Probably not the right place, but I'd like to chime in and suggest that Andrew Humphrey's stats be improved to 4-1-1, maybe even 4-2-1.
In his book on Antietam Stephen W. Sears states that Humphreys moved his division 23 miles overnight to reach the Army of the Potomac the day after Antietam and having successfully managed to bring 6,000 of his 6,600 men with him.
