On the night of 25 April 1806, Rana Bahadur held a 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.
