The compact was from the first more honoured in the breach than the observance. Italy undertook to wage war by all means at her disposal in union with France, Great Britain, and Russia against the Powers at war with them. But for another year she remained at peace with Germany. War was, indeed, declared upon Austria on 22 May, but the union with the Allies was limited almost exclusively to the prosecution of Italy's territorial ambitions, and the forces employed hardly produced effects to correspond with the facts that the population of Italy was almost equal to that of France and that the bulk of the Austrian armies were involved in the struggle with Russia. Italy had, indeed, peculiar disadvantages; she was more divided in mind about the war than any of the great protagonists, and the splendid qualities of her Bersaglieri and Alpini were not shared by all her troops. Her war strength was put at a million men, and she still had to cope with Turkish forces in Tripoli which only surrendered at the end of the war as a condition of the armistice concluded between Great Britain and Turkey. She was further hampered by lack of coal and inadequate industrial equipment, and her northern frontier had been so drawn in the Alps as to give Austria every advantage of the passes both for offence and defence. To these drawbacks were added a defective strategy dictated by political idiosyncrasies. The capture of Trieste rather than the defeat of the enemy was made the great objective of the campaign. It had the advantage that it might not involve German troops in its defence, and the defect that it was a divergent operation which even if successful would have no material influence on the general course of the war. Soon, too, it became evident that Trieste was not likely to fall until Austria was defeated on other fields or fell into impotence through domestic disruption (see Map, p. 298).
