meeting at Tribhuvan Khawas's house with rest of the courtiers, during which he taunted and threatened to execute Sher Bahadur. At around 10 pm, Sher Bahadur in desperation drew a sword and killed Rana Bahadur Shah before being cut down by nearby courtiers, Bam Shah and Bal Narsingh Kunwar, also allies of Bhimsen. The assassination of Rana Bahadur Shah triggered a great massacre in Bhandarkhal (a royal garden east of Kathmandu Durbar) and at the bank of Bishnumati river. That very night members of Sher Bahadur's faction – Bidur Shah, Tribhuvan Khawas, and Narsingh Gurung – and even King Prithvipal Sen of Palpa, who was under house arrest in Patan Durbar, were swiftly rounded up and killed in Bhandarkhal. Their dead bodies were not allowed funeral rites and were dragged and thrown by the banks of Bishnumati to be eaten by vultures and jackals. The next few days, all the sons of Sher Bahadur Shah, Bidur Shah, Tribhuvan Khawas and Narsingh Gurung, aged 2 to 15 were beheaded by the bank of Bishnumati; their wives and daughters were given to the untouchables, their bodyguards and servants were also put to death, and all their property seized. Bhimsen managed to kill everyone who did not agree with him or anyone who could potentially become a problem for him in the future. In this massacre that lasted for about two weeks, a total of ninety-three people (16 women and 77 men) lost their lives. Almost one and half months before the massacre, upon Bhimsen's insistence, Rana Bahadur, then 31 years old, had married a 14-year-old girl named Tripurasundari on 7 March 1806, making her his fifth legitimate wife. Taking advantage of the political chaos, Bhimsen became the Mukhtiyar (1806–37), and Tripurasundari was given the title Lalita Tripurasundari and declared regent and Queen Mother (1806–32) of Girvan Yuddha Bikram Shah, who was himself 9 years old. Thus, Bhimsen became the first person outside the royal household to hold the position of the Mukhtiyar. All the other wives (except Subarnaprabha) and concubines of Rana Bahadur, along with their handmaidens, were forced to commit sati. Bhimsen obtained a royal mandate from Tripurasundari, given in the name of King Girvan, commanding all other courtiers to be obedient to him. Bhimsen further consolidated his power by disenfranchising the old courtiers from the central power by placing them as administrators of far-flung provinces of the country. The courtiers
