I recieved a request to do something on American Civil War naval history. Sorry it's a little late! Hope this is what you wanted!
During the Civil War, the Union navy strategically blocked off the Confederacy's access to supplies via waterways. In order to distract them, the Confederate navy Union commercial ships in the oceans. The CSS Alabama, one of these ships, was eventually taken down by the USS Kearsarge, which is the confrontation shown here. Obviously, I made some exaggerations. The ships were each manned by more than one guy pointing at the other ship, for instance.
