The following text of Joseph B. Chambers service comes from the Lawrence County Historical Society Website:

Believed to be the county's only Congressional Medal of Honor recipient, Joseph B. Chambers, a member of Company F of the Roundhead Regiment, was sent ahead of a skirmish in advance of the line of battle. At the edge of a road, Chambers observed the Confederate colors, jumped over resting troops and grabbed the flag pole holding the enemy flag. When the color bearer rushed to regain the flag, there was a tussle. The Confederate soldiers did not shoot for fear of hitting the color bearer. Meanwhile, the Union soldiers advanced quickly and captured the large Confederate detachment. A short time later, Pvt. Chambers, already in possession of the enemy flag, stopped a Confederate officer and took his sword. Pvt. Chambers was the father of Judge James A. Chambers. (Photo courtesy of Mrs. James E.

Author's Note:  Both Congressional Medals of Honor were awarded for gallantry and bravery in front of Petersburg at the retaking of Fort Stedman, March 25, 1865.
