Castle Hill convict rebellion
The Castle Hill rebellion of 1804 was a convict rebellion in the Castle Hill area of Sydney, against the colonial authorities of the British colony of New South Wales. The rebellion culminated in a battle fought between convicts and the colonial forces of Australia, on 5 March 1804 at Rouse Hill. It was dubbed the Second Battle of Vinegar Hill after the first Battle of Vinegar Hill, which had taken place in 1798 in Ireland. The incident was the first major convict uprising in Australian history to be suppressed under martial law.
