Mahabharata Drona Parva Chapter 109:4

Mahabharata Drona Parva (Jayadratha-Vadha Parva) Chapter 109:4 When, returning from various tirthas, I proceeded to Dwaraka, there I witnessed thy reverence for Arjuna. While we were at Upaplavya I did not mark anybody else, O grandson of Sini, who showed us such affection as thou didst. Thou art of noble lineage and feelest reverence for us. For showing kindness, therefore, to one who is thy friend and preceptor, it behoveth thee, O thou of mighty arms, to act in a way deserving, O great bowman, of thy friendship and prowess and noble parentage and truthfulness. O thou of Madhu's race! Suyodhana, cased in armour by Drona himself, hath suddenly gone, following Arjuna! The other great car-warriors of Kauravas have, before that followed Arjuna. Loud uproars are being heard against Arjuna's car. O grandson of Sini, it behoveth thee, O giver of honours, to go thither quickly. Bhimasena and ourselves, well-equipped and with all our forces, will resist Drona if he advances against thee. Behold, O Grandson of Sini, the Bharata troops are flying away in battle, and as they are flying away, they are tittering loud wails. Like the very ocean at full tide agitated by a mighty tempest, the Dhartarashtra host, O sire, is agitated by Savyasachin. Behold, in consequence of countless cars and men and steeds moving quickly, the earthly dust raised is gradually spreading (over the field). See, that slayer of hostile hosts, Phalguna, is encompassed by the Sindhu-Sauviras, armed with spikes and lances and adorned with many horses in their ranks. Without vanquishing this force it will not be possible to vanquish Jayadratha. These warriors are prepared to lay down their lives for the sake of the ruler of the Sindhus. Behold the invincible Dhartarashtra force, stationed there, that bristles with arrows and darts and tall standards, and that teems with steeds and elephants. Hear the beat of their drums and the loud blare of their conchs, the tremendous leonine shouts uttered by them, and the rattle of their car-wheels. Hear the grunt of their elephants, the heavy tread of their foot-soldiers, and the stamping of their rushing cavalry which all seem to shake the very earth itself. Before him is the division of Jayadratha, and behind is that of Drona. So great is the number of the foes that he is capable of afflicting the chief of the celestials himself. Sunk in the midst of the fathomless host, Arjuna may lose his life.
