But this arrangement between Greece and Servia would leave no territory for Bulgaria in Central and Western Macedonia! Yet Servia had solemnly bound herself by treaty not to ask for any Turkish territory below the Ochrida-Golema Vreh line. There was no {75} similar treaty with Greece, but Bulgaria regarded the northern frontier of New Greece as a matter for adjustment between the two governments. Servia, withdrawn behind the Ochrida-Golema Vreh line in accordance with the terms of the treaty, would at any rate have nothing to say about the matter. And, although the Bulgarian government never communicated, officially or unofficially, its own views to Greece or Servia, I believe we should not make much mistake in asserting that a line drawn from Ochrida to Saloniki (which Bulgaria in spite of the Greek occupation continued to claim) would roughly represent the limit of its voluntary concession. Now if you imagine a base line drawn from Saloniki to Goletna Vreh, you have an equilateral triangle resting on Ochrida as apex. And this equilateral triangle represents approximately what Bulgaria claimed in the western half of Macedonia as her own. The war between the Allies was fought over the possession of this triangle. The larger {76} portion of it had in the war against Turkey been occupied by the forces of Servia; and the nation, inflamed by the military spirit of the army, had made up its mind that, treaty or no treaty, it should not be evacuated. On the south, especially above Vodena, the Greeks had occupied a section of the fatal triangle. And the two governments had decided that they would not tolerate the driving of a Bulgarian wedge between New Servia and New Greece. Bulgaria, on the other hand, was inexorable in her demands on Servia for the fulfilment of the terms of the Treaty of Partition. At the same time she worried the Greek government about the future of Saloniki, and that at a time when the Greek people were criticizing Mr. Venizelos for having allowed the Bulgarians to occupy regions in Macedonia and Thrace inhabited by Greeks, notably Seres, Drama, and Kavala, and the adjacent country between the Struma and the Mesta. These were additional causes of dissension between the Allies. But the primary {77} disruptive force was the attraction, the incompatible attraction, exerted on them all by that central Macedonian triangle whose apex rested on the ruins of Czar Samuel's palace at Ochrida and whose base extended from Saloniki to Golema Vreh. THE CLAIM OF BULGARIA From that base line to the Black Sea nearly all European Turkey (with the exception of the Chalcidician Peninsula, including Saloniki and its hinterland) had been occupied by the military forces of Bulgaria. Why then was Bulgaria so insistent on getting beyond that base line, crossing the Vardar, and possessing herself of Central Macedonia up to Ochrida and the eastern frontier of Albania?
