John Gwinn Also Commanded the Frigate USS Potomac

Last month I spent a lot of time writing about this naval officer's career.  He was a War of 1812 veteran and was commanding the frigate USS Constitution at the time of his death in 1849.

He also commanded the frigate USS Potomac from 1844 to 1845.

The frigate USS Potomac was constructed at the Washington Navy Yard between 1819 and 1822 and entered active service in 1831.  During the 1830s and early 1840s, the Potomac sailed to Asia where it participated in the shelling of  Qualla Battoo, Sumatra.

After its return to Boston in 1844. the ship traveled twice to Brazil

Captain John Gwinn of Maryland commanded the ship  between October 1844 and December 1845 as the Potomac sailed along the U.S. Atlantic coast and to ports om the Caribbean and Gulf of Mexico.

During the Mexican War, the Potomac landed troops at Port Isabel, Texas, and in the Siege of Vera Cruz.

From 1855 to 1856, it was the flagship of the Home Squadron and was part of the Union blockade of the Gulf Coast during the Civil War.

It remained in the service of the U.S. Navy until 1877 when it was sold.
