Major George Johnston, 1810

Major George Johnston was in charge of the New South Wales Corps during the Castle Hill Rebellion of 1804. His troops successfully put down the rebellion. In 1808 Johnston himself was involved in a rebellion. He became lieutenant-governor of New South Wales after helping to depose Governor William Bligh. The so-called Rum Rebellion was the first and only time in Australian history that military force has been used to overthrow a government.
