March 21, 1864, W.N. Pendleton, Brigadier General Artillery, provided a report of his inspection of the various artillery battalions belonging to the Army of Tennessee. Attachment No. 4 to that inspection report was the he Statistical report of the battalion of artillery, of Hood’s Corps, commanded by Capt Robert Cobb. Captain Cobb’s report has and interesting foot note that referrers to the disposition of Hart’s Arkansas Battery.

a. The following batteries have been consolidated in ton, with such of their equipment's as was required to make the battery effective: Byrne’s [Mississippi] Battery at Corinth, May 1862: Graves [Mississippi] battery, at Murfreesborough, November, 1862: fragments of Green’s [Kentucky] battery, Hart’s [Arkansas] battery, and Water’ [Alabama] battery in January 1864.

It is now my belief that it is this report that some have mistaken for the ultimate disposition of Providence’s/Humphreys/Rivers Arkansas Battery. I believe that the remnant of Hart’s Battery referred to above are the men of Hart’s second organization which was captured at Arkansas Post in January 1863. The surviving remnants of the battery were released and exchanged at City Point Virginia in April and May 1863 and eventually, along with the remnants of the 19th and 24th Arkansas Infantry Regiments, were sent to the Army of the Tennessee while that organization was at Tullahoma, Tennessee.
