The monitor USS Montauk deep-sixed the blockade runner CSS Rattlesnake (identified here by one of its older names, the Nashville) on February 28, 1863, in full view of Fort McAllister. The Montauk was undamaged by fire from Fort McAllister, heated- or un-, but managed to steam into a Confederate mine, which did take her out of action for a month for repairs.

The Montauk would go on to participate in Admiral DuPont's not-particularly-effective attack into Charleston Harbor on April 7, and at the end of the war was at Washington Naval Yard, where it served as the floating prison for six of John Wilkes Booth's "fellow conspiritors" in the assassnation of President Lincoln. Booth's autopsy was also carried out aboard the Montauk.
