8,100 and 37,900, respectively), plus Charleston, much of which was destroyed in an accidental fire in 1861. These eleven contained 115,900 people in the 1860 census, or 14% of the urban South. Historians have not estimated their population when they were invaded. The number of people who lived in the destroyed towns represented just over 1% of the Confederacy's population. In addition, 45 courthouses were burned (out of 830). The South's agriculture was not highly mechanized. The value of farm implements and machinery in the 1860 Census was $81 million; by 1870, there was 40% less, or $48 million worth. Many old tools had broken through heavy use and could not be replaced; even repairs were difficult. The economic calamity suffered by the South during the war affected every family. Except for land, most assets and investments had vanished with slavery, but debts were left behind. Worst of all were the human deaths and amputations. Most farms were intact but most had lost their horses, mules and cattle; fences and barns were in disrepair. Prices for cotton had plunged. The rebuilding would take years and require outside investment because the devastation was so thorough. One historian has summarized the collapse of the transportation infrastructure needed for economic recovery: One of the greatest calamities which confronted Southerners was the havoc wrought on the transportation system. Roads were impassable or nonexistent, and bridges were destroyed or washed away. The important river traffic was at a standstill: levees were broken, channels were blocked, the few steamboats which had not been captured or destroyed were in a state of disrepair, wharves had decayed or were missing, and trained personnel were dead or dispersed. Horses, mules, oxen, carriages, wagons, and carts had nearly all fallen prey at one time or another to the contending armies. The railroads were paralyzed, with most of the companies bankrupt. These lines had been the special target of the enemy. On one stretch of 114 miles in Alabama, every bridge and trestle was destroyed, cross-ties rotten, buildings burned, water-tanks gone, ditches filled up, and tracks grown up in weeds and bushes. ... Communication centers like Columbia and Atlanta were in ruins; shops and foundries were wrecked or in disrepair. Even those areas bypassed by battle had been pirated for equipment needed on the battlefront, and the wear and tear of wartime usage without adequate repairs or replacements reduced all to
