[2] At the onset of his reign, Sukhrangpha faced a serious threat from his youngest brother Chao Pulai (or Tai Sulai).
Chao Pulai gathered his supporters and along with troops sent by his uncle, the king of Kamata, marched against Sukhranphaa.
[5] During Ahom period in Assam, the heirs apparent to the throne were appointed as Charing Raja.
His ultimate fate differ in different account, as some stated that Sukhrangpha had him executed for his crime[8] while another account stated that Chaopang Banduk Borgohain escaped being put to death under the king's orders by concealing himself until the affair had blown over and later he was subsequently forgiven and taken back into favour.
Eminent Assamese historian Gunaviram Barua stated in his documents that Sukhranphaa expanded his kingdom towards the bank of Brahmaputra river by defeating the neighbouring tribal chieftains, who were unable to face his prowess.
