Question: George Johnston was a key figure in putting down what rebellion by convicts against colonial authority in the Castle Hill area of the British colony of New South Wales?

<P0-S0>  The rebellion culminated in a battle fought between convicts and the colonial forces of Australia on 5 March 1804 at Rouse Hill, dubbed the Second Battle of Vinegar Hill after the first Battle of Vinegar Hill which had taken place in 1798 in Ireland. <P0-S1> The Castle Hill rebellion of 1804 was a rebellion by convicts against colonial authority in the Castle Hill area of the British colony of New South Wales. <P0-S2>  It was the first and only major convict uprising in Australian history suppressed under martial law. <SEP> <P1-S0>  After serving as a young marine officer in the American Revolutionary War, Johnston served in the East Indies, fighting against the French, before volunteering to accompany the First Fleet to New South Wales. <P1-S1> Lieutenant-Colonel George Johnston (19 March 1764 – 5 January 1823) was briefly Lieutenant-Governor of New South Wales, Australia after leading the rebellion later known as the Rum Rebellion. <P1-S2>  After serving as adjutant to Governor Arthur Phillip, Johnston served in the New South Wales Corps and he was later a key figure in putting down the Castle Hill convict rebellion in 1804 and then the Rum Rebellion in 1808, the latter of which led to his court martial and subsequent cashiering from military service. <P1-S3>  In his later life, he returned to New South Wales as a private citizen, raising a family in the colony and establishing a successful farm around Annandale in Sydney. <SEP> <P2-S0> The history of New South Wales refers to the history of the state of New South Wales and the area's preceding Indigenous and British colonial societies. <P2-S1>  The Mungo Lake remains indicate occupation of parts of the New South Wales area by Indigenous Australians for at least 40,000 years. <P2-S2>  The English navigator James Cook became the first European to map the coast in 1770 and a First Fleet of British convicts followed to establish a penal colony at Sydney in 1788. <P2-S3>  The colony established an autonomous Parliamentary democracy from the 1840s and became a state of the Commonwealth of Australia in 1901 following a vote to Federate with the other British colonies of Australia. <P2-S4>  Through the 20th century, the state was a major destination for an increasingly diverse collection of migrants from many nations. <P2-S5>  In the 21st century, the state is the most populous in Australia, and its capital, Sydney is a major financial capital and host to international cultural and economic events. <SEP> <P3-S0> Annandale Farm was situated six kilometres from Sydney in the present day suburbs of Stanmore and Annandale. <P3-S1>  Built by George Johnston, it became one of the most successful farms in the early colonial days of New South Wales. <P3-S2>  Johnston was a Royal Marines officer, and briefly Lieutenant-Governor of New South Wales. <P3-S3>  He was a key figure in the Rum Rebellion of 1808. <P3-S4>  He rode from the farm to arrest Captain Bligh on January 26, 1808. <P3-S5>  Also it was from the farm where Johnston marched with his troops to Castle Hill on March 5th, 1804 to quell a convict revolt.
