The issue in Lee's mind was not the existence of slavery. He had long been in favor of emancipation, and Virginia had more than once come so close to abolishing slavery by law that its disappearance from her borders was practically assured within a very short period. All his own slaves he had long since freed and he was gradually emancipating his father-in-law's, according to the directions of Mr. Custis's will. But the right of each state to govern itself without interference from the Federal Government seemed to Lee essential to the freedom of the people. He recognized, however, that secession was revolution and, calmly and conscientiously examining the question, he concluded that, if force were used to compel any state to remain in the Union, resistance would be justifiable. Most Virginians reached this decision impulsively, light-heartedly, defiantly or vindictively, and more or less angrily, according to their temperaments and the spirit of the times, but not so Lee. He unaffectedly prayed God for guidance in the struggle between his patriotism and his devotion to a principle which he deemed essential to liberty and justice. He loved his country as only a man in close touch with its history and with a deep reverence for its great founder, Washington, could love it; he had fought for its flag; he wore its uniform; he had been educated at its expense; and General Scott, the Commander of the army, a devoted Union man, was his warm personal friend. Patriotism, personal pride, loyalty and even gratitude, therefore, urged him toward the support of the Union, and only his adherence to a principle and the claims of his kinsmen and friends forbade. For a time Virginia resisted every effort to induce her to cast her lot with the Confederacy. Indeed she actually voted against secession when the question was first presented. But when Fort Sumter resisted attack on April 12, 1861, and the President called upon the various states to furnish troops to enforce the national authority, practically all affection for the Union disappeared and by a decisive vote Virginia determined to uphold the Southern cause.
