In the absence of Sher Singh, Sardar Saindha Walia and Dhyan Singh started conspiracies with the help of the British. Thereupon, Sher Singh decided to seize the throne forcibly. Rani Jindan was killed by a maid servant. A year after this event Sardar Lahana Singh and Ajit Singh Sidhanwalia,who were cousins of Ranjit Singh, killed Sher Singh and Pratap Singh and placed Daleep Singh, the youngest son of Ranjit Singh, on the throne and put a Tilak on his forehead with the blood of their fingers. Daleep Singh's mother Rani Chand Kaur, became his guardian and Hira Singh, son of Dhyan Singh, became the minister. But he was killed by the Sikh Sardars. On hearing this news, an elder brother of Daleep Singh, named Pishora Singh declared himself an independent ruler in the fort of Attock. Mantri Jawahar Singh, grandson, of last Mantri Dhyan Singh, sent Sardar Chatur Singh Attariwala, and Tiwana Sardar Fateh Khan Motiyanwala against Pishora Singh but later they joined with Pishora Singh promising him the throne of Lahore.
