If you decide to go ahead with the list, may I make a contribution? June 8, 1864, engagement between Boone's Artillery (2nd La. Lt. Arty) and US gunboats Chillicothe, Neosho, and Fort Hindman, at Simmesport, La. "One of the 30 pounder Parrott guns recently captured from a gun-boat on Red River burst at the breech at the third discharge, expanding the wrought-iron band or re-enforce and splitting the breech of the gun about 30 inches, slightly wounding one man." "It seemed to have been caused by the re-enforce not fitting the gun tightly, as the latter opened about one-quarter of an inch without damaging the former." ORA, Vol. 34, pt. 1, pp. 988-989. The gun probably came from the US tinclad Covington.
