Kumaragupta's Deccan Campaign

During the end Regin of Kumaragupta, he formed alliance with Bhavadatta Varman of Nala Dynasty and collective attacked the Vakataka dynasty as an ally together invaded the Deccan and captured as deep as Nandivardhana and captured it.
Invasion
The death of Pravarasena II may have triggered a succession struggle, with Narendrasena ultimately emerging as the victor. Vakataka inscriptions suggest that Narendrasena had to "regain the fortunes of his family" following an unspecified calamity, which many historians interpret as a reference to the aftermath of the succession conflict. However, A.S. Altekar proposes an alternative explanation, suggesting that the records actually describe an invasion by the Nala king Bhavadattavarman of Bastar and Kumaragupta of Gupta Empire, who were known to have advanced into Vidarbha and captured Nandivardhana, the former Vakataka capital.

Aftermath
Soon after the combined Invasion of Nalas and Guptas, in 445 CE during the end of Kumaragupta's reign, Narendrasena was able to recapture his past captial driving away the Gupta and Nala troops.
