The battery lost 1 corporal killed and five privates wounded.

General Gordon, the battery’s division commander, wrote

“…I take great pleasure in bearing testimony to the gallant conduct and efficient service of this battery in action. From the most unimpeachable testimony, I am convinced that this battery, unaided by its supports, kept at bay a furious but futile charge of the enemy. In this, as in many other cases, Captain Cothran has shown what a judicious artillerist can accomplish when he devotes himself to the service of his country and throws himself energetically into the discharge of his duties.”
