OK I saw in the TV a movie once but i was in a hurry and forgot to see or search its name later. I remember two scenes. It's an Asian (no its not porn) war movie in the Shogun eras(well maybe not these eras but they were ancient, you know what I mean) relatively new 2007-2010.Here are the two scenes.
1) The enemies engaged each other on the battlefield at sea and were in firing range. The first enemy started firing arrows but the second enemy's ships were decoys. So the first kept firing arrows until the enemy ships were covered with them. The second ship's commander (probably) was inside in one of the decoy ships and he was laughing and drinking his drink. That's the first scene I remember.
2) Here there were men standing above the map preparing for a battle at sea again. they were planning to destroy the enemy with fire but couldn't predict the course of the wind. As they had placed the figures of the ships on the map, on guy placed fire on them to tell the others how they would win. But one other guy with a sudden move changed the course of the fire to show how they would lose if the wind changed course.

That's all I remember. I know it's not much.... I hope you can help...
