The ambassadorial conference at London then directed its attention exclusively to settling the status of Albania. After more than a month of acrimonious discussion a settlement was reached on March 26th in which the principle of nationality which had been invoked to justify the creation of an independent Albania was quietly ignored. The conference agreed upon the northern and northeastern boundaries of Albania. In order to carry her point that Scutari must be Albanian, Austria-Hungary agreed that the almost exclusively Albanian towns of Ipek, Djakova, Prizrend, and Dibra should go to the Serbs. On April 1st King Nicholas was notified that the powers had unanimously agreed to blockade his coast if he did not raise the siege of Scutari. His answer was that the proposed action of the powers was a breach of neutrality and that Montenegro would not alter her attitude until she had signed a treaty of peace. At once the warships of all the powers save Russia (which had none in the Mediterranean) engaged in the blockade. On April 15th, owing to the pressure of the powers and to the strained relations that had arisen between Servia and Bulgaria, the Servian troops were recalled from Scutari. Nevertheless the Montenegrins persisted alone and Scutari fell April 22, 1913. Two days later the Austro-Hungarian government demanded that vigorous action be undertaken by the powers to put independent Albania in possession of Scutari according to the agreement of March 26th. At once the greatest excitement prevailed throughout Russia. Street demonstrations against the Austro-Hungarian policy were held in many of the large cities. In Austria-Hungary military preparations became active on a large scale, and on May 1st the Dual Monarchy gave notice that it would undertake individual action should Montenegro not agree to the ultimatum. Italy, which is determined never to permit the Dual Monarchy individual action in Albania, announced that she would support her ally. As the result of all the pressure brought to bear upon him, on May 5th, King Nicholas yielded and placed Scutari in the hands of the powers, just in time, as Sir Edward Grey informed the English House of Commons, to prevent an outbreak of hostilities between Austria-Hungary and Russia. While the chancelleries of the great powers were thus straining every nerve to agree upon the status of Albania and thereby to prevent a conflict between the two powers most vitally interested, the war between the allies and Turkey was prosecuted during March with greater vigor and with more definite results. On March 5th, Janina surrendered to the Greeks and on March 26th Adrianople fell. The powers had already offered to mediate between the belligerents, and their good offices had been accepted by both sides. The allies at first insisted upon the Rodosto-Malatra line as the western boundary of Turkey, but were informed that the powers would not consent to giving Bulgaria a foothold on the Dardanelles.
