This is a curious item of interest:Â 18th century cannon in NYC found to be loaded with ammo
Recently, a Revolutionary era cannon from a British warship that had been on display in Central Park  until the mid-90’s in New York was found to loaded during restoration efforts.  The cannon was apparently loaded with 2 pounds of black powder and a cannonball.  It was disarmed by the NYPD Bomb Squad after the police were notified.  The powder is claimed to have still been viable.  Now wouldn’t that be a hoot if somebody had figured that out while the cannon on was still on display and fired it.  Would we consider anybody injured a Revolutionary War casualty since that is when the cannon was loaded?
