How was it possible for Arjuna to fight such an impressive record battle on the fourteenth day? Satyaki was the star performer on that day. Arjuna simply rushed forward , mostly ducking prominent warriors like Drona and Kritavarman. Satyaki demolished Kauravas more than Arjuna himself on 14th day.. We saw not foot-soldiers or car-warriors or elephants or horsemen or steeds that were not struck with Yuyudhana's arrows. Not even Phalguna, O king, had caused such a carnage there as Satyaki, O monarch, then caused among those troops. That bull among men, viz., the dauntless grandson of Sini, endued with great lightness of hand and displaying the utmost skill, fighteth, surpassing Arjuna himself. …. Numerous heroes, of whom Kritavarman is the first, contending vigorously in battle, could not slay Yuyudhana. The latter, without doubt, will slay my sons. Phalguna himself fought not in the manner in which the renowned grandson of Sini has fought.' Arjuna arrived in Jayadratha’s vicinity even before afternoon but was checked by members in the Suchi vyuha(innermost array). Soldiers in the outer shell, viz Padma vyuha acted as reserves., most probably. It was satyaki who shattered this array killing several soldiers and defeated prominent warrior like Duryodhana, Dusshasana and Kritavarman back to back multiple times. He single handedly resisted Samsaptaka(Trigarta) army too on that day. Then King Duryodhana, seeing Duhsasana thus covered with arrows, urged a body of Trigartas towards the car of Yuyudhana. Those Trigarta car-warriors, of fierce deeds, accomplished in battle, and numbering three thousand, proceeded towards Yuyudhana. Firmly resolved upon battle and swearing not to retreat, all of them encompassed Yuyudhana with a large throng of.cars, Soon, however, Yuyudhana struck down five hundred of their foremost warriors stationed in the van of the force as it advanced towards him in battle, shooting showers of arrows at him. Speedily slain by that foremost one amongst the Sinis with his shafts, these fell down, like tall trees from mountain-tops uprooted by a tempest. And the field of battle, strewn with mangled elephants, O monarch, and fallen standards, and bodies of steeds decked in trappings of gold, and torn and lacerated with the shafts of Sini's grandson and weltering in blood, looked beautiful, O king, like a plain overgrown with flowering Kinsukas. Those soldiers of thine, thus slaughtered by Yuyudhana, failed to find a protector like elephants sunk in a morass. Then all of them turned towards the spot where Drona's car was, like mighty snakes making towards holes from fear of the prince of birds Later Bhimasena too caused massive carnage among the Kauravas. It was not Arjuna's feat alone. Satyaki and Bhimasena assisted Arjuna in battling Karna towards end of the day, who stood protecting Jayadratha. Having caused an immense slaughter in thy army, the mighty and invincible Dhananjaya, of prowess incapable of being baffled came upon the ruler of the Sindhus. Karna, however, O king, with his arrows, resisted him in that battle in the very sight, O Bharata, of Bhimasena and Satwata. The mightyarmed Partha, in the very sight of all the troops, pierced the Suta's son, in return, with ten arrows, on the field of battle. Then Satwata, O sire, pierced Karna with three arrows. And Bhimasena pierced him with three arrows, and Partha himself, once more, with seven. The mighty car-warrior, Karna, then pierced each of those three warriors with sixty arrows. And thus, O king, raged that battle between Karna alone (on one side) and the many (on the other). The prowess, O sire, that we then beheld of the Suta's son was wonderful in the extreme, since, excited with wrath in battle, he singly resisted those three great car-warriors. Then the mighty-armed Phalguna, in that battle, pierced Karna, the son of Vikartana, in all his limbs with a hundred arrows. All his limbs bathed in blood, the Suta's son of great prowess and bravery, pierced Phalguna in return with fifty arrows. Beholding that lightness of hand displayed by him in battle, Arjuna brooked it not. Cutting off his bow, that hero, viz., Dhananjaya, the son of Pritha, quickly pierced Karna in the centre of the chest with nine arrows, Then Dhananjaya, with great speed at a time, when speed was necessary shot in that battle a shaft of solar effulgence for the destruction of Karna. Drona's son, however, with a crescent-shaped arrow, cut off that shaft as it coursed impetuously (towards Karna) Everyone mentioned about Arjuna's valor, But IMO Satyaki performed better than Arjuna on that day. Bhimasena too proved his mettle., but not as impressive as the other two. The important factor was, Shiva's boon of victory on 14th day.
