In February 1921 Moore was one of a flying column of over 20 IRA men billeted in an old farmhouse at Clonmult, near Midleton under Commandant Diarmuid Hurley.
They were tracked down and surrounded by a company of the Hampshire Regiment of the British Army and RIC, Black and Tans and Auxiliaries.
Seven of them later had their sentences commuted but two, Moore and his lifelong friend Paddy O'Sullivan were executed by hanging Victoria Barracks, Cork on 28 April 1921.
