Mbh 7.20.1a

“Sanjaya said, ‘Having passed the night, that mighty car-warrior viz., Bharadwaja’s son, addressed Suyodhana, O monarch, saying, “I am thine![33] I have made arrangements for Partha’s encounter with the Samsaptaka.”[34] After Partha went out for slaying the Samsaptakas, Drona then, at the head of his troops arrayed for battle, proceeded, O chief of the Bharatas, for seizing king Yudhishthira the just. Seeing that Drona had arrayed his forces in the form of a Garuda, Yudhishthira disposed his troops in counter array in the form of a semi-circle. In the mouth of that Garuda was the mighty car-warrior Drona himself. And its head was formed by king Duryodhana, surrounded by his uterine brothers. And Kritavarman and the illustrious Kripa formed the two eyes of that Garuda. And Bhutasarman, and Kshemasarman, and the valiant Karakaksha, and the Kalingas, the Singhalas, the Easterners, the Sudras, the Abhiras, the Daserakas, the Sakas, the Yavanas, the Kamvojas, the Hangsapadas, the Surasenas, the Daradas, the Madras, and the Kalikeyas, with hundreds and thousands of elephants, steeds, cars, and foot-soldiers were stationed at its neck. And Bhurisravah, and Salya, and Somadatta, and Valhika, these heroes, surrounded by a full Akshauhini, took up their position in the right wing. And Vinda and Anuvinda of Avanti, and Sudakshina, the ruler of the Kamvojas, stationed themselves in the left wing at the head, however, of Drona’s son Aswatthaman. In the back (of that Garuda) were the Kalingas, the Amvashthas, the Magadhas, the Paundras, the Madrakas, the Gandharas, the Sakunas, the Easterners, the Mountaineers, and the Vasatis.
