Tarhasi
Tarhasi lies in the uplands north-east of Palamau, where an old fort was known as Mangarh. During the Mughal campaigns against the Chero rulers, the army of Daud Khan advanced through this country towards their strongholds. The Chero chief offered tribute, but the demands made in return were rejected and the conflict continued. The route through Tarhasi formed part of the difficult approach from the plains into the wooded Palamau country.
