Recalling the humane and enlightened attitude hitherto assumed by the Imperial German Government in matters of international right, and particularly with regard to the freedom of the seas; having learned to recognize the German views and the German influence in the field of international obligation as always engaged upon the side of justice and humanity; and having understood the instructions of the Imperial German Government to its naval commanders to be upon the same plane of humane action prescribed by the naval codes of other nations, the Government of the United States was loath to believe--it cannot now bring itself to believe--that these acts, so absolutely contrary to the rules, the practices, and the spirit of modern warfare, could have the countenance or sanction of that great Government. It feels it to be its duty, therefore, to address the Imperial German Government concerning them with the utmost frankness and in the earnest hope that it is not mistaken in expecting action on the part of the Imperial German Government which will correct the unfortunate impressions which have been created, and vindicate once more the position of that Government with regard to the sacred freedom of the seas. The Government of the United States has been apprised that the Imperial German Government considered themselves to be obliged by the extraordinary circumstances of the present war and the measures adopted by their adversaries in seeking to cut Germany off from all commerce, to adopt methods of retaliation which go much beyond the ordinary methods of warfare at sea, in the proclamation of a war zone from which they have warned neutral ships to keep away. This Government has already taken occasion to inform the Imperial German Government that it cannot admit the adoption of such measures or such a warning of danger to operate as in any degree an abbreviation of the rights of American shipmasters or of American citizens bound on lawful errands as passengers on merchant ships of belligerent nationality, and that it must hold the Imperial German Government to a strict accountability for any infringement of those rights, intentional or incidental. It does not understand the Imperial German Government to question those rights. It assumes, on the contrary, that the Imperial Government accept, as of course, the rule that the lives of noncombatants, whether they be of neutral citizenship or citizens of one of the nations at war, cannot lawfully or rightfully be put in jeopardy by the capture or destruction of an unarmed merchantman, and recognize also, as all other nations do, the obligation to take the usual precaution of visit and search to ascertain whether a suspected merchantman is in fact of belligerent nationality or is in fact carrying contraband of war under a neutral flag.
