Sangan and Behdadin were ruled by a branch of the Herat Abdalis, who had rebelled against the Safavid government 11 years prior.

Nader soon forced Hussein Sultan to submit but Kalb 'Ali and Luft 'Ali escaped and fled to Ashraf at Isfahan.

The march towards Behdadin was tough, as Astarabadi puts it: Those bandits fled precipitately from his army, which advanced, as the poet says, like a flame that consumes all before it.

He came in a few days to one of those vast deserts of land, that are so frequent in Asia ; where, mounted on a camel, with a lance in his hand, he led his soldiers without intermission, and held in common with them the toil and danger of these fatiguing marches.

However, Nader declined to pursue the Abdalis due to his insecure position, instead withdrawing with his army back to Mashhad.

[1] The expedition did not in itself provide any strategic gains as such and Nader withdrew into upper Khorasan to re-consolidate and plan an offensive against Herat.
