Hindman to Col Nelson cmdg. Fort Hindman
consolidate Hart's and Brown's artillery companies ordered to Devalls Bluff by Rust

I believe that this is found in the Alexander papers in the Hindman letters Correspondents between Him and Nelson. This is prior to either of these two commands recieveing their guns and I believe that they were ordered to Ford Hindman at Deval's Bluff to help man the naval Artillery taken off of the CSS Ponchartrain and placed it that Fort.

As we know that Hart's Battery was being reorganized at this time and did not reach their full compliment of presonel or field artillery until they were sent to Pine Bluff.
