Jallianwala Bagh massacre
In Amritsar, over 5,000 people gathered at Jallianwala Bagh.  Michael O'Dwyer is said to have believed that this was part of an attempt to rebel against the British. James Houssemayne Du Boulay is said to have ascribed a direct relationship between the fear of a Ghadarite uprising in the midst of an increasingly tensed situation in Punjab, and the British response that ended in the massacre.
