The concluding passage of the above cited report had already been anticipated by me in a telegraphic communication in which I begged the ambassador with all possible energy to urge the political arguments opposed to the unrestricted U-boat warfare, which is proved by a telegram from Hohenlohe on January 13 as follows: Reply to yesterday's telegram No. 15. In accordance with the telegram mentioned, and after discussing it with Baron Flotow, I went to the Secretary of State--not being able to see the Chancellor to-day--and in conformity with Your Excellency's intentions called his attention to the fact that we should participate in the results of the U-boat war just as much as Germany and that, therefore, the German Government is bound to listen to us also. All the leading German statesmen know that Your Excellency, during your stay here, expressed _yourself as opposed to the movement_, but that I had come once more as Your Excellency's representative to repeat the _warning against too hasty action_. I further emphasised all the arguments against the U-boat warfare, but will not trouble Your Excellency with a repetition of them, nor yet with the counter-arguments, already known to Your Excellency, that were put forward by the Secretary. I gave a brief summary of both these standpoints in my yesterday's report No. 6 P. Herr Zimmermann, however, laid special stress on the fact that the information he was receiving convinced him more and more that America, especially after the Entente's answer to Mr. Wilson, which was in the nature of an insult, would very probably not allow it to come to a breach with the Central Powers. I did all I possibly could to impress upon him the responsibility Germany was taking for herself and for us by her decision in this question, pointing out very particularly that before any decision was arrived at our opinion from a nautical-technical standpoint must also be heard, in which the Secretary of State fully concurred. I have the feeling that the idea of carrying out the U-boat warfare is more and more favourably received, and Your Excellency had the same impression also when in Berlin. The last word as to the final attitude to be adopted by the German Government will no doubt come from the military side. In conformity with the instructions received, _I will nevertheless uphold with all firmness the political arguments against the U-boat warfare_. Baron Flotow will have occasion to meet the Secretary of State this afternoon. I had sent Baron Flotow, a Chief of Department, to Berlin at the same time, in order that he might support all Hohenlohe's efforts and spare no pains to induce Germany to desist from her purpose. Flotow sent me the following report on January 15:
