Bhima kills Dushshasana

Krishna and Arjuna returned to the battlefield. Bhima took stock of how many weapons he still had with him. Arjuna covered the sky with his arrows. Shakuni said to Duryodhana - See, Arjuna is destroying our army.
Bhima's attack was ferocious. Karna came to attack. He started killing the Pandava army with his arrows.
Arjuna said to Krishna - See Karna there. He is killing off our soldiers and defeating our warriors.
Krishna smiled and turned the chariot towards Karna. Seeing this, Duryodhana said to Karna - See there come the greatest heroes of all time. Get your army together and kill Arjuna today.

Along with Ashwatthama and Dushsasana, Karna faced Arjuna.
Bhima with his mace tried to kill off the army but Dushshasana shot arrows wounding him. Like a made elephant, Bhima took his mace and rushed towards him. With the blows, he destroyed Dushshasana's chariot, charioteer and horses. Remembering his promise, he went where the Kaurava prince was and caught him. Taking a sword he brought it down on him, cutting his chest. With his hands, he plucked his heart out. He then drank Dushsshasana's blood.

 Duryodhana and Karna were seeing this. Karna tried to control Bhima but could not. Bhima ran around, his face smeared with blood. Thinking this was a rakshasa, anyone who came close to him, ran away.

Duryodhana was sad at the death of his brother. 

Arjuna and Bhima create havoc

The next day the fight began. Arjuna started showering arrows killing anyone who came in the path. Seeing this Duryodhana climbed on a chariot and came to face Arjuna. He aimed arrows at Arjuna which were cut off. Arjuna then cut off the flag staff, horses and the charioteer. Duryodhana then picked up a mace and flung that at Arjuna. The chariot was hit by the mace and started shaking. Arjuna then shot arrows at Duryodhana, who had to flee.
Ashwatthama seeing this came to fight Arjuna. Both started shooting arrows at each other. Soon, hit by an arrow of Arjuna, Ashwatthama fainted. The charioteer then fled with the fainted warrior.

Dushsasana and Bhima were fighting. Dushsasana was on an elephant. Bhima attacked the elephant. The elephant fell and Dushsasana fled. Bhima then began killing who came in front. Seeing this, Ashwatthama attacked Bhima. Seeing the son of Drona, Bhima climbed up on his chariot and picked up a bow. Ashwatthama shots arrows at Bhima which caused him to loose his senses. regaining his sense, Bhima flung his mace at the chariot, breaking it. Ashwatthama then jumped onto another chariot and began shooting arrows which were all cut off by Bhima. Bhima then flung his mace, breaking the chariot. Ashwatthama fled. Bhima tried to chase him. Seeing this, Karna stopped Bhima by showering arrows at him. Bhima using his mace crushed Karna's chariot. Karna got another chariot and fled.
Bhima then attacked the army.
Arjuna was killing the Kaurava army. Seeing this, Duryodhana went to Drona and said You said you would be capturing Yudhistira. I do not see that happening. On the contrary, I see Bhima and Arjuna making a mess of my army. if Karna had been made the commander, I would have had Yudhistira as my prisoner.
Drona was angry. He said I had said earlier that I am a brahmin and I should be in the war.
Saying this, Drona decided to walk away.
Shakuni then said to Drona - Duryodhana did not mean anything bad.
Drona was pacified. He said I can capture Yudhistira only if Arjuna is away.

The day ended and all went back to the camp.
