Thanks for this additional information on Silas Headrick. He is the Silas Headrick from Dent County. He initially served as 1st Lt of a company in the 1st Infantry Regiment (Wingo's) of the 7th Division (McBride's) of the Missouri State Guard. William O Coleman was a Captain and the adjutant of that Regiment. After the initial 6 month service, Silas joined Coleman's Cavalry (at that time the 4th Cavalry Regiment of the 7th Division MSG). He was captured at West Plains, MO in late February of 1862, sent to Alton Prison and exchanged on March 10, 1862. He was elected Major on April 15, 1862. When Coleman's Cavalry was dismounted he was briefly in Company D of the 10th Missouri Infantry Regiment before being transferred to Pindall's Sharpshooters. He is buried in Dent County, Missouri.

Thanks again for the info.
