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.

The Lacedaemonians performed this command, and when they assaulted the Argives they caught them at breakfast in obedience to the herald's signal; they killed many of them, and far more fled for refuge into the grove of Argus, which the Lacedaemonians encamped around and guarded.
