Book 4
19.1
The Lacedaemonians at once received information from deserters that Aristomenes had returned in safety. Though they thought it as incredible as the news that anyone had risen from the dead, their belief was ensured by the following action on the part of Aristomenes himself. The Corinthians were sending a force to assist the Lacedaemonians in the reduction of Eira.
19.2
Learning from his scouts that their march discipline was lax and that their encampments were made without precaution, Aristomenes attacked them by night. He slew most of them while the rest were still sleeping, and killed the leaders Hypermenides, Achladaeus, Lysistratus and Sidectus. And having plundered the generals' tent, he made it clear to the Spartans that it was Aristomenes and no other Messenian who had done this.
19.3
He also made the sacrifice called the Offering for the hundred slain to Zeus of Ithome. This was an old-established custom, all Messenians making it who had slain their hundred enemies. Aristomenes first offered it after the battle at the Boar's Tomb, his second offering was occasioned by the slaughter of the Corinthians in the night. It is said that he made a third offering as the result of his later raids.
