ch. 88
7.88.1
The captains of cavalry were Harmamithres and Tithaeus, sons of Datis; the third who was captain with them, Pharnuches, had been left behind sick at Sardis. As they set forth from Sardis, an unwelcome mishap befell him: a dog ran under the feet of the horse he was riding, and the horse was taken by surprise and frightened, so it reared up and threw Pharnuches; after his fall he vomited blood and began to waste away.
7.88.2
The horse was immediately dealt with according to Pharnuces' command; his servants led it away to the place where it had thrown their master, and cut off its legs at the knee. Thus it was that Pharnuches lost his command.
