Lawyer; born in
Nottingham, N. H., July 2, 1802; graduated at Bowdoin College in 1825; elected to Congress as a Democrat in 1837, and served until Feb. 24, 1838, when he was fatally wounded in a duel with
William J. Graves, a Representative from
Kentucky.
The trouble arose from an address in the House of Representatives by
Mr. Cilley, in which he denounced a charge of immorality made against some unmarried Representatives in an article published in the New York
Courier and Enquirer under the signature of “A spy in
Washington.”
The result of this criticism was the challenge to a duel by
Mr. Graves.
The weapons used were rifles; the place,
Bladensburg, Md.; and on the third shot
Mr. Cilley fell, with a ball through his body.
When the affair became known in Congress, a committee of seven was appointed, and after a thorough investigation, reported that
Mr. Graves should be censured by the
House for his conduct.
