"...a cleared space was found, overlooking deep ravines in which trees had been chopped down and left as they fell, and on the opposite side of which the newly thrown up works of the enemy (Fort Desperate) were plainly visible. The two leading batteries moved at once to this spot and opened fire in a space hardly large enough to afford the room for one battery. The enemy had its range perfectly, and their guns opened upon the head of the column (Union troops) as it appeared, creating fearful slaughter. Here Battery A in a very short time had two men killed, Lieutenant Humphrey and eleven men wounded, fifteen horses killed and two pieces (cannons) disabled."Lieutenant William L. Haskin
