Mahabharata Drona Parva Chapter 170:3

Mahabharata Drona Parva (Ghatotkacha-badha Parva) Chapter 170:3 Then those two warriors, stringing two other bows, capable of inspiring enemies with terror, began to pierce Yuyudhana from every side with keen shafts. During the progress of that fierce conflict that was so destructive of heroes the loud twang of Gandiva, O king, was heard over every other sound. Hearing then the rattle of Arjuna's car as also that twang of Gandiva, the Suta's son, O king, said these words unto Duryodhana, "Slaughtering our entire army and the foremost of heroic warriors and many mighty bowmen among the Kauravas, Arjuna is loudly twanging his bow. The rattle also of his car is heard, resembling the roar of the thunder. It's evident, the son of Pandu is achieving feats worthy of his own self. This son of Pritha, O monarch, will grind our large host. Many of our troops are already breaking. No one stays in battle. Indeed, our army is being dispersed like a risen mass of clouds dispersed by the wind. Encountering Arjuna, our host breaks like a boat on the ocean. The loud wails, O king, of the foremost of warriors, O monarch, flying away from the field, or falling down in consequence of the arrows sped from Gandiva, are being heard. Hear, O tiger among car-warriors, the sound of drums and cymbals near Arjuna's car at dead of night, resembling the deep roll of thunder in the welkin. Hear also the loud wails (of afflicted combatants) and the tremendous leonine shouts, and diverse other noises in the vicinity of Arjuna's car. Here, however, this Satyaki, this foremost one of the Satwata race, stayeth amid us. If this object of our aim can be struck down, we can then vanquish all our foes. Similarly, the son of the Panchala king is engaged with Drona. He is encompassed on all sides by many heroic and foremost of car-warriors. If we can slay Satyaki and Dhrishtadyumna, the son of Prishata without doubt, O king, victory will be ours. Surrounding these two heroes, these two mighty car-warriors, as we did the son of Subhadra we will strive, O king, to slay them, viz., this son of Vrishni's race and this son of Prishata. Savyasachin, O Bharata, is before us, coming towards this division of Drona, knowing that Satyaki is engaged here with many chiefs among the Kurus. Let a large number of our foremost of car-warriors proceed thither, so that Partha may not be able to come to the rescue of Satyaki, now encompassed by many.
