The Irish Rebellion of 1798, which lasted several months, was the culmination of thwarted plans and uprisings conducted by The Society of United Irishmen founded in 1791 and the Catholic resistance group known as the Defenders. They had sought help from Britain's then enemy France as early as 1796 in an attempt to bring about democratic reform and Catholic emancipation. In December of 1796 a force of 15,000 French troops arrived off the coast at Bantry Bay, but storms prevented their landing. By 1798 the Order had been heavily infiltrated by government informers and a round up of their leaders, including Lord Edward Fitzgerald took place in May of that year. This forced the hand of the Society and the rebellion was launched without French assistance. Heavy military presence in Dublin prevented any action there, but a number of uprisings took place in the surrounding counties. The rebellion spread but strong military reinforcements kept the rebels in check. Even the arrival of two French forces, on 8 September and 12 October were not enough to maintain the momentum. By the end of the year all but a number of small guerilla groups had been crushed.
