A North American Indian tribe, part of the Iroquois Confederation, which originally dwelt in the Mohawk River Valley, N.Y., but was forced to flee to Canada for having sided with the Loyalists during the American Revolution.
The second Mohawk was built as Caledonia by Teas & Birely, Philadelphia, Pa.; launched 11 June 1853; chartered by the Navy 13 September 1858; and entered service soon after, Comdr. Augustus L. Case in command.
Mohawk sailed at once for South America to take part in Flag Officer William B. Shubrick’s 18‑ship expedition against Paraguay, attempting to gain satisfactory apology for the 1855 firing upon survey steamer Water Witch. Arriving Asuncion with the squadron 25 January 1859, Caledonia took position above Rosario in La Plata River, ready for operations while negotiations were conducted. Paraguay agreed to apologize for the incident and pay an indemnity.
The steamer returned to the United States in February, was purchased by the Navy 14 June 1859, and renamed Mohawk on that date. She commissioned at New York Navy Yard 19 September 1859, Lt. T. A. M. Craven in command.
Mohawk operated against pirates and slavers off the east coast and in the Caribbean through 1861, capturing slave ship Wildfire in Old Bahama Canal 26 April 1860, and delivering the prize to Key West where the crew was imprisoned. The 530 Africans on board were placed in a camp for protection, guarded by Mohawk’s marines, until they could be returned home. From 15 November on Lieutenant Craven in Mohawk with steamer Wyandotte defended Forts Jefferson and Taylor at Key West, Fla., from actions of "bands of lawless men”, a farsighted action that enabled the Union to retain that vital Florida base, so valuable during the forthcoming naval operations in the Civil War.
The steamer remained on guard at Key West until the end of January 1861 and then sailed for New York. On 11 March 1861, Mohawk departed for the Caribbean, escorting supply ship Empire City to Havana and then Indianola, Tex. The warship proceeded to Pensacola via Havana and Key West, arriving 10 May and took up her blockade station off that port. She next moved on to patrol off St. Marks, Fla., capturing sloop George B. Sloat 5 July attempting to run the blockade. She remained on station until sailing for New York 8 April 1862.
Two and one‑half months later, Mohawk sailed for Port Royal, S.C., to join Flag Officer Samuel F. DuPont’s South Atlantic Blockading Squadron. She returned to Port Royal in June 1863 for duty as guardship. Ordered north for repairs 27 June 1864, on 6 July she reported to Commodore E. K. Stribling at Philadelphia Navy Yard. Mohawk’s old and damaged boilers with her poor general condition from wartime use proved her unfit for further service. She was sold 12 July 1864.
