Question

why did the troops of General Dyer opened fire on the gathering in the Jallianwala Bagh and what was the reaction of the nation to the incident?​

Answer 1

Answer:

Indians had gathered at the Jallianwala Bagh on the occasion of Baisakhi, a Sikh festival, defying the British diktat which prohibited mass gatherings. To teach Indians a "lesson" for their "disobedience", Brigadier-General Dyer ordered his troops to open fire on the gathering.

In India, Gandhi's call for protest against the Rowlatt Act achieved an unprecedented response of furious unrest and protests.
