The USS Underwriter participated in Burnside’s Expedition. She was present at the battles of Roanoke Island and Elizabeth City. She was sunk at New Bern, NC, in 1864.
This is “The Confederate Soldier in the Civil War” version of the Underwriter. Notice the two masts. Did the Underwriter have masts? She was a tugboat in New York, after all, not a sea-going vessel.
