There are few records on the service of Hiram E. Barstow, with the exception of his leadership in the Union command at the Battle of Clark's Mill. In November 1862, Capt. Barstow sent a detachment southeast of Gainesville to verify the presence of Confederate forces. Barstow'³ men ran into and pushed back a Confederate force. His column fell back to Clark'³ Mill where he learned that another Confederate force was coming from the northeast. Barstow was soon engaged in a five-hour fight, which ultimately resulted in the surrender of the Union forces.
