Mullan, D. W.

USS Monongahela was among 18 Union vessels under Admiral Farragut's command as part of the West Gulf Blockading Squadron, bombarding Confederate forts in Mobile, Alabama, and then ramming CSS Tennessee. Combined heavy gunfire from the other Union ships forced Tennessee to surrender, ending the battle and closing the last major Gulf port to the South.
