This early Georges Melies film in a reenactment of events during naval combat in Greece: sailors come out of the hold and work the guns against enemy forces. By no means a particularly excellent piece, it can best be appreciated in the context of its own period: Melies sets the ship rocking back and forth against the background -- it seems to have been placed on rockers -- in what was, for the time, an unprecedented technique -- which is fairly typical for Melies, who worked as hard at his film illusions as he had on his stage illusions when he was a practicing magician.
For those who wish to see this piece with their own eyes, it can be found on the European Archives site.
