From the Pandava side comes the response. On a magnificent chariot drawn by white horses stand two figures: Krishna as the charioteer and Arjuna as the warrior. Together, they blow their divine conches.
The image is striking. White horses, a grand chariot, and on it the Lord of all creation holding the reins while the greatest archer of the age stands behind him. The verse calls their conches "divyau" (divine, celestial). These are not ordinary instruments. Krishna's conch is the Panchajanya and Arjuna's is the Devadatta. Both will be named in the very next verse.
Notice how the text contrasts the two sides. The Kaurava noise was "tumula" (a chaotic roar). Krishna and Arjuna's conches are "divya" (divine). One side has volume; the other has something beyond volume. The distinction is deliberate.
