The defenders were also distracted by the appearance of four vessels from the Blockading Squadron: the steamers USS "Daylight", "State of Georgia", and "Chippewa", and the bark "Gemsbok". Until this time, the Navy had not been involved with the siege, but Commander Samuel Lockwood responded to the sound of gunfire and brought his section of the fleet into action. The weather was not good for a naval bombardment, however; a strong wind created waves that caused the vessels to rock badly enough to disrupt their aim, and after about an hour, the fleet withdrew. The Navy also supplied a pair of floating batteries to the attack, but again the waves interfered, and only one of them got into action. It is not certain whether the fort sustained any hits from the ships. The Confederate return fire was accurate enough to hit two vessels, doing little damage and slightly wounding only one man.
