The President naturally felt a special interest in the attitude of his native state, Kentucky. That attitude would have perplexed and embarrassed a less discerning statesman. Taking her stand on the dogma of State Sovereignty Kentucky declared herself "neutral" in the impending war between the United and Confederate States, and forbade the troops of either party to cross her territory. Lincoln could not, of course, recognize the validity of such a declaration, but he was careful to avoid any act in open violation of it. Sometimes openly and sometimes secretly he worked hard to foster, consolidate, and encourage the Union party in Kentucky. With his approval and probably at his suggestion loyalist levies were voluntarily recruited on her soil, drilled and prepared for action. But no Northern troops were sent across her frontier. He was undoubtedly working for a violation of Kentuckian "neutrality" by the other side. Circumstances and geographical conditions helped him. The frontier between Kentucky and Tennessee was a mere degree of latitude corresponding to no militarily defensible line, nor did any such line exist to the south of it capable of covering the capital of Tennessee. On the other hand, an excellent possible line of defence existed in Southern Kentucky. The Confederate commanders were eager to seize it, but the neutrality of Kentucky forbade them. When, however, they saw the hold which Lincoln seemed to be acquiring over the counsels of the "neutrals," they felt they dared not risk further delay. Justifying their act by the presence in Kentucky of armed bodies of local Unionists, they advanced and occupied the critical points of Columbus and Bowling Green, stretching their line between them on Kentuckian soil. The act at once determined the course of the hesitating State. Torn hitherto between loyalty to the Union and loyalty to State rights, she now found the two sentiments synchronize. In the name of her violated neutrality she declared war on the Confederacy and took her place under the Stars and Stripes. The line between the two warring confederations of States was now definitely fixed, and it only remained to try the issue between them by the arbitrament of the sword. At first the odds might seem very heavy against the Confederacy, for its total white population was only about five and a half million, while the States arrayed against it mustered well over twenty million. But there were certain considerations which tended to some extent to equalize the contest.
