Irish Convicts Launch Castle Hill Rebellion
In the British penal colony of New South Wales, Australia, many Irish convicts transported after the 1798 Rebellion of the United Irishmen harbored grievances against colonial authorities. On the evening of March 4, 1804, a signal fire set by convict John Cavenagh at Castle Hill Government Farm alerted around 300 mostly Irish rebels to begin their escape and uprising. Led by veterans including Philip Cunningham, the group aimed to seize arms, march on Parramatta, and ultimately sail to Ireland or secure freedom. Martial law was declared across the colony in response. The poorly armed rebels were pursued by colonial troops under Major George Johnston. The main confrontation occurred the following day at Rouse Hill, where the uprising was quickly suppressed.
