History of the Peloponnesian War

When, then, we had in many engagements defeated the Syracusans, against whom we were sent, and had built the walls in which we are now lying, Gylippus, the Lacedaemonian, came with an army from the Peloponnese and some of the cities in Sicily. And though in the first battle he was beaten by us, in the one fought the next day we were driven from the field by numerous cavalry and dart-men, and retired within our walls.
