He was specifically asked for by Governor Brown of Georgia to command a division of Georgia home troops. His troops may have been under the command of the AoT but I don't know if they were actually attached as a part of the main army.

1/8/65--12 m Charleston, Hardee to Pres Davis-Your cipher telegram of the 7th received today.
I am holding the line of RR from the Savannah River to this place. The principal force on this line is at Pocataligo, under Maj-Gen McLaws, who when compelled to retire will take up the line of the Combahee, which I am actively engaged in fortifying.
Maj-Gen Wright's Div is stationed in the 4th Sub-District principally to protect the approaches from John's Island to the lower Combahee, inclusive.
Gen Taliaferro's Div is distributed in the 2nd & 3rd Sub-Districts, principally on James & Sullivan's Islands & in Christ Church Parish.
Conner's Bgde when it arrives will be stationed near Charleston whence it can reinforce the 2nd, 3rd, or 4th Sub-Districts.
