While researching some weaponry of the Civil War I came across a reference to a battery of Requa guns used by the Army of the Cumberland at Chickamauga. Does anyone have any info on this? Were the guns in fact used at Chickamauga, and which unit used them? Requa guns wwere used in the Dept. of the Gulf, at Battery Wagner, and by Butler's Army of the James at Petersburg, but I was not aware that any were used anywhere else.

Thanks
