The Acting Secretary of State to the Mexican Ambassador ( Bonillas )

Excellency: With further reference to Your Excellency’s note No. E–4670 of October 25, 1919, concerning a report to the effect that on October 23rd the crew of a United States Army Aeroplane fired into the town of Nogales, Sonora, I have the honor to say that I am now in receipt of a communication from the branch of this Government to which the matter was referred stating that a careful investigation fails to disclose such an occurrence on October 23rd. I am officially informed, however, that a Lieutenant in the Air Service of the United States Army is being tried by a General Court Martial on the charge of having fired into the town of Nogales on October 19, 1919.

Accept [etc.]
