By 1750, the ambition of Alwar Fort had increased a lot, later on Raja Madho Singh of Jaipur had occupied Alwar Fort by paying Rupees 50 thousand as bribe to its custodian and sending 500 men. When Maharaja SurajMal heard of it, he despatched a strong force of 5,000 under Rup Ram Katari and the siege of the fort was taken up. Soon after Yuvraj Jawahar Singh Of Bharatpur also joined him. In the ensuing fight there, the Jats easily gained the day and thus wrested the fort from the Rajputs (c. 23 March 1756). The Jaipur ruler, though visibly mortified by the reverse, held back as he felt himself powerless in ejecting the Jats Of Bharatpur.
