Gurdwara Bhai Bir Singh Dhir Singh
Gurdwara Bhai Bir Singh Dhir Singh or Theh Sahib Bhai Bir Singh ate Dhir Singh, a small room in the vicinity of Burj Baba Deep Singh, has recently replaced a platform (thara, in Punjabi) which marked the place where two Ranghreta Sikhs, named,
Bir Singh and Dhir Singh, father and son respectively, offered themselves as targets for the Guru to test a muzzle-loading gun presented to him by a Sikh.
According to Bhai Santokh Singh, Sri Gur Pratap Suraj Granth:
Chaudhary Dalla once boasted about the loyalty and courage of his Jatt soldiers. Guru Gobind Singh asked him to provide a couple of his men as targets so that he could test the range and striking power of the new weapon. The strange demand stunned Dalla and his men out of their wits and none of them came forward.
The Guru there upon called out the two Ranghreta Sikhs who were at that moment busy tying their turbans. They came running, turbans in hand, each trying to be in front of the other in order to be the first to face the bullet. Dalla, astonished at the Sikhs spirit of sacrifice, was humbled.
