On Duryodhana's advice, Karna broke Abhimanyu's bow from behind since it was impossible to face armed Abhimanyu. Kripa killed his two chariot-drivers, and Kritavarma killed his horses; Abhimanyu took up a sword and a shield but these weapons were cut off by Drona and Ashwatthama (though in other versions of the story, the perpetrators change while the acts remain the same). Abhimanyu then took up a chariot-wheel and started fighting with it, but Kripa cut the wheel.
