Mahabharata Bhishma Parva Chapter 116:2

Mahabharata Bhishma Parva (Bhagavat-Gita Parva) Chapter 116:2 And they made the most vigorous efforts for the overthrow of Bhishma. Then diverse kings, of great might, urged by thy son, and accompanied by Drona and his son and a large force, and the mighty Dussasana at the head of all his uterine brothers, proceeded towards Bhishma staying in the midst of that battle. Then those brave warriors of thy army, placing Bhishma of high vows in their van, battled with the Parthas headed by Sikhandin. Supported by the Chedis and the Panchalas, the ape-bannered Arjuna, placing Sikhandin ahead, proceeded towards Bhishma, the son of Santanu. And the grandson of Sini battled with Drona's son, and Dhrishtaketu with the descendant of Puru, and Yudhamanyu with thy son Duryodhana at the head of his followers. And Virata, at the head of his forces, encountered Jayadratha supported by his own troops. And Vardhakshatra's heir, O chastiser of foes, encountered thy son Chitrasena armed with excellent bow and arrows. And Yudhishthira proceeded against the mighty bowman Salya at the head of his troops. And Bhimasena, well-protected, proceeded against the elephant-division (of the Kaurava army). And Dhrishtadyumna, the prince of Panchala, excited with fury and accompanied by his brothers, proceeded against Drona, that foremost of all wielders of weapons, invincible, and irresistible. That chastiser of foes, viz., prince Vrihadvala, bearing on his standard the device of the lion, proceeded against Subhadra's son whose standard bore the device of the Karnikara flower. Thy sons, accompanied by many kings, proceeded against Sikhandin and Dhananjaya the son of Pritha, from desire of slaughtering both of them. When the combatants of both armies rushed against each other with awful prowess, the earth shook (under their tread). Beholding Santanu's son in battle, the divisions of thy army and of the foe, O Bharata, became mingled with one another. Tremendous was the din, O Bharata, that arose there of those warriors burning with rage and rushing against each other. And it was heard on all sides, O king. With the blare of conchs and the leonine shouts of the soldiers, the uproar became awful. The splendour, equal to that of either the Sun or the Moon, of bracelets and diadems of all the heroic kings, became dimmed. And the dust that rose looked like a cloud, the flash of bright weapons constituting its lightning. And the twang of bows, the whiz of arrows, the blare of conchs, the loud beat of drums, and the rattle of cars, of both the armies, constituted the fierce roar of those clouds. And the welkin, over the field of battle, in consequence of the bearded darts, the javelins, the swords and showers of arrows of both armies, was darkened. And car-warriors, and horsemen felled horsemen, in that dreadful battle. And elephants killed elephants, and foot-soldiers slew foot-soldiers. And the battle that took place there for Bhishma's sake, between the Kurus and the Pandavas, O tiger among men, was fierce in the extreme, like that between two hawks for a piece of flesh. Engaged in battle, that encounter between those combatants desirous of slaughtering and vanquishing one another, was extremely dreadful.
