How did the Greeks plan to defend against the Persian invasion in 480 BC?

A look at the problems faced by Sparta, Athens and the other allies when faced with Xerxes' invasion in 480 BC. We talk about the army sent to the Pass at Temkpe as well as the later - and far more famous - defence of the Pass at Thermopylae.
