My muster as colonel dates back to November 10, 1862, several months earlier than any other of which I am aware, among colored regiments, except that of Colonel Stafford (First Louisiana Native Guards), September 27, 1862.

Colonel Williams, of the "First Kansas Colored," was mustered as lieutenant-colonel on January 13, 1863; as colonel, March 8, 1863.

These dates I have (with the other facts relating to the regiment) from Colonel R.J.Hinton, the first officer detailed to recruit it.
To sum up the above facts: my late regiment had unquestioned priority in muster over all but the Louisiana regiments.

It had priority over those in the actual organization and term of service of one company.

On the other hand, the Kansas regiment had the priority in average date of enlistment, according to the muster-rolls.
The first detachment of the Second South Carolina Volunteers (Colonel Montgomery) went into camp at Port Royal Island, February 23, 1863, numbering one hundred and twenty men.
