was apparently favourable to the action proposed by the Entente, which offered great possibilities of success, inasmuch as the Austrians had only a small body of troops in Croatia, it was not strong enough to resist the influence of the secret societies, who placed their veto on any action in co-operation with Italy.[4] The full details of this affair are not quite clear, but one thing is certain, and that is that owing to Serbia’s inaction Austria was able to withdraw five out of the six divisions which were left on the Save and send them to the Italian front. At that period of the war the Serbian front was considered in the Austrian Army almost as a rest camp. In the autumn of 1915 the Serbian _débâcle_ took place, caused chiefly by the Bulgarian attack. The intervention of Turkey on the side of the Central Empires had rendered Bulgaria’s position extremely difficult, but that was not the chief reason of the latter’s intervention. Bulgaria had remained profoundly dissatisfied with the results of the Peace of Bucarest (1913), which brought the Turko-Balkan War to an end and deprived her of a great part of the fruits of her victory against the Turks. The fault was to a large extent her own, because she had attacked her ex-Allies, Serbia and Greece, and had been completely defeated by them; she then lost not only the whole of Macedonia, to conquer which she had entered the war, but also Eastern Thrace, with Adrianople and Kirk-Kilisse, which were reoccupied by the Turks when the Bulgarian Army had been beaten by the Serbs and Greeks, and a part of Dobrugia which had belonged to her since the creation of the Bulgarian State in 1878, and had been annexed by Roumania, who had intervened in the war at the last moment. This left a bitter feeling of spite in the soul of the Bulgarians, and sowed the seeds of a future war of revenge.
