Then were revealed the prodigious consequences of complete victory at sea, which were more immediate, more decisive, more far-reaching, more irrevocable than on land. The sea became during the continuance of the war the territory of Great Britain, the open highway along which her ships could pass, while it was closed to the ships of her adversaries. Across that secure sea a small army was sent to Spain to assist the national and heroic, though miserably organised, resistance made by the Spanish people against the French attempt at conquest. The British Government had at last found the right direction for such military force as it possessed. Sir John Moore's army brought Napoleon with a great force into the field, but it was able to retire to its own territory, the sea. The army under Wellington, handled with splendid judgment, had to wait long for its opportunity, which came when Napoleon with the Grand Army had plunged into the vast expanse of Russia. Wellington, marching from victory to victory, was then able to produce upon the general course of the war an effect out of all proportion to the strength of the force which he commanded or of that which directly opposed him. While France was engaged in her great continental struggle England was reaping, all over the world, the fruits of her naval victories. Of the colonies of her enemies she took as many as she wanted, though at the peace she returned most of them to their former owners. Of the world's trade she obtained something like a monopoly. The nineteenth century saw the British colonies grow up into so many nations and the British administration of India become a great empire. These developments are now seen to have been possible only through the security due to the fact that Great Britain, during the first half of the nineteenth century, had the only navy worth considering in the world, and that during the second half its strength greatly preponderated over that of any of the new navies which had been built or were building. No wonder that when in 1888 the American observer, Captain Mahan, published his volume "The Influence of Sea Power upon History," other nations besides the British read from that book the lesson that victory at sea carried with it a prosperity, an influence, and a greatness obtainable by no other means. It was natural for Englishmen to draw the moral which was slumbering in the national consciousness that England's independence, her empire, and her greatness depended upon her sea power. But it was equally natural that other nations should draw a different moral and should ask themselves why this tremendous prize, the primacy of nations and the first place in the world, should for ever belong to the inhabitants of a small island, a mere appendage to the continent of Europe.
