[5] Yahya Khan's governorship over Lahore was soon challenged by his brother, Shah Nawaz, who was the governor of Multan.

[6] He appointed Kaura Mal as his diwan and recognized Adina Beg Khan as the Faujdar of the Jalandhar Doaba.

[6] Shah Nawaz used his captive brother as a bargaining tool in order to get recognition from the Delhi government.

[5][6] Shah Nawaz usurped the governorship of Lahore, appointed Kaura Mal as his diwan, and recognized Adina Beg Khan as faujdar of the Jalandhar Doaba.

[6][11] Shah Nawaz began negotiating with the Delhi government to secure its recognition of his governorship, and using his captive brother as a bargaining tool.

[13][4][1][14] J. L. Mehta estimates that Ahmad Shah had around 40,000 under his command,[15] while the Cambridge History of India, suggests he had 30,000 cavalry.

[14] Shah Nawaz sent Jalhe Khan, a Pashtun commander from Kasur, to oppose Durrani's forces.

[9] Shah Nawaz accepted his advice and told his officers, Adina Beg and Diwan Kaura Mal, not to move out against the Afghan forces and to remain in their entrenchments.

[9] Ahmad Shah was able to overpower the Qizilbash soldiers of the Mughal army and began pursuing them into their entrenchments.

[9] Mir Momin Khan, Lakhpath Rai and Surat Singh all pled with Durrani to spare the city from plunder, and paid him a ransom.

[18] Ahmad Shah accepted the ransom and ordered his officers to make sure that the Afghan soldiers would not plunder the city.

[18] Ahmad Shah stayed in Lahore for five weeks before advancing on Delhi,[18][14] but was defeated during the journey by a Mughal army at Manupur.

[19] Moin ul Mulk was then appointed as governor of Lahore,[19] and both Jalhe Khan and Lakhpath Rai were arrested.
