Mbh 5.57.2a

“Sanjaya said, ‘I have seen Krishna, the foremost of the Andhakas and the Vrishnis, arrived there, and Chekitana, as also Satyaki, otherwise called Yuyudhana. And those two mighty car-warriors, proud of their strength and famed over all the world, have joined the Pandavas, each with a separate Akshauhini of troops. And Drupada, the king of the Panchalas, surrounded by his ten heroic sons--Satyajit and others--headed by Dhrishtadyumna, and well-protected by Sikhandin, and having furnished his soldiers with every necessary thing, hath come there with a full Akshauhini, desirous of honouring Yudhishthira. And that lord of earth, Virata, with his two sons Sankha and Uttara, as also with those heroes Suryadatta and others--headed by Madiraksha and surrounded by one Akshauhini of troops, hath thus accompanied by brothers and sons, joined the son of Pritha. And the son of Jarasandha, the king of Magadha, and Dhrishtaketu, the king of the Chedis, have separately come there, each accompanied by an Akshauhini of troops. And the five brothers of Kekaya, all having purple flags, have joined the Pandavas, surrounded by an Akshauhini of troops. Then numbering to this extent, have I seen assembled there, and these, on behalf of the Pandavas, will encounter the Dhartarashtra host. That great car-warrior, Dhrishtadyumna, who is acquainted with human, celestial, Gandharva and Asura arrays of battle, leadeth that host. O king, Bhishma, the son of Santanu, has been assigned to Sikhandin as his share; and Virata with all his Matsya warriors will support Sikhandin. The mighty king of the Madras hath been assigned to the eldest son of Pandu as his share, though some are of opinion that those two are not well-matched. Duryodhana with his sons and his ninety-nine brothers, as also the rulers of the east and the south, have been assigned to Bhimasena as his share. Karna, the son of Vikartana, and Jayadratha the king of the Sindhus, have been assigned to Arjuna as his share.
