In 1767, an attempt to revive the plot was made by the Munster oligarchy, without success. Dr. McKenna, Bishop of Cloyne, was arrested but enlarged; Mr. Nagle, of Garnavilla (a relative of Edmund Burke), Mr. Robert Keating, and several respectable Catholic gentlemen, were also arrested. It appears that Edmund Burke was charged by the ascendancy party with having "sent his brother Richard, recorder of Bristol, and Mr. Nagle, a relation, on a mission to Munster, to levy money on the Popish body for the use of the Whiteboys, who were exclusively Papists." The fact was, that Burke did originate a subscription for the defence of the second batch of victims, who, through his and other exertions, were fortunately saved from the fate of their predecessors.
Contemporaneous with the Whiteboys were the northern agrarians, called "Hearts of Steel," formed among the absentee Lord Downshire's tenants, in 1762; the "Oak Boys," so called from wearing oak leaves in their hats; and the "Peep o' Day Boys," the precursors of the Orange Association. The infection of conspiracy ran through all Ireland, and the disorder was neither short-lived nor trivial. Right-boys, Defenders, and a dozen other denominations descended from the same evil genius, whoever he was, that first introduced the system of signs, and passwords, and midnight meetings, among the peasantry of Ireland. The celebrated society of United Irishmen was the highest form which that principle, in our politics, ever reached. In its origin, it was mainly a Protestant organization.
From the first, the Catholic bishops and clergy strenuously opposed these secret societies. The Bishop of Cloyne issued a reprobatory pastoral; Father Arthur O'Leary employed his facile pen against them; the Bishop of Ossory anathematized them in his diocese. Priests in Kildare, Kilkenny, and Munster, were often in personal danger from these midnight legislators; their chapels had been frequently nailed up, and their bishops had been often obliged to remove them from one neighbourhood to another to prevent worse consequences. The infatuation was not to be stayed; the evil was engrafted on society, and many a long year, and woeful scene, and blighted life, and broken heart, was to signalize the perpetuation of secret societies among the population.
