SEAMUS COSTELLO exhibited a greatness of the same order as James Connolly.
His energy, his intelligence, accuracy and thoroughness, his humour, quickness, and decisiveness, made him an outstanding mind and personality in his generation of Irishmen. He was both a thinker and a man of action.
Seamus Costello – like James Connolly in his day – was the single greatest threat to British imperialist interests in Ireland.
