The two youngest sons of Guru Gobind Singh, Baba Zorawar Singh and Baba Fateh Singh were martyred at this spot on December 27, 1704. They along with the Gurus mother Mata Gujri had been captured by the governor of Sirhind Wazir Khan. Even though Islamic law does not allow for the killing of children, Wazir Khan gave the two young brothers a choice of either converting to Islam or being put to death.Both sons were bricked up in a wall and had their heads cut off but they steadfastly refused to convert to Islam. Guru Gobind Singhs mother Mata Gujri who had also been captured died from the shock of the murder of her beloved grandchildren. Five years later Banda Singh Bahadur and the Sikh army would take their revenge by destroying the town of Sirhind and killing Wazir Khan in battle.
On 11 December, they, under the orders of Waxir Khan began to be paved with bricks standing on the ground. However, as the masonry reached above chest height, it crumbled. The next day, 12 December 1705, the Sahibzadas were once again offered the choice of conversion or death. They chose the latter and fearlessly faced the executioner's sword.The cruelty of their murder and their fearlcssness of death which they preferred to giving up their faith finds a touching narration in 'GarijiShahTdari' an Urdu poem by a Muslim poet, Allahyar Khan Jogi, who used to recite it from Sikh platforms during the second and third decades of the twentieth century.
It was consequently conferred upon Bhai Buddha Singh, a pious and humble Sikh. He later sold it to Baba Ala Singh, founder of the Patiala dynasty. To honour the memory of the young martyrs, a gurdwara was constructed on the site of the old memorial and named Fatehgarh Sahib. Maharaja Karam Singh (1798-1845) of Paliala had the gurudwara rebuilt.
