Remember, this happened over 2,000 years ago, roughly 2,500 years ago. So it's amazing that we know anything about it at all. And obviously we have to rely on Herodotus and whatever historical accounts we can find. So the Persians are invading by land and sea. And the Greeks have a strategy of let's try to stop them by land at Thermopylae and stop them by sea at the Strait of Artemisium, right over here. And there's some historical debate of, you know, was this a big, grand strategy to eventually try to defeat the Persians at Salamis, which eventually happens? Or were they, you know, genuinely trying to stop them there and because they couldn't, they had to retreat back to Salamis?
