@jepridgen Found info about their armament. It's a great newspaper article that shows a report of Henry C. Wayne, Adjutant and Inspector Gen. of GA, for the year October 1862- October 1863 written to Governor Brown.
"… No sooner had these (2) Regiments been organized, then, under your orders, on calls for aid from Generals Beauregard and Mercer, they were placed in the field at Savannah, to meet a threatened attack of the enemy. ….. the 2nd Regt was attached to the Brigade of Confederate troops under the command of Gen. W. H. T. Walker and the 1st Regt. to the Brigade of Confederate troops under the command of Gen. Taliaferro.
The movements of the enemy indicating Charleston as the probable point of attack, Gen. Beauregard desired the presence of two regiments at that city and your permission for them to go having been given, and communicated to the regiments, thro' Gen Mercer, both of them, though held to service by agreement only within the territorial limits of GA, responded with cheers to the appeal of Gen. Beauregard, and repaired to Charleston under the command of the gallant Georgian, Gen W. H. T. Walker, whose Brigade had been also called to the defense of Carolina."
He describes how they were well receive at Charleston. Very interesting that they were able to leave GA.
He mentions that he has a force of 1,800 men, this was Oct. 1862-3. As
@JSylvester said, the number was lower by the spring of 1864.
Also, mention of the Militia and he voices some very definite opinions.
"In August last the Conf. Gov. returned to the State 1500 Austrian Rifles to replace as many of the State's Enfield guns taken by Conf. officers on their arrival at ports in the Confederacy. One thousand of these rifles were turned over to the 2nd Regt, GA State Line, whose old muskets were turned over to the Home Guard, reporting at Resaca under your order of Sept. 5th, and one hundred were issued to a company in the 1st Regt that had arms of an old and inferior character."
Notice he says 100 rifles to "a company" of the 1st. I guess the other companies did not need them? Giving 1,000 to the 2nd makes me think they didn't have many to start with.
It's a long article but very interesting.
