In addition, he was put under pressure to bring back to the Punjab the treasure and goods his father had secreted at Haridvar. Kishan Singh, along with his mother and family, was placed under restraint at Amritsar and an official of the toshakhana was sent to Haridvar to take possession of the property. The detainees were set at liberty only after the death of Hira Singh. Kishan Singh died in the battle of Sabhraori in 1846.
