However, Coehorn mortar shelling and devastating enfilade musket fire from the deeply echeloned government forces killed those who had made a breakthrough, while the others, after suffering heavy casualties, fell back in a retreat that quickly became a rout.
The battery—the heaviest used in the wars of 1863-64—included a 110-pounder Armstrong gun, two 40-pounder and two six-pounder Armstrongs, two 24-pounder howitzers, two eight-inch mortars and six Coehorn mortars.
