Rather different, perhaps, is the case of another territory lost by Bulgaria at the treaty of Bucharest, and which she has again failed to recover--the Southern Dobrudja. Apart from the one city of Silistria (with 14,000 people), this small territory would seem to be of little value to anybody. It contains, however, over 100,000 Bulgarians as against only 6000 Roumanians; moreover, it is of strategic importance. Roumania’s motive for demanding it in 1913 was to protect the railway leading to her chief port, Constanza, a line which was at one point only about twenty miles from the old Bulgarian frontier. But through the cession then made, the danger was merely shifted to the other side. It is now Bulgaria’s chief Black Sea port, Varna, and the railway serving it that are menaced, for the Roumanian frontier comes within about ten miles of them. Hence the American delegation at Paris endeavored to have the frontier of 1913 corrected so that neither side would be in danger. But Roumania displayed a certain obstinacy, and the Conference, not wishing to complicate much more serious questions then pending between it and Roumania, shelved the Dobrudja matter, intimating, however, that it might be taken up later in connection with the problem of Bessarabia. Not only has Bulgaria failed to regain her losses of 1913, but the new Peace Treaty deprives her of some bits of territory that have hitherto belonged to her. Serbia has secured some small rectifications of the frontier established in 1913, all of them for strategic reasons. One of them, in the valley of the River Strumica, was very genuinely needed, for at that point the old frontier came within about six miles of the Belgrade-Salonica railway, and what this means is shown by the fact that in the first year of the Great War, before Bulgaria officially entered the contest, this all-important railroad was almost cut by a raid of Bulgarian _komitadjis_. The other chief rectification, in the Pirot-Tsaribrod basin, seems more questionable, and has the disadvantage of bringing the frontier even nearer to Sofia than has been the case since 1878. A more considerable loss to Bulgaria, though not necessarily a definitive one, is that of the territory in Western Thrace which she acquired in 1913. To this question I shall come back in a moment in connection with the whole problem of Thrace. As a preliminary to that, however, it seems necessary to say a word as to the general situation and claims of Greece. * * * * * While the Balkan settlement now being effected at Paris is in the main a confirmation of that of 1913, some new departures have been made or are in prospect; and these relate almost wholly to the problem of Greek irredentism. For if Roumanian or Serbian national unity could be attained chiefly by the acquisition of former Austrian and Hungarian territories, the question of Greek national unity involves primarily further changes of territory in the Balkans.
