207 BCE
Antiochus meets strong resistance at the frontier by the Bactrian cavalry.
Euthydemus, failing in his attempt to defend the line of the Arius (Harirud) River, had fallen back to his capital, Bactra (probably Balkh in northern Afghanistan), where he withstands a two-year siege.
Finally, Antiochus concludes a peace by which Euthydemus is to keep his kingdom while acknowledging Seleucid overlordship.
