On April 18, 1861 Lee was offered field command of the United States Army. On the following day, he received word that Virginia had seceeded from the Union; he submitted his letter of resignation from the United States Army on April 20. Three days later, Lee accepted the position of commander of Virginia forces. From this point onward, Lee's identity became intrinsically linked to the Confederate cause. At the age of 55, on May 31, 1862, Robert E. Lee was assigned to command the troops which he named "The Army of Northern Virginia". During the Civil War he worked closely with Jefferson Davis, J.E.B. Stuart. He is best known for his victories in the Battle of second Manassas (second Bull Run), and the Battle of Chancellorsville. Named General-In-Chief of all Confederate Armies on February 6, 1865, his tenure in this position was cut short by his surrender to General Grant at the Appomattox Court House on April 9, 1865, thus ending the Civil War.
After the war, Lee returned to Richmond. During the last five years of his life, he served as President of Washington College in Lexington, Virginia, and he was indicted for treason though never brought to trial. Lee was stricken on September 28, 1870 in Lexington and died a few weeks later on October 12. Robert E. Lee was buried in Lexington and remembered as an educator, a soldier, and a Christian gentleman who lived his life with dignity. Lee has been compared to General George Washington in terms of the respect which he earned from his soldiers, his region, and the nation.
