Mbh 8.12.1c

An encounter then took place between those two elephants of fierce forms resembling two huge hills topped with trees, each, fighting with the other as it liked. Those two heroes, then, whose elephants thus encountered each other, forcibly struck each other with lances endued with the splendour of solar rays, and uttered loud roars. Separating, they then careered in circles with their elephants, and each taking up a bow began to strike the other. Gladdening the people around with their loud roars and the slaps on their armpits and the whizz of the arrows, they continued to utter leonine shouts. Endued with great strength, both of them, accomplished in weapons, fought, using their elephants with upturned trunks and decked with banners floating on the wind. Then each cutting off the other's bow, they roared at each other, and rained on each other showers of darts and lances like two masses of clouds in the rainy season pouring torrents of rain. Then Kshemadhurti pierced Bhimasena in the centre of the chest with a lance endued with great impetuosity, and then with six others, and uttered a loud shout. With those lances sticking to his body, Bhimasena, whose form then blazed with wrath, looked resplendent like the cloud-covered Sun with his rays issuing through the interstices of that canopy. Then Bhima carefully hurled at his antagonist a lance bright as the rays of the Sun, coursing perfectly straight, and made entirely of iron. The ruler of the Kulutas then, drawing his bow, cut off that lance with ten shafts and then pierced the son of Pandu with sixty shafts. Then Bhima the son of Pandu, taking up a bow whose twang resembled the roar of the clouds, uttered a loud shout and deeply afflicted with his shafts the elephants of his antagonist. Thus afflicted in that battle by Bhimasena with his arrows, that elephant, though sought to be restrained, stayed not on the field like a wind-blown cloud.
