Mbh 6.109.2a

Sanjaya said, “Then all those Pandavas, towards the hour of sun-rise, with beat of drums and cymbals and smaller drums, and with the blare of conches of milky whiteness, all around, went out for battle, placing Sikhandin in their van. And they marched out, O king, having formed an array that was destructive of all foes. And Sikhandin, O monarch, was stationed in the very van of all the troops. And Bhimasena and Dhananjaya became the protectors of his car-wheels. And in his rear were the sons of Draupadi and the valiant Abhimanyu. And those mighty car-warriors, viz., Satyaki and Chekitana, became the protectors of the last. And behind them was Dhrishtadyumna protected by the Panchalas. Next to Dhrishtadyumna, behind, marched the royal lord Yudhishthira, accompanied by the twins, filling the air with leonine shouts, O bull of Bharata’s race. Next behind him was Virata, surrounded by his own troops. Next to him marched Drupada, O mighty-armed one. And the five Kaikeya brothers and the valiant Dhrishtaketu, O Bharata, protected the rear of the Pandava army. Having disposed their vast army in such an array, the Pandavas rushed against thy host, prepared to cast away their lives. And similarly the Kauravas, O king, placing that mighty car-warrior Bhishma at the head of their whole host, proceeded against the Pandavas. And that invincible warrior was protected by thy mighty sons. Next behind them was the great bowman Drona, as also his mighty son (Aswatthaman). Next behind was Bhagadatta surrounded by his elephant division. And behind Bhagadatta were Kripa and Kritavarman. Behind them were Sudakshina the mighty ruler of the Kamvojas, and Jayatsena, the king of the Magadhas, and Suvala’s son and Vrihadvala. And similarly, many other kings, that were all great bowmen, protected the rear of thy host, O Bharata.
