A fatal duel took place at Washington, between two members of the House of Representatives, Mr. Cilley of Maine, and Mr. Graves of Kentucky. Mr. Cilley had spoken disrespectfully of Colonel Webb, editor of the New York Courier; whereupon Mr. Webb sent him a challenge by Mr. Graves. Mr. Cilley said he would not fight such a blackguard as Webb, but was ready to accept a challenge from Mr. Graves. The following is an account of the arrangements for the meeting, drawn up by Mr. Cilley’s second:—“Mr. Cilley proposes to meet Mr. Graves, at such place as may be agreed upon between us, to-morrow at twelve. The weapons to be used on the occasion shall be rifles; the parties, placed side to side at eighty yards’ distance from each other, to hold the rifles at arm’s-length, downwards; the rifles to be cocked, and triggers set; the words to be, ‘Gentlemen, are you ready?’ After which, neither answering ‘No,’ the words shall be in regular succession, ‘Fire—one, two, three, four.’ Neither party shall fire before the word ‘fire,’ nor after the word ‘four.’ The position of the parties, at the ends of the line, to be determined by lot. The second of the party losing the position, shall have the giving of the word. The dress to be ordinary winter clothing, and subject to the examination of both parties. Each party may have on the ground, besides his second, a surgeon and two other friends. The seconds, for the execution of their respective trusts, are allowed to have a pair of pistols each on the ground; but no other person shall have any weapon. The rifles to be loaded in the presence of the seconds.” Three shots were exchanged without harm: at the fourth, Mr. Cilley was shot through the heart. Cilley’s funeral was attended by six hundred persons, in one hundred and twenty-five carriages. The seconds afterwards published a statement, declaring that the duel was “regulated by magnanimous principles, and the laws of humanity.” BETWEEN SIR JOHN MILLEY DOYLE AND DR. LOVELL. March 1838.
