Thanks, George. As I "read up" a bit on Gen. Wright, I realized that he was the same person involved for decades in the effort to preserve the Confederate record in conjunction with the US War Dept, part of the OR (Army) and what we know as the CSR files of NARA, plus several published works of his own or in support of others, compiling reference info and the like. I'm satisfied for now as to his identity, but do need to gain a better appreciation of how Atlanta prepared to meet the coming of Sherman from, say, Mar-Apr 64 when he took over as commander of the Atlanta "post." His involvement with Lieut (or "Capt") Bain, Chief Sig Officer of the AT, raises questions in my mind about the relationship between the field Army of Tenn and the departmental arrangements that embraced Georgia and Atlanta, and how Wright was able to call upon AT resources (and staff specialists) for support. (It suggests the relationship between the ANV and Milligan's "extra-legal" signal unit in Petersburg in 1864-65 which is still a puzzle.) Overlooking the existence and role of staff, not to mention the members at any given time, seems to be common among modern historians, who evidently want to concentrate on the Great Man himself and see no need to bother with the research (or diminish the glory of their hero, not appreciating the role of staff). Because the Confederate Army Signal Corps was not a unit, with State of Central Govt, numbered, identity (and organizational flag), but "extra duty" specialists serving on detail under a cadre of officers, they seldom show up in orders of battle or military history. Sometimes the activity of these detailed privates reflects the activity of his officer and unit not found elsewhere; otherwise the identity of the officer helps to account for his men and what they were doing. Special Orders, personal papers, the individual's CSR, and the like are grist for the mill. Which grinds "exceeding slow." A number of "signal officers" were not officers; a number of "signal officers" did not hold Signal Corps commissions or legal appointments. So it goes. Thanks again for your help.
