History of the Peloponnesian War

The Peloponnesians, therefore, charging this middle part, both drave their galleys to the dry land, and being far superior in fight, went out after them and assaulted them upon the shore.

And to help them neither was Thrasybulus able, who was in the right wing, for the multitude of the enemies that pressed him; nor Thrasyllus in the left wing, both because he could not see what was done for the promontory of Cynos-sema and because also he was kept from it by the Syracusians and others, lying upon his hands no fewer in number than themselves. Till at last the Peloponnesians, bold upon their victory, chasing some one galley some another, fell into some disorder in a part of their army.

And then those about Thrasybulus, having observed that the opposite galleys sought now no more to go beyond them, turned upon them, and fighting put them presently to flight; and having also cut off from the rest of the fleet such galleys of the Peloponnesians, of that part that had the victory, as were scattered abroad, some they assaulted, but the greatest number they put into affright unfoughten. The Syracusians also, whom those about Thrasyllus had already caused to shrink, when they saw the rest fly fled outright.
