Mbh 7.145.2

“‘After, O king, the ruler of the Sindhus had been slain by the diadem-decked Arjuna, that darkness, O bull of Bharata’s race, was withdrawn by Vasudeva. Thy sons with their followers, O king, thus came to know subsequently that the darkness, they had seen, had all been an illusion produced by Vasudeva. Even thus, O king, was thy son-in-law, the ruler of the Sindhus, having caused eight Akshauhinis to be slaughtered, himself slain by Partha of inconceivable energy. Beholding Jayadratha, the ruler of the Sindhus slain, tears of sorrow fell from the eyes of thy sons. After Jayadratha, O king, had been slain by Partha, Kesava blew his conch and that scorcher of foes, viz., the mighty-armed Arjuna also blew his; Bhimasena also, in that battle, as if for sending a message to Yudhishthira, filled the welkin with a tremendous leonine shout. Yudhishthira, the son of Dharma, hearing that tremendous shout understood that the ruler of the Sindhus had been slain by the high-souled Phalguna. With sounds of drums and other instruments he gladdened the warriors of his own army, and proceeded against the son of Bharadwaja from desire of battle. Then commenced, O king, after the sun had set, a fierce battle between Drona and the Somakas, that made the very hair stand on end. Desirous of slaying him, those mighty car-warriors after the fall of Jayadratha, fought with the son of Bharadwaja, exerting themselves to their utmost. Indeed, the Pandavas, having got the victory by slaying the ruler of the Sindhus fought with Drona, intoxicated with success. Arjuna, also, O king, having slain king Jayadratha, fought with many mighty car-warriors of thy army. Indeed, that hero decked with diadem and garlands, having accomplished his former vow, began to destroy his foes like the chief of the celestials destroying the Danavas, or the sun destroying darkness.’”
