At 19:55 on 21 November (scarcely 20 minutes before the first bomb had exploded), five men from Northern Ireland—Patrick Hill, Gerard Hunter, Richard McIlkenny, William Power and John Walker—had boarded a train at Birmingham New Street station. These men—who, alongside Hugh Callaghan, would become known as the "Birmingham Six"—were originally from Northern Ireland. Five of the Birmingham Six hailed from Belfast, whereas John Walker had lived in Derry until age 16. All six men had lived in Birmingham for between 11 and 27 years respectively and, although they had known James McDade and/or his family to varying degrees, each man was adamant they had not known of his IRA affiliations.
