They ram a shell into the breech, and rapidly close it. (The breech is equipped with an Ausbury mechanism for rapid opening and closing.) They continue to open and close the breech, loading multiple powder charges. Closeup from a different viewpoint of the gunners loading the gun, as a sailor at the gun maneuvering controls elevates the barrel with a hand crank
