Location of the siege of Eretria |
Thesiege of Eretria took place in 490 BC, during thefirst Persian invasion of Greece. The city ofEretria, onEuboea, was besieged by a strongPersian force under the command ofDatis andArtaphernes.
The first Persian invasion was a response to Greek involvement in theIonian Revolt, when the Eretrians andAthenians had sent a force to support the cities ofIonia in their attempt to overthrow Persian rule. The Eretrian and Athenian force had succeeded in capturing and burningSardis (the regional capital of Persia), but was then forced to retreat with heavy losses. In response to this raid, the Persian kingDarius I swore to have revenge on Athens and Eretria.
Once the Ionian revolt was finally crushed by the Persian victory at theBattle of Lade, Darius began to plan to subjugate Greece. In 490 BC, he sent a naval task force under Datis and Artaphernes across the Aegean to subjugate theCyclades, and then to make punitive attacks on Athens and Eretria. ReachingEuboea in mid-summer after a successful campaign in the Aegean, the Persians proceeded to put Eretria under siege. The siege lasted six days before afifth column of Eretrian nobles betrayed the city to the Persians. The city was plundered, and the population wasdeported to the villageArdericca in Susiana near the Persian capital.
After Eretria, the Persian force sailed for Athens, landing at the bay ofMarathon. An Athenian army marched to meet them, and won a famous victory at theBattle of Marathon, thereby ending the first Persian invasion.
The first Persian invasion of Greece had its immediate roots in theIonian Revolt, the earliest phase of theGreco-Persian Wars. However, it was also the result of the longer-term interaction between the Greeks and Persians. In 500 BC the Persian Empire was still relatively young and highly expansionistic, but prone to revolts amongst its subject peoples.[1][2][3] Moreover, the Persian king Darius was a usurper, and had spent considerable time extinguishing revolts against his rule.[1] Even before the Ionian Revolt, Darius had begun to expand the Empire into Europe, subjugatingThrace, and forcing Macedon to become a vassal of Persia.[4] Attempts at further expansion into the politically fractious world of Ancient Greece may have been inevitable.[2] However, the Ionian Revolt had directly threatened the integrity of the Persian empire, and the states of mainland Greece remained a potential menace to its future stability.[5] Darius thus resolved to subjugate and pacify Greece and the Aegean, and to punish those involved in the Ionian Revolt.[5][6]
The Ionian revolt had begun with an unsuccessfulexpedition againstNaxos, a joint venture between the Persian satrapArtaphernes and theMiletus tyrantAristagoras.[7] In the aftermath, Artaphernes decided to remove Aristagoras from power, but before he could do so, Aristagoras abdicated, and declared Miletus a democracy.[7] The otherIonian cities followed suit, ejecting their Persian-appointed tyrants, and declaring themselves democracies.[7][8] Artistagoras then appealed to the states of Mainland Greece for support, but onlyAthens andEretria offered to send troops.[9]
The reasons that Eretria sent assistance to the Ionians are not completely clear. Possibly commercial reasons were a factor; Eretria was a mercantile city, whose trade was threatened by Persian dominance of the Aegean.[9] Herodotus suggests that the Eretrians supported the revolt in order to repay the support theMilesians had given Eretria in a past war againstChalcis.[10]
The Athenians and Eretrians sent a task force of 25 triremes to Asia Minor to aid the revolt.[11] Whilst there, the Greek army surprised and outmaneuvered Artaphernes, marching to Sardis and there burning the lower city.[12] However, this was as much as the Greeks achieved, and they were then pursued back to the coast by Persian horsemen, losing many men in the process. Despite the fact their actions were ultimately fruitless, the Eretrians and in particular the Athenians had earned Darius's lasting enmity, and he vowed to punish both cities.[13] The Persian naval victory at theBattle of Lade (494 BC) all but ended the Ionian Revolt, and by 493 BC, the last hold-outs were vanquished by the Persian fleet.[14] The revolt was used as an opportunity by Darius to extend the empire's border to the islands of the East Aegean[15] and thePropontis, which had not been part of the Persian dominions before.[16] The completion of the pacification of Ionia allowed the Persians to begin planning their next moves; to extinguish the threat to the empire from Greece, and to punish Athens and Eretria.[17]
In 492 BC, once the Ionian Revolt had finally been crushed, Darius dispatched anexpedition to Greece under the command of his son-in-law,Mardonius. Mardonius re-conqueredThrace and compelledAlexander I of Macedon to makeMacedon a client kingdom to Persia, before the wrecking of his fleet brought a premature end to the campaign.[18]However, in 490 BC, following up the successes of the previous campaign, Darius decided to send a maritime expedition led byArtaphernes, (son of the satrap to whom Hippias had fled) andDatis, aMedian admiral. Mardonius had been injured in the prior campaign and had fallen out of favor. Theexpedition was intended to bring theCyclades into the Persian empire, to punishNaxos (which had resisted a Persian assault in 499 BC) and then to head to Greece to force Eretria and Athens to submit to Darius or be destroyed.[19] After island hopping across the Aegean, including successfully attacking Naxos, the Persian task force arrived off Euboea in mid summer, ready to fulfil their second major objective - to punish Eretria.
When the Eretrians had discovered that the Persian task force was heading to attack them, they had appealed to the Athenians to send reinforcements.[20] The Athenians agreed to this, and instructed the 4,000 Athenian colonists from the nearby Euboean city of Chalcis to aid the Eretrians.[20] These colonists had been planted on Chalcidian land after Athens had defeated Chalcis some 20 years previously.[21] However, when these Athenians arrived at Eretria, they were told by a leading citizen, Aeschines, of the divisions amongst the Eretrians, and he advised them to leave and save themselves.[20] The Athenians followed Aeschines' advice and sailed toOropus, thus avoiding the fate of the Eretrians.[22]
The Eretrians failed to come to a clear plan of action; in Herodotus's words "it seems that all the plans of the Eretrians were unsound; they sent to the Athenians for aid, but their counsels were divided". There were three competing plans - one group wanted to surrender to the Persians, seeking to profit thereby, others wanted to flee to the hills above Eretria, whilst others wanted to fight.[20] However, when the Persians landed in their territory, a consensus was reached not to leave the city but to try to withstand a siege, if possible.[22]
Herodotus does not estimate numbers for the Eretrians. Presumably, the majority of the citizen body would have been involved in the defence of the city, but the population of Eretria at the time cannot be clearly established.
According to Herodotus, the fleet sent by Darius consisted of 600triremes.[23] Herodotus does not estimate the size of the Persian army, only saying that they were a "large infantry that was well packed".[24] Among ancient sources, the poetSimonides, another near-contemporary, says the campaign force numbered 200,000; while a later writer, the RomanCornelius Nepos estimates 200,000 infantry and 10,000 cavalry, of which only 100,000 fought in the battle, while the rest were loaded into the fleet that was rounding Cape Sounion;[25]Plutarch[26] andPausanias[27] both independently give 300,000, as does theSuda dictionary.[28]Plato andLysias assert 500,000;[29][30] andJustinus 600,000.[31]
Modern historians have proposed wide-ranging numbers for the infantry, from 20,000–100,000 with a consensus of perhaps 25,000;[32][33][34][35] estimates for the cavalry are in the range of 1,000[32]
The Eretrian strategy was to defend their walls, and undergo a siege.[22] Possibly this was the only plan that could be agreed on, or became the default option when no plan was agreed. At any rate, since the Persian army had only suffered two defeats in the last century, and since a Greek army had never successfully fought the Persians, this was probably a sensible strategy.[36] Since the Persians arrived by ship, it is probable they had little siege equipment, and indeed, they had already been foiled in thesiege of Lindos earlier in the expedition.[37]
The Persians landed their army at three separate locations, disembarked, and advanced towards Eretria.[22] The Persians then began besieging the city.[22] Rather than passively besieging the city, the Persians seemed to have vigorously attacked the walls.[22] Herodotus reports that the fighting was fierce and both sides suffered heavy losses.[22] However, after six days of clashes, two eminent Eretrians, Euphorbus and Philagrus, opened the gates for the Persians.[22] Once inside the city, the Persians plundered it, burning temples and sanctuaries in revenge for the burning of Sardis.[22] Those citizens who were captured were enslaved, as Darius had ordered.[22]
After staying at Eretria for a few days, the Persians made their way down the coast towardsAttica.[38] The Persians dropped the captured Eretrians off on the island ofAegilia, before landing at the bay ofMarathon inAttica.[38][39] The Persians' next target was Athens. However, the Athenians had marched out from Athens to meet the Persians, and blocked the exits from the plains of Marathon.[40] After several days of stalemate, the Athenians finally resolved to attack the Persians, winning a famous victory at the ensuingBattle of Marathon.[41] After the battle, the remaining Persians fled to their ships, picked up the Eretrians fromAegilia,[41] and then sailed back toAsia Minor, thereby ending the campaign, and the first Persian invasion of Greece.[42]
When the Persian fleet arrived in Asia Minor, Datis and Artaphernes took the Eretrians before Darius inSusa.[43] The Eretrians were not harmed by Darius who decided to settle them in the town ofArdericca inCissia.[43] They were still there, using their own language and customs, when Herodotus wrote his history,[43] and were encountered byAlexander the Great during his conquest of Persia a further century later.[44]
In the meantime, Darius began raising a huge new army with which he meant to completely subjugate Greece; however, in 486 BC, hisEgyptian subjects revolted, indefinitely postponing any Greek expedition.[3] Darius then died whilst preparing to march on Egypt, and the throne of Persia passed to his sonXerxes I.[45] Xerxes crushed the Egyptian revolt, and very quickly restarted the preparations for the invasion of Greece.[46] The epicsecond Persian invasion of Greece finally began in 480 BC, and the Persians met with initial success at the battles ofThermopylae andArtemisium.[47] However, defeat at theBattle of Salamis would be the turning point in the campaign,[48] and the next year the expedition was ended by the decisive Greek victory at theBattle of Plataea.[49][50]
