In the meantime, the Balkans again became the seat of trouble. You will recall that Bulgaria, who had grown proud because of her victory over Turkey in the war of 1912, was too grasping when it came to a division of the conquered territory. Thus she brought on a second war, in the course of which Greece and Serbia defeated her, while Roumania took a slice of her territory and the Turks recaptured the city of Adrianople. The czar of Russia had done his best to prevent this second Balkan war, even sending a personal telegram to Czar Ferdinand of Bulgaria and to King Peter of Serbia, begging them for the sake of the Slavic race, not to let their quarrels come to blows. Bulgaria, confident of her ability to defeat Greece and Serbia, had disregarded the Russians’ pleadings, and as a result Russia did not interfere to save her when her neighbors were robbing her of part of the land which she had taken from Turkey. It will be recalled that Macedonia was the country which Bulgaria had felt most sorry to lose, as its inhabitants were largely Bulgarian in their blood, although many Greeks and Serbs were among them. Therefore, just as Italy strove by war and diplomacy to add Trentino to her nation, so Bulgaria now saw her chance to gain Macedonia from Serbia. Accordingly, she asked the four great powers what they would give her in case she entered the war on their side, and attacked Turkey by way of Constantinople, while the French and English were hammering at the forts along the Dardanelles.[7] [7] England and France needed wheat, which Russia had in great quantities at her ports on the Black Sea. On the other hand France and England, by supplying Russia with rifles and ammunition, could strike a hard blow at Germany. The four powers, after much persuasion and brow-beating, finally induced Serbia to agree to give up part of Serbian Macedonia to Bulgaria. They further promised Bulgaria to give her the city of Adrianople and the territory around it which Turkey had reconquered. But Bulgaria was not easily satisfied. She wanted more than Serbia was willing to give; she wanted, too, the port of Kavala, which Greece had taken from her. This the allies could not promise. In the meantime, Bulgaria was bargaining with Austria, Germany, and Turkey. France, England, and Russia were ready to pay back Serbia for the loss of Macedonia, by promising her Bosnia and Herzegovina in case they won the war from Austria. In like fashion, Austria and Germany promised Bulgaria some Turkish territory and also the southern part of the present kingdom of Serbia, in case she entered the war on their side.
