The great strength of this book is its criticism of the analysis and reporting of Peter Hart, who made controversial claims with regard to (a) the Kilmichael ambush of November 28 1920, and (b) the killing of loyalists in violation of a Truce amnesty in April 1922. Ryan's command of source material, and her access to Tom Barry's papers, suggested that Hart had made many claims that could not stand up to scrutiny. Ryan tends to be very careful in her approach, and does not conclude without evidence. A lesson for academic historians and for students of Irish history. A good companion volume, which examines how sophisticated British propaganda then continues to affect history writing, is Brian P Murphy's 'The Origin and Organisation of British Propaganda in Ireland in 1920'.
