As soon as Abhimanyu entered the formation, Jayadrath, the ruler of sindh blocked the other pandavas, so that abhimanyu was left alone. Jayadrath, who had been humiliated by the pandavas 5 years ago, had made severe penance and got a boon from lord shiva himself that: Jayadrath can completely hold back and counter-power, any army (except Arjuna and Krishna) for one single day of war. Inside the Chakravyuha, the trapped Abhimanyu went on a killing rampage, intending on carrying out the original strategy by himself and killing tens of thousands of Kaurava soldiers. He defeated great warriors like Drona & Kripa, who did play with full might and then, Ashwatthama, Duryodhana, Salya, Dussasana, Bhurisrava and killed many prominent heroes including Duryodhana’s son Lakshmana, Salya’s son Rukmaratha, Kritavarma’s son Matrikavata, Salya’s brother, King Brihadbala and many others.[better source needed] Karna was the last standing great warrior who could over-power abhimanyu. But since abbhimanyu was just a teenager, karna did not use his full might against him, and was fighting in an equal challenge. Finally, a strategy was formed and a joint attack on Abhimanyu followed. Karna cut off Abhimanyu’s bow and stopped his attack, 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 Ashwathama (though in other versions of the story, the perpetrators change while the acts remain the same). Abhimanyu then took up a chariot-wheel and threw it at Drona, but Kripa and Aswatthama saved Drona by cutting the wheel. With variations depending on the version of the story, Abhimanyu continues to fight, picking up discarded weapons as he requires. In one prominent ending, Abhimanyu wages war with a chariot-wheel killing hundreds of warriors; he is killed when numerous warriors simultaneously attack him from all sides after which Abhimanyu and Laxman Kumara engage into a mace fight and get unconscious at the same time. Laxman Kumara wakes early and hits Abhimanyu on his head, thus killing him. After his death, Jayadratha comes up and kicks his body apart to confirm his death, thus infuriating Abhimanyu’s father Arjuna to take a vow of either his death or Jaydratha’s.
