The 20th Virginia Cavalry Regiment was made up of men from what is now the State of West Virginia.

The makeup of the 20th was as follows:
Companies A and B from Marion and Monongalia Counties, Company C from Highland and Randolph
Company D from Highland and Barbour
Companies E and F from Harrison
Company G from Wood and Pleasants
Company H from Calhoun, Richie, Wirt
Company I from Bath

Co. I, raised in Bath County. Commanded by Capt. Henry Heiskell

Shortly after the Battle of Droop Mountain most of the 19th Va. Cav. was merged into the 20th Virginia Cavalry so essentially the two regiments are one and the same.
