|Chapter 1: Observing the Armies on the Battlefield of Kurukshetra|
bhavan bhishmas ca karnas ca
kripas ca samitim-jayah
asvatthama vikarnas ca
saumadattis tathaiva ca
There are personalities like you, Bhima, Karna, Kripa, Ashvatthama, Vikarna and the son of Somadatta called Bhurisrava, who are always victorious in battle.
Srila Prabhupada says, "Duryodhana mentioned the exceptional heroes in the battle, all of whom are ever-victorious." In mentioning the list of warriors, since both Bhisma and Drona are great warriors of similar stature, Duryodhana does not want to offend either of them by mentioning the name of the other first. He decides to name Drona first, since he is a Brahman and worthy of respect for Bhishma also. He also mentions Kripacarya and Ashvathama, the brother-in-law and son of Drona to further motivate Drona. Duryodhana also mentions Vikarna, one of his brothers, who though a powerful warrior was not in the class of the other warriors mentioned. He does so since Vikarna had objected to the disrobing of Draupadi at the dice game and Duryodhana understood that he is sympathetic to the Pandavas. Earlier, Yuyutsu, one of the half brothers of Duryodhana had defected over to the Pandavas. Now Duryodhana wanted to secure the loyalty of Vikarna by flattering him and indicating that he was depending on him. In the next verse he continues to glorify the strength of his warriors and their motivation.
