Sanjaya said, "After the night had passed away and the sun had risen, the two armies, O king, approached each other for battle. Beholding each other, each rushed in united ranks towards the other excited with rage and desirous of vanquishing the other. And in consequence of thy evil policy, O king, the Pandavas and the Dhartarashtras thus rushed, cased in mail and forming battle-array, for striking each other. And the array that Bhishma protected from all sides, O king, was of the shape of a Makara. And so the Pandavas also, O king, protected the array they had formed (of their troops). Then thy sire Devavrata, O great king, that foremost of car-warriors, proceeded in advance, supported by a large division of cars. And others, viz., car-warriors, infantry, elephants, and cavalry, all followed him, each stationed in the place allotted. And beholding them prepared for battle, the illustrious sons of Pandu arrayed their troops in that invincible and prince of arrays called the Syena. And in the beak of that array shone Bhimasena of great strength. And in its two eyes were the invincible Sikhandin and Dhrishtadyumna of Prishata's race. And in the head was the heroic Satyaki of prowess incapable of being baffled. And in its neck was Arjuna shaking his Gandiva. And in its left wing was the high-souled and blessed Drupada with his son and supported by an akshauhini of all forces. And the king of the Kekayas, owning an akshauhini, formed the right wing (of that array).
