Saleh Khan was able to make a compromise where he would control Farah and Firuz al-Din Mirza would return into exile in Mashhad. Ever since 1816, Herat had refused to pay tribute to Persia. Kamran Shah made excuse after excuse on why he wasn't able to pay. In addition to that, Herat had actively supported the revolt of Banyad Khan Hazara (the Hazara chieftain of Jam and Bakharz). On 25 June 1821, Qajar force of 3,000 shattered Banyad Khan's Jamshidi, Hazara, and Firozkohi troops at the battle of Kariz. He was pursued into the lands of the Chahar Aimaq. In 1822, Iranian forces invaded Herat and besieged the city, aiming to restore Firuz al-Din to the throne.

When Kamran Shah returned from Qandahar, Mahmud refused to let him back in. As a result, Kamran, with the support of the Qandahar Sardars, besieged Herat. Mahmud then recruited the help of Saleh Khan, who sent Mustafa Khan Zori to break the siege of the city. They were successful, but Mustafa Khan then turned against his allies, imprisoned Saleh Khan, and forced Mahmud Shah out the city. However, Kamran and Mahmud Shah then united against Mustafa Khan and within a month deposed him. In the winter of 1824 Mustafa Khan was
