Siraj-ud-Daulah was executed on 2 July 1757 in Murshidabad.[1] Mir Qasim, the son-in-law of Mir Jafar, tortured Lutfunnisa to discover the locations of the family jewels.[2] Soon after the killing of Siraj, all of the women of the house of his maternal grandfather, Alivardi Khan, were either poisoned or rowed out into the centre of the Hooghly river and drowned by sinking of their boat.[1] The only ones who were spared were Lutfunnisa and her daughter, who in 1758, were exiled to Dhaka and imprisoned in Jinjira Palace. She was confined there for seven years[citation needed] during which time Mir Jafar and his son each asked for her hand in marriage. She refused, stating, "having ridden an elephant before, I cannot now agree to ride an ass".[1]
