Then followed the most brilliant piece of sea strategy in the war. Two battle-cruisers were sent secretly and at top speed to the Falkland Islands. They reached Port Stanley on December 7, and on the next morning at eight o’clock, Von Spee, in obedience to some inexplicable instinct, brought the whole of his forces to attack the islands. It was the most extraordinary coincidence in the history of war. It was as if a man had been told that a sixty-pound salmon had been seen in a certain river, had thrown a fly at random, and had got a bite and landed him with his first cast. The verdict of Coronel was reversed. Four out of five German ships were sunk. The _Dresden_ escaped, but only to hide herself in the fjords of Patagonia. Germany’s brief spell of sea command in the South Atlantic had ended as dramatically as it began. And within twenty-four hours the laden ships of Chile and the Argentine had put to sea, the underwriters had dropped their premiums to the pre-war rate, and the arrangements for the invasion of South West Africa had begun. Once more it had been proved that the course of sea traffic is governed by sea command, and sea command means the general power to use the ocean for what it truly is, the highway that connects all the ports of the world together. To use, that is to say, exclusively; to limit its use to the power possessing that command, and to those other powers that might be friendly to them, or to neutrals unconcerned with the war altogether. Never in history has this command been complete. From Trafalgar to 1815, the British, if ever, commanded the sea adversely against their enemies. But they lost anything from six hundred to one thousand ships a year, and it was never possible to stop the whole of the enemy’s trade. Before submarines were ever heard of, then, command could not be made absolute. Strangely enough, steam changed all this. To-day the surface command against surface force is virtually absolute. In August, 1914, Germany had in all a dozen armed vessels on the high seas prepared to attack British shipping. They took and destroyed fifty-six vessels only. All but three were destroyed or driven to intern in very few months. Save for a raider or two--exceptions that prove the rule--no surface attack has been made on the Allies’ ocean trade since then. And there has been no ocean trade in German bottoms at all. In a sense, then, the submarine has only restored to the weaker belligerent a part--and only a small part--of the powers he possessed in the days of sailing fleets. It gives him a limited power of attack on his enemy’s supply. But, two cruises of the _Deutschland_ notwithstanding, it has returned him none of his old trading power. And, as the course of the submarine war has shown, so long as he limits the attack on trade to proportions which the neutral world can put up with, the power of attack is so restricted as to be without military value. The attempt, then, to get a kind of command of the sea by
