Overnight, Du Pont's flagship USS "Wabash" detached 100 crew to man four of the 30-pounder Parrott rifles. In the morning, with the wind picking up right to left and affecting shell trajectory, the Union artillery resumed the bombardment, concentrating fire to enlarge the opening. The Georgia gunners again found targets, described in dispatches as Rebel "firing ... good all the morning, doing some damage". At the same time, the Parrott rifles and Columbiads opened a great gap in the wall, sending shot across the interior of the fort and against the northwest powder magazine containing twenty tons of powder. Regarding his situation as hopeless, Olmstead surrendered the fort at 2:30 p.m. that day.
