Britain had no great military force to throw into the balance, such as the armies of France and Russia. Her small regular army was little more than a garrison for her Oversea Dominions, and her Territorial Force was intended for home defence. But Lord Haldane, when Secretary for War, had foreseen the possibility of a Continental struggle, and had prepared plans by which an Expeditionary Force of about 100,000 men could be placed on the Continent of Europe in a very short time. This force was, for its size, probably the most expert army in the world. It took its place on the left of the French line, and, though small in comparison with the mighty levy of France, it was fated to play a leading part in the first decisive battles.
Behind the regular army was our second line of defence, the Territorials, nominally 300,000 strong. But it was very certain that as soon as war was declared the whole manhood of Britain would be called upon, and that many hundreds of thousands of young men would be eager to serve. Lord Kitchener was appointed Secretary for War, and under his direction recruiting began. Before Christmas nearly two millions of our men were under arms.
But Britain's main weapon was her navy, which was by far the strongest in the world. After that came her wealth and her great manufacturing capacity, by which she could supply the munitions of war required both for her own forces and for those of her allies. If her navy could dominate the seas, then her commerce would go on as before, while that of Germany would cease, and her troops and those of her allies could be moved about the world at her pleasure. "He who commands the sea," as Francis Bacon said long ago, "hath great freedom."
Germany was prepared for a war which she had always foreseen, and had the greater strength; but if the Allies did not suffer an early defeat, their strength was certain to grow with every month, while that of Germany must decline. But if the Allies were thus to grow in power they must be able to maintain free communications with the outer world and with one another, and for this they must rely on the supremacy of the British fleet.
In the very first days of war events happened which proved that the German Emperor was right in dreading the entry of Britain into the struggle. The British Empire overseas awoke to action like a strong man from slumber, and there began an epic of service which was to grow in power and majesty up to the last hour of the campaign. No man can read without emotion the tale of those early days in August, when from every quarter of the globe there poured in appeals for the right to share in Britain's struggle.
