Mbh 8.78.2a

"Sanjaya said, 'In that afternoon, O monarch, the Suta's son of great valour began to smite all the Somakas in the very sight of Bhimasena. Bhima also of great strength began to destroy the Dhartarashtra troops. Then Karna, addressing (his driver) Shalya, said unto him, "Bear me to the Pancalas." Indeed, beholding his army in course of being routed by Bhimasena of great intelligence, Karna once more addressed his driver, saying, "Bear me to the Pancalas only." Thus urged, Shalya, the ruler of the Madras, endued with great might, urged those white steeds that were fleet as thought, towards the Cedis, the Pancalas and the Karushas. Penetrating then into that mighty host, Shalya, that grinder of hostile troops, cheerfully conducted those steeds into every spot that Karna, that foremost of warriors, desired to go to. Beholding that car cased in tiger skins and looking like a cloud, the Pandus and the Pancalas, O monarch, became terrified. The rattle then of that car, like unto the peal of thunder or the sound of a mountain splitting into fragments, became audible in that dreadful battle. With hundreds upon hundreds of keen arrows sped from the bow-string drawn to his ear, Karna then smote hundreds and thousands of warriors belonging to the Pandava army. While the unvanquished Karna was employed in achieving those feats, many mighty bowmen and great car-warriors among the Pandavas encompassed him on all sides. Indeed, Shikhandi, and Bhima, and Dhrishtadyumna, the son of Prishata, and Nakula, and Sahadeva, and the (five) sons of Draupadi, and Satyaki, surrounded the son of Radha, pouring showers of arrows upon him, from desire of despatching him to the other world. The heroic Satyaki, that best of men, struck Karna in that engagement with twenty keen shafts in the shoulder-joint.
