A British military convoy of Black and Tans and including a Royal Irish Constabulary Sergeant named Michael Hickey, sets off from Dungarvan Castle on the night of March 18, heading east for the coastal village of Clonea. Their goal that night is the arrest of Irish Republican Army (IRA) volunteer John Murphy, who has been involved in gun running between Clonmel, County Tipperary, and Dungarvan.
Irish Republican Army volunteers of the West Waterford flying column have plans that night to demolish Tarr’s Bridge over the Colligan River between Dungarvan and the Abbeyside. However, when they receive word of the British convoy heading east out of Dungarvan, a last-minute action is organized by the Active Service Unit (ASU) to intercept it on its way back to Dungarvan.
The IRA volunteers ambush the convoy at the Burgery, about a mile and a half northeast of Dungarvan. In overall command of the IRA unit is IRA General Headquarters (GHQ) Officer George Plunkett. Also present are West Waterford Brigade Commandant Pax Whelan, Active Service Unit (ASU) leader George Lennon, and Mick Mansfield.
A British Crossley tender is set on fire and prisoners are taken by the IRA, including Sergeant Hickey. Early on the morning of March 19, Hickey is executed by an IRA firing squad with a sign reading “police spy” affixed to his tunic. Hickey is later buried in an unmarked grave. Other prisoners, including Captain DV Thomas, the commander of the British garrison, are released.
After the ambush, a group of volunteers under Plunkett return to search for any armaments left behind by the British forces. Crown forces who are now searching the area engage the IRA party. IRA volunteers Seán Fitzgerald and Pat Keating are shot dead. Constable Sydney R. Redman, a Black and Tan, is shot dead during the return fire.
