Of the actual operations along the Montenegrin front not so much detailed information is available as there is of the other sections of the theatre of war. War correspondents were not allowed to accompany either army in this field and the only reports so far given out, covering this period, are from the few official bulletins issued by the two respective governments and from other more indirect sources. On August 3, when the Austrians had already begun bombarding Belgrade, King Nicholas signed an order for the mobilization of his forces, and four days later, on August 7, he declared war against Austria. But already the Austrians had detached an army corps under General Ermoly to prevent any possible juncture between the Serbian and Montenegrin forces. For the time being, therefore, until the Serbians had driven back the first Austrian invasion, the Montenegrins facing this division of the Austrian army acted on the defensive. This, however, with the advantageous nature of the country, did not require the full strength of the Montenegrin army; part of it, therefore, was employed in an attack on the Austrian towns situated on the narrow strip of Austrian territory running along the sea coast. The chief of these, Cattaro, was subjected to a hot bombardment from the heavy guns on Mt. Lovcen, commanding that section of the coast. A few days later, on August 10, the Montenegrin infantry descended from the surrounding heights and delivered a strong assault on Spizza and Budua. The activity of Austrian warships, which bombarded Antivari, where Montenegro touched the coast, made it impossible for the Montenegrins to hold what they had taken. Another force, however, turned toward Scutari and occupied that town. Mt. Lovcen continued, not only then, but at intervals for the next year, to pour a heavy artillery fire on Cattaro, and its environs. In Bosnia, over toward the Serbian operations, fighting had already begun and continued until the Serbians drove the main Austrian army back. On August 20, just as the Serbians were delivering their last attack on Shabatz and the Austrians were stampeding across the Drina, the Montenegrins delivered a heavy attack along their whole front, causing the Austrians to retire in that section as well. The following day the Austrians, in trying to recover their lost ground, brought up more mountain artillery, then advanced their infantry up against the Montenegrin entrenchments. Here occurred the first hand-to-hand fighting, the Austrians charging with their bayonets again and again, but they were finally repulsed again with heavy loss. From now on the Montenegrins, under the command of General Vukotitch, who had so distinguished himself in the Balkan War, gradually assumed an offensive and advanced into Bosnia. On September 2 he again encountered the Austrians at Bilek, and succeeded in defeating them after a heavy fight, in which a comparatively large number of prisoners were taken.
