Kunwar Singh led the revolt in Bihar (B), Rani Lakshmibai died in June 1858 (C), and the revolt began at Meerut in May 1857 (D). The British victory at Chinhat (E) in June 1857 temporarily established rebel control over Lucknow, but it was later recaptured by the British. The abolition of Sati (A) occurred earlier, in 1829.
