"On Wednesday, 17 July, Colonel Hoke, with seven companies of the regiment, left the 'Camp of Instruction' at Garysburg, N C, in freight cars for Richmond, Va. Companies C, D and H, were for the time being necessarily left behind on account of the prevalence of measles among the men."

Notes

On 8 May, 1861, ten regiments of North Carolina State Troops, numbering 1st through 10th, were organised to serve "during the present war" under the Act of the General Assembly of North Carolina. Two days later, thirteen regiments of volunteers for 12 months' service were authorised, numbering 1st through 8th and 10th through 14th. Thereafter, the original ten regiments of state troops kept their numbering, but the volunteers were renumbered and all units were subsequently referred to as North Carolina Troops. The 13th North Carolina Infantry was one of the thirteen regiments of 12 months' volunteers and was redesignated the 23rd North Carolina Troops in November 1861.

Seven companies of the 13th North Carolina Infantry, under the command of Colonel J F Hoke, arrived at Manassas Junction during Sunday night after being sidetracked at Louisa Court House to allow trains of wounded to pass and were therefore not present on 21 July, 1861. The regiment spent the night on the wooden floors of the box cars and went into Camp at 'Camp Wigfall'. Companies C, D and H had a prevalence of measles and remained at 'Camp of Instruction', Garysburg, under the command of Major D H Christie, rejoining the regiment at 'Camp Wigfall', Manassas, August, 1861.

On 25 July 1861, the Army of the Potomac was reorganised and the 13th North Carolina Infantry was assigned to the Sixth Brigade, First Corps, Army of the Potomac, under the command of Colonel J A Early.
