A letter written by Tatya Tope in 1857 has been found in the Madhya Pradesh archives under the Gyan Bharatam Mission. Tatya Tope (1814-1859) was a key leader of the Revolt of 1857. He served under Nana Saheb, the adopted son of Baji Rao II, led important battles at Kanpur, fought alongside Rani Lakshmibai and later took control of rebel forces at Gwalior. He kept up resistance in central India through guerrilla warfare until the British captured him, tried him and executed him in 1859.
