At the outbreak of the Civil War he was so highly esteemed as an officer in the United States army, that he would have been appointed commander of the Union armies if he had been willing to accept the position. He loved the Union, and was opposed to secession, but when Virginia, his native State, seceded he felt that it was his duty to go with her. [Illustration: Lee's Home at Arlington, Virginia.] His struggle in making the decision was a painful one, as was made plain in a letter he wrote to a sister, then living in Baltimore. "With all my devotion to the Union," he said, "and the feeling of loyalty and duty of an American citizen, I have not been able to make up my mind to raise my hand against my relatives, my children, my home. I know you will blame me, but you must think as kindly of me as you can, and believe that I have endeavored to do what I thought right." Soon after he decided that he must go with Virginia in the great struggle which was to follow, he accepted the command of the Virginia State forces, and within a year from that time became military adviser of Jefferson Davis, who was President of the Confederacy. [Illustration: Jefferson Davis.] In 1862, the second year of the war, Lee took command of the leading Confederate army in Virginia. General McClellan, who commanded a large Union army, had been trying to capture Richmond, the capital of the Confederate States. After fighting a series of battles, he approached so close to Richmond that his soldiers could see the spires of the churches. But as the city was strongly fortified he retreated to the James River. During this retreat, which lasted a week, were fought what were known as the "Seven Days' Battles." Having thus saved Richmond from capture, Lee marched north into Maryland, expecting the people to rise and join his forces. But they were loyal to the Union and refused. The terrible battle of Antietam or Sharpsburg was fought (September, 1862), and Lee was obliged to retreat to Virginia. A few months later (December, 1862), Lee repulsed an attack of the Union army at Fredericksburg with fearful slaughter, and in the following May he won a victory at Chancellorsville.
