Mbh 9.23.1e

In consequence of the surface of the Earth being covered with elephant-riders and horsemen and slain steeds and combatants with blood-stained armour and others armed with weapons and others who had sought to slay one another with diverse kinds of terrible weapons, all lying closely huddled together in that battle fraught with fearful carnage, no warrior could proceed far on his horse. Having fought for a little while, Shakuni, the son of Subala, O monarch, went away from that spot with the remnant of his cavalry numbering 6,000. Similarly, the Pandava force, covered with blood, and its animals fatigued, moved away from that spot with its remnant consisting of 6,000 horses. The blood-stained horsemen of the Pandava army then, with hearts intent on battle and prepared to lay down their lives, said, "It is no longer possible to fight here on cars; how much more difficult then to fight here on elephants! Let cars proceed against cars, and elephants against elephants! Having retreated, Shakuni is now within his own division. The royal son of Subala will not again come to battle." Then the sons of Draupadi and those infuriate elephants proceeded to the place where the Pancala prince Dhrishtadyumna, that great car-warrior, was. Sahadeva also, when that dusty cloud arose, proceeded alone to where king Yudhishthira was. After all those had gone away, Shakuni, the son of Subala, excited with wrath, once more fell upon Dhrishtadyumna's division and began to strike it. Once more a dreadful battle took place, in which the combatants were all regardless of their lives, between thy soldiers and those of the foe, all of whom were desirous of slaying one another. In that encounter of heroes, the combatants first eyed one another steadfastly, and then rushed, O king, and fell upon one another in hundreds and thousands. In that destructive carnage, heads severed with swords fell down with a noise like that of falling palmyra fruits.
