During the flight from Anandpur, when the Sikhs, having been promised safe passage to Punjab, Sahibzada Fateh Singh was, along with his elder brother Zorawar Singh, put under the care of his grandmother, Mata Gujari Kaur ji, Unfortunately in the confusion of the rain swollen Sarsa (normally little more than a creek) and an attack by Muslim pursuers, the Guru’s two youngest sons and their Grandmother were separated from the main body of Sikhs. However, managing to get across they were befriended by one of the Guru’s former cooks. Later betrayed and handed off by the authorities of the small village where they had been given sanctuary, they were handed over to agents of Wazir Khan and carted off to Sirhind and placed under arrest in the Khan’s Thanda Burj (cold tower). While the Thanda Burj was built to capture the cool night breezes of air drawn over water channels in the areas hot summers, during the dead of winter the unheated burj offered no comfort for the Guru’s mother and sons.
