For strategical reasons Germany determined to attack France through Belgium, declaring that the international treaty which bound her to respect Belgian neutrality was but a "Scrap of Paper." Great Britain, as one of the signatories to the treaty, protested against such a violation of good faith, but finding protestation vain declared war upon Germany on 4 August 1914. The whole Empire solidly supported the Mother Country and shared valiantly in all her achievements. THE RALLY OF THE EMPIRE Important as were the offers of help, both of men and provisions, which the self-governing Dominions and the Indian Empire made to the Mother Country almost immediately after the outbreak of the war, the knowledge that these great daughter-nations were morally convinced of the justice of the British cause, was a factor of even more far-reaching importance. Great as was the necessity of organizing and expanding the Imperial forces, and thus creating an extra army or armies to reinforce the British Expeditionary Force in France, urgent as was the need of taking advantage of the prompt offers of help which came from all parts of the Empire, the necessity of convincing the self-governing Dominions and the Empire at large of the righteousness of the cause for which Great Britain was fighting was more imperative still. For in the long run the consciousness of the justice of the principles for which a people is fighting, alone can ensure the massing of material force sufficient to secure material victory. Evidence that the case for Great Britain was fully understood and thoroughly approved, not only by our own peoples, but by the bulk of the neutral States of the world, was not long in presenting itself. The Dominions as a whole had satisfied themselves that the British cause was just, before Sir Edward Grey had made it plain by his speech of August 3rd that the British Government had done everything short of sacrificing the honour of the country to avoid war. In the words of Sir Richard McBride, the Premier of British Columbia, "Should it unfortunately develop that Great Britain is compelled to engage in hostilities, Canada will automatically be at war also"; while in Australia, Mr. Fisher, the ex-Prime Minister, declared, "Should honour demand the Mother Country to take part in hostilities, Australians will stand beside her to the last man and the last shilling." These sentiments found expression in the offers of help of men and material, which have been described in the preceding chapter. To those offers the King replied by a message to the Overseas Dominions: "I desire to express to my people of the Overseas Dominions with what appreciation and pride I have received the messages from their respective Governments during the last few days. "These spontaneous assurances of their fullest support recall to me the generous, self-sacrificing help given by them in the past to the Mother Country.
