P: Settlers were driven from their Hunter Valley farms in late 1816. In September 1816 Magistrate William Cox outlined his plan to Governor Macquarie to put five parties of soldiers, settlers and guides into the field to scour the Grose, Hawkesbury and Nepean Rivers. There were no reports of Aboriginal casualties from these expeditions. Despite the apparent lack of Aboriginal casualties fighting ceased on the Hawkesbury Nepean River system in 1816. Governor Macquarie was generous in his rewards. Cox received payments in October 1816 and February 1817. Serjeant Broadfoot also received two payments. The guides received land grants for their services. Breastplates were made for Aboriginal guides. Macquarie's April 1817 report to Bathurst, while highlighting the success of his measures, made no mention of Aboriginal casualties. Apart from the silence of the land there are other records that point to something catastrophic happening to the Aboriginal people of the Hawkesbury Nepean in 1816. The Macarthur letters noted the absence of Aboriginal people upon their return in 1817. George Bowmans' 1824 memorandum to Magistrate Scott recalled soldiers indiscriminately killing Aboriginal people. The ministers, Threlkeld and Lang, both had stories of killings on the Hawkesbury. Prosper Tuckerman recalled his father tell him that 400 Aboriginal people had been killed at that time. In 1834, John Dunmore Lang wrote: "There is black blood at this moment on the hands of individuals of good repute in the colony of New South Wales of which all the waters of New Holland would be insufficient to wash out the indelible stains."
