19. The Union forces had more readily available livestock
The image of the Southern cavalier, mounted on fine horses and outriding his Union counterpart is another enduring myth of the Civil War. The Union held a clear advantage in horses, mules, and oxen, which was apparent both when the armies were on the march and in engagements. At the beginning of the war there were about 3.4 million horses in the states which comprised the Union, with less than half of that number in the states forming the Confederacy. Similar comparisons for other draft animals gave the Union a clear advantage, which only increased throughout the war as the South lost animals which could not be replaced.
