Queen Elizabeth's Pocket Pistol, Dover Caste, Dover, Kent. "Load me well and keep me clean, I'll carry my ball to Calais Green.". This artillery piece is a cannon built in 1544 in Utrecht by Jan Tolhuys, before Elizabeth I came to the throne. The gun was presented to Henry VIII by Maximiliaan van Egmond, Count of Buren and Stadtholder of Friesland as a gift for his young daughter Elizabeth. In 1644, the gun saw action at the siege of Hull and the Siege of Sheffield (having been recaptured by the Roundheads).
