Mbh 8.22.1a

"Sanjaya said, 'Many elephant-warriors riding on their beasts, urged by thy son, proceeded against Dhrishtadyumna, filled with rage and desirous of compassing his destruction. Many foremost of combatants skilled in elephant-fight, belonging to the Easterners, the Southerners, the Angas, the Vangas, the Pundras, the Magadhas, the Tamraliptakas, the Mekalas, the Koshalas, the Madras, the Dasharnas, the Nishadas uniting with the Kalingas, O Bharata, and showering shafts and lances and arrows like pouring clouds, drenched the Pancala force therewith in that battle. Prishata's son covered with his arrows and shafts those (foe-crushing) elephants urged forward by their riders with heels and toes and hooks. Each of those beasts that were huge as hills, the Pancala hero pierced with ten, eight, or six whetted shafts, O Bharata. Beholding the prince of the Pancalas shrouded by those elephants like the Sun by the clouds, the Pandus and the Pancalas proceeded towards him (for his rescue) uttering loud roars and armed with sharp weapons. Pouring their weapons upon those elephants, those warriors began to dance the dance of heroes, aided by the music of their bow-strings and the sound of their palms, and urged by heroes beating the time. Then Nakula and Sahadeva, and the sons of Draupadi, and the Prabhadrakas, and Satyaki, and Shikhandi, and Chekitana endued with great energy,--all those heroes--drenched those elephants from every side with their weapons, like the clouds drenching the hills with their showers. Those furious elephants, urged on by Mleccha warriors dragging down with their trunks men and steeds and cars, crushed them with their feet. And some they pierced with the points of their tusks, and some they raised aloft and dashed down on the ground; others taken aloft on the tusks of those huge beasts, fell down inspiring spectators with fear.
