During the month of January, 1916, the southern theatre of war was comparatively quiet. The forces under General Cadorna maintained their offensive on the Isonzo without any decisive revolt taking place. There was considerable bombardment of the bridgeheads at Tolmino and Gorizia. In the Gorizia sector the Austrians attacked the Italian positions at Oslavia, capturing 900 men and inflicting severe losses in killed and wounded. Determined attacks by the Italian troops followed, and the positions were again transferred to Italian hands. At the end of this month an official resume covering Italy's entrance into the war and the operations of the Italian army in the intervening months was issued at Rome. In this official communique it was estimated that 30,000 Austrian prisoners, 5 guns, 65 machine guns, and a large quantity of war material had so far been captured by the Italians from the Austrian forces. Twenty-five Austrian divisions, totaling about 425,000 men, were said to have been massed along the Italian frontier at the beginning of the war. CHAPTER XLIX MOVE AGAINST GERMANY A royal decree was issued at Rome on February 11, 1916, prohibiting the importation into Italy or transit through Italy of all German and Austrian merchandise, as well as the exportation of all merchandise of German or Austrian origin through Italian ports. This was the formal recognition of a policy that had been followed out with increasing strictness since hostilities commenced, but which had never been officially declared. The declaration of war by Italy against Austria carried with it the prohibition of trading with Austro-Hungarian subjects, and announcement had been made in the Italian press of prosecution of persons on the charge of trading with the nation's enemy. The coupling of the German Empire with Austria-Hungary in this royal decree was the first formal act on the part of Italy in the way of making it clear that all commercial relations with Germany were suspended. This was in accordance with the general policy of cooperation among the Allies, whose disjointed action had hitherto seriously hampered the conduct of the war.
