On 8 February 1853, the gunboat set sail from Norfolk, Virginia, for an extended exploration and survey voyage along the Atlantic coast of the southern portion of South America and of the rivers which drain that part of the continent. Over the next few years, she conducted surveys of the rivers in Paraguay, Argentina, and Uruguay. In February 1855, while the little steamer was surveying the Río de la Plata basin, she was fired upon by the Paraguayan Fort Itapirú. The bombardment killed one member of her crew (helmsman Samuel Chaney) and ended her surveying mission on the river. The gunboat, however, continued her mission in other areas of the southeastern coast of South America until 1856. On 8 May 1856, she returned to the Washington Navy Yard for repairs and went out of commission on the 12th.
