Early penal colony Australia’s worst fear came true on March 4, 1804. That night the Irish republican battle cry “Death or Liberty” broke over the bush at Sydney’s western settlement, Castle Hill. Colonial governor Philip Gidley King had expected it, having warned London not to transport more Irish republican prisoners. “I do not know what will be the consequences”, King told the Colonial Office. “They have hitherto kept us in a constant state of suspicion.” King issued a draconian proclamation act which prevented seditious oaths on pain of flogging and denied meetings of more than 12 prisoners without permission. Two meetings in defiance of this law was punishable by death.
That did not stop Irish convicts at the big government-run farms west of Sydney, where they swapped news of Ireland and made plans and weapons. Ireland had simmered since 1798 when the United Irishmen rebellion was brutally down in the decisive battle of Vinegar Hill in County Wexford despite French intervention later that year. Rebels kept up guerrilla warfare in the Wicklow hills first under Joseph Holt, and when he surrendered in November 1798, under Michael Dwyer. Resistance spluttered on until 1803 when Robert Emmet’s Dublin plot was betrayed. Dwyer surrendered in December that year. The revolution had one final epilogue half a world away the following year.
Between 300 to 500 Irish rebels, Holt and Dwyer included, were transported to Sydney where they continued to nurse grievances against the British. They were joined by 200 Irish malcontents who had been transported since 1791 for agrarian crimes of resistance. Irish legal administration against offenders was vindicative, arbitrary and careless, there was no documentation about sentences, and many languished as convicts long after their sentence expired. There were rumours of failed mutinies aboard transport ships adding to the paranoia of Sydney officials. They disdained the Catholic Irish who were, as flogging Protestant parson Samuel Marsden put it, “the most wild, ignorant and savage race that were ever favoured with the light of civilisation.”
The convict Irish sought safety in numbers especially at the Parramatta government farm where they spoke, sung and plotted in Irish and used go-slow tactics against their captors. The leader Holt had privileges and got a land grant, but authorities were still suspicious, especially after he met Scottish Martyrs leader Maurice Margarot. Holt was briefly arrested in 1800 while false rumours of his plotting were investigated. He was freed but many Irish were doubly punished, sent to the fearsome secondary penal station at Norfolk Island where they suffered under sadistic commandants Joseph Foveaux and James Morriset. Two Irishmen were executed in 1800 for planning an uprising on the island.
Tensions rose in Sydney after news of Emmet’s failure in 1803. Holt said plans for a western Sydney uprising were well advanced by 1804. He claimed he was against it and warned plotters that it would lead to the gallows. Planning continued with the support of Margarot and others on the outside. The leader was United Irishman Philip Cunningham who survived Norfolk Island and was now back in Sydney where his stonemason skills were in demand. Born in Kerry around 1770, Cunningham was not involved in the 1798 rebellion but became a key figure in the reorganisation of rebel networks in Munster and Leinster in 1799. He was convicted of sedition at a Clonmel court martial and his death sentence was commuted to transportation for life. He was sent to Norfolk Island for participating in a violent convict mutiny but by 1804 he had returned to Sydney. As overseer of masons at Castle Hill, he led the plotting among 500 mainly Irish convicts.
On March 4, convict John Cavenagh set his hut alight as a signal to start the rebellion. Convicts overpowered the hated floggers and constables and seized muskets, swords, axes and ammunition from nearby farms. Cunningham assembled convicts on Toongabbie’s Constitution Hill and sent columns to collect men and arms for an attack on Parramatta and Sydney. They accumulated around a third of the colony’s armoury. Like in 1798, they occupied the high ground, which they named Vinegar Hill in honour of that rebellion.
The plan was to set fire to Macarthur’s Elizabeth Farm at Parramatta to draw the garrison out and signal to other prisoners to join the rebellion. A messenger named John Griffen turned informant and alerted the Parramatta garrison rather than the convicts at Windsor and the Hawkesbury. The garrison secured the streets and dispatched a rider to inform the governor in Sydney. The Macarthurs and Marsden led civilian evacuations from Parramatta downriver in darkness. Elizabeth Macarthur saw flames at Castle Hill and heard that 300 Irishmen were bearing down on the barracks. Governor King rode to Parramatta on hearing the news and declared a state of rebellion. Major George Johnston led the New South Wales Corp west to face the rebels.
On Constitution Hill, Cunningham was disappointed to find Parramatta had not risen and decided not to attack the barracks. Instead he marched his men towards Windsor where he hoped to link up with prisoners from the Hawkesbury. Johnston’s men caught up with the rebels near Rouse Hill and quickly routed them. Though only 29 soldiers and 50 militia faced 270 rebels, the British had vastly superior firepower. Johnston resorted to deceit to further improve his odds. He rode ahead under a flag of truce to discuss demands with Cunningham who supposedly asked for “death or liberty” and a “ship to take us home.” Johnston put a pistol to Cunningham’s head and ordered his troops to open fire. The ill-trained rebels fled under sustained gunfire. Twenty were killed despite surrendering with another 40 captured. There were no Crown casualties. Cunningham suffered a sword wound and was hanged that night without trial. The Castle Hill rebellion was over.
Johnston was rewarded with a land grant, despite his dishonourable tactics. Though King admitted the rebels had committed no atrocities, his revenge was harsh. Besides Cunningham, eight rebel leaders, some of them English, were sent to the gallows and nine more received severe flogging. Forty other supposed ringleaders including Margarot were sent to secondary penal stations. Holt was also imprisoned, despite his claims of innocence and served 19 months in Norfolk Island.
Castle Hill was the most serious insurrection in settler Australian history. It far dwarfed the later Eureka Stockade rebellion as the relative size of the convict population, compared to free settlers and soldiers, left the government vulnerable if all the prisoners rose. And unlike the 1808 Rum Rebellion against Governor Bligh which left the authority of the crown and the system intact, the Castle Hill rebels rejected both. They paid a heavy penalty for their failure. An upper class Irish convict transported for kidnapping an heiress who arrived in Sydney shortly after the rebellion could “smell the bones and hear the groans of dying patriots.”
Michael Dwyer arrived in Australia in 1806 and missed the rebellion. King was worried his arrival would add “to the number of disaffected of that class already.” Dwyer was closely watched and arrested for supposed plotting. He served two years in Norfolk Island and Van Diemen’s Land. Holt became a landowner in Sydney and was wealthy enough to return to Ireland, which he later regretted.
Most other Irish convicts eventually came to an accommodation with their new land. Dwyer ran a western Sydney pub and became a policeman, rising to chief constable of Liverpool. He was sent to a debtor’s prison when his business collapsed and died of dysentery in 1825. Yet Dwyer showed Irish ambitions to prosper in Australia. The Irish working class brought their solidarity to the workplace, helping found trade unions and the Australian Labor Party. In 1988 ALP hero Gough Whitlam unveiled a monument to the Irish rebels at the probable Rouse Hill site of the Castle Hill rebellion. The unveiling was almost completely ignored by national media and unlike the mythology surrounding Eureka, Castle Hill remains a mostly forgotten part of Australian history. Though the final act of the 1798-1903 rebellion, it is also sadly ignored in Ireland.
