When this agreement was signed, the dissolution of Austria-Hungary was not in contemplation, or at least, if it was considered, the possibility of its accomplishment seemed very remote. It was assumed that the Dalmatian territory to be acquired under the treaty to be negotiated in accordance with the terms of the Pact would, with the return of the Italian provinces, give to Italy naval control over the Adriatic Sea and secure the harborless eastern coast of the Italian peninsula against future hostile attack by the Austro-Hungarian Empire. The boundary laid down in the agreement was essentially strategic and based primarily on considerations of Italian national safety. As long as the Empire existed as a Great Power the boundary of the Pact of London, so far as it related to the Adriatic littoral and islands, was not unreasonable or the territorial demands excessive.
But the close of active warfare in the autumn of 1918, when the armistice went into effect, found conditions wholly different from those upon which these territorial demands had been predicated. The Austro-Hungarian Empire had fallen to pieces beyond the hope of becoming again one of the Great Powers. The various nationalities, which had long been restless and unhappy under the rule of the Hapsburgs, threw off the imperial yoke, proclaimed their independence, and sought the recognition and protection of the Allies. The Poles of the Empire joined their brethren of the Polish provinces of Russia and Prussia in the resurrection of their ancient nation; Bohemia, Moravia, and Slovakia united in forming the new state of Czecho-Slovakia; the southern Slavs of Croatia, Slavonia, Bosnia, Herzegovina, and Dalmatia announced their union with their kindred of the Kingdom of Serbia; and Hungary declared the severance of her political union with Austria. In a word the Dual Empire ceased to exist. It was no longer a menace to the national safety of Italy. This was the state of affairs when the delegates to the Peace Conference began to assemble at Paris.
The Italian statesmen realized that these new conditions might raise serious questions as to certain territorial cessions which would come to Italy under the terms of the Pact of London, because their strategic necessity had disappeared with the dissolution of Austria-Hungary. While they had every reason to assume that Great Britain and France would live up to their agreement, it was hardly to be expected that under the changed conditions and in the circumstances attending the negotiation and signature of the Pact, the British and French statesmen would be disposed to protest against modifications of the proposed boundary if the United States and other nations, not parties to the agreement, should insist upon changes as a matter of justice to the new state of the Serbs, Croats, and Slovenes. It apparently was considered expedient, by the Italian representatives, in view of the situation which had developed, to increase rather than to reduce their claims along the Dalmatian coast in order that they might have something which could be surrendered in a compromise without giving up the boundaries laid down in the Pact of London.
It is probable, too, that these additional claims were advanced by Italy in order to offset in a measure the claims of the Jugo-Slavs, who through the Serbian delegates at Paris were making territorial demands which the Italians declared to be extravagant and which, if granted, would materially reduce the proposed cessions to Italy under the Pact of London. Furthermore, the Italian Government appeared to be by no means pleased with the idea of a Jugo-Slav state so strong that it might become a commercial, if not a naval, rival of Italy in the Adriatic. The Italian delegates in private interviews showed great bitterness toward the Slavs, who, they declared, had, as Austrian subjects, waged war against Italy and taken part in the cruel and wanton acts attendant upon the invasion of the northern Italian provinces. They asserted that it was unjust to permit these people, by merely changing their allegiance after defeat, to escape punishment for the outrages which they had committed against Italians and actually to profit by being vanquished. This antipathy to the Slavs of the former Empire was in a measure transferred to the Serbs, who were naturally sympathetic with their kinsmen and who were also ambitious to build up a strong Slav state with a large territory and with commercial facilities on the Adriatic coast which would be ample to meet the trade needs of the interior.
While there may have been a certain fear for the national safety of Italy in having as a neighbor a Slav state with a large and virile population, extensive resources, and opportunity to become a naval power in the Mediterranean, the real cause of apprehension seemed to be that the new nation would become a commercial rival of Italy in the Adriatic and prevent her from securing the exclusive control of the trade which her people coveted and which the complete victory over Austria-Hungary appeared to assure to them.
The two principal ports having extensive facilities for shipping and rail-transportation to and from the Danubian provinces of the Dual Empire were Trieste and Fiume. The other Dalmatian ports were small and without possibilities of extensive development, while the precipitous mountain barrier between the coast and the interior which rose almost from the water-line rendered railway construction from an engineering standpoint impracticable if not impossible. It was apparent that, if Italy could obtain both the port of Trieste and the port of Fiume, the two available outlets for foreign trade to the territories lying north and east of the Adriatic Sea, she would have a substantial monopoly of the sea-borne commerce of the Dalmatian coast and its hinterland. It was equally apparent that Italian possession of the two ports would place the new Slav state at a great disadvantage commercially, as the principal volume of its exports and imports would have to pass through a port in the hands of a trade rival which could, in case of controversy or in order to check competition, be closed to Slav ships and goods on this or that pretext, even if the new state found it practicable to maintain a merchant marine under an agreement granting it the use of the port.
In view of the new conditions which had thus arisen through the dissolution of the Austro-Hungarian Empire and the union of the Southern Slavs, the Italian delegates at Paris began a vigorous campaign to obtain sovereignty, or at least administrative control, over Fiume and the adjacent coasts and islands, it having been generally conceded that Trieste should be ceded to Italy. The Italian demand for Fiume had become real instead of artificial. This campaign was conducted by means of personal interviews with the representatives of the principal Powers, and particularly with those of the United States because it was apparently felt that the chief opposition to the demand would come from that quarter, since the President was known to favor the general proposition that every nation should have free access to the sea and, if possible, a seaport under its own sovereignty.
The Italian delegates were undoubtedly encouraged by some Americans to believe that, while the President had not actually declared in favor of Italian control of Fiume, he was sympathetic to the idea and would ultimately assent to it just as he had in the case of the cession to Italy of the Tyrol with its Austrian population. Convinced by these assurances of success the Italian leaders began a nationwide propaganda at home for the purpose of arousing a strong public sentiment for the acquisition of the port. This propaganda was begun, it would seem, for two reasons, first, the political advantage to be gained when it was announced that Signor Orlando and his colleagues at Paris had succeeded in having their demand recognized, and, second, the possibility of influencing the President to a speedy decision by exhibiting the intensity and unity of the Italian national spirit in demanding the annexation of the little city, the major part of the population of which was asserted to be of Italian blood.
The idea, which was industriously circulated throughout Italy, that Fiume was an Italian city, aroused the feelings of the people more than any political or economic argument could have done. The fact that the suburbs, which were really as much a part of the municipality as the area within the city proper, were inhabited largely by Jugo-Slavs was ignored, ridiculed, or denied. That the Jugo-Slavs undoubtedly exceeded in numbers the Italians in the community when it was treated as a whole made no difference to the propagandists who asserted that Fiume was Italian. They clamored for its annexation on the ground of "self-determination," though refusing to accept that principle as applicable to the inhabitants of the Austrian Tyrol and failing to raise any question in regard to it in the case of the port of Danzig. The Italian orators and press were not disturbed by the inconsistency of their positions, and the Italian statesmen at Paris, when their attention was called to it, replied that the cases were not the same, an assertion which it would have been difficult to establish with facts or support with convincing arguments.
While the propaganda went forward in Italy with increasing energy, additional assurances, I was informed by one of the Italian group, were given to Signor Orlando and Baron Sonnino that President Wilson was almost on the point of conceding the justice of the Italian claim to Fiume. It was not until the latter part of March, 1919, that these statesmen began to suspect that they had been misinformed and that the influence of their American friends was not as powerful with Mr. Wilson as they had been led to believe. It was an unpleasant awakening. They were placed in a difficult position. Too late to calm the inflamed temper of the Italian people the Italian leaders at Paris had no alternative but to press their demands with greater vigor since the failure to obtain Fiume meant almost inevitable disaster to the Orlando Ministry.
