grazing in Wiradjuri country. From 1822 to 1824 Windradyne led a group of 50-100 Aboriginal men in raids on livestock and stockmen's huts resulting in the death of 15-20 colonists. Martial law was declared in August 1824 and ended five months later when Windradyne and 260 of his followers ended their armed resistance. Estimates of Aboriginal deaths in the conflict range from 15 to 100. After two decades of sporadic violence between settlers and Aboriginal Tasmanians in Van Diemen's land, the Black War broke out in 1824, following a rapid expansion of settler numbers and sheep grazing in the island's interior. When Eumarrah, leader of the North Midlands people, was captured in 1828 he said his patriotic duty was to kill as many white people as possible because they had driven his people off their kangaroo hunting grounds. Martial law was declared in the settled districts of Van Diemen's Land in November 1828 and was extended to the entire island in October 1830. A "Black Line" of around 2,200 troops and settlers then swept the island with the intention of driving the Aboriginal population from the settled districts. From 1830 to 1834 George Augustus Robinson and Aboriginal ambassadors including Truganini led a series of "Friendly Missions" to the Aboriginal tribes which effectively ended the Black War. Flood states that around 200 settler and 330 Aboriginal Tasmanian deaths in frontier violence were recorded during the period 1803 to 1834, but adds that it will never be known how many Aboriginal deaths went unreported. Clements estimates that colonists killed 600 Aboriginal people in eastern Van Diemen's Land during the Black War. Around 220 Aboriginal Tasmanians were eventually relocated to Flinders Island.As settlers and pastoralists spread into the region of modern Victoria in the 1830s, competition for land and natural resources again sparked conflict with traditional landowners. Aboriginal resistance was so intense that it was not unusual for sheep runs to be abandoned after repeated attacks. Broome estimates that 80 settlers and 1,000–1,500 Aboriginal people died in frontier conflict in Victoria from 1835 to 1853. The growth of the Swan River Colony (centred on Fremantle and Perth) in the 1830s led to conflict with a number of clans of the Noongar people. Governor Sterling established a mounted police force in 1834 and in October that year he led a mixed force of soldiers, mounted police and civilians in a punitive expedition against the
