History of the Peloponnesian War

When the rest of the Athenians came up to the barrier, with the first shock of their charge they overpowered the ships stationed there, and tried to undo the fastenings; after this, as the Syracusans and allies bore down upon them from all quarters, the action spread from the barrier over the whole harbor, and was more obstinately disputed than any of the preceding ones.

On either side the rowers showed great zeal in bringing up their vessels at the boatswains' orders, and the helmsmen great skill in maneuvering, and great emulation one with another; while the ships once alongside, the soldiers on board did their best not to let the service on deck be outdone by the others;

in short, every man strove to prove himself the first in his particular department. And as many ships were engaged in a small compass (for these were the largest fleets fighting in the narrowest space ever known, being together little short of two hundred), the regular attacks with the beak were few, there being no opportunity of backing water or of breaking the line; while the collisions caused by one ship chancing to run foul of another, either in flying from or attacking a third, were more frequent.

So long as a vessel was coming up to the charge the men on the decks rained darts and arrows and stones upon her; but once alongside, the heavy infantry tried to board each other's vessel, fighting hand to hand.
