There are so many ships, whichs every single plank simply drowned in blood, in that old times. In whichs deep stomach hundreds of people spilled their soul out, or died while being carried into slavery and doom.
For money, or just the last words, there were thousands murdered, and billions *just* drowned in the sea.

Don't tell me that there is nothing left from them.
