DOUAY, General Com’dg First Division of Infantry of Mexican Expeditionary Corps to A. Viezca , Parral, July 12, 1866

Government and military commandancy of the state, Parras, July 24, 1866.

General: I have the honor to acknowledge the receipt of your letter of the 8th of July, containing the copy of an official document relative to the proposed exchange of French prisoners taken at Santa Isabel and Parral. The great desire I had to carry out this humane negotiation, of advantage to the whole world, makes me lament that the said letter on exchange of prisoners contains conditions which render it impossible for me to accept, or even discuss it. All I can do is to refer it to the marshal commander-in-chief.

I will not close this letter without thanking you for the interest you have taken in this matter, and begging you to accept the assurances of my high consideration.
