On April 9, 1816, Macquarie ordered three regiments to lead a military expedition ‘with secrecy and despatch’ against the ‘hostile natives’ in the Nepean Region. A list of those who were wanted in relation to violence was provided to each, however all Aboriginal people encountered were to be made ‘prisoners of war’.
‘On any occasion of seeing or falling in with the Natives, either in bodies or singly, they are to be called on, by your friendly Native Guides, to surrender themselves to you as Prisoners of War. If they refuse to do so, make the least show of resistance, or attempt to run away from you, you will fire upon and compell them to surrender, breaking and destroying the spears, clubs, and waddies of all those you take Prisoners. Such Natives as happen to be killed on such occasions, if grown up men, are to be hanged up on trees in conspicuous situations, to strike the Survivors with the greater terror. On all occasions of your being obliged to have recourse to offensive and coercive measures, you will use every possible precaution to save the lives of the Native Women and Children, but taking as many of them as you can Prisoners.’

Captain Wallis lead his regiment from Liverpool towards Appin, with the unwilling aid of two Dharawal guides Budbury and Bundle who later escaped and another guide, ex-convict John Warby.
