Hi Eric:
Most of what I know comes from the Official Records. I have been able to identify the three brigades of Loring's Division arriving by train at different times at Kinston on March 9th. I have not been able to place them on the battlefield with any specificity other than to know that they were on the line of battle between Dover Road and the railroad.
Contact me by e-mail if you need help sorting through the various Army of Tennessee command structures.
Hugh
