Raged by the news of her beloved and trustworthy general, Queen Rajya Lakshmi Devi vowed to punish the culprit. She immediately ordered all the noblemen and parties for an emergency inquiry. This gathering followed one of the worstmassacres in the history of Nepal, called the Kot Massacre of September 14, 1846 that catapulted the Ranas into power. The queen suspected Kapardar Bir Keshar Pande for the killing of her secret lover and ordered Abhiman Singh Rana Magar, the then Commander-in-chief of Nepal Army, to kill the Pande leader. However having known the real culprit, he hesitated in doing so. Fighting broke out in the crowd, and he was wounded by a shot at his chest by Jung Bahadur Rana. The dying General Abhiman Singh Rana Magar, shouted, "Junge was the killer of Gagan Singh". During the free-for-all that followed, swords and knives were used on all sides. Through some scheme that has never been explained adequately, the only leader with organized bodies of troops in the kot area was Jang Bahadur, whose troops suppressed the fighting, killing many of his opponents in the process. When the struggle subsided, the courtyard was strewn with the bodies of dozens of leading nobles and an unknown number of their followers The Pande and Thapa families in particular were devastated during this slaughter. That followed a seek and destroy approach taken by Jung Bahadur Rana against all nobles in the royal house and other in the country, that included many ethnic leaders as well.
