On the sixteenth day, Karna was made the supreme commander of the Kuru army.
Karna fought valiantly but was surrounded and attacked by Pandava generals, who were unable to prevail upon him.
Karna inflicted heavy damage on the Pandava army, which fled.
Then Arjuna successfully resisted Karna's weapons with his own and also inflicted casualties upon the Kaurava army.

Karna's son Banasena was killed by Bhima in front of Karna himself, and later, when Bhima and Karna fought, Karna was on the verge of death but was left alive by Bhima to help Arjuna fulfill his vow of killing Karna.

On the same day, Bhima swung his mace and shattered Dushasana's chariot.
Bhima seized Dushasana, ripped his right arm from his shoulder, and killed him, tearing open his chest, drinking his blood, and carrying some to smear on Draupadi's untied hair, thus fulfilling his vow made when Draupadi was humiliated.
The sun soon set and with darkness and dust making the assessment of proceedings difficult, the Kaurava army retreated for the day.
