In 1819 AD (Vikram 1876, Shaka 1897), due to old hostilities, the Dhanerajot Kotadia Rathores from Ninama raided Bisu and stole cows.
Jetho Singh, son of Sangram Singh, fought them and died; his headless body returned on horseback.
In fury, Rajgurani Bakhat Kanwar (of Radwa origin), wife of Khivraj Ji, performed Jammar.
As a result of her supreme sacrifice, the Dhanerajots were annihilated.
Her memorial stands by Kheemasar pond.
