R.J Wickersham raised a company in and around Laclede County in 1861, took it south to Arkansas wher it was disbanded / re-organized or consolidated with Robert Woods unit in the Missouri State Guard. When the MSG was broken up he joined regular Confederate service initially as a Capt. with Company A, Woods Regt CSA (13th MO Vol Cav), Promoted sometime in 1862 to Major and then Lt. Col. after Price's raid into Missouri which he took part in. He was paroled in Shreveport LA June 7th 1865. I can find no record of him being a POW / captured / exchanged. He did take part in battles at Springfield, Pea Ridge, Jenkin's Ferry and the aforementioned Raid. He does have a UDC record on file as well as being a member in good standing of the Frances Cockrell Camp #1220 of the UCV on July 26, 1902. I believe that camp was organized out of Lebanon, MO.

13th Missouri "Wood's" Cavalry CSA
Commonly nicknamed, "Wood's Regiment", this unit was originally designated the 14th Mo Cavalry Battalion. Later as the unit was increased to regimental size, it was redesignated as the 13th Mo Cavalry Regiment. It is also known as "Wood's Partisan Rangers", and was commanded by Col. Robert C. Wood. It served primarily as an "unattached" or independent unit, although it was assigned to Marmaduke's Cavalry Division. It saw action in the following battles: Pine Bluff, Ark. (Oct. 25, 1863), Jenkins' Ferry (April 30, 1864) and in the numerous engagements of Price's 1864 Missouri raid. The Regiment surrendered at Shreveport, LA and was paroled in June 1865. At the time of its surrender it was part of the 1st Missouri Cavalry Brigade, 1st Cavalry Division, Trans-Mississippi Department.
