The Jallianwala Bagh Massacre took place on 13 April 1919 and it remained a turning point in the history of India's freedom movement. In Punjab, there was an unprecedented support to the Rowlatt Satyagrha. Facing a violent situation, the Government of Punjab handed over the administration to the military authorities under General Dyer. He banned all public meetings and detained the political leaders. On 13th April, the Baisakhi day (harvest festival), a public meeting was organized at the Jallianwala Bagh (garden). Dyer marched in and without any warning opened fire on the crowd. The firing continued for about 10 to 15 minutes and it stopped only after the ammunition exhausted.
