Mbh 6.121.2a

Sanjaya said,--“Slain in the evening the Kuru grandsire Bhishma saddened the Dhartarashtras and delighted the Panchalas. Falling down on the earth, he lay on his bed of arrows without however, touching the earth with his body. Indeed, when Bhishma, thrown down from his car fell upon the surface of the earth, cries of Oh and Alas were heard among all creatures. When that boundary-tree of the Kurus, viz., the ever victorious Bhishma, fell down, fear entered the hearts, O king, of the Kshatriyas of both the armies. Beholding Bhishma, the son of Santanu, with his standard overthrown and his armour cut open, both the Kurus and the Pandavas were inspired, O monarch, with sentiments of cheerlessness. And the welkin was enveloped with a gloom and the Sun himself became dim. The Earth seemed to utter loud shrieks when the son of Santanu was slain. This one is the foremost of those conversant with the Vedas! This one is the best of those that are conversant with the Vedas!--Even thus did creatures speak of that bull among men as he lay (on his bed of arrows). This one, formerly, ascertaining his sire Santanu to be afflicted by Kama, this bull among men, resolved to draw up his vital steed!--Even thus did the Rishis together with the Siddhas and the Charanas said of that foremost one of the Bharatas as he lay on his bed of arrows. When Santanu’s son Bhishma, the grandsire of the Bharatas, was slain, thy sons, O sire, knew not what to do. Their faces wore an expression of grief. The splendour of their countenances seemed to abandon them, O Bharata! All of them stood in shame, hanging down their heads. The Pandavas, on the other hand, having won the victory, stood at the head of their ranks. And they all blew their large conchs decked with gold.
