File No. 701.5212/4.

The Spanish Ambassador to the Secretary of State.

My dear Mr. Secretary. Confirming the conversation I had with you this morning over the telephone, I beg to inform you that according to a telegram which I have received from the Spanish Minister in Mexico, dated today, the arrest of Angel Caso, a Spanish subject and Confidential Agent of the Spanish Government to General Villa, was attempted yesterday evening at Mexico City, under instructions from General Obregon, who has assumed command of the capital.

The gravest fears are entertained by the Spanish Minister in Mexico for the life of Sr. Caso, and he asks me to appeal to your good offices in order to obtain from General Carranza the necessary guaranties for the protection of the person, family, house and property of Sr. Angel Caso.

I beg to recommend this request personally to your earnest consideration, in the hope that you will do everything in your power to secure the protection of this Spanish subject, whose life appears to be in extreme danger.

Believe [etc.]

Juan Riaño.
