Ghatotkacha kills Alambusha

After the death of Jayadratha, Krishna said to Arjuna - Let us rush to Yudhistira. He would be anxious for us. They also went to Yudhistira who was relieved to see them. They told him about the death of Jayadratha.

In the Kaurava camp, Duryodhana gave orders that there would be no rest. Torches would be lit and the fight would happen in the night also. The Pandava army hearing also lit up torches.

Drona tried to capture Yudhistira but was stopped by Dhristadyumna. Drona wounded Dhristadyumna, who then fled. Satyaki then attacked Drona. Satyaki also was wounded by Drona. When Yudhistira was wondering what would happen, Hidimba's son, Ghatotkacha, came to his rescue. Taking his mace, Ghatotkacha blasted his way into the Kaurava army. He was followed by Sahadeva, son of Jarasandha, five sons of Draupadi and Yudhistira.

Ghatotkacha made his body like a mountain. He then started eating up the Kaurava soldiers. Doshan, son of Dushsasana attacked Ghatotkacha. Ghatotkacha smashed his chariot and Doshan barely escaped. Ghatotkacha,  seeing this, brought his mace down on Doshan, killing him.

Seeing this angered Dushsasana who attacked but had to flee, not able to stand the might of Ghatotkacha.
Using the magic of the rakshasas, Ghatotkacha played havoc on the Kauravas.

Seeing all perplexed, Karna decided to attack. Ghatotkacha smashed Karna's chariot and Karna barely managed to save himself.  Ashwatthama then came but could stand the might of Ghatotkacha.

Alambusha then came into the attack. Ghatotkacha and Alambusha began fighting each other. Alambusha hid in the skies and Ghatotkacha went and caught up with him. Alambusha started showering arrows and Ghatotkacha broke his bow. Both then began fighting with their maces. Alambusha took the form of a mountain range and attacked Ghatotkacha. Ghatotkacha climbed up on the mountain and began smashing till he saw Alambusha. He caught Alambusha by his hair and dragged him to the ground. With his mace, he then smashed his head. 

Day Five

Battle began at dawn. While the kuru army used a formation like an ocean, the Pandavas used a horned formation.
Many horses, elephants and soldiers were killed.
Bhishma was on a rampage. Seeing this, Bhima attacked Bhishma. Bhima avoiding the arrows with his mace, killed the charioteer and horses of Bhishma's chariot. Bhishma climbed onto another chariot and started a fresh attack. Avoiding Bhima, Bhishma went where Arjuna was. Krishna also took the chariot near Bhishma. While Arjuna and Bhishma fought, Bhima, Nakula and Sahadeva killed many Kaurava soldiers. Ilavanta, son of Arjuna came to fight there.
When Arjuna was in exile, he had been captured by Uloopi, daughter of a Naga. This was their son. Ilavanta had grown up in heaven, learning under Indra. When Arjuna had gone to the heaven, he had met his son there.
The sons of Shakuni attacked Ilavanta. Ilavanta killed them. Seeing this, Duryodhana came to fight. Seeing no respite, he asked the demon Alambusha to attack.
Ilavanta fought valiantly, combating Alambusha. Alambusha fainted and Ilavanta kept killing the soldiers of the Kauravas. Seeing his army getting killed, Duryodhana attacked. Duryodhana had to flee, seeing the might of the young man. Ilavanta then cut off the weapons of all the kings who came to help Duryodhana.
Alambusha coming to his senses attacked Ilavanta again. The two fought with each other, sometimes with arrows, sometimes with swords.
Alambusha hid behind the clouds and Ilavanta caught him. Soon Alambusha caught up with Ilavanta and struck him with his sword.
Ilavanta fell dead. Seeing this, Ghatotkacha attacked Alambusha.
Hearing off the death of his son, Arjuna attacked whoever came in front of him. Bhishma cut off his arrows. Arjuna used the fire arrow to burn Bhishma's chariot. Bhishma invoked water and the fire went out. Arjuna then used the wind to evaporate the water.
The fight between Arjuna and Bhishma continued till it was the end of the day.
