Bhīṣmadeva was certainly satisfied by seeing the triumph of virtue, and he was glad to see King Yudhiṣṭhira on the throne, although he himself fought against him. Even a great fighter like Bhīṣma could not win the Battle of Kurukṣetra because the Lord wanted to show that vice cannot conquer virtue, regardless of who tries to execute it. Bhīṣmadeva was a great devotee of the Lord, but he chose to fight against the Pāṇḍavas by the will of the Lord because the Lord wanted to show that a fighter like Bhīṣma cannot win on the wrong side.
(Srimad Bhagavatam-----1:9:16-----purport).

The attractive features of His transcendental body are desired in all the three worlds, namely the upper, middle and lower planetary systems. Nowhere in the universe are there such beautiful bodily features as those of Lord Kṛṣṇa. Therefore His transcendental body has nothing to do with anything materially created. Arjuna is described here as the conqueror, and Kṛṣṇa is described as his intimate friend. Bhīṣmadeva, on his bed of arrows after the Battle of Kurukṣetra, is remembering the particular dress of Lord Kṛṣṇa which He put on as the driver of Arjuna's chariot. While fighting was going on between Arjuna and Bhīṣma, Bhīṣma's attraction was drawn by the glittering dress of Kṛṣṇa, and indirectly he admired his so-called enemy Arjuna for possessing the Lord as his friend.
(Srimad Bhagavatam-----1:9:33-----purport).

This may be the regulation of modern democracy, but when actual monarchy was prevailing, the monarchs were not cowards elected without consideration of qualification. As it was evident from the Battlefield of Kurukṣetra, all the executive heads of both parties, like Droṇa, Bhīṣma, Arjuna and Duryodhana, were not sleeping; all of them were actual participants in the fighting, which was selected to be executed at a place away from the civil residential quarters.
(Srimad Bhagavatam-----1:9:36-----purport).

This means that the innocent citizens were immune from all effects of fighting between the rival royal parties. The citizens had no business in seeing what was going to happen during such fighting. They were to pay one fourth of their income to the ruler, whether he be Arjuna or Duryodhana. All the commanders of the parties on the Battlefield of Kurukṣetra were standing face to face, and Arjuna saw them with great compassion and lamented that he was to kill his kinsmen on the battlefield for the sake of the empire.
(Srimad Bhagavatam-----1:9:36-----purport).

The Battle of Kurukṣetra was fought on military principles but at the same time in a sporting spirit, like a friend's fight with another friend. Duryodhana criticized Bhīṣmadeva, alleging that he was reluctant to kill Arjuna because of paternal affection. A kṣatriya cannot tolerate insults on the principle of fighting.
(Srimad Bhagavatam-----1:9:37-----purport).

The dealings of Lord Kṛṣṇa and Bhīṣmadeva on the Battlefield of Kurukṣetra are interesting because the activities of Lord Śrī Kṛṣṇa appeared to be partial to Arjuna and at enmity with Bhīṣmadeva; but factually all this was especially meant to show special favor to Bhīṣmadeva, a great devotee of the Lord.
(Srimad Bhagavatam-----1:9:38-----purport).

A spiritual form like the Lord's, either two-handed or four-handed, is attained by the devotees of the Lord either in the Vaikuṇṭhas or in the Goloka planet, according to the original nature of the soul. This form, which is cent percent spiritual, is the svarūpa of the living being, and all the living beings who participated on the Battlefield of Kurukṣetra, on both sides, attained their svarūpa, as confirmed by Bhīṣmadeva. So Lord Śrī Kṛṣṇa was not merciful only to the Pāṇḍavas; He was also merciful to the other parties because all of them attained the same result.
(Srimad Bhagavatam-----1:9:39-----purport).

After gaining victory in the Battle of Kurukṣetra, Mahārāja Yudhiṣṭhira, the Emperor of the world, performed the Rājasūya sacrificial ceremony. The emperor, in those days, upon his ascendance to the throne, would send a challenge horse all over the world to declare his supremacy, and any ruling prince or king was at liberty to accept the challenge and express his tacit willingness either to obey or to disobey the supremacy of the particular emperor.
(Srimad Bhagavatam-----1:9:41-----purport).

The worshipable object of Bhīṣmadeva is Lord Śrī Kṛṣṇa as Pārtha-sārathi, and that of the gopīs is the same Kṛṣṇa in Vṛndāvana as the most attractive Śyāmasundara. Sometimes less intelligent scholars make a mistake and think that the Kṛṣṇa of Vṛndāvana and that of the Battle of Kurukṣetra are different personalities. But for Bhīṣmadeva this misconception is completely removed. Even the impersonalist's object of destination is Kṛṣṇa as the impersonal jyoti, and the yogī's destination of Paramātmā is also Kṛṣṇa.
(Srimad Bhagavatam-----1:9:42-----purport).

Dhṛtarāṣṭra and Gāndhārī, the father and the mother of Duryodhana and his brothers, were the elder uncle and aunt of Mahārāja Yudhiṣṭhira. After the Battle of Kurukṣetra, the celebrated couple, having lost all their sons and grandsons, were under the care of Mahārāja Yudhiṣṭhira. They were passing their days in great agony over such a heavy loss of life and were practically living the life of ascetics.
(Srimad Bhagavatam-----1:9:48-----purport).

Kṛṣṇa was to start for Dvārakā, His own kingdom, after the Battle of Kurukṣetra and Yudhiṣṭhira's being enthroned, but to oblige the request of Mahārāja Yudhiṣṭhira and to show special mercy to Bhīṣmadeva, Lord Kṛṣṇa stopped at Hastināpura, the capital of the Pāṇḍavas. The Lord decided to stay especially to pacify the aggrieved King as well as to please Subhadrā, sister of Lord Śrī Kṛṣṇa.
(Srimad Bhagavatam-----1:10:7-----purport).

It is due to Arjuna only that the great philosophical discourses of the Bhagavad-gītā were again spoken by the Lord on the Battlefield of Kurukṣetra. His wonderful acts on the Battlefield of Kurukṣetra are vividly described in the Mahābhārata. Arjuna was defeated, however, by his son Babhruvāhana at Maṇipura and fell unconscious when Ulūpī saved him. After the disappearance of Lord Kṛṣṇa, the message was brought by Arjuna to Mahārāja Yudhiṣṭhira.
(Srimad Bhagavatam-----1:12:21-----purport).

Draupadī was gained in this Pāñcāladeśa by Arjuna, but by order of Kuntī all five of the Pāṇḍava brothers became equally the husbands of Pāñcālī, or Draupadī. She was married with five Pāṇḍavas in the presence of Vyāsadeva. Kuntīdevī never forgot her first child, Karṇa, and after Karṇa's death in the Battle of Kurukṣetra she lamented and admitted before her other sons that Karṇa was her eldest son prior to her marriage with Mahārāja Pāṇḍu. Her prayers for the Lord after the Battle of Kurukṣetra, when Lord Kṛṣṇa was going back home, are excellently explained. Later she went to the forest with Gāndhārī for severe penance. She used to take meals after each thirty days. She finally sat down in profound meditation and later burned to ashes in a forest fire.
(Srimad Bhagavatam-----1:13:3-4-----purport).

All these different activities of Vidura within the palace politics made him well-known as partial to the Pāṇḍavas. Mahārāja Yudhiṣṭhira has referred to the past history of Vidura before his going away from home for a prolonged pilgrim's journey. Mahārāja Yudhiṣṭhira reminded him that he was equally kind and partial to his grown-up nephews, even after the Battle of Kurukṣetra, a great family disaster.
Before the Battle of Kurukṣetra, Dhṛtarāṣṭra's policy was peaceful annihilation of his nephews, and therefore he ordered Purocana to build a house at Vāraṇāvata, and when the building was finished Dhṛtarāṣṭra desired that his brother's family live there for some time. When the Pāṇḍavas were going there in the presence of all the members of the royal family, Vidura tactfully gave instructions to the Pāṇḍavas about the future plan of Dhṛtarāṣṭra.
(Srimad Bhagavatam-----1:13:8-----purport).

He thought himself ungrateful because when the Pāṇḍavas were fatherless, Mahārāja Dhṛtarāṣṭra had given them all royal facilities to live, and in return he had killed all Dhṛtarāṣṭra's sons in the Battle of Kurukṣetra. As a pious man, Mahārāja Yudhiṣṭhira took into account all his unavoidable misdeeds, and he never thought of the misdeeds of his uncle and company. Dhṛtarāṣṭra had suffered the effects of his own misdeeds by the will of the Lord, but Mahārāja Yudhiṣṭhira was thinking only of his own unavoidable misdeeds. That is the nature of a good man and devotee of the Lord. A devotee never finds fault with others, but tries to find his own and thus rectify them as far as possible.
(Srimad Bhagavatam-----1:13:33-----purport).
