File No. 763.72/3856
The Bolivian Minister ( Calderon) to the Secretary of State
Sir: I have the honor to inform your excellency that my Government, on yesterday, delivered his passports to the German Minister and declared the diplomatic relations between Bolivia and the German Empire to be broken off.
When my Government received the communication of the Imperial Government of Germany relative to the unrestricted use of its submarines, it not only protested against such a resolution but declared that on this question it stood with the Government of the United States in defense of the neutral rights and the laws of mankind ignored by the German Government. The rupture of relations consummated to-day is the natural consequence of the attitude taken by Bolivia which gladly sides with the Government of the United States in the holy cause of the defense of right and justice against the mastery of force and violence.
I avail myself [etc.]
