The Society for Army Historical Research 2015 Christmas Book List

This well researched, objective, and not unsympathetic account of a complex individual who was by turns courageous, kind, brutal and repellent, sheds light on both Irish and Great War history. It deserves a wide readership.

The Irish Sword Summer 2016

Charles Messenger, with his trademark diligence in seeking and marshalling sources, has produced a rounded account of this most controversial figure. It is unlikely to be surpassed as the baseline source on the subject.

Society of Friends of the National Army Museum

Charles Messenger has crafted a genuinely interesting and invigorating examination of a man whose military service spanned colonial actions in Africa, the Western Front and the Troubles in Ireland. Messenger's research is, as always, meticulous and impressive in its range and depth.
It succeeds on multiple levels; it provides a thorough examination of Crozier's verifiable past and the military context in which he existed, whilst also showing that historical research is rarely as easy as it appears. Crozier's unreliability is a major part of his character. Messenger never hides from this and allows the verifiable facts to allow Crozier's protean nature to shine through.

US Journal of Military History

An interesting and easily accessible biography that utilises an impressive array of archival documents.

History Ireland

Forget the warts, Broken Sword a fascinating boils and all biography of a unique Divisional Commander of a strange driven character. Frank Croziers career, in all but his genuine moral and physical bravery, was both Flashmanesque and fascinating.

Western Front Association

In this excellent book, Charles Messenger summarises the often controversial Crozier as a mixture of good and bad, a plausible rogue "admired by some, with a scant regard for the truth". Read about his command with 119 Brigade and judge for yourself.

Bulletin - Military Historical Society

The author has done a fine job rescuing this interesting and controversial, flawed figure, Crozier - considered a fine 'front line commander' of the Great War - from relative obscurity. The reader of this volume will gain a greater appreciation of the human element of leadership in combat, and will enjoy reading this absorbing account as much as the author seemingly enjoyed writing it.

International Bibliography of Military History

Author Charles Messenger is both an ex soldier and well established military writer. His skills as a writer and researcher into the obscure depths of a highly complicated career - and the duplicitous and complexity post war politics in which Crozier became involved - is fascinating. He seeks to sort fact from fiction about the mans career.
