Towards the end of the year that the Pandavas spent at the Matsya Kingdom, Duryodhana (suspecting that the Pandavas were hiding in Matsya) attacked that kingdom. The army of Hastinapura stood at the borders of Matsya, but King Virata had already taken his entire army to fight the Trigarta army attacking from the south. When news arrives at the palace, Uttar confidently boasts about how he will single-handedly wipe out the Kauravas, downplaying their abilities. Upon the prodding of his mother and her maid, he takes his sister’s dancing teacher, the eunuch Brihannala, who was in reality Arjuna, as his charioteer. As they approach the Kuru army, Uttar panics at the site, and asks Brihannala to turn back. When he refuses, citing Kshatriya dharma, Uttar dismounts the chariot and runs for his life, only for Arjuna to run up to him and catch him. In order to fortify Uttar’s courage, Arjuna revealed his true identity. Uttar was incredulous and initially refused to believe Arjuna; only after Arjuna had recited his ten aliases did Uttar believe that Brihannala was indeed Arjuna in disguise. Arjuna then took charge and single-handedly defeated the entire Hastinapura army.
