In 1635 Daulat Khan was appointed to the Thatta Subah with a
rank of 3000/2000, where he remained until 1640. Much of his tenure at Thatta was uneventful other than an episode in 1636 in which he arrested an imposter of the rebel Mughal prince Baisunghar and sent him to the imperial court where he was put to death. In the
20th year of
Shah Jahan's reign (1647), Daulat Khan was appointed to the governorship of Kandahar, over which Safavids had claim since the time of
Tahmasp I. Hearing of the disaster of the
Mughal army at
Balkh and Badakhshan, Shah Abbas II led an army of 40,000 to Kandahar and besieged it in December 1648. The Mughal garrison under Daulat Khan fought for one and a half months but by February defeatist attitude spread among the soldiers, who due to winter did not hope for reinforcement to arrive before spring. When Daulat Khan tried to enforce discipline it resulted in a mutiny. Ultimately, Daulat Khan surrendered the fort to Shah Abbas on 22 February, 1649. He died shortly after. ==References==
