Battle

Salamis

480 BC

A divided coalition, a night closure, and imperial depth turned into congestion

Military history

How did Greek division lead Xerxes to commit his fleet in a strait that compressed its depth?

After Artemisium and the evacuation of Attica, the Greek fleet assembled at Salamis while Xerxes' army occupied Athens and his fleet anchored at Phalerum. The allies genuinely hesitated between staying and withdrawing toward the Isthmus. The secret message carried by Sicinnus presented this division as imminent flight; Xerxes then committed his fleet by night to close the approaches and force a decision. At dawn, confirmed encirclement compelled the Greeks to fight together. In the passage, the imperial front line remained dangerous, but ships behind it found ever less room to support, replace, or permit the leaders to retreat. Greek victory arose from this chain of decisions and constraints, not from a magical strait or an order of battle known ship by ship.

A coalition divided over the choice

Eurybiades held formal command, but Athens supplied 180 of the 378 triremes in Herodotus's catalogue. After the Acropolis fell, several Peloponnesian commanders wanted to protect the Isthmus; Athenians, Aeginetans, and Megarians preferred to remain near their territories and evacuees. Themistocles swayed the council without possessing absolute authority.

A credible opportunity for Xerxes

Sicinnus announced an enemy fleet divided and ready to flee. The message seemed plausible because it matched a real debate and promised to prevent a dispersal that would deprive Xerxes of a decisive battle. Season, supply, and the need to coordinate fleet and army also made delay costly.

Closure also commits the attacker

During the night, the imperial fleet moved to the strait's approaches and soldiers occupied Psyttaleia. The manoeuvre removed the Greeks' option of separate departure, but imposed a prolonged watch on imperial crews and placed several ranks in a space where orders, replacements, and retreats travelled poorly.

Accounts incompatible in detail

Aeschylus, Herodotus, Diodorus, and Plutarch agree on the deceptive message, night watch, and imperial defeat, but diverge on numbers, wings, guarded approaches, and the first clash. Roux and Tuplin show why no synthesis can turn these variants into one plan. The Hellenic Maritime Museum's scholarly publication confirms that palaeogeography, topography, and reconstruction remain distinct fields of research.
