Mbh 7.112.3a

“Sanjaya continued, ‘Having said this much, the grandson of Sini avoided the preceptor and suddenly proceeded onwards, O king! And addressing his charioteer, he said, “Drona will, by every means, endeavour to check my progress. Proceed carefully, O Suta, in battle and listen to these grave words of mine. Yonder is seen the host of great splendour of Avantis. Next to them, is the mighty host of the Southerners. And next to it, is the great host of the Valhikas. By the side of the Valhikas, stands resolved for fight the mighty host commanded by Karna. O charioteer, all these hosts are different from one another, but relying upon one another, they protect one another on the field of battle. Arrived at the space left open between these divisions cheerfully urge thou the steeds. Indeed, O charioteer, bear me thither, making the steeds adopt a tolerable speed,--thither, that is, where are seen the Valhikas with diverse weapons uplifted in their arms, and the countless Southerners headed by the Suta’s son and whose division is seen to present a serried array of elephants and steeds and cars and in which stand foot-soldiers from various realms.” Having said this much unto his driver, avoiding the Brahmana (Drona), he proceeded, telling his charioteer, “Pass through the open space between those two divisions towards the fierce and mighty host of Karna.” Drona, however, excited with wrath, pursued him from behind, shooting at him countless shafts. Indeed, the preceptor closely followed highly blessed Yuyudhana who advanced without any desire of turning back. Smiting the great host of Karna with whetted arrows, Satyaki penetrated into the vast and limitless army of the Bharatas. When Yuyudhana, however, entered the army, the troops (opposed to him) fled away. At this, wrathful Kritavarman came forward to resist Satyaki. The valiant Satyaki striking the advancing Kritavarman with six shafts, quickly slew his four steeds with four other shafts.
