Mbh 7.90.2b

Struck with Arjuna’s shafts, thousands of steeds fell down like swans on the breast of Himavat, struck down by the force of watery current. Like the Sun, that rises at the end of the Yuga, drying up with his rays, vast quantities of water, the son of Pandu, by his showers of weapons and arrows, slew a vast number of car-warriors and steeds and elephants and foot-soldiers. Then like the clouds covering the sun, the Drona-cloud, with its arrowy showers, covered the Pandava-sun, whose rays in the shape of thick showers of arrows were scorching in the battle the foremost ones among the Kurus. And then the preceptor struck Dhananjaya at the breast with a long shaft shot with great force and capable of drinking the life-blood of every foe. Then Arjuna, deprived of strength, shook in all his limbs, like a hill during an earthquake. Soon, however, regaining his fortitude, Vibhatsu pierced Drona with many winged arrows. Then Drona struck Vasudeva with five arrows. And he struck Arjuna with three and seventy arrows, and his standard with three. Then, O king, the valorous Drona getting the better of his disciple, within the twinkling of an eye made Arjuna invisible by means of his arrowy showers. We then beheld the shafts of Bharadwaja’s son falling in continuous lines, and his bow also was seen to present the wonderful aspect of being incessantly drawn to a circle. And those shafts, countless in number, and winged with the Kanka feathers, shot by Drona in that battle, incessantly fell, O king, on Dhananjaya and Vasudeva. Beholding then that battle between Drona and the son of Pandu, Vasudeva of great intelligence began to reflect upon the accomplishment of the (important) task. Then Vasudeva, addressing Dhananjaya, said these words: “O Partha, O thou of mighty arms, we should not waste time. We must go on, avoiding Drona, for a more important task awaits us.” In reply Partha said unto Krishna, “O Kesava, as thou pleasest!”
