According to official documents, Wazir Ram Singh confessed during his trial that in 1848, Maharani Jindan Kaur despatched messages to different princely states of the hills, to which Nurpur, Kangra, Jaswan, Datarpur, and Paramanand (equivalent to Hoshiarpur in Punjab) replied. In his own confession, he describes how he was asked to work with Bhai Maharaj Singh. Ram Singh met Bhai Maharaj Singh in Jhang and was given large quantities of money with instructions to wait and prepare for the battle.
