The British Army officer Dyer had commanded his troops to enter into the Jallianwalla Bagh on Baisakhi Day (April 13) and opened fire without a warning to the unarmed protestors, who were demanding an end to British rule in India. Dyer's troops fired and killed hundreds and stopped only when they ran out of ammunition. The Bagh, enclosed from all four sides with buildings, had only one main entrance that was blocked by Dyer's troops. Other smaller gates were locked and people fleeing from the firing were shot. Many of them jumped to their death in a well inside the garden.
