in mind so he decided to:

to call it a war.

There were many reprisals by the British -some examples:
The killing of two RIC constables –Patrick Carey and James Burke –in an ambush
at Newtown Darcy, about three miles from Tuam, on 19 July 1920 resulted in a
police reprisal in the early hours of the following morning that saw indiscriminate
firing and widespread looting and burning of property in Tuam town, Go.

republican lord mayor of Cork. Imprisoned in August on
charges of treason, MacSwiney embarked on a hunger
