The Battle of Hatteras Inlet Batteries (August 28–29, 1861) was the first combined operation of the Union Army and Navy in the American Civil War, resulting in Union domination of the strategically important North Carolina Sounds.
Two forts on the Outer Banks, Fort Clark and Fort Hatteras, had been built by the Confederates to protect their commerce-raiding activity. These were lightly defended, however, and their artillery could not engage the bombarding fleet under Flag Officer Silas H. Stringham, commandant of the Atlantic Blockading Squadron, which had been ordered to keep moving, to avoid presenting a static target.
