Book excerpt: In the 1940s and 1950s Ernie O'Malley interviewed survivors of Ireland's struggle for independence. These interviews, now being made available to the public for the first time, give a fascinating insight into the times and the people who fought. The West Cork interviews detail IRA intervention in Ulster, as well as giving prominence to the Cork No. 5 Brigade. Of eight interview subjects, five participated in the IRA's invasion of Northern Ireland. The interviewees talk about the Republican rifle exchange with the National Army which occurred secretly in May 1922, as Free State rifles supplied by Britain were swapped with IRA rifles, which were then sent to arm the IRA in Ulster. They also document the gruesome torture of Brigade Commander Ted O'Sullivan.
