Mahabharata Drona Parva Chapter 145:7

Mahabharata Drona Parva (Jayadratha-Vadha Parva) Chapter 145:7 For grieving his foes and gladdening his friends, the son of Pandu, by shooting his shafts repeatedly at it, sent that head outside the limits of Samantapanchaka. Meanwhile, king Vriddhakshatra, the father of thy son-in-law, endued with great energy, was, O sire, engaged in his evening prayers. Decked with black locks and adorned with ear-rings, that head of Jayadratha was thrown upon Vriddhakshatra's lap, as the latter was saying his prayers in a sitting posture. Thus thrown on his lap, that head decked with car-rings, O chastiser of foes, was not seen by king Vriddhakshatra. As the latter, however, stood up after finishing his prayers it suddenly fell down on the earth. And as the head of Jayadratha fell down on the earth, the head of Vriddhakshatra, O chastiser of foes, cracked into a hundred pieces. At the sight of this, all creatures were filled with wonder. And all of them applauded Vasudeva and the mighty Vibhatsu. 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king, the ruler of the Sindhus had been slain by the diadem-decked Arjuna, that darkness, O bull of Bharata's race, was withdrawn by Vasudeva.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.
