Meanwhile Logbasis had given the signal to the enemy that the moment had come, and was getting ready the soldiers collected in his house and arming himself and his sons for the coming fight.
Achaeus with half of his forces was advancing on the city itself, and Garsyeris with the rest was approaching the so‑called Cesbedium, which is a temple of Zeus and commands the city, being in the nature of a citadel.
A certain goat-herd happened to notice the movement and brought the news to the assembly, upon which some of the citizens hastened to occupy the Cesbedium and others repaired to their posts, while the larger number in their anger made for Logbasis' house.
The evidence of his treachery being now clear, some mounted the roof, and others, breaking through the front gate, massacred Logbasis, his sons, and all the rest whom they found there.
After this they proclaimed the freedom of their slaves, and dividing into separate parties, went to defend the exposed spots.
Garsyeris, now, seeing that the Cesbedium was already occupied, abandoned his attempt,
and on Achaeus trying to force an entrance through the gates, the Selgians made a sally, and after killing seven hundred of the Mysians, forced the remainder to give up the attack.
After the action Achaeus and Garsyeris withdrew to their camp, and the Selgians, afraid of civil discord among themselves and also of a siege by the enemy, sent their elders out in the guise of suppliants, and making a truce, put an end to the war on the following terms.
They were to pay at once 400 talents and to give up the Pednelissian prisoners, and they engaged to pay a further sum of 300 talents after a certain interval.
Thus the Selgians, after nearly losing their country owing to the impious treachery of Logbasis, preserved it by their own valour and disgraced neither their liberty nor their kinship with the Lacedaemonians.
