Being abundantly provisioned and strongly fortified, it was well able to stand a siege; and the high spirit of its inhabitants made them determined to resist to the uttermost.

While they still held out, Vardanes was called away to the East, where his brother had been gathering strength, and was once more advancing his pretensions.

The Hyrcanians, as well as the Dahse, had embraced his cause, and Parthia was threatened with dismemberment.

Vardanes, having collected his troops, occupied a position in the plain region of Bactria, and there prepared to give battle to his brother, who was likewise at the head of a considerable army.

Before, however, an engagement took place, Gotarzes discovered that there was a design among the nobles on either side to rid themselves of both the brothers, and to set up a wholly new king.
Apprehensive of the consequences, he communicated his discovery to Vardanes; and the result was that the two brothers made up their differences and agreed upon terms of peace.
