Coniston massacre
The board sat for 18 days in January 1929 to consider three incidents (Brooks, Morton and Tilmouth) that resulted in the deaths of Aboriginal people, and in one more day, finished its report, finding that 31 Aboriginal people had been killed and that in each case the death was justified.
Reginald Dyer
Sir Michael O'Dwyer, Lieutenant-Governor of Punjab from 1912 to 1919, endorsed Dyer and called the massacre a "correct" action. Some historians now believe he premeditated the massacre and set Dyer to work. Many Indians blamed O'Dwyer, and while Dyer was never assaulted, O'Dwyer was assassinated in London in 1940 by Udham Singh in retaliation for his role in the massacre.
