in order to defeat the Persians. Therefore, by rowing into the Straits of Salamis to attack the Greeks, the Persians were playing into the Allies' hands. It seems probable that the Persians would not have attempted this unless they had been confident of the collapse of the Allied navy, and thus Themistocles's subterfuge appears to have played a key role in tipping the balance in the favor of the Greeks. Salamis was, for the Persians, an unnecessary battle and a strategic mistake. The battle The battle of Salamis is not well described by 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. Dispositions In the Allied fleet, the Athenians were on the left, and on the right were probably the Spartans (although Diodorus says it was the Megareans and Aeginetians); the other contingents were in the center. The Allied fleet probably formed into two ranks, since the straits would have been too narrow for a single line of ships. Herodotus has the Allied fleet in a line running north–south, probably with the northern flank off the coast of modern-day Saint George's Islet (Ayios Georgis), and the southern flank off the coast of Cape Vavari (part of Salamis). Diodorus suggests the Allied fleet was aligned east–west, spanning the straits between Salamis and Mount Aigaleo; however, it is unlikely that the Allies would have rested one of their flanks against Persian occupied territory. It seems relatively certain that the Persian fleet was sent out to block the exit from the Straits the evening before the battle. Herodotus clearly believed that the Persian fleet actually entered the Straits at nightfall, planning to catch the Allies as they fled. However, modern historians have greatly debated this point, with some pointing out the difficulties of maneuvering in this confined space by night, and others accepting Herodotus's version. There are thus two possibilities; that during the night the Persians simply blocked the exit to the Straits, and then entered the straits in daylight; or that they entered the straits and positioned themselves for battle during the night. Regardless of when they attempted it, it seems likely that the Persians pivoted their fleet off the tip of Cape Vavari, so that from an initial east–west alignment
