Dictator: The 13-Inch Mortar of Petersburg
In 1864 a 13-Inch Seacoast Mortar, Pattern 1861, was used by the United States Army in the siege of Petersburg. The mortar was mounted on a railcar - named the Petersburg Express - and used against Confederate fortifications. The fame of this heavy mortar may be greater than it's impact upon the siege. Whether the "Dictator" is among the approximately thirty 13-Inch Mortars which survive to the present is a matter of conjecture.
