8.51.26

tathā senāmukhe tatra nihate pārtha pāṇḍavaiḥ |
bhīṣmaḥ prāsṛjadugrāṇi śaravarṣāṇi māriṣa || 26 ||

The van of the Kaurava army, O Partha, having been struck down by the Pandavas, Bhishma shot showers of fierce shafts, O sire! Conversant with the highest weapons, he shrouded the Cedis, the Pancalas, the Karushas, the Matsyas, and the Kaikayas with the shafts, and deprived them of life! The welkin became filled with gold-winged and straight coursing shafts, capable of piercing the bodies of all foes, that issued out of his bow. He slew thousands of car-warriors, shooting showers of shafts at a time. In all, he slew a 100,000 men and elephants of great might. Abandoning the diverse motions, each of a new kind, in which they careered, those wicked kings and elephants, while perishing, destroyed many steeds and cars and elephants. Indeed, numberless were the shafts that Bhishma shot in battle. Slaughtering the Pandava host for ten days together, Bhishma made the terraces of numberless cars empty and deprived innumerable elephants and steeds of life. Having assumed the form of Rudra or of Upendra in battle, he afflicted the Pandava divisions and caused a great carnage amongst them. Desirous of rescuing the wicked Suyodhana who was sinking in a raftless sea, he slaughtered many lords of Earth among the Cedis, the Pancalas, and the Kaikayas, and caused a great massacre of the Pandava army teeming with cars and steeds and elephants.
