Following year Ghori came again. Prithviraj advanced with his army and sent a letter to Ghori. In this letter Ghori was asked to return as he had been defeated the previous year and was spared his life. Ghori replied that he was in India on the orders of his brother, Ghiasuddin, and that he could only retreat after he got a word from his brother. This letter was sent in the evening and after sending the letter Ghori moved his camp back a few kilometers to feign retreat. On receiving this letter and seeing Muhammad move his camp back Prithviraj assumed that Ghori was not interested in fighting. Ghori also knew that rajputs did not fight in the night and only started fighting after sun had come up. (This is an ancient Kshatriya practice e.g Mahabharata was also fought mostly in day time). Ghori treacherously attacked in the early morning hours when Prithviraj and his army were sleeping and was able to win this war
The founder of the Gahadwala line was Govindchandra Gahadwala. He was an astute ruler and ruled from Kannauj. Most of North India, including the university town of Nalanda was a part of his kingdom. He stoutly defended his kingdom from further Muslims incursions. He instituted a tax for this purpose which was called Turushka Danda (i.e. tax to fight the Turushkas or Turks). His grandson was Jaichandra Gahadwala (Rathod) who played a tragic role in Indian History.
