Then Dhananjaya of great valour proceeded against the car-division of the foe. The two sons of Madri and the mighty carwarrior Satyaki proceeded against Shakuni. Beholding them all flying with speed in fear of Bhimasena, Duryodhana as if smiling the while, addressed his driver, saying, "Partha, stationed there with his bow, is transgressing me. Take my steeds to the rear of the whole army. Like the ocean that cannot transgress its continents, Kunti's son Dhananjaya will never venture to transgress me, if I take up my stand in the rear. Behold, O driver, this vast host that is pursued by the Pandavas. Behold this cloud of dust that has arisen on all sides in consequence of the motion of the troops. Hear those diverse leonine roars that are so awful and loud! Therefore, O driver, proceed slowly and take up thy position in the rear. If I stay in battle and fight the Pandavas, my army, O driver, will rally and come back with vigour to battle." Hearing these words of thy son that were just those of a hero and man of honour, the driver slowly urged those steeds in trappings of gold. 21,000 foot-soldiers, deprived of elephants and steeds and car-warriors, and who were ready to lay down their lives, still stood for battle. Born in diverse countries and hailing from diverse towns, those warriors maintained their ground, desirous of winning great fame. The clash of those rushing warriors filled with joy became loud and exceedingly terrible.
