“Another internal explanation for Confederate defeat has been around for a long time and has recently resurfaced in a number of studies. This one can be described as the ‘lack of will’ thesis. It holds that the Confederacy would have won if the southern people had possessed the determination, the will to make the sacrifices and the total effort necessary to achieve victory. … The main defect of the lack-of-will thesis, as well as of the internal conflict and internal alienation thesis discussed earlier, is that they attribute Confederate defeat to factors intrinsic to the South. Like the analysts of Confederate mistakes at Gettysburg, they tend to forget about the Yankees.”
