Hetzel, a sidewheel steamer, was built in 1861 at Baltimore, Maryland, for the United States Coast Survey and was transferred to the Navy Department 21 August 1861.
Her first taste of action came 2 December, when Confederate steamer Patrick Henry stood out into Hampton Roads and engaged several Union gunboats, including Hetzel.
Arriving 4 January 1862 off Hatteras Inlet, Hetzel got underway with the fleet 5 February for the joint amphibious assault on Roanoke Island.
She took part in the initial bombardment of the Confederate works 7 February, and, after the landing of troops under cover of naval guns, helped to consolidate the Union victory next day.
Commander Rowan's forces quickly capitalized on their important victory by pursuing the retreating Confederate squadron up the Pasquotank River.
