Mahabharata Bhishma Parva Chapter 120:3

Mahabharata Bhishma Parva (Bhagavat-Gita Parva) Chapter 120:3 The words spoken by the Rishis and the Vasus, however, O king, were not heard by any one save Bhishma himself. I also heard them, through the power conferred on me by the Muni. Great was the grief, O monarch, that filled the hearts of the celestials at the thought of Bhishma, that favourite of all the worlds, falling down from his car. Having listened to these words of the celestials, Santanu's son Bhishma of great ascetic merit rushed out at Vibhatsu, even though he was then being pierced with sharp arrows capable of penetrating through every armour. Then Sikhandin, O king, excited with rage, struck the grandsire of the Bharatas in the chest with nine sharp arrows. The Kuru grandsire Bhishma, however, though struck by him in battle, thus, trembled not, O monarch, but remained unmoved like a mountain during an earthquake. Then Vibhatsu, drawing his bow Gandiva with a laugh, pierced the son of Ganga with five and twenty arrows. And once more, Dhananjaya, with great speed and excited with wrath struck him in every vital part with hundreds of arrows. Thus pierced by others, also with thousands of arrows, the mighty car-warrior Bhishma pierced those others in return with great speed. And as regards the arrows shot by those warriors, Bhishma, possessed of prowess in battle that was incapable of being baffled, equally checked them all with his own straight arrows. Those arrows, however, endued with wings of gold and whetted on stone, which the mighty car-warrior Sikhandin shot in that battle, scarcely caused Bhishma any pain. Then the diadem-decked (Arjuna), excited with rage and placing Sikhandin to the fore, approached Bhishma (nearer) and once more cut off his bow. And then piercing Bhishma with ten arrows, he cut off the latter's standard with one. And striking Bhishma's chariot with ten arrows, Arjuna caused him to tremble. The son of Ganga then took up another bow that was stronger. Within, however, the twinkling of an eye, as soon, in fact, as it was taken up, Arjuna cut that bow also into three fragments with three broad-headed shafts. And thus the son of Pandu cut off in that battle even all the bows of Bhishma. After that, Bhishma the son of Santanu, no longer desired to battle with Arjuna. The latter, however, then pierced him with five and twenty arrows. That great bowman, thus pierced greatly, then addressed Dussasana, and said, 'Behold, Partha, that great car-warrior of the Pandavas, excited with wrath in battle, pierceth me alone with many thousands of arrows. He is incapable of being vanquished in battle by the wielder of the thunder-bolt himself. As regards myself also, O hero, the very gods, Danavas and Rakshasas united together, are incapable of vanquishing me. What shall I say then of mighty car-warriors among men?' While Bhishma was thus speaking to Dussasana, Phalguni with sharp shafts, and placing Sikhandin to the fore, pierced Bhishma in that battle.
