It is uncertain whether the two rivals engaged in hostilities or no.

At any rate, a peace was soon made; and Seleucus, in return for five hundred elephants, ceded to Sandracottus certain lands on the west bank of the Indus, which had hitherto been regarded as Macedonian.

These probably consisted of the low grounds between the Indus and the foot of the mountains--the districts of Peshawur, Bunnoo, Murwut, Shikarpoor, and Kurrachee--which are now in British occupation.
Thus Hellenism in these parts receded more and more, the Sanskritic Indians recovering by degrees the power and independence of which they had been deprived by Alexander.
This state of things could not have been pleasing to the Greek princes of Bactria, who must have felt that the reaction towards barbarism in these parts tended to isolate them, and that there was a danger of their being crushed between the Parthians on the one hand and the perpetually advancing Indians on the other.

When Antiochus the Great, after concluding his treaty with Euthydemus, marched eastward, the Bactrian monarch probably indulged in hopes that the Indians would receive a check, and that the Greek frontier would be again carried to the Indus, if not to the Sutlej.

But, if so, he was disappointed.
