Mbh 6.50.1b

During the remainder of my days I will practise the severest of ascetic austerities. I will not, O Kesava, cause these friends of mine to be slain.[353] The mighty Bhishma incessantly slays, with his celestial weapon, many thousands of my car-warriors who are foremost of smiters. Tell me, O Madhava, without delay, what should be done that might do me good. As regards Arjuna, I see that he is an indifferent spectator in this battle. Endued with great might, this Bhima alone, remembering Kshatriya duties, fighteth putting forth the prowess of his arms and to the utmost of his power. With his hero-slaying mace, this high-souled (warrior), to the full measure of his powers, achieveth the most difficult feats upon foot-soldiers and steeds and cars and elephants. This hero, however, is incapable, O sire, of destroying in fair fight the hostile host in even a century. This thy friend (Arjuna) alone (amongst) is conversant with (mighty) weapons. He, however, beholding us consumed by Bhishma and the high-souled Drona, looketh indifferently on us. The celestial weapons of Bhishma and the high-souled Drona, incessantly applied, are consuming all the Kshatriyas. O Krishna, such is his prowess, that Bhishma, with wrath excited, aided by the kings (on his side), will, without doubt annihilate us. O Lord of Yoga, look for that great bowman, that mighty car-warrior, who will give Bhishma his quietus like rain-charged clouds quenching a forest conflagration. (Then) through thy grace, O Govinda, the son of Pandu, their foes being slain, will, after recovery of their kingdom, be happy with their kinsmen.’
