USS Phlox

USS Phlox was a steamer commissioned by the Union Navy during the American Civil War. She served the Union Navy's struggle against the Confederate States of America as a gunboat; and, after the war's end, she served the midshipmen at the United States Naval Academy in Annapolis, Maryland, as a training ship.

Assigned to the North Atlantic blockade
Assigned to the North Atlantic Blockading Squadron, Phlox steamed south late in September and operated in the James River helping maintain communications among the Union ships, supporting General Ulysses S. Grant’s operations against Richmond, Virginia.

In January 1865 she steamed to Wilmington, North Carolina, to support the joint Army–Navy attack on Fort Fisher, North Carolina, which doomed Wilmington.

After Fort Fisher fell, Phlox returned to the James River where she served through the end of the war.
