O famous among Brahmanas (Drona), know our distinguished fighters, leading my army, as I render their names for your information.
His pointing out the heroes arrayed to fight in his army, following the list of notable leaders amidst the opponents,is a matter of mere routine. In a way, it is more for his own relief than for apprising Drona, his teacher, who knows his fighters far better than Duryodhana does.
Duryodhana’s pride and possessiveness are quite evident in referring parallelly to the leaders of his army. Though Bheeshma leads the battle as Commander-in-Chief, Duryodhana wants to convey to Drona that he himself is verily the Master of his side.
Although Bheeshma is solely in charge of the war on his side, Duryodhana feels he, as the crown prince, has the ultimate power to decide matters. The grandfather is ‘his’ Commander-in-Chief.
How subtly Sanjaya presents the dharmic (righteous) undercurrent of Kurukshetra playing on Duryodhana’s mind, leading to unrighteous behaviour!
