These three pictures are all supposed to be the CSS Ellis, yet the first and second ones are very different. Notice the rounded bow of the ship above. The ship below has a much sharper bow than the one seen to the left and has no raised pilot house.
There is a line running from the mast to the bow in the picture above. No such line is to be seen in the other two. However, the picture does show a small gun at the rear; the Ellis had an 8-pdr. gun at her stern. This drawing shows her at Roanoke Island following her capture.
The corner of the pilot house in the picture above looks similar to the second drawing. I can trace the origins of the second and third drawings. The artists were definitely present in northeastern North Carolina at the time the drawings were made.
