There are many other heroes who are prepared to lay down their lives for my sake. All of them are well equipped with different kinds of weapons, and all are experienced in military science.
Purport by Srila Prabhupada
As far as the others are concerned -- like Jayadratha, Kritavarma and Salya -- all are determined to lay down their lives for Duryodhana's sake. In other words, it is already concluded that all of them would die in the Battle of Kurukshetra for joining the party of the sinful Duryodhana. Duryodhana was, of course, confident of his victory on account of the above-mentioned combined strength of his friends.
