Babur began to march against him but was forced to return to Herat, due to the overwhelming superiority of the Black Sheep's armies and a plot hatched against him by 'Ala' al-Daula. Most of Persia was taken from the Timurids by 1452, with the exception of Abarquh, which was conquered by the Black Sheep in 1453. While Kirman was temporarily conquered some time later and a few attempts were made to seize Ray, Persia as a whole was never retaken by the Timurids.
