He expanded his empire, during this time Mahmud Ghori attacked India in 1191 and he was defeated at the first battle of Tarain. After defeating the army of Mahmud Ghori he was asked to attack the retreating army but in true Rajput tradition he refused to do so as it did not conform to the fair war rules. As a result Mahmud ghori again attacked India and in the second battle of Tarain Prithviraj Chauhan was defeated and captured. He was treated very badly, his eyes were burnt with red-hot irons and he was made blind. But Prithviraj did not lose courage. Helped by his court poet and friend Chand Bardai, he is believed to kill Mahmud ghori with his "shabdabhedi baan". His skill of hitting the target just on the basis of sound made by it come handy. and during the archery competition organized by Mahmud ghori, he displayed his skill. When Mahmud ghori praised him he heard his voice and attacked him. Mahmud ghori was killed. In order to escape death at the hands of enemies he and his friend Chand Bardai stabbed each other.
