The recriminations between Greeks and Bulgarians were quite as bitter. There had been no preliminary agreement as to the division of conquered territory between them, and this permitted each to indulge in the most extravagant claims. The great bone of contention was the possession of the fine port of Salonika. As soon as the war against Turkey broke out, both states pushed forward troops to occupy that city. The Greeks arrived first and were still in possession. Moreover, they maintained that, except for the Jews, the population is chiefly Greek. So are the trade and the schools. M. Venezelos, the Greek prime minister, insisted also that the erection of an independent Albania deprived Greece of a large part of northern Epirus, as it had deprived Servia of a great part of Old Servia, and Montenegro of Scutari. In fact, he asserted that Bulgaria alone would retain everything she hoped for, securing nearly three-fifths of the conquered territory, and leaving only two-fifths to be divided among her three allies; and this, despite the fact that but for the activity of the Greek navy in preventing the convoy of Turkey's best troops from Asia, Bulgaria would never have had her rapid success at the beginning of the war. Finally, he strenuously objected to the whole seaboard of Macedonia going to Bulgaria, as the population where it was not Moslem was chiefly Greek. All the parties to the dispute made much of ethnical and historical claims—"A thousand years are as a day" in their sight. The answer of Dr. Daneff to the Greek demands was to the effect that Greece already had one good port on the Mediterranean, while Bulgaria had none, and that Bulgaria would have to spend immense sums on either Kavala or Dedeagatch to make them of any great value. Moreover, as a result of the war, Greece would get Crete, the Aegean islands, and a good slice of the mainland. She had suffered least in the war and was really being overpaid for her services.
Behind all these formal contentions were the conflicting ambitions and the racial hatreds which no discussion could effectually resolve. Bulgaria was determined to secure the hegemony of the Balkan peninsula. She believed that her role was that of a Balkan Prussia, and her great victories made her confident of her ability to play the role successfully. To this Servia would never consent. The Servians far outnumber the Bulgarians. Were they united under one scepter they would be the strongest nation in the Balkans. Their policy is to maintain an equilibrium in the peninsula until the hoped-for annexation of Bosnia and Herzegovina will give them the preponderance. This alone would incline Servia to make common cause with Greece. In addition, she had the powerful motive of direct self-interest. Since she did not secure the coveted territory on the Adriatic, Salonika would be more than ever the natural outlet for her products. Should Bulgaria wedge in behind Greece at Salonika, Servia would have two Powers to deal with, each of which could pursue the policy of destroying her commerce by a prohibitory tariff, a policy so often adopted toward her by Austria-Hungary. M. Pashitch, therefore, was determined to have the new southern boundary of Servia coterminous with the northern boundary of Greece. Moreover, Greeks and Servians were aware of the relative weakness of the Bulgarians due to their great losses and to the wide territory occupied by their troops. The war party was in the ascendant in each country. The Servians were anxious to avenge Slivnitza, and the Greeks still further to redeem themselves from the reputation of 1897. Had peace been signed in January, there is little doubt that a greater spirit of conciliation would have prevailed. The Young Turks were universally condemned at that time for refusing to yield; but had they deliberately adopted Abdul Hamid's policy of playing off one people against another, they could not have succeeded better than by their determination to fight.
Even before the fall of Adrianople, on March 26th, military conflicts had taken place between Bulgarians and Servians and between Bulgarians and Greeks. On March 12th a pitched battle occurred between the latter at Nigrita; and though a mixed commission at once drew up a code of regulations for use in towns occupied by joint armies, not the slightest attention was subsequently paid to it. The Servians shortly afterward expelled the manager of the branch of the National Bulgarian Bank at Monastir, a step which drew forth emphatic protests from Sofia against the policy of Serbizing districts in anticipation of the final settlement. On April 17th, M. Pashitch informed Bulgaria that the Government would refuse to be bound by the terms of the preliminary treaty of March, 1912. From that date until the signing of the treaty of peace with Turkey on May 31st, the recent allies carried on an unofficial war, which consisted of combats of extermination marked by inhuman rage. After that event each of the combatants strained every nerve to push forward its armies and to possess new territories, while each continued to accuse the other of violating every principle of international law.
The ambassadors of the great Powers at the capitals of the Balkan States made urgent representations to the Balkan Governments to restrain their armies, but without effect. On June 10th the Servian Government dispatched a note to Sofia demanding a categorical answer to the Servian demand for a revision of the preliminary treaty. On July 11th the Czar telegraphed to King Peter and King Ferdinand appealing to them to avoid a fratricidal war, reminding them of his position as arbitrator under the preliminary treaty and warning them that he would hold responsible whichever state appealed to force. "The state which begins war will be responsible before the Slav cause." This well-meant action had an effect the opposite of that hoped for. In Vienna it was looked upon as an indirect assertion of moral guardianship by Russia over the Slav world. The Austrian press insisted that the Balkan states were of age and could take care of themselves. If not, it was for Europe, not for Russia, to control them. The political horizon grew still darker when one week later Dr. Daneff answered the Servian note in the negative. This resulted in the Servian Minister withdrawing from Sofia on June 22d.
What was the plan of campaign and the degree of preparedness of the principal belligerent in the second Balkan war which was about to commence? The plan of the Bulgarians was the only one whereby they could hope to secure victory. It depended for success upon surprizing the Servians by sending masses of Bulgarian troops into the home territory of Servia by way of the passes leading directly from Sofia westward through the mountains. This would cut off the Servian armies operating in Macedonia from their base of supplies and require their immediate recall for the defense of the home territory. It was an operation attended by almost insurmountable obstacles. The major part of the Bulgarian army was in eastern Thrace and would have to be brought across a country unprovided with either railroads or sufficient highways. Moreover, the army would have to rely for the transport of provisions and equipment upon slow-moving bullock wagons. Nevertheless, given time, secrecy, and freedom from interference, the aim might be attained. The necessary divisions of the army were set in motion in the beginning of May. So successful were the Bulgarians in keeping secret the route and the progress of the army, that by the middle of June they confidently looked forward to success. Their high hopes were destroyed by the evil diplomacy of Dr. Daneff in his relations with Roumania.
