100 years of Jallianwala Bagh massacre: When Earth turned red with blood of innocents

The massacre took place at Jallianwala Bagh in Amritsar during the Baisakhi festival in April 1919 when troops of the British Indian Army under the command of Colonel Dyer opened fire at a crowd of people holding a pro-independence demonstration, leaving several dead and scores injured.
The number of casualties on April 13, 1919 is unclear, with colonial-era records showing 379 deaths while Indian figures put the number at closer to 1,000.
