History of the Peloponnesian War

Gylippus seeing the enemy's fleet defeated and carried ashore beyond their stockades and camp, ran down to the breakwater with some of his troops, in order to cut off the men as they landed and make it easier for the Syracusans to tow off the vessels by the shore being friendly ground.

The Tyrrhenians who guarded this point for the Athenians seeing them come on in disorder, advanced out against them and attacked and routed their van, hurling it into the marsh of Lysimeleia.
