School. Lee was well liked by the students, which enabled him to announce an "honor system" like that of West Point, explaining that "we have but one rule here, and it is that every student be a gentleman." To speed up national reconciliation Lee recruited students from the North and made certain they were well treated on campus and in town. Several glowing appraisals of Lee's tenure as college president have survived, depicting the dignity and respect he commanded among all. Previously, most students had been obliged to occupy the campus dormitories, while only the most mature were allowed to live off-campus. Lee quickly reversed this rule, requiring most students to board off-campus, and allowing only the most mature to live in the dorms as a mark of privilege; the results of this policy were considered a success. A typical account by a professor there states that "the students fairly worshipped him, and deeply dreaded his displeasure; yet so kind, affable, and gentle was he toward them that all loved to approach him. ... No student would have dared to violate General Lee's expressed wish or appeal." While at Washington College, Lee told a colleague that the greatest mistake of his life was taking a military education. He also defended his father in a biographical sketch. President Johnson's amnesty pardons On May 29, 1865, President Andrew Johnson issued a Proclamation of Amnesty and Pardon to persons who had participated in the rebellion against the United States. There were fourteen excepted classes, though, and members of those classes had to make special application to the president. Lee sent an application to Grant and wrote to President Johnson on June 13, 1865: On October 2, 1865, the same day that Lee was inaugurated as president of Washington College in Lexington, Virginia, he signed his Amnesty Oath, thereby complying fully with the provision of Johnson's proclamation. Lee was not pardoned, nor was his citizenship restored. Three years later, on December 25, 1868, Johnson proclaimed a second amnesty which removed previous exceptions, such as the one that affected Lee. Postwar politics Lee, who had opposed secession and remained mostly indifferent to politics before the Civil War, supported President Andrew Johnson's plan of Presidential Reconstruction that took effect in 1865–66. However, he opposed the Congressional Republican program that took effect in 1867. In February 1866, he was called to testify before the Joint Congressional Committee
