Professor Morgan, whose bright little book, called “Sketches From the Front,” has given to us some of the most fresh and vivid pictures of the actualities of warfare in France, presents in the present volume the evidence he has been busy in collecting regarding the behaviour of the German troops in the western theatre of war. Some of this has already been made known to the public by what he published in the _Nineteenth Century and After_ in June, 1915, and also by the depositions which he obtained under the instructions of the Home Office and submitted to the British Committee on Alleged German Outrages. (Many of these were published in the Appendix to their Report last May.) Since that time he has spent four or five months in collecting further important data and still more months in collating the results of the facts he has collected, having been granted by the British Headquarters Staff in France those facilities for moving to and fro along the front and getting into touch with eye-witnesses which were essential for arriving directly at the facts. The evidence thus obtained is supplemented by several diaries of German soldiers never before published in England, and by some extracts from documents issued by the Russian Government describing cruelties committed by the Germans in the fighting on the Eastern front. As respects the data he has himself collected, Professor Morgan explains, in his introduction, the methods he has followed in taking evidence and testing its value, showing himself sensible, as a lawyer ought to be, of the need for care and caution in such a matter. The large experience which his months of work at the front have given him adds weight to his assurance that what he submits is worthy of all credence as well as to the conclusions at which he has arrived. But before adverting to these conclusions a preliminary question deserves to be considered. It has been asked--and it is natural that it should he asked--“What is the use of multiplying tales of horror?” “Why do anything that can aggravate the bitterness of feeling, already lamentably acute, between the belligerent nations? All war is horrible; why add fresh items to the list of offences which are making us think worse of human nature than we supposed two years ago we ever could think?” These questions need an answer. Such a painful record as the present book contains, such a record as can be found in the reports already officially published by the Belgian, French, and British Governments, might, perhaps, have been better left unpublished if it did not serve some definite tangible aim, looking to some permanent good for mankind.
