The Orbats at Antietam
While doing some research on Antietam I've found that the commonly
accepted orbats seem wrong, based on the orbats implemented a week
later (Confederate, see Harsh) or a week earlier (Union, comfirmed
from McClellans Report to the Secretary of War).
Thus the organisations of the two armies at Antietam seem to be:
Right Wing (Longstreet)
DR Jones' Division
Walker's Division (at the beginning, later attached to Jackson)
Walton's Arty Bn
Robertson's Cavalry Brigade
Centre Wing (DH Hill)
DH Hill's Division
Longstreet's Division (RH Anderson)
Cutt's Arty Bn
HP Jones' Arty Bn
Left Wing (Jackson)
Hood's Division (attached from Longstreet)
McLaws' Division (attached from DH Hill)
SD Lee's Arty Bn
Stuart with Fitz Lee's Brigade (the corps brigade) and Hampton's (DH
Hill's Corps brigade, attached)
AP Hill is still en route
Right Wing (Burnside): 9th Corps and 5th Corps (only Sykes' Division
initially, Morell's arrives later), Artillery Reserve is attached.
Centre Wing (Franklin): 6th Corps (arrives very late in the day) and
4th Corps (only one division, absent masking Harper's Ferry)
Left Wing (Sumner): 1st, 2nd and 12th Corps, and Cavalry Division
NB: The Wing structure *is* still in use at Antietam.
- Jackson has some real problems as a tactical commander, and he keeps making
the same mistakes, which suggests that he wasn't very introspective about
developing those skills. None of his battles really display a flair for tactics,
even Chancellorsville, where his choices of divisions in line instead of
column greatly complicated his own attack.
That said, he was quite effective at what we today would call the

the only Federal commander to beat him, and do so pretty soundly,
was James Shields. (Even there, actual field commander was Nathan
Kimball.) That said, Jackson had, after Shields, mediocre Federal
commanders to contend with....
