Anthony Terence Quincey Stewart, known professionally as A.T.Q. Stewart or Tony Stewart, was a Northern Irish historian, teacher and academic, and a best-selling author on the subject of the politics of Ulster and Northern Ireland.
Tony Stewart's book is a brilliant history of the third home rule crisis with respect to Ulster unionism. Unlike many historians, he was a brilliant writer. Obviously, this work is a bit dated now but it is still highly useful.
Another excellent history by A.T.Q. Stewart which predates his "The Narrow Ground" by ten years. This volume provides a thorough retelling of the events of the political crisis within Ireland brought about by the proposed introduction of home rule by Asquith's pre-war government. The political and (para-)military response from the Opposition under Bonar Law and the unionist population of the north-eastern corner of Ireland are detailed as are the administrative organisation required behind the successful importation of 24,000 rifles in April 1914. Stewart's description of Wilfred Spender's adventures in northern Scotland during this episode as truly Buchanesque as he attempts to locate the armaments' location. The only potential criticism is Tim Bowman's view that Stewart is clearly writing from a Unionist (with a capital U) perspective. Recommended.
