By 1912, Greece, Bulgaria, Serbia, and Montenegro had contrived, in spite of any past quarrels, in spite of the mutual jealousies even then being displayed in the recurring Macedonian massacres, of Christians by Christians as well as by Turks, to arrive at a sufficient degree of unity to allow them to make war jointly on Turkey. Bulgaria and Serbia concluded an offensive and defensive alliance, arranging for all contingencies and providing for the division of the spoils which it was hoped to win from the Turks. Between Bulgaria and Greece there was no such definite alliance, but a military convention only. The division of the spoil after the war was left to future determination, both Greek and Bulgarian probably having it clearly in his head that he would have all his own way after the war or fight the issue out subsequently. A later Punch cartoon put this peculiarity of a Balkan alliance with pretty satire. Greece and Serbia were discussing what they should do with the spoils they were then winning from Bulgaria. "Of course we shall fight for them. Are we not allies?" said one of the partners. I was through the war of 1912 as war correspondent for the London _Morning Post_, and followed the fortunes of the main Bulgarian army in the Thracian campaign. In this book I do not intend to attempt a history of the war but will give some impressions of it which, whilst not neglecting any of the chief facts in any part of the theatre of operations, will naturally be mainly based on observations with the Bulgarians. First, with regard to the political side of the war, one could not but be struck by the exceedingly careful preparation that the Bulgarians had made for the struggle. It was no unexpected or sudden war. They had known for some time that war was inevitable, having made up their minds for a considerable time that the wrongs of their fellow-nationals in Macedonia and Thrace would have to be righted by force of arms. Attempts on the part of the Powers to enforce reforms in the Christian Provinces of Turkey had, in the opinion of the Bulgars, been absolute failures, and they had done their best to make them failures, wishing for a destroyed Turkey not a reformed Turkey. In their opinion there was nothing to hope for except armed intervention on their part against Turkey. And, believing that, they had made most careful preparation extending over several years for the struggle. That preparation was in every sense admirable. For instance, it had extended, so far as I could gather, from informants in Bulgaria, to this degree: that they formed military camps in winter for the training of their troops. Thus they did not train solely in the most favourable time of the year for manœuvres, but in the unfavourable weather too, in case that time should prove the best for their war. The excellence of their artillery arm, and the proof of the scientific training of their officers, prove to what extent their training beforehand had gone.
