Mbh 9.12.1b

Like two gigantic elephants striking each other with their tusks, or two huge bulls striking each other with their horns, those two heroes began to strike each other with their foremost of maces, like a couple of combatants striking each other with iron bound clubs. Their limbs being struck with each other's mace, they soon became bathed in blood and looked handsomer in consequence like two flowering Kinsukas. Struck by the ruler of the Madras on both his left and right, the mighty-armed Bhimasena stood immovable like a mountain. Similarly, though struck repeatedly with the force of Bhima's mace, Shalya, O king, moved not, like a mountain assailed by an elephant with his tusks. The noise made by the blows of the maces of those two lions among men was heard on all sides like successive peals of thunder. Having ceased for a moment, those two warriors of great energy once more began, with uplifted maces, to career in closer circles. Once more the clash took place between those two warriors of superhuman feats, each having advanced towards the other by eight steps, and each assailing the other with his uplifted iron club. Then, wishing to get at each other, they once more careered in circles. Both accomplished (in the use of the mace) they began to display their superiority of skill. Uplifting their terrible weapons, they then again struck each other like mountains striking each other with their crests at the time of an earthquake. Exceedingly crushed with each other's mace in consequence of each other's strength, both those heroes fell down at the same time like a couple of poles set up for Indra's worship. The brave combatants then of both armies, at that sight, uttered cries of "Oh!" and "Alas!" Struck with great force in their vital limbs, both of them had become exceedingly agitated. Then the mighty Kripa, taking up Shalya, that bull among the Madras, on his own car, quickly bore him away from the field of battle.
