The campaigns of 479 BC at Plataea and Mycale, the role of Pausanias, the end of the Persian invasion, the reasons for the Greek victory, and the immediate consequences for Greek leadership

A 25-mark essay needs thesis, multiple causes, counter-argument, and historiography.

Thesis

Greek unity (the Hellenic League) was necessary but not sufficient. Victory rested on hoplite warfare, naval policy, leadership, geography, and Persian limitations.

Greek unity

The Hellenic League formed at the Isthmus in autumn 481 BC. Thirty-one states joined; medising states did not. Sparta took overall command; Athens ceded naval leadership to Eurybiades. The Serpent Column at Delphi commemorates the 31 League states.

Hoplite warfare

Bronze armour, hoplon shield, long thrusting spear, and the phalanx outclassed Persian light infantry. Marathon and Plataea were close-quarters hoplite victories.

Naval policy

Themistocles built 200 triremes from the Laurion silver windfall (483/2 BC). Without the fleet there is no Salamis or Mycale.

Leadership

Themistocles at Salamis; Pausanias at Plataea; Cimon and Aristides. Persian leadership was uneven.

Geography

Narrow passes (Thermopylae), narrow straits (Salamis), and the difficulty of supplying a vast army favoured the defenders.

Persian limitations

A combined-arms force far from base; logistical strain.

Counter-argument

Unity was fragile. The League nearly broke before Salamis. After Plataea Sparta and Athens separated within five years.

Historiography

Herodotus treats unity as the moral lesson. Cawkwell (The Greek Wars, 2005) stresses Persian limitations. Holland (Persian Fire, 2005) emphasises ideology. Cartledge (After Thermopylae, 2013) re-centres Plataea.

Conclusion

Unity was necessary but acted with hoplite quality, naval policy, leadership, and Persian limitations.

A 7-mark "describe" needs forces, course, and outcome.

The forces

Around 40,000 Greek hoplites under Pausanias (regent for the young king Pleistarchus) including 5,000 Spartiates, 35,000 helots (light troops), and the Athenians under Aristides. Around 70,000 Persians and 50,000 medising Greeks (Thebans, Boeotians) under Mardonius.

The position

Both armies camped on the slopes of Mount Cithaeron in southern Boeotia for 10 days, watching each other across the Asopus river. Persian cavalry harassed Greek supply lines.

The withdrawal and engagement

Greek movement to a new water source went wrong in the night; the formation broke up. Mardonius attacked at dawn, thinking the Greeks were in flight. The Spartans and Tegeans held off the Persian and Bactrian infantry; the Athenians repulsed the Theban contingent. Mardonius was killed; his army broke.

The Persian camp

Stormed by the Athenians; vast plunder (Herodotus 9.80 to 83). 40,000 Persians under Artabazus escaped north; the rest were destroyed.

Outcome

Persian land power in Greece ended. Boeotia was punished; the Theban leadership was executed. The Serpent Column at Delphi was dedicated.

Markers reward forces, the manoeuvring phase, the engagement, and the outcome.

A 4-mark "outline" wants two clearly identified reasons, each with a developed example.

Reason 1: Naval policy. From 483/2 BC Themistocles persuaded the Athenian Assembly to spend a new silver windfall from the Laurion mines on around 200 triremes rather than distributing it to citizens. This fleet made the victories at Salamis (480 BC) and Mycale (479 BC) possible; without it Persian numbers on land alone would likely have overwhelmed the Greeks.

Reason 2: Hoplite superiority in close terrain. The bronze-armoured hoplite with the hoplon shield and doru thrusting spear, fighting in a tight phalanx, outclassed lighter-armed Persian infantry at close quarters. This decided Marathon (490 BC) and, with the ground chosen well, Plataea (479 BC).

Markers reward two distinct, developed reasons rather than a list of labels.

A 3-mark "why" needs a clear tactical explanation.

The problem

The Persian fleet (perhaps 600 to 1,200 ships by ancient counts, though modern historians such as Lazenby scale this down considerably) heavily outnumbered the roughly 370 Greek ships.

The solution

Themistocles argued for fighting in the narrow strait between Salamis and the Attic mainland, where Persian numbers could not be brought to bear and their ships, forced into a tight space, fouled each other while manoeuvring.

The result

The heavier, more manoeuvrable Greek triremes exploited the confusion to ram and disable the Persian fleet.

Markers reward the explicit link between narrow water and neutralising Persian numerical superiority.

A 6-mark "explain with a source" needs the source used explicitly, plus own knowledge developing the causal argument.

Use the source

Source A illustrates the scale of the 483/2 BC building programme: a single squadron of 20 ships already required around 4,000 rowers, showing how the roughly 200-ship fleet demanded the mobilisation of a large share of the Athenian citizen and metic population as rowers.

Own knowledge - the decision

Themistocles persuaded the Athenian Assembly to spend the Laurion silver windfall on triremes instead of a citizen distribution, overcoming opposition from those (later ostracised, such as Aristides) who preferred a hoplite-focused, land-based policy.

Own knowledge - the payoff

The fleet gave Athens the naval mass to fight at Artemisium and Salamis (480 BC) and to campaign at Mycale (479 BC), directly enabling the destruction of Persian sea power and the end of the invasion.

Markers reward explicit use of the source's detail (scale of manpower/ships), plus specific own-knowledge development of the decision and its consequences.

A 5-mark "explain" needs the mechanism linking two factors, not two separate lists.

The geography

Mainland Greece is mountainous, funnelling movement through choke points such as the pass at Thermopylae and the strait at Salamis, where Persian numerical superiority could not be deployed.

The logistics

Xerxes's army and fleet, operating perhaps 1,500 km from the Hellespont crossing point, depended on the fleet to keep the army supplied along the coast. Any check to the fleet (such as storm losses off Magnesia, or defeat at Salamis) immediately threatened the army's supply.

The combination

Because Xerxes had married a huge land force to a supply chain that only the fleet could sustain, a naval defeat at Salamis effectively forced a strategic withdrawal, since the army could not safely be provisioned so far from home once the fleet's protection was gone. Xerxes returned to Asia with the bulk of his forces after Salamis, leaving Mardonius with a smaller, more sustainable force to attempt to finish the campaign.

Markers reward the causal LINK between geography and logistics, not a description of each in isolation.

A band-6 essay for a 20-mark "evaluate the extent" needs a clear verdict, several developed argument lines each tied to evidence, engagement with the counter-view, and named historiography. This is a plan plus a model paragraph.

Thesis

Naval strategy was the necessary precondition for victory, since without the fleet Salamis and Mycale could not have happened, but it worked together with, rather than instead of, hoplite superiority on land; the two arms were complementary, and neither alone explains 480 to 479 BC.

Argument line 1: naval strategy as precondition

Themistocles's naval law of 483/2 BC converted the Laurion silver windfall into roughly 200 triremes. The decision to fight at Salamis in narrow water (480 BC) neutralised Persian numbers and destroyed Persian sea power, forcing Xerxes to withdraw the bulk of his army. Mycale (479 BC) then ended Persian naval power in the Aegean outright.

Argument line 2: hoplite superiority as the land-based decision

Marathon (490 BC) and Plataea (479 BC) were both won by the bronze-armoured hoplite phalanx at close quarters against lighter Persian infantry. Naval victory alone could not have removed Mardonius's army from Boeotia; that required the Hellenic League hoplites under Pausanias.

Argument line 3: the factors were interdependent, not competing

The Hellenic League strategy at Thermopylae/Artemisium in 480 BC deliberately paired a land chokepoint with a naval chokepoint at the same time, showing the Greeks themselves treated land and sea as one combined strategy. Persian logistical dependence on the fleet (to supply an army 1,500 km from home) meant a naval defeat had immediate land consequences.

Counter-argument

Some ancient and modern accounts privilege Salamis as THE turning point (Aeschylus's Persians centres the play on it), which risks understating Plataea's role in actually ending Persian land power in Greece a year later.

Historiography

Herodotus frames the whole war as a moral/religious triumph of Greek freedom over Persian despotism, giving weight to unity and the gods rather than to any single tactical arm. J.F. Lazenby (The Defence of Greece, 1993) is more sceptical of Herodotus's numbers and stresses hoplite quality and Greek command decisions over sheer naval genius. Peter Green (The Greco-Persian Wars, 1970) treats Themistocles's naval policy as the single most consequential strategic decision of the war, while still crediting Plataea as the campaign's true end point. Tom Holland (Persian Fire, 2005), writing for a general audience, synthesises both, presenting Salamis and Plataea as two halves of one decisive combined-arms victory.

Model paragraph (argument line 1)

The single most consequential strategic decision of the war was arguably Themistocles's persuading the Athenian Assembly, in 483/2 BC, to convert an unexpected windfall from the Laurion silver mines into a fleet of around two hundred triremes rather than a one-off citizen payout. As Peter Green argues, this single choice created the instrument that made Salamis possible the following year: fighting in the narrow strait between Salamis and the Attic mainland neutralised the Persian fleet's numerical advantage, and the resulting Greek victory forced Xerxes to withdraw the bulk of his army rather than risk it unsupplied on the far side of the Aegean. Yet the fleet's triumph on its own could not evict Mardonius's army from Boeotia; that task fell to Pausanias's hoplites at Plataea in 479 BC. Naval strategy, then, is best understood as the war's decisive enabling condition rather than its sole cause.

Conclusion

Naval strategy was necessary and arguably the single most consequential decision, but it worked in combination with hoplite quality, Greek unity, leadership and Persian logistical strain; a sustained "extent" judgement should credit the fleet as primary while not dismissing the other four factors.

Marker's note: band 6 responses commit to an explicit verdict on "the extent," use dated, specific evidence for each argument line, engage a genuine counter-view, and weave at least two named historians into the argument rather than listing them. Answers that simply describe Salamis and then describe Plataea without a comparative judgement cap at mid-band.

A band-6 essay for a 25-mark "to what extent" needs a clear verdict on the balance between Persian weakness and Greek strength, developed argument lines tied to evidence, a genuine counter-view, and named historiography. This is a plan plus a model paragraph.

Thesis

Persian strategic and logistical weakness created the conditions in which Greek victory became possible, but it did not make that victory inevitable; it required active Greek choices, naval, military, and political, to convert Persian vulnerability into actual defeat. The extent to which Persian weakness explains the outcome is therefore substantial but partial.

Argument line 1: Persian logistical strain

Xerxes's combined army and fleet, operating roughly 1,500 km from the Hellespont crossing, depended on the fleet for coastal resupply; storm losses off Magnesia in 480 BC and the naval defeat at Salamis directly threatened the army's provisioning, prompting Xerxes to withdraw most of his forces to Asia.

Argument line 2: Persian command and structural weakness

Herodotus (Histories 8 to 9) portrays disputes among Persian commanders (Artemisia's warnings against Salamis) and Mardonius's overconfidence at Plataea (attacking at dawn believing the Greeks in flight); a subject army compelled to serve under a distant king lacked the cohesion of citizen-soldiers defending their own land.

Argument line 3: Greek strength as the converting agent

None of this delivered victory automatically. Themistocles's 483/2 BC naval law, the choice to fight in the narrows at Salamis, the Hellenic League oath of 481 BC, and hoplite discipline at Plataea were active Greek decisions that exploited Persian weakness; a less capable or less unified Greek response could easily have lost despite Persian logistical strain.

Counter-argument

Some modern historians (Lazenby) push further than most in crediting Persian overreach and command error as the primary explanation, downplaying Greek unity, which Herodotus himself treats sceptically given how many poleis medised.

Historiography

Herodotus frames Persian defeat as the deserved consequence of Xerxes's hubris in bridging the Hellespont and "enslaving" the sea, a moral/religious reading. J.F. Lazenby (The Defence of Greece, 1993) gives the fullest modern case for Persian logistical and command failure as decisive. Peter Green (The Greco-Persian Wars, 1970) balances this against Themistocles's naval genius as an active Greek cause. Tom Holland (Persian Fire, 2005) synthesises both traditions for a general readership, presenting Persian overreach and Greek resourcefulness as two sides of the same story.

Model paragraph (argument line 2)

Persian command was far less unified than the scale of Xerxes's army suggested. Herodotus records the Carian queen Artemisia advising against risking a naval battle at Salamis at all, a warning Xerxes ignored; at Plataea a year later Mardonius, overconfident after ten days of stalemate, ordered a general attack at dawn believing a difficult night redeployment meant the Greeks were retreating, only to find the Spartans and Tegeans standing to fight. J.F. Lazenby reads these as symptomatic of a command structure that rewarded deference to the king over sound tactical judgement, in contrast to Greek commanders such as Themistocles and Pausanias, who could argue a case and adapt to the ground. Persian weakness, in other words, was not simply logistical but institutional.

Conclusion

Persian strategic and logistical weakness was a substantial and probably necessary condition for Greek victory, but the extent of the explanation should stop short of "sufficient": Greek naval policy, unity, and hoplite quality were the active causes that converted Persian vulnerability into actual defeat at Salamis, Plataea, and Mycale.

Marker's note: band 6 responses commit to a genuine "to what extent" verdict (substantial but partial, not simply "yes" or "no"), use precise dated evidence for both sides of the balance, and integrate at least two named historians as competing interpretive weightings rather than a list.
