So he assassinated his father Rana Kumbha in the year 1468 while he was praying in the Kumbhashyam Temple in Kumbhalgarh Fort.
[2] The death by lightning account is mentioned in the late 19th century Mewar chronicle "Vir Vinod" by the court poet Kaviraj Shyamaldas, which James Tod mistook to be about the sultan of Delhi rather than Ghiyath Shah, the Sultan of Malwa Sultanate .It was Ghiyath Shah who agreed to render assistance to Udai Singh, and in return Udai Singh agreed to give his daughter in marriage to him.
Rana Udai Singh was struck with lightning, when he was returning to his camp, after completing the negotiations, and thus the entire plan fell through and no marriage took place.
His two sons Surajmal and Sahasmal, however, remained in the Malwa court and continued to press the Sultan to help them in recovering their patrimony.
Sultan Ghiyath Shah finally agreed to assist them and with his forces marched on Chittor the capital of Mewar.
