Drona Parva— The Book of Drona
The Drona Parva, the seventh book of the Mahabharata, follows the war under its second commander, the great teacher Drona — and contains some of the epic’s most heartbreaking deaths.
Drona takes command
With Bhishma fallen, Drona, master-at-arms to both Pandavas and Kauravas, becomes the Kaurava commander. He promises Duryodhana to capture Yudhishthira alive and forms vast, intricate battle arrays to trap the Pandava host.
The death of Abhimanyu
To break one such formation — the spiralling Chakravyuha — the sixteen-year-old Abhimanyu, Arjuna’s son, alone knows the way in but not the way out. He cuts deep into the enemy, but Jayadratha seals the breach behind him, and the boy is surrounded and killed by many warriors at once — a violation of the war’s code that fills his father with grief and fury.
Arjuna’s vow
Arjuna swears to slay Jayadratha before sunset or die in the flames. The Kauravas hide Jayadratha behind their whole army; as the sun seems to set, Krishna veils it with his power, and when the deceived Jayadratha shows himself in triumph, Arjuna strikes off his head. The fighting rages on into a terrible night, in which Ghatotkacha, Bhima’s demon-son, devastates the Kauravas until Karna is forced to spend on him the single infallible spear he had been saving for Arjuna.
The fall of the teacher
Drona seems unconquerable while he holds his weapons. Krishna counsels a stratagem: Bhima kills an elephant named Ashwatthama and proclaims “Ashwatthama is dead.” When the grieving Drona asks Yudhishthira — who never lies — the truthful king answers that Ashwatthama is dead, adding under his breath “the elephant.” Believing his son slain, Drona lays down his arms in despair and is beheaded by Dhrishtadyumna.
The Drona Parva shows war’s corrosion of dharma itself: even the truthful Yudhishthira bends his word, and each victory is bought with a piece of the victors’ souls.
