as before, and its complete economic strangulation would be rendered inevitable and rapid.  Bulgaria for its own part naturally refused to waive its claim to central Macedonia, well knowing that the master of the Vardar valley is master of the Balkan peninsula.  The first repercussion of the ephemeral treaty of London of May 30, 1913, which created Albania and shut out Serbia from the Adriatic, was, therefore, as the diplomacy of the Germanic powers had all along intended it should be, the beginning of a feud between Greece and Serbia on the one hand, and Bulgaria on the other, the disruption of the Balkan League and the salvation, for the ultimate benefit of Germany, of what was left of Turkey in Europe.

The dispute as to the exact division of the conquered territory in Macedonia between Serbia and Bulgaria had, as arranged, been referred to arbitration, and, the Tsar of Russia having been chosen as judge, the matter was being threshed out in St. Petersburg during June 1913.  Meanwhile Bulgaria, determined to make good its claim to the chestnuts which Greece and Serbia had pulled out of the Turkish fire, was secretly collecting troops along its temporary south-western frontier[1] with the object, in approved Germanic fashion, of suddenly invading and occupying all Macedonia, and, by the presentation of an irrevocable fait accompli, of relieving the arbitrator of his invidious duties or at any rate assisting him in the task.

On the other hand, the relations between Bulgaria and its two allies had been noticeably growing worse ever since January 1913; Bulgaria felt aggrieved that, in spite of its great sacrifices, it had not been able to occupy so much territory as Greece and Serbia, and the fact that Adrianople was taken with Serbian help did not improve the feeling between the two Slav nations.  The growth of Bulgarian animosity put Greece and Serbia on their guard, and, well knowing the direction which an eventual attack would take, these two countries on June 2, 1913, signed a military convention and made all the necessary dispositions for resisting any aggression on Bulgaria’s part.  At one o’clock in the morning of June 30 the Bulgarians, without provocation, without declaration of war, and without warning, crossed the Bregalnica (a tributary of the Vardar) and attacked the Serbs.  A most violent battle ensued which lasted for several days; at some points the Bulgarians, thanks to the suddenness of their offensive, were temporarily successful, but gradually the Serbs regained the upper hand and by July 1 the Bulgarians were beaten.  The losses were very heavy on both sides, but the final issue was a complete triumph for the Serbian army.  Slivnitsa was avenged by the battle of the Bregalnica, just as Kosovo was by that of Kumanovo.  After
