When Bhai Bidhi Chand returned Sri Guru Hargobind Sahib Ji's stolen horses, Guru Ji was at the village Kangar with Rai Jodh.

When Bidhi Chand explained that the mughal army would be in pursuit, Guru Hargobind came here to the site of Gurdwara Sri Gurusar Sahib Bhundar and met Baba Peer.

Guru Hargobind discussed the situation with Baba Peer who suggested a good place to mount a defence. The suggested place had a dense forest and good water supplies.

Guru Hargobind stayed the night at Bhundar and had a bath on following morning followed with Simran, reciting 'Satnam Waheguru'. Then Guru Ji relocated to the location of Gurdwara Sri Gurusar Sahib Mehraj and prepared a defence.

The Battle of Gurusar was the third battle fought by Sri Guru Hargobind Sahib Ji near Mehraj with Lala Beg and Qamar Beg in 1631. Despite overwhelming odds, the mughals were completely crushed in this battle.
