2) Siege of Anandpur Sahib May 1705 – December 1705 at Fort Anandpur Sahib, Punjab
The siege numbered one million soldiers of the Mughal Imperial Army against 10,000 Sikhs under the control of the founder of Khalsa Panth, Guru Gobind Singh Ji.
In 1705 Anandpur came 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 Sikhs 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 devastating defeat to the one million Mughals who had invaded the holy city. Each of the Hill Rajas, except about three groups, fought along side the Mughal Imperial Army.
3) Battle of Wan, 22 Singhs Vs 2,000 Mughal Troops in 1726 at Wan Tara Singh Village, Taran Taran Distt, Punjab
A government informer, Chaudhry Sahib Rai of Naushahra Pannuan, complained to the Faujdar of Patti, Jafar Begh that Tara Singh harbored criminals. The faujdar sent a contingent of 25 horse cavalry and 80 foot soldiers to Wan, but Tara Singh’s colleague Sardar met them in the fields, fought back and routed the invaders leaving several dead, including their commander, nephew of the faujdar before achieving martyrdom himself. Ja’far Begh reported the matter to Zakariya Khan, who sent a punitive expedition consisting of 2,000 horses, 5 elephants, 40 light guns, and 4 cannon wheels under orders of his deputy, Momin Khan. Tara Singh had barely 22 men with him at that time. They kept the Lahore force at bay through the night, but were killed to a man in the hand to hand fight on the following day. Their heads were taken back to Lahore and thrown in a dry well where Gurdwara Shaheed Singhania now stands in Landa Bazar. The Gurdwara Sahib now marks the site where the dead bodies of Bhai Tara Singh and his 20 companions were cremated.

4) Battle Defending Darbar Sahib in Amritsar 1764, 30 Singhs Vs 30,000 Afghans
30 Singhs Against 30,000 Afghan Force, Singhs Defended Sri Harmandir Sahib Ji till Last Breath.
Battle is often Described as a “Marriage with Death.” Jathedar Baba Gurbaksh Singh made a decision to stay at Harmandir Sahib in 1764 to defend it against a huge Afgan Force that was approaching. He led Singhs that fought valiantly against an Afghan force of 30,000. They defended Darbar Sahib, and caused heavy causalities in the Afgan Army. They are remembered as one of the most fearless Khalsa warriors of all time. He and other Singhs who stayed became shaheed martyrs for the Chardi Kala spirit of the Panth. After this Battle, the Khalsa Panth became stronger then ever. Misls joined forces which would lead to the Khalsa Raj.
These Sikhs Could have left Darbar Sahib after the decision of the Sarbatt Khalsa. Their valor is an example of the kind of Jathedars of the time who were fearless and stood against injustice.
