Histories

All these things coming together spread fear among the Argives. Therefore they resolved to defend themselves by making use of the enemies' herald, and they performed their resolve in this way: whenever the Spartan herald signalled anything to the Lacedaemonians, the Argives did the same thing.

When Cleomenes saw that the Argives did whatever was signalled by his herald, he commanded that when the herald cried the signal for breakfast, they should then put on their armor and attack the Argives.
