It gives a detailed account of the Sikh movement and the sacrifices made for the liberation of Gurdwara Janamsthan Nankana Sahib (Now in West Panjab, Pakistan) from the illegal possession of Mahant Narain Dass in 1920-21. While the first contingent (Jatha) led by Bhai Lachhman Singh were killed by the hired goons of the Mahant, the second Jatha led by Kartar Singh Jhabbar was saved by the timely intervention of some eminent Sikhs and the British authorities. Finally, the control of the shrine was handed over to the Sikhs and their committee headed by S. Harbans Singh Attari. Approximately the number of those martyred in this tragic episode varied between 150-200. The incident has become a historical event in the annals of Sikh history.
