BG 1.4-7: Behold in their ranks are many powerful warriors, like Yuyudhan, Virat, and Drupad, wielding mighty bows and equal in military prowess to Bheem and Arjun. There are also accomplished heroes like Dhrishtaketu, Chekitan, the gallant King of Kashi, Purujit, Kuntibhoj, and Shaibya—all the best of men. In their ranks, they also have the courageous Yudhamanyu, the gallant Uttamauja, the son of Subhadra, and the sons of Draupadi, who are all great warrior chiefs.
O best of Brahmins, hear too about the principal generals on our side, who are especially qualified to lead. These I now recount unto you
Commentary
Due to his anxiety, the Pandava army seemed much larger to Duryodhan than it actually was. He had never expected his opponents would mobilize an army of warriors with such military prowess, who would be formidable in battle. Out of fear of the looming catastrophe, he started enumerating the names of all the mahārathīs (warriors who were singly equivalent in strength to ten thousand ordinary warriors) gathered on the Pandava side. They were all exceptional heroes, and great military commanders, equivalent in valor to his cousins Arjun and Bheem.
Dronacharya was a teacher of military science and not really a warrior. However, he was on the battlefield as one of the commanders of the Kaurava army. An impudent Duryodhana even doubted the loyalty of his own preceptor. Cunning Duryodhana purposefully addressed his teacher as dwijottama (best amongst the twice-born, or Brahmins). His denigrating and vailed reminder for Dronacharya was that, if he did not display his valor in this battle, he would be considered a lowly Brahmin, who was only interested in the fine food and lavish lifestyle at the king's palace.
Then to cover up his vicious words and boost his teacher's and his own morale; Duryodhana started naming all the great generals present on the Kaurava side, describing their valor and military expertise.
