History of the Peloponnesian War

The Athenians and their allies, however, put to rout the ambushing troops, slaying many of them; then, assaulting the fortification, they compelled its defenders to surrender the acropolis by agreement and march with them against Messene.

After this, on the approach of the Athenians and their allies, the Messenians also submitted, giving hostages and offering the other customary pledges of good faith.

That same summer the Athenians sent thirty ships round the Peloponnesus under the command of Demosthenes son of Alcisthenes and Procles son of Theodorus, and sixty ships and two thousand hoplites under the command of Nicias son of Niceratus, to Melos.
