Ships are located by clicking first in the top coordinate, and then in the left.  A torpedo will be fired at that coordinate.  If it hits a ship you will hear the explosion.  If it misses, there will be no sound.  Below are the pictures of both a hit and a miss.  The missle remains intack if there is a miss.

When all grid squares of a ship are hit the crew members will abandon ship as it sinks.  You will hear a whooping siren while the ship is being abandonded.  Hitting all your opponent's ships wins the game.
