Señor Don Matias Romero to William H. Seward, August 3, 1866
Señor Romero to Mr. Seward
Mr. Secretary: In confirmation of the reports I have transmitted to the Department of State of the United States, on divers occasions, relative to the efforts of the French agents in Mexico, to induce citizens of the southern part of the United States to immigrate to that country, animated by a feeling hostile to their government, I have the honor to send you this day an index of original documents containing particulars of plans for that purpose, more minute than any I have yet been able to communicate to your department.
I regret I am not at liberty to say how these documents have fallen into my hands, but I can assure you they are authentic.
I take pleasure in embracing this additional opportunity to renew to you, Mr. Secretary, the assurances of my most distinguished consideration.
Hon. William H. Seward, &c., &c., &c.
