Soon after this, the Spartan general Gylippus, responding to the call for help, landed at Himera. He marched towards Syracuse with 700 marines, 1,000 hoplites, 100 cavalry, and 1,000 Sicilians. They built another counter-wall on the Epipolae, but were driven back by the Athenians; in a second battle, however, Gylippus defeated the Athenians by making better use of his cavalry and javelin-throwers. The Syracusans completed their counter-wall, making the Athenian wall useless. The Corinthian fleet also arrived, under the command of Erasinides.
