Which battle can we consider to have been the most important turning point in the Greco-Persian wars?

        The Greco-Persian wars of 498 BC to 448 BC were a clash between two completely contrasting cultures. The Achaemenid Persian Empire stretched from the subdued Ionian Greek city states on the shore of Asia Minor to the Indus River bordering India and was ruled zealously by God-Kings in Persepolis, the capital of the Empire. On the contrary, the land we now know as Greece was a collection of small, aggressive city states that managed to put aside their many differences, and, against the overwhelming odds stacked against them, turned back the might of the Persian army from within their own territories. The Hellenic city - states that fought against the Persian Empire certainly defied the odds, but when and how did the tide change? Most Historians agree on a number of battles between 490 and 479 BC, but opinion is still somewhat divided as to which battle provided the exact turning point from the initial dominance of Persia to the Hellenic city states gaining the upper hand. In this essay, I will investigate the four key battles of Marathon, Thermopylae, Salamis and Plataea and will attempt to explain their significance within the war.

        The battle of Marathon took place in the late summer of 490 BC, during the first Invasion of Greece, organised by King Darius I. When Persian troops landed at Marathon en masse, the Athenians debated whether to stay behind their walls or come out and show their faces to the enemy. After much debate in Athens, the citizens voted according to Miltiades (Burn, 1962: 241) and decided to front up to the enemy where they had landed at the bay of Marathon.

        What is also interesting is that (aside from the 600 Plataeans) Athens stood alone in this battle. Sparta was willing to send troops to support the Athenians in battle, but Pheidippides returned from Sparta saying that the Spartans could not march until the full moon had risen - signalling the end of the religious festival of Carneia (Burn, 1962: 240. This would taken at least a week (Holland, 2006: 187-90), and so the Athenians would have had to have stayed put at Marathon. When they arrived, the Athenians secured the two exits towards Athens from the battlefield before the Persians could, thus protecting Athens (Burn, 1962: 243).

        The Athenians were joined by a small contingent of allied Hoplites from the polis of Plataea, which took the Greek troop number to 10 or 11,000 (Lazenby, 1993: 54). Depending on interpretation, the Athenian camp was protected on its flanks either by woods or by tree trunks cut down, so as to protect them from Persian cavalry (Burn, 1962: 243; Lazenby, 1993: 56). Whatever the correct interpretation, it should be noted that the Athenians knowledge of the battlefield and the planning of their position acted as a force multiplier.

        For the Persians, Marathon was chosen specifically for its suitability for cavalry; something other potential landing sites didn't offer (Burn, 1962: 245). The location of Marathon meant that if Datis had achieved victory there, he could have quickly marched onto Athens. It was also an ideal location to send ships around the Cape of Sounion (Burn, 1962: 245) and attack Athens while it was undefended.

        For five days, both Armies were kept confined to their camps.on either side of the battlefield. The Greek camp were happy to wait for the Spartan reinforcements to start marching, while Datis was waiting for a signal from Hippias' contacts within Athens to inform them that Athens was indefensible (Burn, 1962: 246). After 5 days, the stale-mate ended.

        Datis attempted to withdraw his cavalry during the night in order to encircle and attack the undefended Athens; however, this attempt at deception didn't go un-noticed to the Athenians (Burn, 1962: 247). This theory agrees with Herodotus' suggestion that the Persians tried to sail around Sounion and attack Athens after the battle had been lost (VI, 115). Greek hoplites were very vulnerable to attacks on their flanks and their rear, because of the nature of their static line. Since the cavalry were easily able to do this, and they had been removed from the field of battle, it was a tactical relief to the Athenians.

        Another theory suggests that the Persians simply moved their lines towards the Athenians, implying that they attacked first. However, the Athenians thought the Persians were attacking, not merely advancing and decided to attack them head on, thus taking the tactical offensive - which would still fit with the general agreement that the Athenians attacked first (Burn, 1962: 248). The view of the Athenians making the first strategical and tactical advance is supported by Herodotus account of the Council of War (VI, 110), which shows Miltiades winning the vote of Callimachus and adopting an aggressive stance against the Persians (Burn, 1962: 246). If the Persian army hadn't actually advanced towards the Athenian line in the first place, then the Athenian advance would have definitely taken the Persian army by surprise (Burn, 1962: 249). Therefore the Persian troops would have been fairly disorganised and mentally unready for battle.

        The Persian front line was 10,000 strong anyway; therefore the Athenian line had to spread out just to meet it (Lloyd, 1974: 191)! As a consequence, the hoplite ranks within the centre (commanded by the future statesmen Themistocles and Aristides) of the line were only four men deep, yet the Plataeans (led by Arimnestus) on the left and Callimachus of Aphidna, the polemarch, on the right had the normal compliment of an eight man deep phalanx. Burn suggests that the flanks were made stronger to prevent being enveloped on the flank (1962: 248-9).

        Another benefit of this tactic, which may or may not have occurred to Miltiades, was that if the flanks broke through their Persian counterparts, then this would prevent the enemy from fleeing outwards and would allow them to surround the enemy. As it happens, the Persian flanks consisted of lighter armed archers (who were easily crushed), yet the Persian centre contained better troops - the native Persians and the Sakai, who were the most trusted contingents in Persian battle (Burn, 1962: 250).

        As the Greeks chose to charge the Persians (Burn, 1962: 248), their archers were only able to let off one or two volleys of arrows before they were impaled upon their rushing Athenians spears. The slaughter upon impact would have been terrible. As it happens though, the Persians on the centre managed to push the Athenians back (due to the weak Athenian centre). The names of slaves within the battle obituary may indicate that the Persians broke through to the Athenian camp and killed slaves skirmishing behind the hoplites or slaves within the camp itself (Burn, 1962: 250).

        However, the wings of the Greek army succeeded in routing their opponents and after doing so, paused before turning inward to surround the Persians troops in the centre. Once the Persians realised they were surrounded, their centre routed as well and fled towards their ships. The subsequent pursuit by the Greeks resulted in a few casualties as they attempted to capture Persian ships, including the polemarch Callimachus (Burn, 1962: 251). Many fleeing Persians were killed by running into the Marshes to the north of the battlefield, which Pausanias informs us of (I, 15, 4).

        Marathon was an impressive victory ...
