Apart from this concession to popular prejudice, the Coalition was an advantage from the national though not from the Premier's personal or party point of view. He would have been wiser in his own interests to have resigned and left the responsibility to men whose supporters believed that with a little more energy and foresight the war could be won in a few months or at most a year. Few had as yet realized that the struggle was one between mighty nations which only the perseverance of peoples, and not the merits of Ministers, could decide; and the inevitable deferment of foolish hopes would sooner or later have produced a reaction in favour of the retiring Premier and his party. But it would have been accompanied by a revival of party warfare which would have undoubtedly weakened national unity and impaired the prospects of success; and all parties to the Coalition--Liberal, Unionist, and Labour--were patriotically inspired when they agreed to share a burden which the wiser among their leaders foresaw would tax their united strength. There was need enough for unity during the summer of 1915 when the Allied offensive in the West had broken down, little progress was being made in the Dardanelles, and the Germans were driving the Russians like chaff before them. The one gleam of light was the intervention of Italy, which might distract Austrian forces from the Galician front and in any case meant some accession of strength to the Allied cause. Italy had already rendered inestimable services to the Entente by proclaiming that Germany's action was offensive in character, and therefore dispensed Italy from an obligation to support her partners in the Triple Alliance; and her neutrality during August and intervention in May disproved the gibe of the French diplomatist that she would rush to the rescue of the conqueror. The question throughout the winter was whether she would complete her breach of the Triple Alliance by attacking her former Allies. The grievance upon which diplomacy fixed was the reciprocal compensation which Austria and Italy had promised each other in case either were forced to disturb the status quo in the Balkans. Austria pleaded that her invasion of Serbia involved no permanent disturbance, because no permanent annexation was intended; to which Baron Sonnino retorted that Austria had declared, during the Turkish-Italian war, that an Italian bombardment of the Dardanelles or even the use of searchlights against the Turkish coast would constitute a breach of the agreement. In March Baron Burian accepted the principle that compensation was due to Italy, and discussion arose as to its nature and extent. The Italian Government pressed its advantage, and demanded not only the whole of Italia irredenta, that unredeemed territory peopled by Italians in the Trentino and across the Adriatic, which had been left under Hapsburg dominion after the wars of Italian liberation, but
