"American citizens act within their indisputable rights in taking their ships and in traveling wherever their legitimate business calls them upon the high seas, and exercise those rights in what should be the well justified confidence that their lives will not be endangered by acts done in clear violation of universally acknowledged international obligations, and certainly in the confidence that their own Government will sustain them in the exercise of their rights." This note concluded: "The Imperial Government will not expect the Government of the United States to omit any word or any act necessary to the performance of its sacred duty of maintaining the rights of the United States and its citizens and of safeguarding their free exercise and enjoyment." Germany replied to this note on May 29. It stated that it had heard that the Lusitania was an armed naval ship which had attempted to use American passengers as a protection, and that, anyway, such passengers should not have been present. It added: "The German commanders are consequently no longer in a position to observe the rules of capture otherwise usual and with which they invariably complied before this." To the foregoing the United States maintained in a note sent to the German Government on June 9 that the Lusitania was not an armed vessel and that she had sailed in accordance with the laws of the United States, and that "only her actual resistance to capture or refusal to stop when ordered to do so ... could have afforded the commander of the submarine any justification for so much as putting the lives of those on board the ship in jeopardy." In support of this view the note cited international law and added: "It is upon this principle of humanity, as well as upon the law founded upon this principle, that the United States must stand." Exactly one month later, on July 9, came Germany's reply. Its preamble praised the United States for its humane attitude and said that Germany was fully in accord therewith. Something, it asserted, should be done, for "the case of the Lusitania shows with horrible clearness to what jeopardizing of human lives the manner of conducting war employed by our adversaries leads," and that under certain conditions which it set forth, American ships might have safe passage through the war zone, or even some enemy ships flying the American flag. It continued: "The Imperial Government, however, confidently hopes the American Government will assume to guarantee that these vessels have no contraband on board, details of arrangements for the unhampered passage of these vessels to be agreed upon by the naval authorities of both sides." It is to this reply that the note of the United States Government made public on July 24 is an answer.
