Coniston massacre
The Coniston massacre, which took place near the Coniston cattle station in the then Territory of Central Australia (now the Northern Territory) from 14 August to 18 October 1928, was the last known officially sanctioned massacre of Indigenous Australians and one of the last events of the Australian Frontier Wars. People of the Warlpiri, Anmatyerre, and Kaytetye groups were killed. The massacre occurred in revenge for the death of dingo hunter Frederick Brooks, killed by Aboriginal people in August 1928 at a place now known as "Yukurru", also known as Brooks Soak.
Kesh ambush
However, according to Conflict Archive on the Internet, there was a gun battle at the scene of the attempted bombing, between a number of IRA men and British troops in which Mac Giolla Bhrighde was killed. A British Army soldier, Lance Corporal Al Slater, from Leicestershire, was also killed in the exchange of fire, further contradicting the Republican sources. Charles "Nish" Bruce served with Slater on this operation. His autobiography, "Freefall", under the pseudonym "Tom Read", recounted in detail an exchange of fire and the respective deaths of both Slater and Mac Giolla Bhrighde. Andy McNab, a former SAS soldier, supported this view in his book "Immediate Action". Mac Giolla Bhrighde's companion, Ciaran Fleming, drowned in the swollen Bannagh River as he tried to get away.
