[1] The wooden steamer departed Boston on 24 February 1862 for the Gulf of Mexico, but heavy winds, rough seas, and engine trouble required her to stop at Charleston, South Carolina, for repairs.

During operations along western Gulf coast in September and October, Kensington captured British blockade running schooners Velocity.

Kensington began her voyage to Pensacola, Florida, with her prizes 13 October, delivering water en route to blockading ships stationed along the coast of Texas.

Back in fighting trim by 1 August 1864, Kensington functioned as a supply vessel for ships of the North Atlantic Blockading Squadron until 30 November.

She sailed from Boston as a transport vessel on 7 December visiting Port Royal, Key West, Florida, Mobile, Alabama, Pensacola, and New Orleans.
