The Great Epic of the Bhārata dynasty 7.172.91

7.172.91

saṃjaya uvāca |
tasya tadvacanaṃ śrutvā droṇaputro mahārathaḥ |
namaścakāra rudrāya bahu mene ca keśavam || 91 ||

"Sanjaya continued, 'Hearing these words of Vyasa, Drona's son, that mighty car-warrior, bowed unto Rudra and regarded Kesava as worthy of the highest regards. Having his soul under complete control, he became filled with delight, the marks whereof appeared on his body. Bowing unto the great Rishi, Aswatthaman then, casting his eyes on the (Kuru) army, caused it-to be withdrawn (for nightly rest). Indeed, when, after the fall of Drona, the cheerless Kurus retired from the field, the Pandavas also, O monarch, caused their army to be withdrawn. Having fought for five days and caused an immense carnage, that Brahman well-versed in the Vedas, viz., Drona, repaired, O king, to the region of Brahma!'."
