Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
Company A - Captain W. C. Blanton, Captain Ambrose M. Hayden - enrolled Johnson County, Missouri. Most of this company was transferred from Burn's 11th Regiment Missouri Infantry.
Company B - Captain John S. Phillips - mustered Little Rock, Arkansas.
Company C - Captain Amos F. Cake, Captain David A. Lilly. Many came from the 10th Regiment Missouri Infantry.
