When Duryodhana came to know that Kichaka was killed, he was sure that the Pandavas were in Viratnagar because nobody other than Bhima was strong enough to kill him. Duryodhana decided to attack Viratnagar and capture the Pandavas.

Susharma, the ruler of Trijata, was the enemy of King Virata. He also decided to attack Viratnagar. He joined hands with Duryodhana. Both Susharma and Duryodhana attacked  Viratnagar from two sides and captured a large territory and cattle. King Virata got frightened. But Yudhisthira offered to help him. Accompanied by the other Pandavas, he fought from king Vitrata's side. The armies of Susharma and Duryodhana started losing. But Susharma played a trick and captured Virata. Yudhisthira said to Bhima, "King Virata has given us shelter. It is our duty to protect him." Bhima defeated Susharma and rescued Virata.

Meanwhile, Duryodhana had taken away hundreds of cattle of Viratnagar. Virata sent his son Uttar to fight him. Arjuna, who was working as the royal music teacher, became his charioteer. Faced with the huge army of Duryodhana, Uttar got scared. Seeing this Arjuna started fighting with Duryodhana. Duryodhana immediately recognised Arjuna and was very happy that the Pandavas were discovered in the thirteenth year was already over. Arjuna bravely fought the Kaurava army and in no time defeated them, freeing all the cattle. When the news of victory reached King Virata, there was jubilation everywhere.
