Mbh 6.48.2c

Ourselves, from fear of Sweta, abandoning (Bhishma) that best of car-warriors, left the battle retreating to the rear and, therefore, do we (now) behold your lordship. And all the Kurus, O son of Kuru’s race, beyond the range of arrows, and abandoning Bhishma the son of Santanu, in that battle, stood (as spectators though) armed for the combat. Cheerful in the hour of (universal) cheerlessness, that tiger among men Bhishma, alone of our army, in that terrible battle stood immovable like the mountain Meru. Taking the lives (of the foe) like the Sun at close of winter, he stood resplendent with the golden rays (of his car) like the Sun himself with his rays. And that great bowman shot clouds of arrows and struck down the Asuras.[342] And while being slaughtered by Bhishma in that dreadful combat, those warriors breaking away from their ranks, they all fled from him, as if from a fire fed by fuel.[343] Encountering the single warrior (Sweta), that slayer of foes, Bhishma, was the only one (amongst us) who was cheerful and whole. Devoted to the welfare of Duryodhana, he began to consume the Pandava (warrior). Reckless of his very life which is difficult of being cast off, and abandoning all fear he slaughtered, O king, the Pandava army in that fierce conflict.[344] And beholding the generalissimo (Sweta) smiting the (Dhartarashtra) divisions, thy father Bhishma, called also Devavrata, impetuously rushed against him. Thereupon, Sweta covered Bhishma with an extensive net-work of arrows. And Bhishma also covered Sweta with a flight of arrows. And roaring like a couple of bulls, they rushed, like two infuriate elephants of gigantic size or two raging tigers, against each other. Baffling each other’s weapons by means of their weapons, those bulls among men, viz., Bhishma and Sweta fought with each other, desirous of taking each other’s life. In one single day Bhishma, infuriate with anger, could consume the Pandava army with his arrows, if Sweta did not protect it.
