Indian Rebellion of 1857
At first, the British were slow to respond, but they later took rapid action with heavy forces and brought their regiments from the Crimean War to India. They also redirected many of the regiments that were going to China to India. The British forces reached Delhi and surrounded the city from July 1 to August 31, 1857. Eventually, street-to-street fighting broke out between the British troops and the Indians. Ultimately, the British took control of Delhi. The massacre at Kanpur (July 1857) and the Siege of Lucknow (June to November 1857) were also critical.
