Moreover, the British Government has supplied arms to British merchant ships and instructed them forcibly to resist German submarines. In these circumstances, it would be very difficult for submarines to recognize neutral merchant ships, for search in most cases cannot be undertaken, seeing that in the case of a disguised British ship from which an attack may be expected the searching party and the submarine would be exposed to destruction. Great Britain, then, was in a position to make the German measures illusory if the British merchant fleet persisted in the misuse of neutral flags and neutral ships could not otherwise be recognized beyond doubt. Germany, however, being in a state of necessity, wherein she was placed by violation of law, must render effective her measures in all circumstances, in order thereby to compel her adversary to adopt methods of warfare corresponding with international law, and so to restore the freedom of the seas, of which Germany at all times is the defender and for which she today is fighting. Germany therefore rejoices that the United States has made representations to Great Britain concerning the illegal use of their flag, and expresses the expectation that this procedure will force Great Britain to respect the American flag in the future. In this expectation, commanders of German submarines have been instructed, as already mentioned in the note of Feb. 4, to refrain from violent action against American merchant vessels, so far as these can be recognized. In order to prevent in the surest manner the consequences of confusion--though naturally not so far as mines are concerned--Germany recommends that the United States make its ships which are conveying peaceful cargoes through the British war zone discernible by means of convoys. Germany believes it may act on the supposition that only such ships would be convoyed as carried goods not regarded as contraband according to the British interpretation made in the case of Germany. How this method of convoy can be carried out is a question concerning which Germany is ready to open negotiations with the United States as soon as possible. Germany would be particularly grateful, however, if the United States would urgently recommend to its merchant vessels to avoid the British naval war zone, in any case until the settlement of the flag question. Germany is inclined to the confident hope that the United States will be able to appreciate in its entire significance the heavy battle which Germany is waging for existence, and that from the foregoing explanations and promises it will acquire full understanding of the motives and the aims of the measures announced by Germany. Germany repeats that it has now resolved upon the projected measures only under the strongest necessity of national self-defense, such measures having been deferred out of consideration for neutrals.
