The map printed above is a document of the highest importance, for it enables us to detect the real policy, first of Bulgaria, and next of the other Balkan States. This map is an exact translation and reproduction of the map which is to be found on p. 56 of the historical part of a book published in Bulgarian at Sofia and called: _The Soldier’s Companion_, _Manual for the Soldiers of all arms_. This is an official work of propaganda in the army, and therefore in the whole Bulgarian people, since all Bulgarians go through the ranks; and it was published in obedience to order No. 76 of March 14th, 1907, issued by the Bulgarian Ministry of War, approved and authorized by the Chief of the Headquarters Staff of the Bulgarian army. This manual has been recommended by the Bulgarian Ministry of War, in circular No. 28 of March 21st, 1907. Hence we are confronted with an official Bulgarian book dating from 1907, which proves very clearly beyond the possibility of dispute the ideas which have been systematically instilled into the whole Bulgarian people for at least nine years. In this map, entitled Great Bulgaria, which is coloured in the eighth edition of the Bulgarian original, the part said to be “already set free by the Bulgarians” is coloured pink (represented by large hatchings on our map), and the parts said to be “not set free by the Bulgarians” are coloured red (represented by closer hatchings on our map). This official Bulgarian document helps us to understand, both what happened in the Balkan wars, and the conduct of the government of Sofia during the European war. In fact, when in 1912 the Bulgarians entered into an alliance with the Greeks and Serbians against Turkey, they were not even then true to their Allies. At that time they had a very low opinion of the Greeks and Serbians as soldiers. But they thought it very expedient to employ the forces of these nations against the principal enemy, Turkey, intending afterwards to settle accounts with their temporary allies by means of the increase of power which they expected to gain at the expense of Turkey. As these intentions were suspected at Belgrade and Athens, it may easily be conceived that from the very beginning of their joint action the Greek and Serbian governments did not repose full confidence in that of Sofia. The distrust of the Greeks and Serbians was, moreover, thoroughly aroused when King Ferdinand, before he allowed his troops to hurl themselves against the lines of Chataldja, disclosed his claim to enter Constantinople, with the evident intention of staying there if he could. Given the Bulgarian claims in the west, which are set forth in our map, we can further explain why in 1913 the Bulgarians, whose character is hard and unyielding, refused all compromise when the Serbians, excluded by Europe from the Adriatic, demanded from the Bulgarians an equitable compensation to the south of Uskub.
