Explanation:

The Battle of Chamkaur Sahib, 1705 A.D. : After crossing the river Sirsa, Guru Gobind Singh Ji, some of his Sikhs and his elder sahibzadas, Ajit Singh Jujhar Singh reached Chamkaur Sahib via Ghanola and Kotla Nihang. At that time he had only forty Sikhs with him. There, they took refuge in a ‘Kachhi Garhi’. When the enemy attacked them, they resisted them valiantly. Both the Sahibzadas of Guru Sahib gave a proof of their bravery. At last they both became martyrs. While resisting the enemy valiantly, three out of the five ‘Panj Piaras- Sahib Singh, Mohkam Singh and Himmat Singh were also martyed. At Iast Guruji was left with only five out of forty Singhs. They forced Guruji to leave Chamkaur Sahib in form of Hukam urged by a Hukamnama (written or spoken letter giving some order) issued by them. Bhai Daya Singh and Bhai Dharam Singh came out of the Garhi with him. Other Singhs became martyrs while fighting.
