Survivors answer for the dead

Those who survived will answer for those who died. It's not written, but it's known. I came here prepared to die,, but here I sit trying to answer questions above my rank, beyond my understanding, and never; nowhere in my imagination.
Even how can one imagine what we saw. How do you name what is unknown. What do I tell them, man came out from bellies of wooden beast with wings Made of cotton. The men if they were, wore suits made of shinny metal. And when they yelled, there lances roared, killed many of our warriors from distance. In all that noise I could make out only one word, CORTEZ.
