In a Submarine 1908 Dans le sous-marin

A submarine coming into port is seen gliding smoothly on the water and the little rowboat which is to bring the captain of the vessel to his post is seen leaving for shore. We see the dashing young officer bidding his love adieu, and then seating himself in the frail craft is soon once more on duty at the wheel. Away they go, and reaching the wide sea the ship gives a lurch and disappears under the water.
