According to Herodotus, after the Persian navy began its maneuvers, Aristides arrived at the Allied camp from Aegina. Aristides had been recalled from exile along with the other ostracised Athenians on the order of Themistocles, so that Athens might be united against the Persians. Aristides told Themistocles that the Persian fleet had encircled the Allies, which greatly pleased Themistocles, as he now knew that the Persians had walked into his trap. The Allied commanders seem to have taken this news rather uncomplainingly, and Holland therefore suggests that they were party to Themistocles's ruse all along. Either way, the Allies prepared for battle, and Themistocles delivered a speech to the marines before they embarked on the ships. In the ensuing battle, the cramped conditions in the Straits hindered the much larger Persian navy, which became disarrayed, and the Allies took advantage to win a famous victory.
