The second Cyane , a sloop, was launched 2 December 1837 by Boston Navy Yard. She was commissioned in May 1838, Commander J. Percival in command.
She sailed 24 June 1838 for duty in the Mediterranean, returning to Norfolk 16 May 1841. She cleared 1 November 1841 for the Pacific Station, returning 1 October 1844. Sailing again for the Pacific 10 August 1845, Cyane served on the west coast during the Mexican War. On 7 July 1946 her commanding officer, Captain W. Mervine, led a detachment of Marines and sailors from Commodore Sloat's squadron ashore at Monterey, Calif., hoisting the American flag at the Customs House and claiming possession of the city and all of upper California.
On 26 July 1846 Lieutenant Colonel J. C. Fremont's California Battalion boarded Cyane , now under the command of Commander S. F. DuPont, and she sailed for San Diego 29 July. A detachment of Marines and sailors from Cyane landed and took possession of the town, raising the American flag. They were followed shortly by the Fremont volunteers and Cyane 's detachment returned aboard to sail for San Blas where a landing party destroyed a Mexican battery 2 September.
Entering the Gulf of California, Cyane seized La Paz and burned the small fleet at Guaymas. Within a month she cleared the Gulf of hostile ships, destroying or capturing 30 vessels. In company with Independence and Congress , she captured the town of Mazatlan, Mexico, 11 November 1847. She returned to Norfolk 9 October 1848 to receive the congratulations of the Secretary of the Navy for her significant contributions to American victory in Mexico.
Between 9 October 1851 and 24 June 1852 Cyane sailed in the Home Squadron, rejoining it 10 October 1852 to cruise constantly on the Atlantic coast and in the Caribbean from Nova Scotia to Aspinwall for the protection of the lives and property of American citizens. She bombarded and destroyed Greytown, Nicaragua, 13 July 1854 in retaliation for outrages against American citizens there, and protected the disputed fisheries along the coast of Nova Scotia from 2 September to 30 October 1857. She sailed for Haiti 19 November 1857 and joined a special expedition surveying the Isthmus of Darien as a possible site.
In August 1858 Cyane stood out for the Pacific, and except for necessary overhauls, was constantly employed on the coasts of North and South America until decommissioned and placed in ordinary at Mare Island Navy Yard 20 September 1871. She was sold at auction 30 July 1887.
