This happened for the first time in history, when the Sikh army captured the Red Fort. When Shah Alam saw that the Sikhs had captured Diwan-i-Am, he started begging for his life. In March 1776, Baghel Singh's forces gave a crushing defeat to the Mughal army near Muzaffarnagar; thus Sikhs extended their influence on the whole of the Yamuna-Gangetic doab. Baghel Singh invaded Delhi on January 8, 1774, and captured the area up to Shahdara. The second invasion was on July 17, 1775, when the Sikhs captured the area around the present-day Pahar Ganj and Jai Singhpura. Bulk of the fighting took place where present-day New Delhi is located. Sikhs temporarily withdrew due to shortage of supplies, but they kept the agenda of the Red Fort alive, and continued domination and intrusions into the Emperor's territory surrounding Delhi. By early 1783, the Sikhs commenced preparations for the capture of the Red Fort. A force of 60,000 under the leadership of Sardar Jassa Singh Ahluwalia and Sardar Baghel Singh assembled at Ghaziabad, continuing their attacks and capturing rich towns around Delhi. Enormous booty was collected by Sikhs, which was sent to Punjab with an escort of 20,000 soldiers. One-tenth of this booty was sent to the Golden Temple as offering to the Guru.
