On 16 November 1739, Nader marched his advance guard out of Peshawar heading south towards Sindh river in Punjab. Upon crossing the river the Persian army fell upon the defenceless countryside on its way to Lahor pillaging and burning as they went. The governor of Lahor began augmenting his battlements in the hope of resistance. Nader hastened his advance and attacked from an unexpected direction with such force that after a mere day had passed, the governor surrendered to the Shah's will. The gift of two million rupees to the Shah secured the governor in his position as ruler of Lahor.
