Where's the "guilt"? The "treason"?
The Andrew Johnson, Amnesty Proclamation, 29 May 1865 required persons seeking the benefits of restored rights and who committed certain specified acts of treasonous rebellion to apply for amnesty and a pardon for those acts specified in the proclamation. Robert E. Lee acknowledged his inclusion in the classes of persons engaged in such rebellion and applied for amnesty and pardon for his commission of such acts when he wrote:
Being excluded from the provisions of amnesty & pardon contained in the proclamation of the 29th Ulto; I hereby apply for the benefits, & full restoration of all rights & privileges extended to those included in its terms. I graduated at the Mil. Academy at West Point in June 1829. Resigned from the U.S. Army April ‘61. Was a General in the Confederate Army, & included in the surrender of the Army of N. Va. 9 April ‘65.
