GDG- Re: ? and ?? /Colonel/ DeTrobriand and /Colonel/ Burling

[Alan D. Brunelle]

OK, I'll bite:

Anybody have any information and/or opinions as to why Major General Dan 
Sickles chose to leave two brigades that were led by /Colonels/ without 
any oversight of either of his two divisional commanders (Birney & 
Humphreys) back in Emmitsburg on July 1, 1863 while he took the 
remaining 4 brigades (commanded by Brig. Generals) along with his two 
divisional commanders up to Gettysburg?
