The battles of Chamkaur Sahib and Khidrana were the two most important battles fought by Guru Gobind Singh Ji.

Both the battles took place during the Post Khalsa Period of Guru Gobind Singh Ji.

1. Battle of Chamkaur Sahib 1705: Guru Sahib vacated Anandpur Sahib, crossed the river Sirsa, and reached Chamkaur Sahib along with his Sikhs. There were only forty Sikhs in his party which reached Chamkaur Sahib. His two Sahibzadas, Sahibzada Ajit Singh, and Sahibzada Jujhar Singh were also with him. Guru Sahib took shelter in a mud fort of Chamkaur Sahib. The enemies followed them there and besieged the fort.

The doughty Sikhs gave them a tough fight. Both the Sahibzadas demonstrated their valor and martial qualities. They achieved martyrdom after slaying many enemy soldiers. Three Piyaras out of the five Piyaras namely, Bhai Sahib Singh, Bhai Mohkam Singh, and Bhai Himmat Singh achieved martyrdom. Guru Sahib was left with only five Sikhs. The five Sikhs requested Guru Sahib to leave the fort. Guru Sahib left the fort along with Bhai Daya Singh and Bhai Dharam Singh. The remaining Sikh followers continued to fight till they achieved martyrdom.

Guru Sahib moved towards the jungles of Machchiwara and passed through Alamgir, Dina etc. and finally reached Khidrana.

2. Battle of Khidrana 1705: Guru Sahib reached the place called Taba near Khidrana, where a large number of Sikhs had already assembled. Those forty Sikhs who had deserted Guru Sahib in the second battle of Anandpur Sahib also joined the followers of Guru Sahib at Khidrana. Mai Bhago had especially arrived to fight along with other Sikhs for Guru Sahib. It is said that nearly two thousand Sikhs had gathered there.

On the other side, with ten thousand soldiers Wazir Khan, the Subedar of Sirhind, came in pursuit of Guru Sahib. On September 29, 1705, a fierce battle was fought at Taba near Khidrana. Guru Sahib and his followers fought the battle with unbelievable courage and valour. They slew the enemy soldiers into pieces in large numbers. The Mughal soldiers started losing battle because of thirst. Finally, the remaining Mughal soldiers ran away to save their lives. Mai Bhago was badly injured and the forty Sikhs, who had signed a disclaimer (Badawa) achieved martyrdom. It was a complete victory for Guru Sahib and his Khalsa. Guru Sahib appreciated the sacrifices of the forty Sikhs and tore their disclaimer in the presence of Bhai Maha Singh. Guru Sahib prayed for their deliverance and the forty martyrs became the forty Muktas in the history of the Sikh religion. Now Khidrana is called Muktsar in their memory.
