Secessionville
Against Hunter’s explicit orders, Brigadier General Henry Benham threw his troops at the Confederate battery across the narrow neck at Secessionville at daybreak. The approach was a strip of ground a hundred and twenty yards wide between marshes, swept by a 8-inch columbiad loaded with canister. The Federals lost around 700 men in a few hours and gained nothing. Benham was arrested and lost his commission.
