Early relationships between Noongars and colonists at the
Swan River Colony have been documented, demonstrating the existing occupants of the Swan and Canning River area's opposition to colonisation, initially manifested by shouted warnings and aggressive postures, but increasingly through hostility and violence. Lieutenant Governor
James Stirling, in his proclamation of the colony in June 1829, warned that Aboriginal people were protected by British laws and any colonist convicted of "behaving in a fraudulent, cruel or felonious Manner towards the Aborigines of the Country" would be dealt with "as if the same had been committed against any other of His Majesty's subjects". Nonetheless, the first ten years of colonisation witnessed a significant level of violence in which a number of Europeans and Aboriginal people died. The actual death toll is unknown, but the number of Aboriginal dead far exceeds the losses in the European community. Swan River colonisers in the first four years of the settlement initially failed to record the names of the Aboriginal people of the Swan River region, but it is highly likely that Midgegooroo would have been one of those who observed the first British explorations in 1827 and the subsequent establishment in June 1829 of the port of Fremantle, the capital at Perth, satellite settlements at Guildford and further inland at York, and the network of small farms around the area. His first appearance in the colonial record may have been in May 1830 when an old man, tentatively identified by
Sylvia Hallam and Lois Tilbrook as Midgegooroo, was found plucking two turkeys which had been stolen from a farm on the Canning River and subsequently beaten by a military detachment. The next day, a group of eight Aboriginal men, including "Dencil", attacked a farm near Kelmscott and injured a settler named J.R. Phillips "with whom they had always been friendly". If Hallam and Tilbrook are correct that the old man was Midgegooroo, he would have been subjected to European violence in retaliation for actions he did not fully comprehend quite early in their colonisation. In December 1830, Midgegooroo was camping by
Galup when two white labourers, who were passing by, stopped to shake hands with a group of Aboriginal women. When the two men returned later that day, Midgegooroo scared them off by threatening to spear one of them. In approximately February 1831, Midgegooroo was reported to have come to
Lionel Samson's store in Fremantle and was given biscuits by a servant James Lacey. A few weeks later, Midgegooroo was involved in an incident that came to play a crucial part in his eventual execution. In apparent retaliation for the killing of an Aboriginal man who was taking potatoes and a fowl from the farm of Archibald Butler near
Point Walter, Midgegooroo and Yagan attacked Butler's homestead and killed a servant named Erin Entwhistle, whose son Ralph, then aged about ten, gave a deposition identifying Midgegooroo as the principal offender: In May 1833, colonist Charles Bourne recalled having sat on a jury inquiring into the death of Entwhistle which heard the evidence of Ralph Entwhistle and his younger brother. Charles Bourne figured again in the story when, in about May 1832, Midgegooroo and his wife attempted to break into their house in Fremantle. "My wife told me", he recalled, "that they had thrown two spears at her, and I saw the spears laying on the floor. Their violence was such that my wife was obliged to take a sword to them." Later he was reported as having tried to take provisions from Thomas Hunt at his sawpit on the
Canning River. Finally, he was reported as having set his
dingos on a settler's
pigs. A police constable Thomas Hunt reported that he had known Midgegooroo for three years: In May 1832, Yagan was arrested for the murder of William Gaze on the Canning River, an incident that lead to his declaration as an outlaw, imprisonment on
Carnac Island with Lyon, and subsequent escape. In March 1833, a number of Noongar men from
King George Sound visited Perth at the instigation of the government. This was the second visit of King George Sound people that year, apparently for the purpose of encouraging "amicable relationships on the Swan like those at the Sound". Yagan and ten of his countrymen had met the first visitors at Galup and, when the next group arrived, he was keen to present a corroboree for them in Perth before an "overflowing audience", which included the Lieutenant Governor Frederick Irwin. Yagan acted as "
master of ceremonies, and acquitted himself with infinite dignity and grace". Although Yagan's group was referred to as "Midgegooroo's group", it is unclear whether the old man also attended. In April 1833, an incident occurred in Fremantle that led to the declaration of Midgegooroo and Yagan as outlaws. A group of Aboriginal people, including a classificatory brother of Yagan named Domjun, broke into stores occupied by Mr. Downing. William Chidlow, who lived nearby: The next morning, Yagan and a number of others crossed the Swan River near
Preston Point and told Mr. Weavell's servant they were going to the Canning River to "spear 'white man', and fixing his spear into a throwing stick, he rushed into the bush, followed by his infuriated tribe". At noon, Yagan, Midgegooroo, Munday, Migo and "about 30 Natives", who "appeared to be friendly", encountered Mr. Phillips and four other white men, including Thomas and John Velvick, who were employed as farm labourers at the entrance of Bull's Creek on the Canning River. The white men were loading a quantity of provisions for Phillips' farm at Maddington, onto carts when Midgegooroo inquired about the number of men in the first cart which had already left the scene. According to a witness, Thomas Yule:
Frederick Irwin described the episode in his dispatch to the Secretary of State for Colonies: According to his account, Irwin immediately conferred with his Executive Council "to take such steps for a prompt and summary retaliation, as the means at my disposal admitted". A proclamation was issued and published in the
Perth Gazette offering a reward of
£30 for the capture "dead or alive" of Yagan, and £20 of Midgigooroo and Munday, equivalent to and respectively in . The proclamation declared Yagan, Midgegooroo and Munday to be outlaws;
Frederick Irwin rationalized his actions to the Secretary of State in the following terms: ==Capture and execution==
