained that the pistols contained powder and balls? Witness: Yes, Sir; there are balls in them, and caps upon them. Colonel Ratcliffe declared there was no powder in the pistols, which belonged to him, as could be seen; for it had been arranged that the duel was to be fought with swords. Mr. Jardine inquired if any of the defendants, who were foreigners, and not sufficiently conversant with the English language, would wish to hear the evidence read over to them in French? Le Comte Leon replied in French, that he could not sufficiently understand the evidence that had been given, but he was quite satisfied that all the proceedings were perfectly legal and correct. Prince Louis said, he was prepared, if required, to enter into an explanation of the circumstances which gave rise to the offence with which he was charged. Mr. Jardine did not wish to hear any statement on either side, as his duty was only to prevent a breach of the peace, and he hoped the defendants were prepared with the sureties he would require, to prevent further inconvenience. Count D’Orsay said, he had come prepared with bail, which he thought there could be no objection to.
