DON ANDRES TREVINO,
Commanding Tamaulipas Troops in Reynosa.
SIR: I have been informed that you, or the forces with which you are acting, have in your possession and power the person of Col. Peter Nickles, a citizen of the Confederate States of America, and that you contemplate having him hung. If he was taken with arms in his hands he is a prisoner of war and entitled to be treated in accordance with the usages of civilized nations. It is represented to me that he was only a spectator and took no part in the contest; in that event there is no cause or justification for his detention. I am confident that you will permit no indignity or outrage to be perpetrated upon the person of Colonel Nickles which would constitute a ,just cause of complaint on the part of the Confederate States, and thus endanger the amicable relations existing between them and Mexico.
I have the honor to be, your obedient servant,
JOHN S. FORD,
Colonel, Commanding.
