How did Themistocles persuade Xerxes to attack the Greek fleet at Salamis?

To lure the Persian fleet into the narrow straits at Salamis, the Athenian strategist Themistocles sent a false message to Xerxes. In this communication, Themistocles suggested that he was prepared to change sides and support the Persians.1

This deception successfully goaded Xerxes into ordering an all-out attack on the Greek fleet. By drawing the Persians into the confined waters of the strait, Themistocles neutralized the Persian advantage in numbers and maneuverability. In these narrow conditions, the heavier Greek ships and their armored marines were able to effectively board and destroy the Persian vessels, leading to a decisive Greek victory.231
