In 1942, he participated in an IRA ambush on a Royal Ulster Constabulary (RUC) patrol but was himself shot, arrested and sentenced to eight years' imprisonment. Adams's maternal great-grandfather, Michael Hannaway, was also a member of the IRB during its bombing campaign in England in the 1860s and 1870s.
