About the Lecture

John Dahlgren was a naval ordnance officer who invented a boat howitzer and the famous Dahlgren naval shell gun. Six IX-inch versions were employed aboard CSS Virginia, and two XI-inch guns were mounted on USS Monitor. Dahlgren also designed the XV-inch shell gun, which, when used in the turrets of subsequent monitors, could destroy Confederate ironclad casemates, a breakthrough in naval warfare.
