After meeting Duryodhana, Krishna returned to the Pandavas
and told them to prepare for war, as Duryodhana was not ready for a
settlement. A meeting of all the kings who were ready to support the
Pandavas was called. The pandavas divided their army into seven regiments. Each regiment was placed under an efficient commander. These were
Drupada, Virata, Shikhandi, Chekitana, Bhimasena, Satyaki, and
Dhristadyumna. Dhristadyumna was the commander-in-chief. On the Kaurava
side, there were warriors like Bhisma, Dronacharya, and Kripacharya.
Bhisma agreed to become the commander-in-chief on the condition that he
would not kill the Pandavas, only fight with them and that as long as he
would fight in the war, Karna would not fight.
