The Piltown Cross ambush, an action of the Irish War of Independence, took place near Kinsalebeg County Waterford on the night of 1 November 1920. Involved was the IRA West Waterford Brigade, specifically the newly formed Deise Flying Column under O/C George Lennon of Dungarvan, as well as Volunteers from the local Ardmore battalion. Returned Great War veteran John Riordan helped plan the engagement involving a feint attack on the RIC barracks in Ardmore. The British garrison in Youghal subsequently despatched nearly twenty troops in a single lorry. They were ambushed at Kinsalebeg and suffered two dead and six wounded. The ambush resulted in the capture of several rifles and a large quantity of ammunition which were used to equip the flying column. Captured were R.I.C. constables O'Neill
