Who administered the revolt of 1857 in Bihar?

The Revolt of 1857 was a major uprising in India against the rule of the British East India Company which began in Delhi but soon filtered to various other parts of the country. In Bihar, it was led by Kunwar Singh, an eighty-year-old Rajput zamindar of Jagdishpur. He led a select band of armed soldiers against the troops under the command of English army chief Milmel, Col. Dax, Mark and Major Delus. He won the initial battle and was able to regain his Kingdom in April 1858. But later on in the same month he lost the final battle and also lost his life in the process.
