Named for the enclosed park where it took place, the Jallianwala Bagh Massacre occurred in India on April 13, 1919, when British troops under the command of General Reginald Dyer opened fire without warning on a crowd of roughly 10,000 Indians protesting the arrest of two Indian National Congress leaders. At least 379 demonstrators were killed and another 1,200 were wounded during the barrage, which is said to have lasted 10 minutes. Who was killed 21 years later in retribution for the massacre?
