In response to their demands, Lieutenant-Colonel Kenneth Snodgrass, Acting Governor of New South Wales sent a large Mounted Police party north to investigate and repress such attacks.

The Mounted Police party, led by Major Nunn and composed of around twenty troopers, reached Liverpool Plains in January 1838.

In the ensuing melee they shot and killed a number of Aboriginal people in what became known as the Waterloo Creek massacre.

In the following months stockmen from stations along the Gwydir River organised into armed groups and scoured the country side in what is described by Reece as "a concerted campaign to get rid of all the Aborigines in the district."

The original party assembled at Bengari on a station owned by Archibald Bell before they set off and were joined by the remaining members somewhere along the Gwydir River.

When the station hand, George Anderson, asked what they intended to do with the Aborigines, he was told they were taking them over the back of the range to frighten them.

Magistrate Edward Day noted in his inquiry, "[I] took George Anderson with [me], believing that [his] life would be in danger if he remained at Myall Creek".

The Attorney General arrested seven of the men on additional charges, for the murder of an Aboriginal male named Charley.

Governor George Gipps later wrote that none of the seven attempted to deny their crime, though all stated they thought it extremely hard that white men should be put to death for killing blacks.

[16] On 18 December 1838, after all legal objections were exhausted and the Executive Council rejected petitions for clemency, the sentences were carried out.
