Southern Transportation during Civil War?
Was in very short supply. Roads an railroady were limited and transportation often moved by river. Most Confederate railroads were either captured, or destroyed. The Southern troops would ambush Union transport trains in the northern Virginia border area.
The Union blockade certainly made the transportation of cotton to England and France a difficult task. However, this was a time without radar and modern sea going vessels. Privateers did help export cotton to Europe. Also, the Northern textile mills needed cotton. With a "permit" issued by the US Treasury Department and through military administrators, cotton trade between the North and South was a factor not to be overlooked.
