[6] The two brothers emerged victorious from a civil war in 1726 following their murder of their father, during which conflict they had employed Maratha soldiers against their opponents.
In 1739 Bakht Singh, the lord of Nagaur, decided to force concessions from Bikaner, and called for his brother Abhai (then Raja of Marwar and Jodhpur) to assist him.

Jai Singh detected these movements and marshaled his army, allies, vassals, and every nearby Mughal garrison to invade Marwar.
[6] As described in A Comprehensive History of India (1712-1772), Bhakt singh now found that his selfish plot had kindled a national warfare which threatened the honour of his clan.
The cavalry penetration was so deep that the Rathors burst through the rear of the Jaipur army and began to raid the baggage train.
[9] The Mughal contingent of Jai's battered army began firing rockets onto the battlefield, and since Bhakt Singh could not see any enemies on the field and the direction of the artillery was covered by smoke and dust, he signaled a retreat, forcing the withdraw of the remaining Rathors.
[3] Historian Jadunath Sarkar states that according to Chahar Gulzar-i-Shujai of Harcharan Das, who was an eye-witness to the battle, exaggerated the casualties with 12,000 of Jai Singh's men killed and another 12,000 wounded.
