Letter to General Grant. July 13, 1863
My dear General, I do not remember that you and I ever met personally. I write this now as a grateful acknowledgment for the almost inestimable service you have done the country. I wish to say a word further. When you first reached the vicinity of Vicksburg, I thought you should do what you finally did—march the troops across the neck, run the batteries with the transports, and thus go below; and I never had any faith, except a general hope that you knew better than I, that the Yazoo Pass expedition and the like could succeed. When you got below and took Port Gibson, Grand Gulf, and vicinity, I thought you should go down the river and join General Banks, and when you turned northward, east of the Big Black, I feared it was a mistake. I now wish to make the personal acknowledgment that you were right and I was wrong.
Yours very truly,
A. LINCOLN.
Letter to —— Moulton. Washington. July 31, 1863
My dear Sir, There has been a good deal of complaint against you by your superior officers of the Provost-Marshal-General's Department, and your removal has been strongly urged on the ground of "persistent disobedience of orders and neglect of duty." Firmly convinced, as I am, of the patriotism of your motives, I am unwilling to do anything in your case which may seem unnecessarily harsh or at variance with the feelings of personal respect and esteem with which I have always regarded you. I consider your services in your district valuable, and should be sorry to lose them. It is unnecessary for me to state, however, that when differences of opinion arise between officers of the government, the ranking officer must be obeyed. You of course recognize as clearly as I do the importance of this rule. I hope you will conclude to go on in your present position under the regulations of the department. I wish you would write to me.
