And marching his army as quickly as possible, when he came to Scythia he met with the two divisions of the Scythians together, and having fallen in with these he continued to pursue them, while they retired out of his way one day’s journey in advance: and as Darius did not cease to come after them, the Scythians according to the plan which they had made continued to retire before him towards the land of those who had refused to give their alliance, and first towards that of the Melanchlainoi; and when Scythians and Persians both together had invaded and disturbed these, the Scythians led the way to the country of the Androphagoi; and when these had also been disturbed, they proceeded to the land of the Neuroi; and while these too were being disturbed, the Scythians went on retiring before the enemy to the Agathyrsians. The Agathyrsians however, seeing that their next neighbours also were flying from the Scythians and had been disturbed, sent a herald before the Scythians invaded their land and proclaimed to the Scythians not to set foot upon their confines, warning them that if they should attempt to invade the country, they would first have to fight with them.
