From 1918 to 1922 Michael Collins kept working diaries of his busy revolutionary life. They are a collection of hurried notes, necessary lists, names and appointments, things to do, and things not done. They are a record of his long working days, and they got him to where he needed to be on time. Though these diaries do not contain conventional lengthy entries in which Collins finally reveals his innermost thoughts, they still tell us much about this extraordinary man. In this book, Michael Collins’s biographers, Anne Dolan and William Murphy, capture the nature of this new Collins source. They reflect on how the diaries change what we know about him, and challenge us to think differently about his life. The diaries begin with Collins a revolutionary among many; they end in 1922 with Collins as the most powerful figure in Ireland. They begin with Collins a single man; they end with him about to be married. The authors present thematic reflections on what the diaries reveal of his transformed life. As they are also the diaries of his everyday life, the book examines very particular episodes, the curious and ordinary entries, which allow us to see Collins from new angles. Rather than offering the final piece that will solve the Collins puzzle, the diaries pose new questions to be asked.
