To avenge this defeat he made serious preparations and gathered an army of 1,20,000 men. He came with this large force to Lahore via Peshawar and Multan. He sent a message to Prithviraj asking him to acknowledge his supremacy and become a Muslim. Prithviraj rejected this proposal and prepared to meet the invader.
He gathered a large force consisting of 3,00,000 horses, 3000 elephants and a large body of foot soldiers. Many Hindu rajas and chieftains also joined him. In the ensuing Second Battle of Tarain in 1192, Muhammad Ghori thoroughly routed the army of Prithiviraj, who was captured and killed.
