In 1906 Gen. Grierson was on the General Staff at the War Office and Col. Barnardiston was military attache at Brussels. In view of the solemn guarantee given by Great Britain to protect the neutrality of Belgium against violation from any side some academic discussions may, through the instrumentality of Col. Barnardiston, have taken place between Gen. Grierson and the Belgian military authorities as to what assistance the British Army might be able to afford to Belgium should one of her neighbors violate that neutrality. Some notes with reference to the subject may exist in the archives at Brussels. It should be noted that the date mentioned, namely 1906, was the year following that in which Germany had, as in 1911, adopted a threatening attitude toward France with regard to Morocco and in view of the apprehensions existing of an attack on France through Belgium it was natural that possible eventualities should be discussed. The impossibility of Belgium having been a party to any agreement of the nature indicated or to any design for violation of Belgian neutrality is clearly shown by reiterated declarations that she has made for many years past that she would resist to the utmost any violation of her neutrality from whatever quarter and in whatever form such violation might come. It is worthy of attention that these charges of aggressive designs on the part of other powers are made by Germany who, since 1906, has established an elaborate network of strategical railways leading from the Rhine to the Belgian frontier through a barren, thinly populated tract, deliberately constructed to permit of the sudden attack upon Belgium which was carried out two months ago. * * * * * REPLY TO GREAT BRITAIN. Statement by Count von Bernstorff, German Ambassador, Washington, Oct. 15. Concerning the Anglo-Belgian military agreement existing since 1906, a formal denial has been issued by England, which proves nothing. The documents are in the hands of the German authorities, and will be published in full. The facts remain that a so-called "neutral" country concluded a military agreement with England, which provided for landing of British troops in this "neutral" country. The document proves that by its own free will "neutral Belgium" accepted the British offer and decided to fight on the side of the Allies. England instigated Belgium to go to war, and when the time came to protect the unfortunate little country it was left to its own resources. Germany, on the other hand, which had heard of Belgium's agreement with England at the beginning of this war, offered to protect Belgium and to pay full indemnity for all her losses. Germany would have religiously kept her promise. The documents found in Brussels further prove that as far back as 1906 England was systematically trying to bring about the coalition which has now forced war on Germany. * * * * * GRAY BOOK'S TESTIMONY.
