This is a refight of the battle of Plataea 479 BC.
After many days waiting and seeing the Greeks trying to retreat from the battlefield the Persian cavalry, figuring they would never have a better chance, charged forward towards the Spartan hoplites on the Greek right. Caught off guard, the Spartans were broken and not really wanting to be there anyway left the battlefield. A fantastic start for the Persians who started to wonder that things might have gone differently at Marathon if only they had had some cavalry there as well.
Grim faced, the Greek centre charged forward at the miscellaneous Persian allies positioned there, who were gaping open mouthed at the prowess of the Persian noble cavalry. Perhaps they were worth all the taxes they paid! Nevertheless, the Persian allies, every one of them an archer, had their own fight to fight now and, watched by the critical eyes of the Persian Immortals behind them, gave a demonstration of archery worthy of the Welsh longbowmen at Agincourt! The charging Greek minor states hoplites faltered, stopped and then retreated. The Gods were definitely against them today! Over on the Greek left the Athenians eyed the Greek mercenary hoplites on the Persian side, with both sides making rude gestures at each other.
The Persian archers in the centre opened fire at the Greek reserves as they moved to fill the hole left by the Spartans but were obviously too busy congratulating themselves to fire effectively at the new target. The Athenian hoplites, infuriated by a particularly obscene gesture, charged the hoplites opposite them and a right shoving match ensured with no advantage to anyone.
As Persian arrows continued to fall on them, the Greek reserves attacked the Persian cavalry on the right and drove them off the battlefield. These Greeks, having caught sight of the huge number of Persian reserves waiting behind the front lines, chose to pursue the nobles off the battlefield rather than face the might of the Persian Empire. And so on the Greek side there were only the Athenians left, who having exchanged blows and insults with their fellow but opposing Greeks, put their best foot forward in leaving the battlefield. A resounding victory for Persia leaving Athenian heads high but the Spartan reputation soured.
