The Opposing Forces

The Greek fleet

Herodotus reports that there were 378 triremes in the Allied fleet, and then breaks the numbers down by city state. However, his numbers for the individual contingents only add up to 371. He does not explicitly say that all 378 fought at Salamis ("All of these came to the war providing triremes...The total number of ships...was three hundred and seventy-eight"), and he also says that the Aeginetans "had other manned ships, but they guarded their own land with these and fought at Salamis with the thirty most seaworthy". Thus it has been supposed that the difference between the numbers is accounted for a garrison of 12 ships left at Aegina. According to Herodotus, two more ships defected from the Persians to the Greeks, one before Artemisium and one before Salamis, so the total complement at Salamis would have been 373 (or 380).

According to the Athenian playwright Aeschylus, who actually fought at Salamis, the Greek fleet numbered 310 triremes (the difference being the number of Athenian ships). Ctesias claims that the Athenian fleet numbered only 110 triremes, which ties in with Aeschylus's numbers. According to Hyperides, the Greek fleet numbered only 220. The fleet was effectively under the command of Themistocles, but nominally led by the Spartan nobleman Eurybiades, as had been agreed at the congress in 481 BC. Although Themistocles had tried to claim leadership of the fleet, the other city states with navies objected, and so Sparta (which had no naval tradition) was given command of the fleet as a compromise.

The Persian fleet

According to Herodotus, the Persian fleet initially numbered 1,207 triremes. However, by his reckoning they lost approximately a third of these ships in a storm off the coast of Magnesia, 200 more in a storm off the coast of Euboea, and at least 50 ships to Allied action at the Battle of Artemisium. Herodotus claims that these losses were replaced in full, but only mentions 120 ships from the Greeks of Thrace and nearby islands as reinforcements. Aeschylus, who fought at Salamis, also claims that he faced 1,207 warships there, of which 207 were "fast ships". Diodorus and Lysias independently claim there were 1,200 ships in the Persian fleet assembled at Doriskos in the spring of 480 BC. The number of 1,207 (for the outset only) is also given by Ephorus, while his teacher Isocrates claims there were 1,300 at Doriskos and 1,200 at Salamis. Ctesias gives another number, 1,000 ships, while Plato, speaking in general terms refers to 1,000 ships and more.

The number 1,207 appears very early in the historical record (472 BC), and the Greeks appear to have genuinely believed they faced that many ships. Because of the consistency in the ancient sources, some modern historians are inclined to accept 1,207 as the size of the initial Persian fleet; others reject this number, with 1,207 being seen as more of a reference to the combined Greek fleet in the Iliad, and generally claim that the Persians could have launched no more than around 600 warships into the Aegean. However, very few appear to accept that there were this many ships at Salamis: most favour a number in the range 600-800. This is also the range given by adding the approximate number of Persian ships after Artemisium (~550) to the reinforcements (120) quantified by Herodotus.

  HISTORIC BATTLES

  Battle of Salamis (480 BC)

  Battle of Salamis was a naval battle fought between an alliance of Greek city-states under Themistocles and the Persian Empire under King Xerxes in 480 BC which resulted in a decisive victory for the outnumbered Greeks. The battle was fought in the straits between the mainland and Salamis, an island in the Saronic Gulf near Athens, and marked the high-point of the second Persian invasion of Greece.

  Sources: Some subsequent ancient historians, despite following in his footsteps, criticised Herodotus, starting with Thucydides. Nevertheless, Thucydides chose to begin his history where Herodotus left off (at the Siege of Sestos), and therefore evidently felt that Herodotus's history was accurate enough not to need re-writing or correcting.

  Background: The Greek city-states of Athens and Eretria had supported the unsuccessful Ionian Revolt against the Persian Empire of Darius I in 499-494 BC, led by the satrap of Miletus, Aristagoras. The Persian Empire was still relatively young, and prone to revolts amongst its subject peoples. Moreover, Darius was a usurper, and had spent considerable time extinguishing revolts against his rule.

  Prelude: The Allied fleet now rowed from Artemisium to Salamis to assist with the final evacuation of Athens. En route Themistocles left inscriptions addressed to the Ionian Greek crews of the Persian fleet on all springs of water that they might stop at, asking them to defect to the Allied cause. Following Thermopylae, the Persian army proceeded to burn and sack the Boeotian cities that had not surrendered, Plataea and Thespiae, before marching on the now evacuated city of Athens.

  The Opposing Forces: Herodotus reports that there were 378 triremes in the Allied fleet, and then breaks the numbers down by city state. However, his numbers for the individual contingents only add up to 371. He does not explicitly say that all 378 fought at Salamis.

  Strategic and tactical considerations: The overall Persian strategy for the invasion of 480 BC was to overwhelm the Greeks with a massive invasion force, and complete the conquest of Greece in a single campaigning season. Conversely, the Greeks sought to make the best use of their numbers by defending restricted locations and to keep the Persians in the field for as long as possible. Xerxes had obviously not anticipated such resistance, or he would have arrived earlier in the campaigning season.

  The Battle: The actual battle of Salamis is not well described by the ancient sources, and it is unlikely that anyone (other than perhaps Xerxes) involved in the battle had a clear idea what was happening across the width of the straits. What follows is more of a discussion than a definitive account.

  Aftermath: In the immediate aftermath of Salamis, Xerxes attempted to build a pontoon bridge or causeway across the straits, in order to use his army to attack the Athenians; however, with the Greek fleet now confidently patrolling the straits, this proved futile. Herodotus tells us that Xerxes held a council of war, at which the Persian general Mardonius tried to make light of the defeat.

  Significance: A significant number of historians have stated that Salamis is one of the most significant battles in human history (though the same is often stated of Marathon). In a more extreme form of this argument, some historians argue that if the Greeks had lost at Salamis, the ensuing conquest of Greece by the Persians would have effectively stifled the growth of Western Civilization as we know it. This view is based on the premise that much of modern Western society, such as philosophy, science, personal freedom and democracy are rooted in the legacy of Ancient Greece.
