Thirdly, that the element of chance, which every wise and prudent reasoner will very largely admit into all military affairs, worked in favour of the Revolution in the critical moments of the early wars. The reader who could make closer acquaintance with this aspect of Mr. Belloc's work, and it is an aspect, as has been said, of capital importance, need only turn to the too few pages of _The French Revolution_, where he will find ample evidence not only of Mr. Belloc's understanding of the importance of military history, but of his vast knowledge of military science; and the same may be said of those little books Mr. Belloc has published from time to time on some of the outstanding battles of the past, such as _Blenheim_, _Malplaquet_, _Waterloo_, _Cressy_ and _Tourcoing_. It is apparent, then, that Mr. Belloc brings to a task which the mass of the English public is quite incapable of undertaking for itself peculiar advantages, in that he has combined with a long and careful study of military history a thorough technical knowledge of military science. In addition to this major and essential qualification he possesses, as the outcome of his pursuits and experience, other minor and subsidiary though still very necessary qualifications. In this war, as in all wars of the past, the lie of country and the fatigue of men are two of the weightiest factors; and Mr. Belloc is enormously assisted in attempting a nice appreciation of these factors by the knowledge acquired in the long pursuit of his topographical tastes and by his practical experience in the ranks of the French army. On this latter point too much insistence should not be laid, though to ignore it entirely would be as foolish as to exaggerate its importance. We may best assess its value, perhaps, by saying that Mr. Belloc has been in possession for more than twenty years of certain definite knowledge which the vast majority of Englishmen have only acquired in the past year. More than twenty years ago he learnt the elementary rules of military organization and the ordinary facts of army life which are common knowledge in conscript countries. In England we have remained ignorant of these facts. Many of us have learnt them for the first time since August, 1914; many of us, though we have come to a consciousness of them, will never learn them. In a passage in _A General Sketch of the European War_, in which Mr. Belloc exposes "the fundamental contrast between the modern German military temper and the age-long traditions of the French service," though he brings into play much information that he has doubtless acquired in more recent years, we can see shining through, the memory of early experiences.
