[8] The British authorities removed Rani Mohan Kumari from power and put Narayan Singh, a descendant of royal family but born of a low caste, as the king of Sambalpur.

By virtue of the Doctrine of Lapse, Lord Dalhousie annexed Sambalpur in 1849, as Narayan Singh had no male successor to succeed him.

[11][12] The Indian Rebellion of 1857 collapsed by the end of 1858 and law and order was restored by the British throughout India, but he continued his revolution.

The British seized the entire food-stock of the rebels, stopped all resources of the supply of food and other necessaries of life for them.

Major Impey abandoned the idea of violent war and cautiously followed the policy of peace and good-will with the approval of the Government of India.

Sambalpur was brought under the jurisdiction of the newly created Central Provinces on 30 April 1862; Veer Surendra Sai decided to surrender soon after.

They stepped down to organise a conspiracy and made sudden arrest of Veer Surendra Sai and all his relations, friends and followers.
