The newspaper article notes that the Negro troops were raised in this county, this referring to the previous paragraph which noted Col. T. D. Merricks 10 Arkansas Regiment which was raised at Springfield, Lewisburg and Quitman.
It would appear the reference to these Negro troops forming Company C of the 22nd Arkansas to be in error as this was a Western Arkansas unit. Could possibly mean Co. C, 31st Regiment, Arkansas Infantry which was raised in Conway county.
However, as I’ve previously remarked to you, I would doubt a Negro company would be raised for Confederate service in the 1861/2 time frame which this appears to be.
