There was no warning and no notice, but Dyer gave order to shoot at the crowd. For about ten minutes, bullets were showered through the crowd of innocent and unarmed people who came to hear their leaders speak. 

They were shocked when they heard the bullet shots and they turned round to see scores of their people falling to the bullets, and they ran helter skelter, not knowing where to hide and how to get out of the ground around which the buildings stood as tall walls. 

Only very few could escape from the ground of death and about 400 hapless Indian men and women died at the spot. Three times of the number were the people who were seen struggling between life and death, bleeding through the bullet wounds. 

Dyer and his soldiers left the place soon after, without caring for the dead and the wounded, not even making arrangements to give at least drinking water to the wounded or giving first aid. Later, even the official reports admitted that 400 people had been killed and between 1,000 and 2,000 wounded. 

Gandhi had made an unofficial enquiry about the Jallianwalla Bagh and he estimated 1,200 dead and 3,600 wounded.
