After having given this answer and crossed the Araxes, Hystaspes went to Iran [53,32] (nation), AsiaPersia to watch his son for Cyrus; and Cyrus, advancing a day's journey from the Araxes, acted according to Croesus' advice.

Cyrus and the sound portion of the Persian army marched back to the Araxes, leaving behind those that were useless; a third of the Massagetae forces attacked those of the army who were left behind and destroyed them despite resistance; then, when they had overcome their enemies, seeing the banquet spread they sat down and feasted, and after they had had their fill of food and wine, they fell asleep.

Then the Persians attacked them, killing many and taking many more alive, among whom was the son of Tomyris the queen, Spargapises by name, the leader of the Massagetae.
