Mbh 6.121.2b

And when in consequence of their joys thousands of trumpets, O sinless one, were blown there, we beheld O monarch, the mighty Bhimasena, the son of Kunti, sporting in great glee, having quickly slain many hostile warriors endued with great strength. And a great swoon overtook all the Kurus. And Karna and Duryodhana repeatedly drew long breaths. When the Kuru grandsire Bhishma fell down, thus, cries of sorrow were heard all round, and the greatest confusion prevailed (among the Kuru army). Beholding Bhishma fallen, thy son Dussasana, with great speed, entered the division commanded by Drona. That hero, clad in mail and at the head of his own troops, had been placed by his elder brother (for the protection of Bhishma). That tiger among men now came, plunging the troops he had commanded into grief. Beholding him coming towards them, the Kauravas surrounded prince Dussasana, desirous, O monarch, of hearing what he had to say. Then Dussasana of Kuru’s race informed Drona of Bhishma’s slaughter. Drona then, hearing those evil tidings, suddenly fell down from his car. Then the valiant son of Bharadwaja, quickly recovering his senses, forbade the Kuru army, sire, to continue the fight. Beholding the Kurus desist from battle, the Pandavas also, through messengers on fleet horses, forbade their orders, ceased to fight, the kings of both armies, putting off their armour, all repaired to Bhishma. Desisting from the fight, thousands of (other) warriors then, proceeded towards the high-souled Bhishma like the celestials towards the Lord of all creatures. Approaching Bhishma who was then, O bull of Bharata’s race, lying (on his bed of arrows), the Pandavas and the Kurus stood there, having offered him their salutations. Then Santanu’s son Bhishma of righteous soul addressed the Pandavas and the Kurus who having reverenced him thus, stood before him. And he said,--‘Welcome to you, ye highly blessed ones! Welcome to you, ye mighty car-warriors!
