Mbh 7.190.1b

Between those four warriors of thy army and those three of the Pandava side, the battle that took place was exceedingly dreadful but divested of everything unfair. Then Dhrishtadyumna, exceedingly quick in the use of weapons, beholding those brave and mighty car warriors of thy army checked by the twins (Nakula and Sahadeva), proceeded towards Drona. Checked by those two lions among men, those four heroic warriors encountered the former like the wind assailing a couple of mountains (standing on their way). Each of the twins--those great car-warriors--was engaged with a couple of arrows against Drona. Beholding the invincible prince of the Panchalas proceeding against Drona, and those four heroes (of his own army) engaged with the twins, Duryodhana, O monarch, rushed to that spot, scattering showers of blood-drinking arrows. Seeing this, Satyaki quickly approached the Kuru king. Those two tigers among men, viz., the two descendants of Kuru and Madhu, approaching each other, became desirous of striking each other in battle. Recalling to mind their behaviour towards each other in childhood and reflecting with pleasure on the same, they gazed at each other and smiled repeatedly. Then king Duryodhana (mentally), blaming his own conduct, addressed his ever dear friend Satyaki, and said, “Fie on wrath, O friend, and fie on vindictiveness! Fie on Kshatriya usage, and fie on might and prowess, since thou aimest thy weapons at me, and I too am aiming at thee, O bull of Sini’s race! In those days thou wert dearer to me than life itself, and I also was such to thee! Alas, all those acts of childhood that I remember, of both thyself and mine, became quite insignificant in the field of battle! Alas, moved by wrath and covetousness, we are here to-day for fighting against each other, O thou of the Satwata race!”
