The archduke proceeded to the Town Hall, and after berating the city officials listened to the speeches of welcome. As he and his wife were departing a Serbian student, named Prinzip, who was later arrested, rushed out from the crowd and fired point-blank at the couple with a revolver. Both were hit a number of times and died some hours later from their wounds. Great excitement immediately prevailed in Sofia and Vienna, and in Berlin and St. Petersburg to a lesser degree. What retribution would Austria demand? The Austrian press openly avowed that the plot on the archduke's life had been hatched in official circles in Serbia, and the Austrian Government made no attempt to suppress these statements. One hour after the tragedy had taken place it had assumed an official and international complexion. A punitive war against Serbia was immediately urged in Vienna. On June 29, 1914, anti-Serbian riots broke out in Bosnia, Sarajevo was put under martial law, and the bodies of the assassinated couple began the mournful journey to Vienna. On July 2, 1914, Prinzip confessed that he had apprised the Pan-Serbian Union of his attempt to kill the archduke, and on the same day the first intimation came that the matter was considered a serious one in Germany--the kaiser became "diplomatically ill." Then, for twenty days there was an outward calm in the capitals of Europe, but behind the scenes the diplomats were at work; the great question was how far Russia would go in defending her Slavic sister state against the impending demands of Austria. These demands were made public in a note which Austria sent to Serbia on July 23, 1914. Serbia was given till 6 p. m., July 25, 1914, to comply with the ultimatum, which read as follows: "On March 31, 1909, the Royal Serbian Minister in Vienna, on the instructions of the Serbian Government, made the following statements to the Imperial and Royal Government: "'Serbia recognizes that the _fait accompli_ regarding Bosnia has not affected her rights, and consequently she will conform to the decisions that the powers will take in conformity with Article XXV of the Treaty of Berlin. At the same time that Serbia submits to the advice of the powers she undertakes to renounce the attitude of protest and opposition which she has adopted since October last. She undertakes on the other hand to modify the direction of her policy with regard to Austria-Hungary and to live in future on good neighborly terms with the latter.' "The history of recent years, and in particular the painful events on June 28 last, have shown the existence in Serbia of subversive movement with the object of detaching a part of Austria-Hungary from the monarchy. The movement which had its birth under the eyes of the Serbian Government, has had consequences on both sides of the Serbian frontier in the shape of acts of terrorism and a series of outrages and murders.
