The Papers And Writings Of Abraham Lincoln-VOL. VI (Chap. 2.182)
To General Grant.

Executive Mansion, Washington, July 13, 1863.

MAJOR-GENERAL GRANT:

MY DEAR GENERAL:—I do not remember that you and I ever met personally. I write this now as a grateful acknowledgment of the almost inestimable service you have done the Country. I write 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 dropped 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.
