Jallianvala Bagh Massacre, involved the killing of hundreds of unarmed, defenseless Indians by a senior British military officer, took place on 13 April 1919 in the heart of Amritsar, the holiest city of the Sikhs, on a day sacred to them as the birth anniversary of the Khalsa. Jallianvala Bagh,. a garden belonging to the Jalla, derives name from that of the owners of this piece of landin Sikh times. It was then the property the family of Sardar Himmat Singh , a noble in the court of Maharaja Ranjit Singh (1780-1839), who originally came from the village of Jalla, now in Fatehgarh Sahib district of the Punjab. The 1919 Amritsar massacre, known alternatively as the Jallianwala Bagh massacre after the Jallianwala Bagh (Garden) in the northern Indian city of Amritsar, was ordered by General R.E.H. Dyer. On Sunday April 13, 1919, which happened to be ‘Baisakhi’, one of Punjab’s largest religious festivals, fifty British Indian Army soldiers, commanded by Brigadier-General Reginald Dyer, began shooting at an unarmed gathering of men, women, and children without warning. Dyer marched his fifty riflemen to a raised bank and ordered them to kneel and fire. Dyer ordered soldiers to reload their rifles several times and they were ordered to shoot to kill. Official British Raj sources estimated the fatalities at 379, and with 1,100 wounded. Civil Surgeon Dr Williams DeeMeddy indicated that there were 1,526 casualties. However, the casualty number quoted by the Indian National Congress was more than 1,500, with roughly 1,000 killed. On April 13, the holiday of Baisakhi, thousands of Hindus, Sikhs and Muslims gathered in the Jallianwala Bagh (garden) near the Harmandir Sahib in Amritsar. Baisakhi is a Sikh festival, commemorating the day that Guru Gobind Singh founded the Khalsa Panth in 1699, and also known as the ‘Birth of Khalsa.’ During this time people celebrate by congregating in religious and community fairs, and there may have been a large number who were unaware of the political meeting.
