Mr. Caudle,
Not long ago I was conducting some research on Bledsoe's Battery and came across the same confusion. I read the refrences you list as well as several refrences to "Old Sacramento" in Confederate Veteran Magazine, all of which led me to believe there were indeed two cannon with the same name. CV vol. XXVIII p. 237 has the cannon with Bledsoes Battery at Port Hudson and goes on to say it was at Raymond, Jackson and Chickamauga. CV vol. XXVIII, p. 52, states the gun which was in Bledsoes Battery (and made of silver)was captured at the Battle of Sacramento in Old Mexico (February 28, 1847, along the El Paso Road north of Chihuahua) and was in all of the battles "from Missionary Ridge to the sea." The author claims he saw the cannon last in Mobile.In CV XXVIII p. 292, William Mattson claims the gun was exchanged when General Price crossed the river at Memphis (April 1862). W.A. Everman on page 140 claims "Sacramento" was in every battle with the battery through Vicksburg and then believes it was transferred to Forrest's command. In volume VII p. 462 Joseph Wilson claims the gun was a 9 pounder bored out and converted to a 12 pound howitzer, and was cast by the Mexicans with a quanity of silver in it. There is a trivia question concerning the Kansas cannon at www.kancoll.org/articles/kstrivia/answers.htm

In the November 4th, 1894 edition of the St. Louis Post Dispatch, Hunt P. Wilson details his experiences as an artilleryman in Guibor’s Battery during the war. Of note in this article is Wilson’s description of a “six-pound brass gun which had a large proportion of silver in its composition, a piece of field ordnance captured from Santa Anna during the Mexican War”. Wilson goes on to refer to this piece as “Old Sacramento.” A careful study of this account draws some doubt as to its validity. First there is no Hunt P. Wilson on the muster rolls of Guibor’s Battery, though his name does appear on the rolls of Landis’s Missouri Battery a unit that often fought near Guibor’s. Secondly, other than Wilson’s article, there are no other accounts that “Old Sacramento” saw service with Guibor’s Battery. On the other hand there are numerous references to “Old Sacramento” in the accounts and remembrances of members of Captain Hiram Bledsoe’s Missouri Battery, another unit that often served near both Guibor’s and Landis’s batteries. It is quite possible that Hunt Wilson embellished his story to the St. Louis Post confusing or purposely distorting facts that occurred over thirty-two years before.

An intresting related item; In ZCV volume XI page 424, Gibson Garwood of Bledsoe's Battery mentions a cannon in the unit known as the "Black B*tch".

Maybe I just added more confusion, but I thought I would share it.
