Maharaja Suraj Mal displayed immense courage and carved a niche for himself in the midst of political disorder.
Gathering around him fiercely martial Jat peasants, he went from one success to another. He accompanied Emperor Muhammed Shah against Ali Muhammed Ruhela and in 1748 AD, at the battle of Bagru, he led the Jaipur vanguard against the Marathas. He also defeated the commander-in-chief of the Mughal emperor.
