It appears to be the custom in the German Army for soldiers to be encouraged to keep diaries and to record in them the chief events of each day. A good many of these diaries were collected on the field when British troops were advancing over ground which had been held by the enemy, were sent to headquarters in France, and dispatched thence to the War Office in England. They passed into the possession of the Prisoners of War Information Bureau, and were handed by it to our secretaries. They have been translated with great care. We have inspected them and are absolutely satisfied of their authenticity. They have thrown important light upon the methods followed in the conduct of the war. In one respect, indeed, they are the most weighty part of the evidence, because they proceed from a hostile source and are not open to any such criticism on the ground of bias as might be applied to Belgian testimony. From time to time references to these diaries will be found in the text of the report. In Appendix B they are set out at greater length both in the German original and in an English translation, together with a few photographs of the more important entries. In Appendix C are set out a number of German proclamations. Most of these are included in the Belgian Report No. VI., which has been furnished to us. Actual specimens of original proclamations issued by or at the bidding of the German military authorities, and posted in the Belgian and French towns mentioned, have been produced to us, and copies thereof are to be found in this appendix. Appendix D contains the rules of The Hague Convention dealing with the conduct of war on land as adopted in 1907, Germany being one of the signatory powers. In Appendix E will be found a selection of statements collected in France by Professor Morgan. These five appendices are contained in a separate volume. In dealing with the evidence we have recognized the importance of testing it severely, and so far as the conditions permit we have followed the principles which are recognized in the courts of England, the British overseas dominions, and the United States. We have also (as already noted) set aside the testimony of any witnesses who did not favorably impress the lawyers who took their depositions, and have rejected hearsay evidence except in cases where hearsay furnished an undersigned confirmation of facts with regard to which we already possessed direct testimony from some other source, or explained in a natural way facts imperfectly narrated or otherwise perplexing.[A]
