 Major uprisings of the rebellion only occurred in Ulster, Wicklow and Wexford, a county in the province of Leinster.For several months prior to May 1798, Wicklow and many other areas of the country had been subject to martial law which had been imposed in an effort to prevent the long threatened rebellion.The campaign extended against the military itself as some corps of yeomen and militia, especially those with Catholic members, were suspected as United Irish infiltrators who had joined to get training and arms.
