The battalion was enlisted for an indefinite period, picked men from the militia companies in the various counties, for defense of the State, under orders of the Confederate army officers, and went into camp at Okolona in September, 1862. The field officers were elected September 25. Early in October they were ordered to Columbus. Gen. John Adams, commanding the Fourth District, reported January 5, 1863, Third Battalion, aggregate, 399. "They were sent to Vicksburg by order of General Pemberton November 28, 1862, and are now there in the actual service of the Confederate States. These troops never were mustered into the service of the Confederate States, but have been and still are performing guard and other duties at this post. The State troops are styled by the Governor Minute Men, have arrived at a certain degree of proficiency and will compare favorably with Confederate States troops of the same length of service." Colonel Burgin, who left Columbus in command of the battalion, was stationed at Snyder's Bluff, in command of a brigade. This battalion was the only organization of State troops listed in Gen. M.L. Smith's statement of January, 1863.
Captain Jeptha V, Harris, of the battalion, was promoted as Brigadier-General, commanding Minute Men at Columbus, September 2, 1862. M. P. Jones was his Adjutant. January 19, Gen. Ruggles, commanding at Columbus, ordered Brig.-Gen. Harris, commanding State troops, to remove his brigade, consisting of Fifth Regiment and Third Battalion, to a suitable position about one and one half miles north of this post on the Aberdeen road. Return of Fourth Brigade, Brig.-Gen. J. V. Harris, for February, 1863, Third Battalion. 246 present, 413 aggregate, stationed at Columbus.
