13th Ohio Cavalry

Editor’s Note: Do you have information on this unit’s role at the Siege of Petersburg?  Please contact us using the Contact button in the menu at the top of the screen.  We are happy to exchange information with other researchers.

Note: This unit served as infantry at the Siege of Petersburg until December 10, 1864, at which time it was transferred to the Army of the Potomac’s Cavalry Corps.  It is categorized as infantry because it spent more time in that arm of the service than in the cavalry.

Muster In: Organized by a consolidation of 4th and 5th Battalions Cavalry, and mustered in May 5, 1864.1
Muster Out: Mustered out August 10, 1865.2
