I read this a few months ago with the MC being a greek mercenary. I think his name was Davy and he uses the title Chosen of Hades to explain his knowledge. He was sent back in time and so uses tactics and other knowledge to make a name for himself and eventually takes over the mercenary team. He fights with Persia and helps his team escape back to their home. Anyone know what it was called?
You mean Davos ? Hegemon of Mediterranean or something IIRC Edit : It's Mediterranean Hegemon of Ancient Greece
