Unsuccessful in efforts to destroy her by long-range fire from Metacomet and Monongahela, Admiral David Farragut ordered a boat expedition to attempt the task.

In the ensuing battle Metacomet and other Union ships captured Confederate ram CSS Tennessee, a major threat to the blockaders at Mobile.

[2] After offloading the wounded, Metacomet steamed to the Texas coast and captured blockade runner Susanna off Campechy Banks on 28 November, and took schooner Sea Witch and sloop Lilly off Galveston on 31 December 1864 and 6 January 1865, respectively.

Mines, then called "torpedoes", remained a danger to shipping in waters near Mobile, so Metacomet returned there to drag the Bay and Blakely Channel from 9 March-12 April.

Returning north after the end of the conflict, Metacomet decommissioned at Philadelphia on 18 August and was sold there to John Roach & Sons on 28 October.
