Eager to defend the land that had given him refuge, Arjuna engaged the legion of Kaurava warriors. The battle starts between Arjuna and the entire Kuru army. All the warriors including Bhishma, Drona, Karna, Kripa and Ashwathama together attacked Arjuna to kill him, but Arjuna defeated all of them multiple times simultaneously. During the battle, Arjuna also killed Sangramjita, the foster brother of Karna, and instead of taking revenge for his brother, Karna fled in order to save his life from Arjuna. Karna tried to fly away from Arjuna but he could not since Arjuna invoked Sammohanaastra which made the entire army fall asleep. This is the war in which Arjuna proved that he was the best warrior in the world at his times. In this way, Arjuna alone defeated the entire Kuru army consisting of 1,000,000s of soldiers; Duryodhana, Dushyasana, Shakuni and Maharathis : Bhishma, Drona, Karna, Kripa and Ashwatthama. One of the names of Arjuna is Vijaya – ever victorious. This incident took place on the same day in which Lord Rama killed Ravana. As it was Arjuna's day, the day also became popular as "Vijaya Dashami".
