Vamsharaj Pande, once Dewan of Nepal and son of the popular commander Kalu Pande, was beheaded on the conspiracy of Queen Rajendra Laxmi with his support. In the special tribunal meeting at Bhandarkhal garden, east of Kathmandu Durbar, Swaroop Singh held Vamsharaj liable for letting the King of Parbat, Kirtibam Malla to run away in the battle a year ago. He had a fiery conversation with Vamsharaj before Vamsharaj was declared guilty and was subsequently executed by beheading on the tribunal. Historian Rishikesh Shah and Ganga Karmacharya claim that he was executed on March 1785. Bhadra Ratna Bajracharya and Tulsi Ram Vaidya claim that he was executed on 21 April 1785. On 2 July 1785, his stiff opponent Prince Regent Bahadur Shah of Nepal was arrested and on the eleventh day of imprisonment on 13 July, his only supporter Queen Rajendra Laxmi died. Then onwards, Bahadur Shah took over the regency of his nephew King Rana Bahadur Shah and on the first moments of his regency ordered Swaroop Singh who was in Pokhara to be beheaded there on the charges of treason. He had gone to Kaski to join Daljit Shah's military campaign of Kaski fearing retaliation of the old courtiers due to his conspiracy against Vamsharaj. He was executed on 24th Shrawan 1842 B.S.
