On 7 June Harvey resigned at Sliabh Coillte , disgusted with his defeat and the ensuing Scullabogue Barn massacre . He was replaced as Commander-in-Chief by Philip Roche and returned to Wexford where he was appointed President of the town committee . Confident that a treaty would be negotiated on the rebels behalf by Lord Kingsborough , the captured loyalist commander of the North Cork Militia , he retired to his family home at Bargy Castle . Shortly afterwards he and John Henry Colclough , dressed as peasants , travelled to a cave on the Greater Saltee Island from whence they planned to escape to republican France . They were , however , betrayed and Harvey was arrested by Ralph James , an officer of the Irish Yeomanry , and brought to Wexford town . He was tried , convicted and hanged on Wexford bridge on 28 June 1798 . His body was afterwards beheaded , the trunk thrown into the River Slaney and the head displayed on a spike on the courthouse . His corpse was recovered by his friends and buried in Mayglass cemetery , near Mountpleasant House , the house he lived in before he died . He was unmarried and succeeded by his brother James , who recovered the attainted family estates 12 years later
