Both attempts were aborted, and for the third attempt, the date of execution was fixed on last day of Poush when Ranodip Singh went on a hunting trip to Terai. The conspirating faction sought the assistance of Lieutenant Uttardhwaj who had ancestral rivalry with the Shrivikram Singh Thapa, a member of the conspirator group due to which, Lt.

All faction of Ranas knew that Jagat Jung would murder and destroy the Shamsher family if he succeeds the uncle Maharaja Ranodip Singh.
