According to the Greek historian Herodotus, Xerxes's first attempt to bridge the Hellespont ended in failure when a storm destroyed the flax and papyrus cables of the bridges. In retaliation, Xerxes ordered the Hellespont (the strait itself) whipped three hundred times, and had fetters thrown into the water. Xerxes's second attempt to bridge the Hellespont was successful. The Carthaginian invasion of Sicily deprived Greece of the support of the powerful monarchs of Syracuse and Agrigentum; ancient sources assume Xerxes was responsible, modern scholarship is skeptical. Many smaller Greek states, moreover, took the side of the Persians, especially Thessaly, Thebes and Argos. Xerxes was victorious during the initial battles.
