"I have deemed it my duty to say to the Imperial German Government that if it is still its purpose to prosecute relentless and indiscriminate warfare the Government of the United States is at last forced to the conclusion that there is only one course it can pursue; and that, unless the Imperial German Government should now, immediately, declare and effect an abandonment of its present methods of warfare against passenger and freight-carrying vessels this Government can have no choice but to sever diplomatic relations altogether."
It will be noted that the President went further than "liners," and said "passenger and freight-carrying vessels."
In the note sent at this time the President said:
"No limit of any kind has in fact been set to the indiscriminate pursuit and destruction of merchantmen of all kinds and nationalities within the waters constantly extending in area where these operations have been carried on, and the roll of Americans who have lost their lives on ships thus attacked and destroyed has grown month by month until the ominous toll has mounted into the hundreds. Again and again the Imperial German Government has given this Government its solemn assurances that at least passenger ships would not be thus dealt with, and yet it has again and again permitted its undersea commanders to disregard those assurances with entire impunity."
OPPOSED TO SUBMARINE WARFARE.
During all the negotiations the Berlin Foreign Office looked to Count von Bernstorff to prevent a break. His attitude was represented as propitiatory from the viewpoint of the United States and opposed to the submarine warfare of Von Tirpitz. On several occasions he is said to have warned his Emperor personally that a continuance of the warfare against which the United States protested would surely lead to a break. Meanwhile the Ambassador's own position was embarrassed by the operations of German sympathizers in the United States plotting against American neutrality. Some of these operations were traced directly to the military and naval attaches of the embassy, who were withdrawn.
Germany's final note in the Sussex case, received in Washington on May 5, said that "the German naval forces have received the following order":
"In accordance with the general principles of visit and search and the destruction of merchant vessels recognized by international law, such vessels, both within and without the area declared a naval war zone, shall not be sunk without warning and without saving human lives, unless the ship attempts to escape or offers resistance."
Contending that the Imperial Government was unwilling to restrict an effective weapon if "the enemy is permitted to apply at will methods of warfare violating the rules of international law," the note expressed the hope that the United States would "demand and insist that the British Government shall observe forthwith the rules of international law." The communication added:
"Should the steps taken by the Government of the United States not attain the object it (the German Government) desires, to have the laws of humanity followed by all belligerent nations, the German Government would then be facing a new situation in which it must reserve to itself complete liberty of decision."
