The Last Samurai (2003)

Revealing mistake: The road leading out of the samurai village has distinct tire tracks from vehicles.

Algren: Your highness... if you believe me to be your enemy, command me, and I will gladly take my life.

Trivia: All the ninja seen in the film were played by actual modern day practitioners of the ninjitsu arts. Allegedly this led to a running joke on set where if the ninja were rehearsing with a stunt double or an extra they would spontaneously perform a kill move (obviously stopping before actually hitting their opponent) then remind everyone they were only contracted to let Tom Cruise live through the movie. Everyone else, as far as they were concerned, was fair game.

Question: Nathan told Katsumo a story about the Greeks fighting a much smaller army and ended up losing the battle. Can anyone tell me the story or where to find the details on the web?
