In July 1841, Nau Nihal #Singh's widow Sahib Kaur delivered a stillborn son.
This ended whatever hopes Chand Kaur had of realizing her claims.
But courtly intrigue had not ceased. Dhian Singh replaced the maidservants of the Dowager Maharani
with hillwomen from his own country. The latter tried to kill her by
poisoning her food and eventually finished her off on 11 June 1842,
smashing her head with wooden pikes from the kitchen (some reports
say they dropped a stone from a balcony crushing her skull.)
Maharaja Sher Singh (1807 –1843)Sher Singh was killed as he reached for a new shotgun held by Ajit Singh
Sandhawalia, who pulled the trigger. Sher Singh only had time to utter, "what treachery." https://www.sikhiwiki.org/index.php/Maharaja_Sher_Singh
