Guerilla Days in Ireland is the extraordinary story of the fight between two unequal forces, which ended in the withdrawal of the British from twenty-six counties.

Seven weeks before the truce to the Anglo-Irish War of July, 1921, the British presence in County Cork consisted of 8,800 front line infantry troops, 1,150 Black & Tan soldiers, 540 Auxiliaries, 2,080 machine gun corps, artillery and other units; a total of over 12,500 men.

Against these British forces stood the Irish Republican Army whose Flying Columns never exceeded 310 riflemen in the whole of County Cork.
