Salamis (EDIT: Meant Plataea) > Thermopylae Thermopylae was basically the Persian Emperor running into a Spartan king and his elite guard and slaughtering all of them with not much resources spent while simultaniously conquering the most easily defended area in Greece. It's just a propeganda battle after the fact. Salamis was pretty darn epic though. By that point the Macedonian Phalanx was a shadow of it's former self thought. They'd long forgotten the "hammer" part of the "hammer and anvil" strategy that Alexander mastered. And the Macedonian state just didn't have the kind of infrastructure necessary to field a proficient army. 4th Crusade is the P4P funniest of all the Crusades. And that quite a statement when you have the 5th and the 7th crusade to content with. The Battle of Tours is a battle that we know next-to-nothing about except for the fact that it happened -- so we have no idea how it actually went down. Hell, we don't even know if the Franks were fighting an Umayyad raiding force or an actual Umayyad army.
