Miltiades biggest contribution was to the battle at Marathon which was considered a significant impact on the Persian wars. It was in the battle at Marathon where he showed both witt and skill against the Persian army. He was considered valuable to the athenians because of his former close relations with the Persian army, which meant he knew there tactics and there ways to which they fought in battle. The Athenians made Miltiades 10th Commander to which each day starting from commander one every commander would be given a chance to be in charge of the army.
It was Miltiades who saw the fact that the Persian cavalary wasnt their as an advantage and to which could result in victory if the Athenian army attacked early. So Miltiades convinced Calimuchus the Polemarh to confront the Persian army and give him command. Miltiades battle tactics were both thoughtful and strategic as he used what he had learnt about the Persians against them with both ingenious and thoughful ideas.
He made use of the terrain by placing his army on the top of the hill so that they had the higher ground and the best spot for when they made there way down hill so they were less tired and exhausted. It was said to be Miltiades who convinced the generals not to use their customary tactics of which hoplites (soldiers of greek cities) normally marched in an evenly distributed phanlanx of shields and spears. Miltiades was the one who had this great idea of attacking while the cavalary was not around.
His other contribution in the battle at Marathon tactics was the fact that he knew the Persians used arrow man. So miltiades had to think of a way to make it as if the Persian arrowman werent much help in inilation at all. This is the tactic i believe that sets him apart from every other commander; he made his army run into battle. as soon as miltiades army was in range of arrows he had them sprint and avoid the arrows, which this plan left the Persians dumbfounded.
But as i write how genius he was i know that Munro points out that it was Miltiades who understood the Persian way of doing thins, it was Miltiades who understood his strengths and weaknesses, and Miltiades who proved to be the master of timing, waiting for just the right time to act. Miltiades was seen as the one to seize the best position and knew just when to take the offensive. But I see another person who was of even larger importance to the contribution of the Persian wars and his name is Themistocles.
