A solid piece, definitely better suited for research purposes than leisure reading. I have used it for both, and it's certainly well-researched and succinct. Unfortunately that means reading it outside of using it for reference and fact-checking does expose the fact that the writing can be rather dry, bringing to mind school textbooks rather than standard non-fiction.
Still, it does the job, and it's always good to see books about such specific historical events. It's a solid work of local history and a good contribution to the wider narrative of Irish history, and benefits from first-hand interviews and sources -- something that will soon be a thing of the past, if it isn't already. The book also benefits from several pages of photographs, which were utterly fascinating, and is illustrated throughout with relevant maps. It also has an impressive list of appendices.
