On the afternoon of April 13, a crowd of at least 10,000 men, women, and children gathered in the Jallianwala Bagh, which was nearly completely enclosed by walls and had only one exit. People had gathered in a peaceful protest defying the orders on public meetings and some had come to the city from the surrounding region to celebrate Baisakhi, a spring festival. The British Army officer Dyer and his soldiers arrived and sealed off the exit. Without warning, the troops opened fire on the crowd, reportedly shooting hundreds of rounds until 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. After they ceased firing, the troops immediately withdrew from the place, leaving behind the dead and wounded.
