There are many stories in the Mahabharata that no one knows about. The Mahabharata was attended by the great warriors of the world, but there were 2 great warriors in this war, which was not possible for anyone to defeat. Yes, it was necessary to remove them from the path to protect their religion, and that was the reason why they had to resort to deceit to defeat them. Yes, it is said that the name of the first great powerful warrior was Bhishma Pitamah, who was the commander of the Kauravas in the war.
Because of the promise of celibacy, they were so powerful that it was impossible for anyone in the world to defeat them. Bhishma once defeated Parashuram in the war. In order to get Bhishma Pitamah out of the way, Shri Krishna himself had to break his word and wear the Sudarshan Chakra in war. The other mighty warriors were the Kulguru Dronacharyas of the Kauravas and Pandavas.
When the Pandavas' army began to weaken in the war, Krishna deviceed half the news that an elephant called Ashwathama was killed in the war, but because of the conch shell, Dronacharya did not hear the pronunciation of the elephant and felt that his son, Ashwatthama, was killed in the war. He has been killed in the accident. As soon as the news came, Dronacharya became frustrated and began to mourn by sacrificing his weapons. He was murdered by the scene as soon as he got the chance.
