Garsyeris at once broke up his camp and followed closely on the runaways, hoping to traverse the passes and approach the city before the fugitives could rally and resolve on any measures for meeting his approach.
Upon his arriving with his army before the city,
the Selgians, placing no reliance on their allies, who had suffered equally with themselves, and thoroughly dispirited by the disaster they had met with, fell into complete dismay for themselves and their country.
Calling a public assembly, therefore, they decided to send out as commissioner one of their citizens named Logbasis, who had often entertained and had been for long on terms of intimacy with that Antiochus who lost his life in <a class="linkToPlace" target="_blank" href="/place?placename=Thrace&groupId=1030&placeId=509">Thrace</a>,
and who, when Laodice, who afterwards became the wife of Achaeus, was placed under his charge, had brought up the young lady as his own daughter and treated her with especial kindness.
The Selgians sent him therefore, thinking that he was especially suited to undertake such a mission;
but in a private interview with Garsyeris he was so far from showing a disposition to be helpful to his country, as was his duty, that on the other hand he begged Garsyeris to send for Achaeus at once, engaging to betray the city to them.
Garsyeris, eagerly catching at the proposal, sent messengers to Achaeus inviting him to come and informing him of what was doing,
while he made a truce with the Selgians and dragged on the negotiations, raising perpetual disputes and scruples on points of detail, so that Achaeus might have time to arrive and Logbasis full leisure to communicate with his friends and make preparations for the design.
