She was commissioned on April 17th, 1864. It is said that the last of the armor plate was attached as she steamed down the Roanoke River. On April 19th she lead an attack on the Union forces at Plymouth, N.C., during which Southfield was rammed and sunk and Miami, Ceres, and Whitehead were forced to withdraw. Plymouth surrendered to the Confederate forces the next day.

Picket Boat Number One, a steam launch, was built in
1864 for use in support of the U.S. Navy's blockade of the Confederacy.
Outfitted with a spar-torpedo, she could also be employed to attack
larger enemy vessels. On the dark night of 27-28 October 1864,
Lieutenant William
B. Cushing and a crew of 14 men took Picket Boat Number
One up river to Plymouth, North Carolina. In one of the Civil
War's most daring naval actions, they attacked the Confederate
ironclad Albemarle,
sinking it with the spar torpedo. Only Lt. Cushing and one other
man escaped, and Picket Boat Number One was lost, but the
Union forces on the North Carolina sounds were freed of the great
threat presented by the continued existence of the Albemarle.
Albemarle was raised after the Union forces captured Plymouth. In late April 1865, she was towed to Norfolk Navy Yard by USS Ceres. There she was condemned as a prize, and purchased by the Navy who sold her in October 1867.
