How Did the Greeks Win the Battle of Marathon?

The Long Wait For several days, the Greek and Persian armies faced each other across the plain. The Persians held the lower ground near their ships and the shore. The Greek army stood closer to the hills at the western side of the plain, where it could protect the road to Athens and avoid being easily surrounded. Between the two armies lay open farmland, with marshy ground near parts of the coast. The Greeks had good reason to be cautious. Persian armies relied heavily on archers, light infantry, and cavalry. On open ground, Persian horsemen could threaten the Greek flanks, while the archers could weaken the tightly packed Greek phalanx before the infantry met. The Athenians, however, had one great strength: the hoplite phalanx. Their soldiers were heavily armed with bronze helmets, large round shields, spears, and armour. If they could reach the Persian line quickly and keep their formation together, they could turn the battle into close combat — the kind of fighting that favoured them. Miltiades therefore needed to solve two problems at once. He had to protect his outnumbered army from being surrounded, and he had to cross the ground before Persian arrows could break his formation. The Greek Line Advances When the moment came, the Greek army moved forward. The exact reason for the timing remains debated. Some historians argue that the Persians had begun moving their cavalry or preparing to sail part of the army toward Athens. Others believe Miltiades simply saw an opportunity. What is clear is that the Greeks did not wait for the Persians to attack. They chose the moment themselves. Miltiades arranged the Greek line carefully. To prevent the Persians from outflanking them, he stretched his army across a wide front. This meant making the centre thinner than usual while strengthening the two wings. It was a gamble. A thin centre could be pushed back. But if the stronger Greek wings defeated the Persian troops opposite them, they could turn inward and strike the enemy centre from both sides. At the command, the Greeks advanced across the plain. Ancient writers describe them as running for the final distance, perhaps to shorten the time spent under Persian arrows. Exactly how far they ran and at what pace is uncertain. The Persian archers fired. Then the Greek line hit. The Centre Bends The collision was violent. The Persian centre, made up in part of the empire’s strongest troops, pressed against the thinner Greek centre and forced it backward. For a moment, the Persian plan appeared to be working. The Greek centre bent under the pressure. The men in the middle were outnumbered and could not match the weight of the Persian attack. Yet this did not immediately destroy the Greek line. The centre withdrew while still fighting, buying time for the stronger Greek wings to do their work. On both sides of the battlefield, the Greek wings began driving back the troops facing them. The Athenians and Plataeans were better protected in close combat. Their heavy shields and long spears gave them an advantage once the fighting became hand-to-hand. Persian soldiers fought with courage, but many were more lightly equipped and had less room to use their bows once the Greek line reached them. The Persian wings began to give way. The Wings Turn Inward This was the moment Miltiades had built the battle around. The Greek wings did not chase straight after the retreating Persians. Instead, they turned inward toward the Persian centre. The same Greek line that had been stretched thin at the beginning now folded around the enemy’s strongest troops. The Persians who had pushed the Greek centre backward suddenly found themselves attacked from the front and on both sides. The battle became a trap. The Persian centre could no longer advance. Its soldiers were crowded together, pushed from every direction, and unable to use their advantage in numbers. Greek hoplites drove into them with shields, spears, and swords. The Persian line broke. The Race for the Ships Once the Persian troops began retreating, the battle changed quickly. The survivors ran back toward the shore, trying to reach their ships before the Greeks could cut them down or seize the vessels. The retreat was especially dangerous near the marshes. Later tradition holds that some Persians, unfamiliar with the ground, stumbled into the wet terrain and drowned as they fled. The Greeks reached the shore and fought over the ships. According to Herodotus, they captured seven Persian vessels, though most of the fleet escaped. Callimachus, the Athenian polemarch who had supported the decision to fight, was killed during the fighting. The later legend of Cynegirus tells that he seized a Persian ship as it tried to escape and lost his hand before dying. The story became famous in Greek memory, but its exact details cannot be verified. The battle on the plain was over. But the danger to Athens was not. Back to Athens The Persian fleet was still largely intact. Instead of returning immediately to Asia, it sailed south around Cape Sounion toward Phaleron, the harbour area near Athens. The Persian commanders may have hoped to reach the city before the Athenian army could return. If Athens had been left undefended, the fleet could have landed troops near the city and perhaps taken it through surprise or support from the followers of Hippias. Miltiades and the Athenians understood the threat. After fighting at Marathon, much of the army marched back toward Athens at speed. Aristides and his own tribe were left behind to guard the prisoners and the captured plunder When the Persian fleet reached Phaleron, it found the Athenian army already waiting. The Persians had lost their chance. Datis and Artaphernes ordered the fleet back across the Aegean. Athens had survived. Herodotus — Histories, Book VI. Encyclopaedia Britannica — Battle of Marathon.

The Choice to Attack The first turning point was the Athenian decision not to wait. The Persians had more men, a larger fleet, and the ability to threaten Athens by land or sea. If the Athenians had remained passive, they might have allowed the Persians to choose when and where the battle would happen. Miltiades persuaded Callimachus that the Greeks should attack at Marathon. This gave the Athenians the initiative and forced the Persians to fight on a field where Greek heavy infantry could reach close combat quickly. A Stronger Greek Wing The second turning point was the Greek deployment. Miltiades knew that his army was too small to form a deep line across the whole battlefield and still prevent Persian troops from going around its flanks. He solved the problem by spreading the Greeks across a wide front, making the centre thinner and the wings stronger. It was dangerous because the centre could be driven back — and it was. But the plan gave the stronger wings the chance to defeat the Persians opposite them and turn inward. The Greek centre’s retreat was not the end of the battle. It was the moment that made the encirclement possible. Closing with the Archers The third turning point was the Greek advance across open ground. The Persian army had archers and light infantry. The longer the Greeks remained at distance, the more dangerous Persian arrows became. The Greek advance reduced that danger by forcing the fight into close quarters as quickly as possible. Once the hoplites reached the Persian line, the battle became one of shields, spears, and physical pressure. That was where Greek armour and formation mattered most. The Persian Fleet Fails to Take Athens The final turning point came after the fighting on the plain. The Persian army had lost the battle, but the fleet still had enough ships to threaten Athens. If the Persians had reached Phaleron before the Athenians returned, the victory at Marathon might have meant far less. Instead, the Athenian army marched back quickly and appeared before the Persian fleet could land. The Persians abandoned the attempt and sailed home. Marathon was therefore not secure until the Athenians had defended both the battlefield and their city. Herodotus — Histories, Book VI. Encyclopaedia Britannica — Battle of Marathon.

The Count of the Dead The Greek victory was dramatic, but the casualty figures must be treated carefully. Ancient battles rarely provide numbers that can be checked with certainty, and the main ancient source, Herodotus, does not give a total for the forces engaged. According to Herodotus, 192 Athenians were killed, along with 11 Plataeans. The Persian dead were counted at 6,400, though this figure is disputed by modern historians and may not include men who drowned in the marshes or escaped to the ships. Using the figures most commonly associated with the battle, Greek losses were about 192–200 killed, while Persian losses were about 6,400 killed. The difference reflects the way the battle unfolded: the Greeks fought in close formation, while the Persian retreat became disorganized once the centre collapsed. Among the Greek dead was Callimachus, the polemarch whose deciding vote had allowed Miltiades’ plan to go forward. Athens Remains Free The immediate result was simple: the Persian expedition had failed. Eretria had been destroyed, but Athens had not. Hippias was not restored to power, and the Persian army had returned across the Aegean without conquering the city it had come to punish. For Athens, the victory had enormous political importance. The city’s young democracy had survived its first great foreign threat. The men who fought at Marathon were citizen-soldiers, and the victory strengthened the belief that Athens could defend itself without returning to tyranny or depending on a foreign king. The battle did not end the Persian threat. Darius began planning a much larger invasion, but he died before it could begin. His son Xerxes would eventually launch the great invasion of Greece in 480 BC — check out my other battles of Thermopylae and Salamis Marathon was the first victory, not the last battle. Miltiades’ Fall Miltiades became the hero of Marathon, but his success did not protect him for long. The following year, he led an Athenian expedition against the island of Paros. The operation failed, and Miltiades returned wounded and politically exposed. He was prosecuted, fined heavily, and died soon afterward from his injuries. It was a harsh ending for the man most closely associated with Athens’ greatest victory. But it also shows something important about Athenian politics: even a celebrated commander could be held accountable by the citizens he had led. The Legend of the Runner Marathon later became linked with one of history’s most famous stories: a messenger running from the battlefield to Athens, announcing victory, and dying from exhaustion. The earliest account by Herodotus tells a different story. He says that the runner Pheidippides was sent from Athens to Sparta before the battle to ask for help — a journey of roughly 150 miles, far longer than the famous run from Marathon to Athens. The story of the battlefield runner developed later. It inspired the modern marathon race, whose traditional distance of 26.2 miles was fixed centuries after the ancient battle. The legend may not describe exactly what happened in 490 BC, but it captures the feeling Marathon came to represent: a city in danger, a desperate effort, and a victory won against overwhelming odds. A Victory with Limits Marathon was one of the most important battles in Greek history, but it should not be treated as the moment when all of Greece was saved forever. Herodotus — Histories, Book VI.

1. The First Pincer in the Record Books Marathon may contain the earliest clearly described pincer movement in Western military history. Miltiades deliberately thinned his centre and strengthened both wings so that, once the wings broke their opposite numbers, they could wheel inward and trap the Persian centre between them. Later tactical manuals would formalise this idea, but Herodotus’ account already shows the core logic: a weak centre that bends, and strong wings that turn the retreat into an encirclement. 2. The Numbers Were Probably “Too Neat” The famous casualty ratio—192 Athenians dead to 6,400 Persians—is so clean that some historians suspect ancient rounding or propaganda. The Greek figure is plausible because Athenian war dead were often recorded by name on stone, but 6,400 looks suspiciously like a multiple of 192 (roughly 33⅓ times as many), suggesting a symbolic or rhetorical touch rather than a precise headcount. The real lesson is less about exact totals and more about the scale of the shock: a small citizen army inflicting disproportionately heavy losses on a great empire. Herodotus — Histories, Book VI.
