Mbh 2.23.1c

It was thus that those heroes fought with each other. The citizens consisting of thousands, of Brahmanas, Kshatriyas and Vaisyas and Sudras, and even women and the aged, O tiger among men, came out and gathered there to behold the fight. And the crowd became so great that it was one solid mass of humanity with no space between body and body. The sound the wrestlers made by the slapping of their arms, the seizing of each other’s necks for bringing each other down, and the grasping of each other’s legs for dashing each other to the ground, became so loud that it resembled the roar of thunder or of falling cliffs. Both of them were foremost of mighty men, and both took great delight in such encounter. Desirous of vanquishing the other, each was on the alert for taking advantage of the slightest lapse of the other. And, O monarch, the mighty Bhima and Jarasandha fought terribly on in those lists, driving the crowd at times by the motions of their hands like Vritra and Vasava of old. Thus two heroes, dragging each other forward and pressing each other backward and with sudden jerks throwing each other face downward and sideways, mangled each other dreadfully. And at times they struck each other with their knee-joints. And addressing each other loudly in stinging speeches, they struck each other with clenched fists, the blows descending like a mass of stone upon each other. With broad shoulders and long arms and both well-skilled in wrestling encounters, they struck each other with those long arms of theirs that were like maces of iron. That encounter of the heroes commenced on the first (lunar) day of the month of Kartic (October) and the illustrious heroes fought on without intermission and food, day and night, till the thirteenth lunar day. It was on the night of the fourteenth of the lunar fortnight that the monarch of Magadha desisted from fatigue.
