- Naval Gunnery in the Old Days
An 18-ton gun in action at the bombardment of Alexandria. The gun has just recoiled after firing. No. 1 is "serving the vent". The sponge end is being passed to be thrust out of the small scuttle in the middle of the port (which is closed as soon as the gun is fired), so that the big wet end can be placed in the gun. - Submarine Mine laid by the Russians in the Crimean War
