Matthew Fontaine Maury, the intrepid astronomer turned Confederate won the final "Greatest Civil War Naval Officer" Quarterfinal Poll. A brief biography of Matthew Fontaine Maury can be found HERE, courtesy of the Naval History and Heritage Command.
Thus, the "final four" naval officers will square off each other to determine who will represent their respective organizations in their final round. David Dixon Porter will go up against William Cushing for the Union Navy, and Matthew F. Maury will be pitted against Raphael Semmes in this week's semifinal polls for the Confederate side. BOTH polls will be available to vote on the website, and will be up a few days longer than normal.
