Mbh 5.48.2c

When the heroic Bhima undaunted even in situations of great danger and skilled in weapons--when that grinder of hostile hosts in battle,--mounted on his car, and alone will crush by his mace crowds of superior cars and entire ranks of infantry, seize by his nooses strong as iron, the elephants of the hostile army, and mow down the Dhritarashtra’s host, like a sturdy woodsman cutting a forest down with an axe, then will Dhritarashtra’s son repent for this war. When he will behold the Dhartarashtra’s host consumed like a hamlet full of straw-built huts by fire, or a field of ripe corn by lightning,--indeed when he will behold his vast army scattered, its leaders slain, and men running away with their back towards the field afflicted with fear, and all the warriors, humbled to the dust, being scorched by Bhimasena with the fire of his weapons,--then will the son of Dhritarashtra repent for this war. When Nakula, that warrior of wonderful feats, that foremost of all car-warriors, dexterously shooting arrows by hundreds, will mangle the car-warriors of Duryodhana, then will the son of Dhritarashtra repent for this war. Accustomed to enjoy all the comforts and luxuries of life, when Nakula, recollecting that bed of woe on which he had slept for a long time in the woods, will vomit the poison of his wrath like an angry snake, then will the son of Dhritarashtra repent for this war. Ready to lay down their very lives, the (allied) monarchs, O Suta, urged to battle by king Yudhishthira the just, will furiously advance on their resplendent cars against the (hostile) army. Beholding this, the son of Dhritarashtra will certainly have to repent. When the Kuru prince will behold the five heroic sons of (Draupadi), tender in years but not in acts, and all well-versed in arms, rush, reckless of their lives, against the Kauravas, then will that son of Dhritarashtra repent for this war.
