The Baltimore or Winans Steam Gun - Civil War

At the start of the Civil War, a bullet proof "steam gun" was patented by Charles Dickinson and worked on in Ross Winans foundry in Baltimore.  Dickinson was on his way to sell it to the Confederacy, when it was captured in Ellicott City by Col. Jones and the 6th Mass. It was kept at Relay to guard the Thomas Viaduct. The muzzle of the gun/cannon protruded from the slit of the cone (see below) and it was dragged by a team of horses.  A large replica can be seen at Elkridge.
