It is important to understand this attitude, not only because it was very general, but because it was the attitude of one of the noblest sons the Republic ever bore, who yet felt compelled, regretfully but with full certitude that he did right, to draw the sword against her. Robert Lee was already recognized as one of the most capable captains in the service of the United States. When it became obvious that General Scott, also a Virginian, but a strong Unionist, was too old to undertake the personal direction of the approaching campaign, Lee was sounded as to his readiness to take his place. He refused, not desiring to take part in the coercion of a State, and subsequently, when his own State became involved in the quarrel, resigned his commission. Later he accepted the chief command of the Virginian forces and became the most formidable of the rebel commanders. Yet with the institution, zeal for which is still so largely thought to have been the real motive of the South, he had no sympathy. Four years before the Republican triumph, he had, in his correspondence, declared Slavery to be "a moral and political evil." Nor was he a Secessionist. He deeply regretted and so far as he could, without meddling in politics--to which, in the fashion of good soldiers, he was strongly averse--opposed the action which his State eventually took. But he thought that she had the right to take it if she chose, and, the fatal choice having been made, he had no option in his own view but to throw in his lot with her and accept his portion of whatever fate might be in store for her armies and her people. Virginia now passed an Ordinance of Secession, and formed a military alliance with the Southern Confederacy. Later she was admitted to membership of that Confederacy, and the importance attached to her accession may be judged by the fact that the new Government at once transferred its seat to her capital, the city of Richmond. The example of Virginia was followed by the other Southern States already enumerated. There remained four Southern States in which the issue was undecided. One of them, Delaware, caused no appreciable anxiety. She was the smallest State in the Union in population, almost the smallest in area, and though technically a Slave State, the proportion of negroes within her borders was small. It was otherwise with the three formidable States which still hung in the balance, Missouri, Kentucky, and Maryland. That these were saved to the Union was due almost wholly to the far-sighted prudence and consummate diplomacy of Abraham Lincoln.
