There was an amazing Korean drama or movie but I cannot remember its name, and only one scene is stuck in my mind: there was this huge uneven fight with ships, with some amazing manoeuvres, whirlpool and a woman waving from the rocks to warn about a sudden attack from behind!

PLEASE HELP ME if anyone can think of the name!
