March 9, 1864

General Grant The nation's appreciation of what you have done, and it's reliance upon you for what remains to do, in the existing great struggle, are now presented with this commission, constituting you Lieutenant General in the Army of the United States. With this high honor devolves upon you also, a corresponding responsibility. As the country herein trusts you, so, under God, it will sustain you. I scarcely need to add that with what I here speak for the nation goes my own hearty personal concurrence.
