posts, his army was otherwise ethnically diverse with soldiers also from various other ethnic and tribal groups, including non-Durrani Pashtun tribes like the Ghilji, and non-Pashtun groups such as Qizilbash, Hazaras, Tajiks, Uzbeks, and Baloch. He began his military conquest by capturing Qalati Ghilji from its governor Ashraf Tokhi and installed his own governor in Ghazni. He then wrestled Kabul and Peshawar from Mughal-appointed governor Nasir Khan, and conquered the area up to the Indus River. On 15 July 1747, Ahmad Shah appointed Muhammad Hashim Afridi as chief of the Afridi of Peshawar. Ahmad Shah conquered Herat in 1750, Balkh and Badakhshan in 1751, and Kashmir in 1752. He also made two campaigns into Khorasan (1750–51 and 1754–55). During the first campaign he besieged Mashhad in July 1750 but retreated after four months and on November 10 moved onto Nishapur. His forces suffered heavy casualties and were forced to retreat in early 1751. In 1754 he invaded again. In June 1754 he took Tun and on July 23 had besieged Mashhad. Mashhad fell on December 2 and although Shahrokh Shah was re-appointed as leader of Khorasan in May 1755 he was forced to cede Torshiz, Bakharz, Jam, Khaf, and Turbat-e Haidari to the Afghans. He invaded Nishapur again and after a 7-day siege the city fell on June 24, 1755, and was utterly destroyed. Indian invasions Early invasions Peshawar served as a convenient point for Ahmad Shah for his military conquests in Hindustan. From 1748 to 1767, he invaded Hindustan eight times. He first crossed the Indus River in 1748, the year after his ascension – his forces sacked and absorbed Lahore. In 1749, Ahmad Shah captured the area of Punjab around Lahore. In the same year, the Mughal ruler was induced to cede Sindh and all of the Punjab including the vital trans-Indus River to him, in order to save his capital from being attacked by the forces of the Durrani Empire Having thus gained substantial territories to the east without a fight, Ahmad Shah and his forces turned westward to take possession of Herat, which was ruled by Nader Shah's grandson, Shah Rukh. The city fell to the Afghans in 1750, after almost a year of siege and bloody conflict; the Afghan forces then pushed on into present-day Iran, capturing Nishapur and Mashhad in 1751. Following the recapture of Mashhad in 1754, Ahmad Shah visited the eighth Imam's
