From the Kaurava side, only three warriors survived the Kurukshetra war: Kripacharya (the unarmed teacher), Ashvatthama (son of Drona, who escaped with his life), and Kritavarma (the Yadava ally). Jayadrath was killed by Arjuna to avenge Abhimanyu's death. This is well-documented in the Mahabharata.
