Punjab, which experienced a series of great tragedies in the last century, will perhaps never forget the one that happened on the day of Baisakhi, April 13, 1919. The Jallianwala Bagh massacre, which came barely months after the Armistice on November 11, 1918 ended World War I in Europe, occurred as undivided Punjab was struggling and in ferment. A large number of people — estimates vary between 5,000 and 20,000 — gathered at Jallianwala Bagh on the day of Baisakhi. Brigadier General Reinald Dyer arrived at the Bagh with 50 soldiers, armed with .303 Lee–Enfield bolt-action rifles. Others had knives or khukris. His team fired 1,650 rounds in about 10 minutes, stopping only when they ran out of ammunition. He made no effort to provide medical aid to the wounded, saying it was not his duty and left the scene of devastation.
