According to some historians, Mu`izz al-Din directed a light cavalry of 10,000 mounted archers. They were divided into four divisions to surround the Chahamana forces from the four sides. Chahamana forces then charged Ghurid unit following which Ghurids sent a fresh cavalry unit of 12,000 and they managed to throw back the enemy.

Impacts of Battle of Tarain
Prithviraj was captured in the neighbourhood of Sursuti. Some historians believe that he was taken to Chahamana capital Ajmer, where he was made a Ghurid vassal. After sometime, Prithviraj rebelled and was killed for that. Ghurid forces started to control the entire Chahamana territory and Ghurids son Govindaraja IV was appointed on the throne of Ajmer as their vassal. Prithviraj"s younger brother Hariraja dethroned Govindaraja, and recaptured a part of his ancestral kingdom, but was later defeated by the Ghurid general Qutb al-Din Aibak. The Ghurids later defeated the king Jayachandra of Gahadavala Dynasty at the Battle of Chandawar, and they conquered most of the portions of northern India and Bengal as well.
