The USS Congress was a United States Navy frigate launched at Portsmouth Navy Yard on August 16, 1841, and commissioned on May 7, 1842, under Captain Philip Voorhees. She measured approximately 1,200 tons displacement and was powered by sail, typical of mid-19th-century warships. Her service life spanned two decades, during which she served in various theaters including the Mediterranean, South Atlantic, and Pacific Oceans, playing significant roles in both diplomatic and military operations. Initially, Congress's first cruise took her to the Mediterranean with the Squadron of Commodores Charles W. Morgan and Charles Morris. She later joined Commodore Daniel Turner's Brazil Squadron to blockade Montevideo during the Uruguayan Civil War. Notably, in September 1844, she captured an Argentine schooner delivering mail, an action that temporarily strained U.S.-Argentina relations. After a period in ordinary at Norfolk in March 1845, she was recommissioned in September of that year, serving as the flagship of Commodore Robert F. Stockton and sailing to the Pacific. During the Mexican–American War, Congress actively participated along the west coast, supporting landings and battles at Rio San Gabriel, La Mesa, Los Angeles, Guaymas, and Mazatlán. Her duties extended to protecting U.S. interests along the South American coast, notably serving as flagship of the Brazil Squadron from 1850 to 1853. She returned to the Mediterranean and later operated again in South American waters before returning to Boston in 1861. In the Civil War, USS Congress was part of the Union blockade of Virginia. Her service ended tragically during the Battle of Hampton Roads on March 8, 1862, when she was attacked by the Confederate ironclad CSS Virginia (ex-USS Merrimack). After a fierce exchange of broadsides, Congress was forced to surrender after suffering extensive damage, 120 casualties—including her commanding officer—and her magazine exploding. The ship burned to the water's edge and sank in shallow water. Raised in 1865, she was subsequently sold and stripped for salvage, with her wood used to create a memorial flag. The USS Congress remains a notable vessel for her active service in multiple conflicts and her role in the early evolution of naval warfare.
