In the battle field, the Sikhs, under the command of Bhai Maan Singh Nishanchi (standard bearer), gave a befitting fight to the hill army. During the battle Bhai Maan Singh was wounded and the Khalsa flag was broken. A Sikh soldier reported the incident to Guru Sahib.At this Guru Sahib tore a farra (small piece of cloth) from his Keski (under-turban) and set it in his turban in the from of a hanging flag. Guru Sahib declared that in future Khalsa flag shall never fall or get lowered.
It will be a part of the turban of every Sikh leader. At that time some prominent Sikhs were sitting near Guru Sahib. All of them tore farras from their under-turbans and decorated them in their turbans in the form of hanging flags. Sahibzada Fateh Singh, who was just five years old at that time, also hung a farra in his turban. Since this incident the tradition of farra became a part of the turban of every Sikh leaders.
Now, this tradition is no more in practice except with the Nihangs who observe it with religious fervor.This Gurdwara is known as Dumalgarh also as it owes its name to Dumala (farra) incident of November 2,1703. GURDWARA MANJI SAHIB also called Damalgarh located close to the precincts of Takht Sri Kesgarh Sahib is dedicated to Guru Gobind Singh's sons who used this place for learn-ing and practising martial skills. The double-storey domed building of the shrine stands in the middle of a 20-metre square marble-paved compound.
