Lee is an interesting character. He entered service as Captin of Co. "D", Villepigue's 36th Georgia Regiment, resigned.
Lee was then elected Colonel of the 38th Georgia Regiment, and resigned again, citing poor health. The second resignation was effective July 15, 1862. He received an appointment from the War Department as a Captain and A.A.G. Nearly all of the information I located on him came from his file as a staff officer.
Here is General Bragg's assessment of Lee, taken from a letter to General Johnston, dated March 2, 1863:
The case of "Col. G. W. Lee, commanding at Atlanta," is a very prominent one. A man without education or character--you will observe he never signs his own name--who was so well known that his Governor would not accept a company under his command. The War Department accepted it, and sent him to me at Pensacola, in the spring of 1861. When under arrest on serious charges, he resigned and left, and is accused of stealing the clothing money of his men, then in his hands. By misrepresentation and downright falsehood, and by evading and misconstruing orders, he has raised a force of nearly 500 men at Atlanta, more than half conscripts, "home guards." I am compelled to leave this man in command of 2,000 sick men of my army, and intrust their lives, funds, and safety to him. Of course, I cannot keep an old soldier of rank and character under him, and to deprive so large a number of my army of proper control is destructive of discipline and efficiency. Lee has no appointment but captain and provost-marshal--an office unknown to the law. The state of affairs at Atlanta is disgraceful: prisoners confined for months, even without charges; employés by the dozen, able-bodied and without occupation; and expenditures most lavish. If not sustained at :Richmond, I will remove my hospitals this way and give up the place.
Very truly, yours, BRAXTON BRAGG.
