Sometime before 1191, Mu'izz ad-Din's army captured the Tabarhindah fort (probably present-day Bathinda), which was presumably under Chahamana control.[9] According to Sirhindi, sometime in 1191 (Hijri year 587), Prithviraj marched against the Ghurid army with infantry, cavalry, and an elephant force.[10] Mu'izz ad-Din was about to leave Tabarhindah, when he received the news of Prithviraj's approach; he then marched against Prithviraj, and the two armies met at Tarain.[3]
