The Battle of Carlow took place in Carlow town, Ireland on 25 May 1798 when Carlow rebels rose in support of the 1798 rebellion which had begun the day before in County Kildare. The United Irish organisation in Carlow led by a young brogue-maker named Mick Heydon who had taken over the leadership following the arrest of the previous leader, Peter Ivers, who was arrested with several other leading United Irishmen at Oliver Bond's house in March of that year, had assembled on the night of the 24th and set off at dawn to attack the county town. Picking up more volunteers along the way, their numbers swelled to around 1,200 they marched completely unopposed.
