Much to Duryodhana’s joy, Karna entered the battlefield with Bhishma unable to continue. Drona was made the supreme commander of the Kaurava forces, according to Karna’s suggestion.Duryodhana asks Drona to capture Yudhishthira alive. It was because killing Yudhishthira in battle would only enrage the Pandavas more, whereas holding him as a hostage would be strategically useful.Drona sets up the Trigarthas to draw away Arjuna from protecting his elder brother. And formulated his battle plans for the eleventh day to this aim. He cut down Yudhishthira’s bow, which feared the Pandava army that their leader would be taken a prisoner. Thus, Arjuna rushed to the scene and with a flood of arrows and eventually defeated Drona.
