The Italian Ambassador (Macchi di Cellere) to the Secretary of State

My Dear Mr. Secretary of State: As I have had the pleasure of informing you by my letter of January 22d, I did not fail to transmit to my Government the communication you kindly addressed to me on January 19, calling their attention to the considerations contained therein and to the propositions concerning the defensive armament of merchantmen.

The Royal Government have carefully examined the important questions involved, as you will have noticed also from the preliminary considerations submitted to the American Ambassador at Rome on February 19, and after having proceeded to an exchange of views with the Allied Governments have now formulated their final reply to the American proposal, of which in conformity with the instructions received, I hasten to transmit the text to you herewith.

Believe me [etc.]

Macchi di Cellere
[Enclosure—Translation]

The Royal Italian Government have already had the honor of submitting to the American Ambassador at Rome in a note verbale dated February 10, their considerations regarding the proposal concerning armed merchantmen made on January 19 by the American Government to the representatives of the Allied Governments in Washington.

After an exchange of views with the Allied Governments, the Italian Government have now the honor to communicate to the American Government their final answer on the question.

His Majesty’s Government feel they could not but confirm the views expressed in their note verbale of February 19. Submarine warfare as practiced up to now by the Austro-Hungarian Government and their allies implies a violation of those principles of international law and humanity which it is a strict duty of belligerents to respect, whatever may be the instruments of war of which they avail themselves. This violation has been the cause of serious and illegal damage to the persons and property both of belligerent and neutral nations.

It is superfluous to recall the case of the Ancona which was sunk under circumstances which the Austro-Hungarian Government themselves have been unable to deny.

The Italian Government consider it, therefore, impossible to renounce a legal means of protection which has been recognized by international law and which is used by Italian merchantmen for exclusively defensive purposes. The American Government themselves have, at the beginning of the war, expressed a similar point of view. It would, furthermore, not be in accordance with the principles recognized by the Hague conventions, that the rules approved by them should be changed during the course of the war.

Although appreciating the highly humanitarian sentiments which have inspired the American suggestion, the Italian Government feel that, in view of the above considerations, they could not give their adhesion to the American Government’s proposal, which would practically put merchantmen at the mercy of submarines by depriving them of their only means of defense and is based upon the sole obligation to provide for the safety of passengers, an obligation which the submarines cannot fulfil in practice, owing to their lack of adequate means to this end.
