Ohio, to the court of
Juarez, the President-elect of Mexico, which country was still in
possession of the Emperor Maximilian, supported by a corps of
French troops commanded by General Bazaine. General Grant denied
the right of the President to order him on a diplomatic mission
unattended by troops; said that he had thought the matter over,
world disobey the order, and stand the consequences. He manifested
much feeling; and said it was a plot to get rid of him. I then
went to President Johnson, who treated me with great cordiality,
and said that he was very glad I had come; that General Grant was
about to go to Mexico on business of importance, and he wanted me
at Washington to command the army in General Grant's absence. I
then informed him that General Grant would not go, and he seemed
amazed; said that it was generally understood that General Grant
construed the occupation of the territories of our neighbor,
Mexico, by French troops, and the establishment of an empire
therein, with an Austrian prince at its head, as hostile to
republican America, and that the Administration had arranged with
the French Government for the withdrawal of Bazaine's troops, which
would leave the country free for the President-elect Juarez to
reoccupy the city of Mexico, etc., etc.; that Mr. Campbell had been
accredited to Juarez, and the fact that he was accompanied by so
distinguished a soldier as General Grant would emphasize the act of
the United States. I simply reiterated that General Grant would
not go, and that he, Mr. Johnson, could not afford to quarrel with
him at that time. I further argued that General Grant was at the
moment engaged on the most delicate and difficult task of
reorganizing the army under the act of July 28, 1866; that if the
real object was to put Mr. Campbell in official communication with
President Juarez, supposed to be at El Paso or Monterey, either
General Hancock, whose command embraced New Mexico, or General
Sheridan, whose command included Texas, could fulfill the object
perfectly; or, in the event of neither of these alternates proving
satisfactory to the Secretary of State, that I could be easier
spared than General Grant. "Certainly," answered the President,
"if you will go, that will answer perfectly."

Lewis D. Campbell, Minister to Mexico, dated October 25, 1866; a
