in the war of Mahabharata, the head of Bhimaputra Barbarik was installed on a high mountain by Lord Krishna. Pandavas take credit for victory after getting victory in the war. When they started arguing among themselves, Lord Krishna said that Barbarik can take the decision of victory in the war because he has seen the entire war being completed. When Barbarik was asked who got the credit for victory in the war, his answer was, “I saw Shri Krishna's Sudarshan Chakra destroying the wicked in the war and Draupadi taking the form of Mahakali and drinking the blood of all the wicked.”

Victory

 On the first day of Mahabharata war, both the armies were ready to fight. At the time Yudhishtira Maharaj got down from his chariot and entered into Kauravas army.

Then Arjuna asked Lord Krishna why he has gone to enemy's army? What is necessity of this?

Then Lord Krishna replied that,

"Inorder to seek the blessings of Bhishma deva, Guru Dronachaya, Kul guru Krupacharya and all elders, Yudhishtira has gone to them and by honoring the elders, he has already won half the Mahabharata war and now you go ahead and fight to win the remaining half."
