Ammana was a pleasure-loving man, who was fond of dance and music. Ramachandra overthrew him sometime in the second half of 1271 CE. According to an inscription of Ramachandra, he and his followers entered the Devagiri fort disguised as actors, and arranged a performance before Ammana. During the performance, they suddenly unmasked themselves, and seized Ammana and his supporters.
This veracity of account is also supported by literary texts such as Bhanuvilasa (a Mahanubhava text) and Nagadeva-Charita of Parashurama-Vyasa. According to the Mahanubhava texts, Ramachandra blinded Ammana. Parashurama Vyasa's Nagadeva-Charita states that Ramachandra killed Ammana, and that Ramachandra's ultimate defeat against the Muslims was a result of this sin. The veracity of this claim is doubtful, since the other texts only mention the blinding, not the killing. Ammana may have died a natural death in prison.
