During the first battle of Bull Run the Union troops ran in full retreat back to Washington DC. During this time General Lee told president Davis that give him ten thousand troops and he would capture Washington DC, Davis thought he was kidding and just laughed him off. Had Davis not been mistaken our country might very well be split in half.
That is just one of the massive blunders the South committed during the war. Some of the other problems the South had during the war was lack of unity, unorganized, smaller and towards the end of the war low moral.
Regardless of all else unity was the biggest challenge faced
When you fight a war you need a strong united front. In my mind this added to the feeling of hopelessness in the Southern moral. There size was the South was agricultural in nature while the North was mostly manufacturing. When the confederate was formed the central government. The North"tms big crops were wheat and corn. The South"tms biggest crop was cotton. But without unity no long term victory can be guaranteed. Had the South created a strong front, received foreign support, and achieved strategic victory early in the war they might have won. Further more 15 of the South"tms population were slaves and couldn"tmt be allowed to fight in the war. To make matters worse was South had less then half of the population of the North. This an example of is during Sherman"tms march through Georgia. When the men from Georgia heard the tales of looting, raping, and pillaging the number of deserters were in the thousands. When your government can"tmt pass laws for the good of the many then you have a conflict with unity.
