By 1863 both sides were aware of the great advantages of strategic railroad lines. Lt. Gen. Braxton Bragg had made skillful use of the railroads in 1862, when he suddenly shifted his army from Mississippi to Chattanooga to begin his drive across Tennessee and into Kentucky. President Lincoln had long recognized the importance of railroads in this area. In the same year Lincoln said, “To take and hold the railroad at or east of Cleveland, in East Tennessee, I think fully as important as the taking and holding of Richmond.” And in 1863 Lincoln wrote Maj. Gen. William S. Rosecrans, “If we can hold Chattanooga and East Tennessee, I think the rebellion must dwindle and die. I think you and [General] Burnside can do this, and hence doing so is your main object.” The armies that traversed this region found it a fertile farming area. East Tennessee’s rich grain fields supplied not only wheat, corn, and hay, but beef, pork, bacon, horses, and mules. It was a vital region for the armies of the Confederacy. It not only supported the troops that occupied that region, but large quantities of provisions were shipped to other armies. In addition to the military and economic reasons, a political factor had to be considered in the struggle for control of East Tennessee. The people there, living in a mountainous area unlike the rest of the State, wished to adhere to the Union. The people maintained their allegiance to the Old Whig party, and there was an attitude of suspicion and distrust toward the Democrats. They were mostly small farmers with little cash income, who had a dislike for the wealthy plantation- and slave-owning class. After fighting broke out at Fort Sumter, neighbors began to take sides. An uneasy truce prevailed until November 1861 when small groups of Union men struck blows at widely dispersed railroad bridges. The cancellation of a projected northern campaign into East Tennessee left the Unionists there without support, and the Confederates took retaliatory measures. Many of the Unionists in East Tennessee fled to Kentucky to enlist in the Union Army; others hid in the mountains. While relief to this section of Tennessee by the Union Army was not to come until 1863, it was not forgotten by President Lincoln.
