John George Walker (CSA):
I was just looking through the Antietam order of battle and came across him (I admit I'm not very familar with his accomplishments)
"In November 1862, Walker was promoted to major general and transferred to the Trans-Mississippi Department, where he was given command of 12 Texas regiments, numbering 12,000 men, training at Camp Nelson in Arkansas. Walker formed the regiments into a Division, which earned the nickname "Walker's Greyhounds" for their ability to move quickly over many miles on foot. From November 1862 until the end of the war, the Greyhounds were formed exclusively of soldiers from Texas, and did not leave the Trans-Mississippi Department."
It sounds like he might be a good candidate for "Fast_Move" or "Training_Officer."
