One rule that had an effect on the outcome was using "command points" for the Persians. At the start of their turn the Persians threw 1 AvD for every five units in their command, the resulting score being the number of units that could move that turn. We had used a similar system for Marathon as a means of reflecting the greater cohesion and better command and control of the Greeks. At Plataea the Greeks were clearly not as co-ordinated and decisive as they'd been in that earlier encounter. However, I still felt that their more compact and better trained army gave them an advantage over the polyglot Persians.
(Athenian support begins to arrive as the Persian infantry struggles to get to grips with the Spartans. Figures are mainly Garrison 20mm, though the caped foot commander waving his sword in the far distance is from Phoenix Model Developments. His cast on sword fell off and had been replaced with a pin, making him quite a dangerous little chap to handle)
Greeks opposed by a whopping 596 Persians. Even the generals were dying on
the field. The exhausted Greeks retook the Asopus ridge but lost all
their lights while 7 out of 12 phalanxes were too battered to continue. Of the three
reinforcement phalanx units one arrived on the first throw of the
dice - the other two did not appear at all. The Persians and their allies were
reduced by the end to a handful of mounted and light infantry units. The
Immortals fought magnificently but proved mortal, the horsemen kept
getting behind the Greek lines, the Helots manfully kept the heavier
troops protected at huge cost and the commanders risked all and paid
continuous violence broken only by a brief pause to munch on some ginger nuts. After much bloodshed and some spectacularly lucky dice throwing by a unit of Assyrian spearmen, the Spartans were driven from the Asopus, before the advancing relief could arrive. Alas for the Persians the vast number of units they had at their disposal and poor command and control (how many 2s can you throw on an AvD?) slowed down all movement and they were unable to reinforce this success, before the Athenians arrived and hammered the depleted units on the ridge. A second wave of Persian troops proved less effective than the first. The toll amongst the generals was fearsome. Mardonius died while attempting to rally some Mede Infantry, Pausanius was cut down by Persian lancers and Aristedes of the Athenians was killed just as the Greeks claimed victory by a stray arrow from some marauding Dahae horsemen.
