British ears, retribution was swift and unforgiving. Rebellious Indians were tracked down and executed in ways calculated to instill terror and regret. One or two were even fired from cannons, or so it is often recorded. Untold numbers were shot or summarily hanged. The whole episode left Britain profoundly shaken. More than five hundred books appeared on the uprising in its immediate aftermath. India, it was commonly agreed, was too big a country and too big a problem to leave in the hands of a business. Control of India passed to the British crown, and the East India Company was wound up.
