After the war, the Lees lived in Powhatan County for a short time before moving to Lexington. Robert E. Lee became president of the Washington College, later renamed Washington and Lee University. Mary Anna Custis Lee visited her beloved Arlington House one last time in 1873, a few months before her death. She was unable to leave her horse carriage due to her debilitating rheumatoid arthritis, hardly recognizing the estate except for a few old oaks and some of the trees that she and Robert had planted.
