'It was thus that the intelligent Kaurava arrayed his force. Between the two sides, the total number was eighteen Akshauhinis. Of this, the Pandava force consisted of seven Akshauhinis, while the Kaurava force consisted of ten Akshauhinis and one more. Five times fifty men constitute a Patti. Three Pattis make a Senamukha or Gulma. Three Gulmas make a Gana. In Duryodhana's army, there were thousands and hundred of such Ganas consisting of warriors capable of smiting (the foe) and longing for battle. And the mighty-armed king Duryodhana, selecting from among them brave and intelligent warriors, made them the leaders of his troops. And placing an Akshauhini of troops under each of those best of men, viz., Kripa, Drona, Salya, Jayadratha, the king of the Sindhus, Sudakshina the ruler of the Kamvojas, Kritavarman, Drona's son (Aswatthaman), Karna, Bhurisravas, Sakuni, the son of Suvala, and the mighty Vahlika, the king used to bring them daily before him and at all hours, and speak to them. And he repeatedly offered them worship before his very eyes. And thus appointed, all warriors, with all their followers, became desirous of doing what was most agreeable to the king.'"
