Bhagavad Gita 1.14

ततः श्वेतैर्हयैर्युक्ते महति स्यन्दने स्थितौ।माधवः पाण्डवश्चैव दिव्यौ शङ्खौ प्रदध्मतुः॥

tataḥ śvetairhayairyukte mahati syandane sthitau |mādhavaḥ pāṇḍavaścaiva divyau śaṅkhau pradadhmatuḥ ||

Then, Madhava (Krishna) and the son of Pandu (Arjuna), seated in the magnificent chariot yoked with white horses, blew divine conches.

Then, seated in their spacious war chariot, yoked with white horses, Lord Shri Krishna and Arjuna sounded their divine conch shells.

Our plain-language meaning of this verse is waiting for scholar review.
