Battle of the Head of Passes

The Battle of the Head of Passes was a bloodless naval battle of the American Civil War. It was a naval raid made by the Confederate river defense fleet, also known as the “mosquito fleet” in the local media, on ships of the Union Blockade squadron anchored at the Head of Passes. The mosquito fleet was supported by three fire rafts, which were ignited and followed the ironclad ram CSS Manassas into the action. The attack occurred after moonset in the early hours of October 12, 1861, and routed the Union fleet, which fled in disorder down the Southwest pass of the delta. After sunrise Commodore George N. Hollins ordered the mosquito fleet to withdraw upriver.^:84-94
