Bhagavad-gita As it is

BG Chapters 1 - 6

Sañjaya informed King Dhṛtarāṣṭra very tactfully that his unwise policy of deceiving the sons of Pāṇḍu and endeavoring to enthrone his own sons on the seat of the kingdom was not very laudable. The signs already clearly indicated that the whole Kuru dynasty would be killed in that great battle.

BG 1.16-18 (1972), Translation and Purport

King Yudhiṣṭhira, the son of Kuntī, blew his conchshell, the Anantavijaya, and Nakula and Sahadeva blew the Sughoṣa and Maṇipuṣpaka. That great archer the King of Kāśī, the great fighter Śikhaṇḍī, Dhṛṣṭadyumna, Virāṭa and the unconquerable Sātyaki, Drupada, the sons of Draupadī, and the others, O King, such as the son of Subhadrā, greatly armed, all blew their respective conchshells.

Sañjaya informed King Dhṛtarāṣṭra very tactfully that his unwise policy of deceiving the sons of Pāṇḍu and endeavoring to enthrone his own sons on the seat of the kingdom was not very laudable. The signs already clearly indicated that the whole Kuru dynasty would be killed in that great battle. Beginning with the grandsire, Bhīṣma, down to the grandsons like Abhimanyu and others—including kings from many states of the world—all were present there, and all were doomed. The whole catastrophe was due to King Dhṛtarāṣṭra, because he encouraged the policy followed by his sons.
