This book covers, in ten chapters, the use of railways in war from Balaklava to the present day. Essentially, the deployment and supply of millions of soldiers in the wars of the last century would have been impossible without railways. The book is written in good English throughout and has a very useful index.
The author is very definitely a railway author rather than a military one or a master of both subjects. He mainly relies on AJP Taylor for the political/military viewpoint. It is a shame he was not more catholic in his reading, both for the wider perspective and because of the book's main failing, the paucity and inadequacy of maps. Military books normally have much better maps than this.
Let us take WWI as an example. For the Western front (over one chapter is devoted to this), there is one map, situated a long way from the relevant text. To follow the action, the author naturally uses a number of place names, the majority of which are not marked on his map. There is an inset, barely legible, of the area of the Somme, which is one of the very few places in the book where a map is inessential since the Somme offensive is only discussed in very general terms.
To accompany the chapter on WWI's several Eastern fronts, there are no maps at all. I found it necessary to improvise - for instance, the account of the Arabian/Palestine campaign can be followed with the aid of a map in Natkiel and Pimlott's excellent "Atlas of Warfare".
The author rightly criticises some of the combatants in his book, for rushing into action without adequate preparation. I wonder if the same criticism might not be fairly levelled at him.
