In 1704 Anandpur was under an extended siege by the allied forces of the Mughals and the hill chiefs. Provisions were completely exhausted and the Khalsa lived on leaves and the bark of trees. The Jats of Majha made up their mind to go home. The Guru would not let them leave unless they signed a disclaimer saying that they were no longer the Sikhs of Sri Guru Gobind Singh Ji. Out of hundreds of Sikhs, only forty put their thumb impression on the disclaimer; they were then permitted to leave Anandpur. This was during the siege of Sri Anandpur Sahib, which lasted eight months long, resulting in about 10,000 Sikh Soldiers under the 10th Master, Sri Guru Gobind Singh Ji giving a devasting defeat to the one million mughals who had invaded the holy city. Each of the Hill Rajas, except about three groups were fighting along side the Mughal Imperial Army.
