File No. 812.00/17593
Mr. Arredondo to the Secretary of State
Mr. Secretary: I am directed by my Government to apprise your excellency, that the office of the First Chief has been informed that the American forces, now in Mexican territory, intend to occupy the town of Casas Grandes, State of Chihuahua, and to say to you formally that as long as there is no agreement concerning the form in which bandits should be pursued along the boundary line, my Government cannot permit the occupation of Mexican towns by American forces, much less such towns as are occupied by our own troops, as this might give rise to frequent conflicts.
With assurances [etc.]
