Mbh 4.64.1a

Vaisampayana said, “After Bhishma had fled, leaving the van of battle, the illustrious son of Dhritarashtra hoisting high his flag approached Arjuna, bow in hand and setting up a loud roar. And with a spear-headed shaft shot from his bow stretched to the ear, he pierced on the forehead of that terrible bowman of fierce prowess, Dhananjaya, ranging amidst the foes. And pierced with that keen shaft of golden point on the forehead, that hero of famous deeds looked resplendent, O king, like unto a beautiful hill with a single peak. And cut by that arrow, the warm life-blood gushed out profusely from the wound. And the blood trickling down his body shone beautifully like a wreath of golden flowers. And struck by Duryodhana with the shaft, the swift-handed Arjuna of unfailing strength, swelling with rage, pierced the king in return, taking up arrows that were endued with the energy of snakes of virulent poison. And Duryodhana of formidable energy attacked Partha, and Partha also, that foremost of heroes, attacked Duryodhana. And it was that those foremost of men, both born in the race of Ajamida, struck each other alike in the combat. And then (seated) on an infuriate elephant huge as a mountain and supported by four cars, Vikarna rushed against Jishnu, the son of Kunti. And beholding that huge elephant, advancing with speed, Dhananjaya struck him on the head between the temples with an iron arrow of great impetus shot from the bow-string stretched to the ear. And like the thunderbolt hurled by Indra splitting a mountain, that arrow furnished with vulturine wings, shot by Partha, penetrated, up to the very feathers, into the body of that elephant huge as hill. And sorely afflicted by the shaft, that lord of the elephant species began to tremble, and deprived of strength fell down on the ground in intense anguish, like the peak of mountain riven by thunder.
