Try A. J. Riggins

See:

Battle of Riggins Hill
With Clarksville again in Confederate control, Union infantry left the town of Dover, west of Clarksville, on Sept. 5, 1862, with 1,050 men and two sections of artillery. Both armies met just outside of Dover and clashed head-on.

Rebel forces, greatly outnumbered, were pushed back toward what was then the town of New Providence.
In a series of delaying tactics, the rebels came to a small ridge on the property of Mr. A. J. Riggins. Many townspeople joined in what was later called the Battle of Riggins Hill. The fight continued on September 6 and 7, and the Confederates were pushed all the way back through New Providence and into Clarksville, which was retaken.
The town and fort were reoccupied by Federal troops who remained for the rest of the war.
Colonel Bruce was placed in command at Clarksville and Fort Defiance was renamed Fort Bruce.
