April 7, 1865. General R. E. Lee, the result of the last week must convince you of the hopelessness of further resistance on the part of the Army of Northern Virginia in this struggle. I feel that it is so, and regard it as my duty to shift from myself the responsibility of any further effusion of blood, by asking of you the surrender of that portion of the C.S. Army known as the Army of Northern Virginia.

Letter to Robert E. Lee (1865)
