At the commencement of the year 1804, the tranquillity of the colony experienced some interruption. I have mentioned in the beginning of this chapter the circumstances of the importation of Irish convicts in the year 1800, and of their attempts to disseminate amongst their fellow-prisoners the seeds of insubordination and riot. The vigilance and prudence of Governor Hunter, at that time, checked the rapid progress of the flame of sedition; but, although apparently extinguished, the fire was only smothered for a time. Discontent had taken root, and its eradication was a matter of more difficulty than could have been foreseen. The most unprincipled of the convicts had cherished the vile principles of their new companions, and only waited for the maturity of their designs to commence the execution of schemes which involved the happiness and security of the whole colony. The operations of these disaffected persons had hitherto been conducted with such secrecy, that no suspicion of their views was entertained, until the 4th of March in this year, when a violent insurrection broke out at Castle Hill, a settlement between Parramatta and Hawkesbury, and the insurgents expressed their determination to emancipate themselves from their confinement, or to perish in the struggle for liberty. Information of the extent and alarming appearance of this mutiny having reached the governor, it was deemed necessary, on the following day, to proclaim martial law; and a party of the troops, under the command of Lieutenant-Colonel George Johnston, were directed to pursue the rebels. After a long march, the military detachment came up with the insurgents, near the Ponds, about half-way between Parramatta and Hawkesbury, and a short parley ensued, when the Colonel found it necessary to fire upon them; and, after killing several of the misguided rebels, and making prisoners of the principals who survived, the remainder made a rapid retreat. Ten of the leaders of this insurrection, who had been observed as particularly conspicuous and zealous in their endeavours to seduce the rest, were tried on the 8th of March, and capitally convicted. Three were executed on the same evening at Parramatta, since it was justly concluded, that measures of prompt severity would have a greater effect upon the minds of those who had forsaken their allegiance. On the following day, two other rebels were executed at Sydney, and three at Castle Hill: the two remaining criminals were respited, as they were the least corrupted, and had discovered symptoms of sincere remorse for the part which they had taken in the late operations. On the 9th, martial law was repealed; and from that moment no disturbance has again broken in upon the peace of the settlement of a serious nature, although it would be too much to suppose that the seeds of insubordination and disorder were entirely eradicated by the frustrated event of the first endeavour. Men of such desperate
