By order of The Commissioner of Police of the Metropolis. New Scotland Yard, S. W. The anniversary of Trafalgar Day was celebrated while we were in London. This was one of the most decisive battles in the history of the world. As an English view of the battle of Trafalgar I copy below the editorial from the Daily-Graphic, and might add, in my own words, that but for the British navy our sea-coast cities, both on the Atlantic and Pacific, might easily have been wiped out before this time. TRAFALGAR DAY To-day is the anniversary of one of the most decisive battles in the history of the world. Our minds rest naturally enough on Waterloo as the battle which finally destroyed Napoleon's power in 1815, to the great relief of France, as well as of all the rest of Europe. But it was the battle of Trafalgar, ten years previously, which secured to Great Britain the command of the sea and so prepared the way for Napoleon's downfall. The same factors that operated a century ago are operating today. There has been no Trafalgar to wipe the enemy's ships off the sea, but our sea supremacy was so well secured before the war began that the enemy has only once ventured to challenge it, with disastrous results to himself off the Jutland coast. The effect of British sea supremacy has been felt from the first day of the war. We were able by our intervention at once to prevent Germany from carrying out her scheme of a naval descent on the French coast. The same sea-power has since enabled us to transport in safety armies probably aggregating over two million men to France, the Dardanelles, Egypt, Mesopotamia, Salonica, the Cameroons and German East Africa. The larger portion of these armies has naturally been drawn from the United Kingdom, but large contingents have come from Canada, Australia, India, South Africa and the West Indies. None of these movements of troops would have been possible unless we had secured the command of the sea. In addition, our sea supremacy has enabled us to maintain our commerce with the whole of the world, while blocking German commerce wherever we chose to use our power. The British Navy is the force which has determined the final defeat of Germany, and so long as we maintain that force at adequate strength we can face without flinching any danger that may threaten us from any part of the world.
