A great naval battle was fought in the North Sea off Jutland, where, in the afternoon and evening hours of May 31, 1916, the fleets of England and Germany clashed in what might have been--but was not--the most important naval fight in history. Why it missed this ultimate distinction is not altogether clear. Nor is it altogether clear to which side victory leaned. To pronounce a satisfactory judgment on this point we need far more information than we have at present, not only as to the respective losses of the contending fleets, but as to the objects for which the battle was fought and the degree of success attained in the accomplishment of these objects. The official German report states that the German fleet left port "on a mission to the northward." No certain evidence is at hand as to the nature of this mission; but whatever it was, it can hardly have been accomplished, as the most northerly point reached was less than 180 miles from the point of departure, and the whole fleet, or what was left of it, was back in port within thirty-six hours of the time of leaving. It has been surmised, and there is some reason to believe, that the German plan was to force a passage for their battle cruisers through the channel between Scotland and Norway into the open sea, where, with their high-speed and long-range guns, they might, at least for a time, have paralyzed transatlantic commerce with very serious results for England's industries, and still more serious results for her supplies of food. Another and a somewhat more plausible theory is that the plan contemplated the escape to the open sea, not of the battle cruisers themselves, but of a number of very fast armed merchant cruisers of the _Moewe_ type, which were to repeat the _Moewe's_ exploit on a large scale, serving the same purpose that the submarines served during the period of their greatest activity. Color is lent to this theory by what is known of the controversy now going on in Germany between those who advocate a renewal of the submarine warfare against commerce, and those who are opposed to this. It is evident that if fast cruisers could be maintained on England's trade routes they might do all that the submarine could do and more, and this without raising any question as to their rights under international law. Whatever the plan was, we must assume that it was thwarted by the interposition of the British fleet; and from this point of view the battle takes on the aspect of a British victory. The German fleet is back behind the fortifications and the mine fields of the Helgoland Bight, in the waters which have been its refuge for nearly two years of comparative inactivity. And the British fleet still holds the command of the sea with a force which makes its command complete, and, in all human probability, permanent.
