Acharya: The Teacher Commands
Drona takes command of army
With Bhishma fallen on his bed of arrows, the Kaurava army desperately needs a new commander. Dronacharya, the teacher who trained both armies, accepts the burden of leadership, trapping himself between duty to his employers and love for his students. His first vow as commander will change the war's course forever.
The Tenth Night
The sun had barely set on the tenth day when Duryodhana stood before the arrow-pierced body of his grandsire. Bhishma lay on his shara-shayya, his bed of arrows, still alive, yet removed from the war forever. The invincible commander had fallen, and with him, Kaurava hopes seemed to drain into the blood-soaked earth of Kurukshetra.
Around Duryodhana, his army was breaking. Ten days of watching their greatest warrior systematically avoid killing the Pandavas had eroded morale. Now that warrior was gone, brought down by the very grandson he had protected, Arjuna firing from behind Shikhandi's shield.
"Who will lead us now?" The question passed from soldier to soldier, from chariot to tent, from the lowest foot soldier to the mightiest maharatha. "Who can stand where Bhishma stood?"
Duryodhana knew the answer. There was only one man whose reputation could match the grandsire's, only one warrior whose skill was legendary enough to rally the demoralized troops. But approaching him would require Duryodhana to confront an uncomfortable truth: he was about to ask a teacher to kill his own students.
The Reluctant Commander

Dronacharya sat alone in his tent, his weapons laid aside, his eyes fixed on something no one else could see. For ten days, he had fought with devastating effectiveness, yet always with a hollow space in his heart where joy should have been.
Every arrow I loose, I taught them to dodge. Every formation I devise, I taught them to break.
He had trained the Pandavas and Kauravas alike in his ashram at Hastinapura. Arjuna had been his finest student, the one who had absorbed not just technique but artistry, who had inherited Drona's passion for the bow. Yudhishthira had learned wisdom at his feet. Bhima had trained with his mace under Drona's watchful eye.
And Ashwatthama, his own son, fought alongside the Kauravas. His boy, his blood, his reason for living, bound to this war by Drona's own allegiance to Hastinapura.
