Irish Royalist foot ending up massacred at Drogheda

Service History


  • August: Battle of Rathmines (in reserve)
  • September: Besieged at Drogheda
  • September: Massacred at Drogheda


The regiment appears to be comprised of both Catholic and Protestant Royalists in 1649, perhaps recruited from the Parliamentarian defenders of Dundalk and Drogheda recently taken by Inchiquin. They fought in Ormonde's Royalist army at Rathmines, though they were in reserve and not heavily engaged. Subsequently they were sent to garrison Drogheda and were massacred there after Cromwell's storm of the city.
