Service History


  • January: Regiment raised.
  • March: Siege of ManorHamilton


  • April: Attack on ManorHamilton (under Taaffe)?


  • July 8th: Sligo taken. Regiment destroyed?


O' Connor may have lost command of the regiment for a period in 1643 when his arrest was ordered over his involvement in the Sligo Gaol massacre. He appears to have been back in command by 1645. The Regiment may have passed to Col Luke Taaffe during this period.
